A

See anything yeah, okay, let's start! uh First of all, I wanted to talk about xavro map for this year. You can find it. If you go to the express com, then go to blogs and go to roadmap, and here you can see you can see all the planes for xf fin forms every devexpress product.

A

Here you can find xlf, and today I wanted to quickly demonstrate a few features we are working on. Some of them are ready and the first feature is uh support seo. As you know, uh in the current version, um xf supports only uh one language localization I mean you can't select multiple languages for your application or you have to write a code in the upcoming 20.

A

2.6 version will have will provide the capability to localize xf blazer applications like you used to do this in wind forms and web phones and in 21.1.

A

You will also have the capability to change language at runtime like this, for example, you can see that there is a tiny selector with languages like let's practice, german.

A

Or russian and you can also change languages if you log in take special note of the following: okay, sorry all the following menu, so you can change your language from here as well.

A

So it's now russian or german.

A

So you'll have this in 21.1 version. Also. I want you to promote small features that will be released in.

A

20.2.6 in two weeks, I hope it's support for action container view item, so you can by default, you can place actions in main menu and you can also with with this feature you can play sections in layout like here.

A

Another small feature: it's support for time, span property editor, so you can specify some time like this. Using this tiny selector.

A

Well- uh and the last thing uh I wanted to show- is uh it's not only about xf but about device press in general? As you probably know, uh we currently have two installers one for dotnet framework and the other one is for net core desktop.

A

That includes winforms and wpf libraries for net core and dot net five, and in may we will have. uh We will add these um dotnet coiving forms and wpf assemblies into our main uh dotnet framework installer. So it will be easier for for you to get all libraries from one installer and the second installer will will stay as sts, because we have some wpf customers or winfroms customers that uh use only these dot net core 1.5 technologies. So they may not need any blazer or devex stream or other web technologies, so for xaf.

A

I think the majority of users will benefit from this change, because there is one installer, not two and uh also how it affects you.

A

Many asked us to provide to make it easier to create winforms and blazer applications simultaneously, and you have this capability in 21.1.

A

So here you can see that there is a new project, template it's for net core and uh the other one is for for that net framework. And if you choose this one for net core you, if you run it, let's click create you will uh you can choose both winforms and blazer?

A

Let's click next here you can select either entity framework core or our.

A

Experiment, let me skip and click finish and as a result, you have you have a single solution that includes both winforms and blazer. As many of you want.

A

Let me wait to beat some somethingness not responding in the visual studio.

A

But you can trust me.

B

He is a demogod, you know.

A

Yeah, I I had a created it just before the presentation and it worked quickly.

A

So here you can see you have a blazer and wind forms and also common module, and it's exactly as you have in winfroms and reference for example, and also you you'll be able to add a new module. Let me choose like this, so we updated this wizard as well.

A

I think that's it for me: okay, okay,.

C

Stuff dennis one one, one quick question is: is the new uh winforms, so is it this new wizard? Is this like? Is it targeting uh full framework for desktop, or is it like the new.net core.

A

Version, uh no, no! It's uh the new.net coil because uh it includes blazer laser okay,.

C

A

C

Let's just trust the question: yeah.

A

The old one uh stays uh the old one, I mean dotnet framework, it stays as it is because it's widely used- and I think it will be used for many years to.

D

A

Waveforms is also not going anywhere, it stays as as before, because many users rely on it and it's good and we are proud of it.

C

Yeah, it was just a question, but what the what the perspective is, looks awesome.

A

Okay, thank you guys.

B

Thank you dennis we're looking forward for those features when we have the new installer so well, now it's my turn. um So uh what I'm going to show you guys is some open source project that we have um is usually easier to to use something open source and to make it something open source. We were talking about that before. So, let's see which screen I'm sharing so just one sec zoom the share screen and I want to share screen number two great.

B

So can anyone see my screen now? Can anyone confirm manuel, maybe confirm yeah, so you're watching you're, seeing the github page right? So uh what they have here is the is a combination of modules that I have done for for basically some of the customers.

B

The ideas came from actually several customers that we have and I decided okay. This is common between all of them. Let's make it public and they agree with it. So here we have the the main page for the ultra modules. There is only like three modules actually, um but the one that I want to show you is the one that we get most requested for, which is the universal search. So here I have a soft solution. Let me close all of this, and basically this is the model that I'm going to show you today.

B

It's an agnostic module, so the idea about universal search is that you want to do a search within all your applications. Every part of your application or the domain objects that you want to expose to to your user. So um this is like really really easy to implement. Basically, you only have one attribute um that you will use in basically most of the classes.

B

So if you want to implement that, for example, you can add this decoration to your class- and you can tell it like once the object is found which properties you want to display, and then you can also include like um as a format string. So this is how the result will show when it shows on the list of results, so it will show the customer code and the customer name and where that customer is from.

B

So that's the thing that you need to make to make your object searchable in general, so beside that it should work mostly like the normal searching stuff. So let me run.

B

B

And let's login.

B

So here is the data that I have so far. I have countries and I have customers, so these both of these classes are marked with universal search attributes. So if I want to search over them, I go to universal search icon here in the navigation item and basically, this replace soft search in general.

B

So, for example, let's go to the data right now, let's check the customers. Let's see, we have a few customers from. We have alexander pushkin from russia here in anacarena, so some famous characters, and basically, uh let's look for something.

B

For example, here cristoval perez he's from chile and also we have chile in the country list, so I can go to universal search and search for the word, chile and see I got four records. One is a country object and the other one are customers, and here is the format string. So basically it's a white application search. So it's really useful when you want to locate anything something in your application and you don't know exactly which entity it is or you're.

B

Looking uh for a text in your whole application- and the neat thing about this is first, this agnostic is not platform oriented, so it will work on a web or windows and also is that, for example, here we have two different type of objects right in the same list, so the model, what is doing is basically is remapping the default action. So when I double click in a result, I will go to that detailed view.

B

So, for example, here I have the little view for country and when I open a customer, I have the detailed view for customers, and this is the customer that I'm seeing here in the record. So I think that this is something that can be really productive if you have a really wide application with a lot of entities and you want to search like through all of them.

B

So that's why we get a lot of requests for this and most of the time I tell the people just stay the code is there it's free and it's open source, so just go and get it because we are not compiling at the moment, the newest for each version, because that is a lot of work in general. We do it from time to time, but but only when it's needed. So if you need to get something from ultra, just go and get the code or you compile it yourself.

B

So this is the first one that we get a lot of requests for, and that is this uh just.

C

A quick thing, I, I think, that's a that's a really good good module, because uh I can uh imagine something like this um when you have like a help desk system or people calling in your office, and they are not 100 sure uh where to find the last bit of information or something like this. They go to the screen or some kind of the screen, because it's exactly if it's it's it's modular enough, so you can reuse it in in another context.

C

But uh if you get called and have no idea where to find the information quickly, I can do a whole search on.

B

On the application and get to the right data and also is because we have another module, that is internal, that is an activity stream like a facebook wall. So then you need to do broad searches in general yeah. So this uh module is useful for that and whatever you want to include you just decorate. It set the properties and, let's say.

D

B

You want to format it and that that's it I mean there are possibilities to making this better, but.

C

But there is a question from gp uh when the customer has hundred a thousand plus records with the result be a thousand plus entries or a thousand plus orders.

B

For example, well, uh I was thinking about that just this morning before the demonstration and yes, what we need to do is like um put some citizen screen here to to set like okay. I want the first page of all the results. I want the second page because otherwise, at the moment, it's returning. Basically, everything in windows form with local database is not a problem, but if you have a remote database that can be slower.

B

So um basically we want to add some options like bring me everything bring me everything that is happening, so we can make it faster. I mean so far is the search for generality that we have, but we want to make it better. Actually, um I'm pretty writing this module, uh but questions like fight fight score.

C

Is like the the uh the question.

B

C

B

So I think I think we get we get the point yeah also jp, if you want to give me a hand with this module. uh Let's work on this together, I mean this is like quite fun to have it and I think it's really useful. So uh basically I will I'm working on that. I was working on that this morning. I want to release a new version. uh I wanted also to make a version for xpo pure xpo in general, because I have some applications that are pure uh xpo and laser.

B

So I want to have this functionality because I, like it a lot so, okay, that is different. I will I will on the chat yeah, so thanks man, so the second.

E

Module. uh Sorry sorry.

B

E

uh Hello is possible and custom for only six, but thanks business object entity which, for the four years in.

B

All businesses, no actually is I'm only searching in the one that have this declaration, the universal search attribute. So you don't need to do. I mean this will not search in all the entities in your staff application. It will search only in the entities that you register with the with this attribute. So maybe you don't want to show something that is like, maybe forbidden to see, maybe some private data. So you don't. If you don't put this, it will not be included on the search.

B

Basically, so that's the idea. If you want to show it, you put the decoration, if you don't want to show it, uh you just leave it as it is so, okay, let's move forward with another module, and I got a lot of requests for this one and also this is not part of the ultra module. So far I mean there is a different version. We used to have a scripting module that compiles a c-sharp assembly that you can use in your application, but that approach was like too difficult to maintain.

B

So now we have the gene machine. So, basically, gene is a javascript engine that is able to interact with the runtime of.net, so you can write javascript code that will execute dotnet code in the end. So here I have some examples of it. I mean when I wrote this.

B

I was getting crazy because I liked this idea so much that I could not stop working about it or thinking about you know how it is when you get possessed by the idea. So um let's wait for this to load and let's see what we have here.

B

So let's wait a little bit okay, so the idea of the gene machine or is to be able to create the scripts and then interact with soft parts. So, for example, let me close all of these tabs. So this is what we have so far. We have three type of scripts general scripts. uh We have property editor scripts and then we have state machine scripts that you know. I know that the state machine is the most beloved module in stuff, at least for me.

B

So let's start with something like really simple, um for example, which one is a small one.

B

Show message: I hope that this works, because this actually have a problem when I'm when I'm running zoom, when I'm sharing my screen, it just follow the notifications. So, let's see, if today this will work so really simple script. I only have one one function that is called show message.

B

Then I have the the text that I want to show and the type of notification and for how long I want to show it and for this I'm using the rich text editor from from developer express. So it's really nice because you can do stuff like this. You can change colors in in in your code. So I like this more than visual studio in general.

B

I wish I can have like auto completed intellisense here, but since you can have all the type of colors that you want, it's also really really nice. For example. If I want to make this another color, I can just make it. I don't know red.

B

Oh it didn't see, it didn't work, it's like the demo effect, but anyway. So let me run this script and let's see how it goes yeah here we have the notification. So whatever you can you do, you can have some output, you can have the output here or you can interact with some parts from stuff. So let me show you some more complicated scripts.

B

So, for example, let me show you the: let's see the person object. We have one person here, but it says person from javascript, so let's go and find that script. We have this script here like create object and instance.

B

So, let's see this is what we have here. So we get the type we send the full type. Then we create an object space. Then we figure out the we create the object, the instance and then we set the values and then we commit the changes and show a notification in the end. So every like all the code is encapsulated in this function and then we are calling this function. So just for the purpose of this demo, I'm going to change this and it will be suff community stand up.

B

So, let's save this and let's run it so success and let's go to the person's object, and let's refresh this so here we have the records created by javascript in the end, so we have a little bit more complicated examples. For example, let's see here you can do an http request. Basically, you can interact with all the.net runtime.

B

So here what I have is we get an http client, then, with this client we make a request to this. Url, basically, is a demo url. You will always get the same json and then we log the status and we lock the response. So if we execute this here, we have the json that this call will return anyway, and we have like uh one other example that I want to show you, that is the get secure, object space uh provider.

B

So this one is really neat because here I'm getting an object space that is impersonated as an admin, so you can tell it okay, login as this user and get this object space. So you will have those permissions for this object space and, for example, then after we get the object space, we can create an object, and basically this will use soft permissions in the end. So I'm going to create one object as an admin and then I'm going to change to another user.

B

So you see that it will be forbidden by the by the security system, so this will be person from admin user.

B

So let's execute this and it's working and if we go to, if we go to the person list- and we refresh this here- we have the person from the admin user.

B

But if we change this to user, which doesn't have permissions to create anything- and we execute this- see we're getting an exception and is that is prohibited by the security system rules, so the scripts can work along with basically everything that is inside of stuff. So this is good because you can tell run this script as the admin or run this script as salesperson or as this person in general.

B

Also, we have some scripts. Let's come here like.

B

That can interact with the ui, for example, this script will get the controller.

B

This is the full name of the controller that I want to get from saf and then from that controller I want to get the simple action one and I will change the caption to caption from javascript, so that action is actually if we come here. Is this dummy action? So if I execute this script, I would change the caption for this. So let's execute it see and I change the captions, so you can do a lot of stuff with those script in, like, I think, they're really useful in general.

B

So let's see what else do we have here? uh Well, you can make an action um out of these um out of this escape. So, for example, let's see what we have. We have the show message, actions right. So let's make this script an action, so this script should be an action uh it will be for, let's see, where do we put it? Let's put it in the person object and I want to show it in the detail view. So let me save this save and close.

B

So let me close all the tabs, I I'm not a tough person if you go to the person object here. The action is not showing right because it's the is the list view. But if we go to the detail view uh here in the script section, uh you will see, show message and, for example, datum editor in this case. I'm going to execute this one and basically showing the message right. So you can make your scripts. You can put them in actions and put them in any place on the screen.

B

Basically, and let's see the I have some scripts property editor, for example, if you have seen the example, I think the example is actually here now I don't. I need to fix this layout, so let me fix it like really quick and then I need um well. I need just that.

B

So here is the link for the example, like the official developer example on how you should get the I mean how you can modify the settings for a property editor, so basically, I'm doing the same, I'm getting a property editor and for the I'm getting the property for the person object in the detail view and basically, I'm replacing the control to have a different value in general.

B

So let's go and check another one. I have the string properties or change, so you can interact with any part of the of the of the property or caption value or control settings in general. And let's see what else do we have here and also that's a quick, quick question.

C

From the chat from fernando asks, I just hosted the script. Does the script have support for try catch a logical exception? If then case yeah for your basic.

B

Logic, actually, if you want, I mean most of the stuff- are supported, but those are not created by me. So if you go to github genes, you will see the implementation of the language like how many features are already implemented. I mean, if you go also to the guitar chart of this um project. It's huge. It's a lot of people, making contributions to it or asking stuff about it.

B

So most of the stuff you can handle- and you have some really neat features- I have not exposed them yet to stuff, but for example, you have, let's see, let's go down a little bit, you have constraints. I think this is really important when you're doing scripting, for example, you can tell it there is a memory limit. I don't want this script to use more memory than this, so in that case you can protect your system from some people writing, maybe bad scripts or bad intent. I mean do it uh something with um being evil.

B

Somehow, like hey, I want to break the system, so I want to do. I will write a script that will loop all the time and take a lot of memory, so you can set a limit of memory here. Also you can set a time interval. I don't want this script to run longer than this time, giving like 10 minutes. If is 10 minutes long, it's maybe is hang up, so you can kill that process, so you can set some limits there.

B

All of this you can set that in code at the moment, but uh there's no ui for it, but I want to expose the ui, because I think that each script should have a set of options. I don't want this to use more than this memory or to run longer than this in general, and also you have all these possibilities with the net interoperability and what is needed, but I don't have an example here is that you can also include javascript libraries in your codes, so you can mix and match javascript and net.

B

At the same time, maybe you have a regex, regular expression, javascript library, that you like a lot that you've been using for so long, so you can include it here. Maybe the net doesn't work like that, but you can execute that javascript actually from here. So basically, what you're seeing here in the scripts are this. What you can write here is the mix of dot net and javascript in the end, so whatever flavor is best for you.

B

Maybe you have a lot of libraries in javascript that you want to include- or maybe you just want to make some dynamic code in the net here is the place to do it, and we were talking about this with dennis that I'm the person who loved the state machine module, so you can also make scripts for the state machine, so, for example, oh, this is also with wrong layout. So let me put this here and make this bigger.

B

So, for example, here where I don't have any state machine created, I think you can select the state machine. Then you can select the state and the transition that you want to listen to. So when that transition happened, then you execute some code there. So well, you should ask dennis about it, because at the moment I'm using the rich text editor- and I want to I was- I was doing some experiment with with monaco editor, which is the one that is used by by visual studio code.

B

But the thing is that all of these are experiments and they take a lot of time to figure them out. So if anyone want to collaborate with, maybe maybe.

C

We can get to that later, but I don't have a demo for for vs code, but I I have a quite a strong idea about uh monaco because I worked at drama so.

C

The question was: uh uh why do you support intellisense in the the code editor? I think the the answer is.

B

When it's implemented yeah to tell you the truth, um I'm looking forward for the intellisense, because I use it a lot I mean, and everyone uses a lot in general, but the thing is that there are some things that I really really really like about the let's see.

B

Just, let me close all of this and let's go to the normal script. um Let me take this script, so let's see view why I don't see the oh yeah. There is something that I like. I like this better than the intellisense feature like, for example. If I let's see, maybe it will not work at the moment, but uh you can highlight the stuff. You cannot do this in visual studio in normal visual studio, so you can write like or also you can change. Fonts like hey like this is a comment right.

B

This will not execute, but you can make that comment like really big if you want. I wish that visual studio can have something like this like more like a word editor that you can change, colors and everything for you, because that will help you to figure out some stuff. You can have some visual cues about hey.

B

I need to work on this like, for example, I can make like uh jose, don't forget about this and what not fall so and then you can make it red if you want, so you will not forget about it, see you have like a big stuff there and also yes,.

B

And the funny thing is that this will execute. Anyway, I mean it doesn't matter which format you put on the text, I'm getting out, I'm extracting the text and executing just the text in the end, but you can do any reach format that you want. That is something that I really really really like. Actually so,.

C

Subtitles a quick uh uh comment on it code rush have that feature, and I think you can even add images. uh I think you can even add images in in that too. No, but yeah.

C

It's a rich text, editor editor. It has all the features from uh the rtf editor. um The thing is like um you have to think or about when, when you use that uh scripting feature.

C

What are the goals? uh uh I totally get it it's. It's a really really really cool feature uh to implement in in in a larger system where you don't have to redeploy all the stuff and you have to make adjustments and and and modifications to the system uh and the model editor itself exactly easy.

C

Isn't enough uh for the commenting feature and and and and and getting into mamacot, for example, uh getting intellisense to work. All the kind of stuff is a hard road, uh but I really really really get the feature. It's really really cool.

B

um Yeah, basically, because you can interact with a lot of parts from stuff that.

D

Is that you don't need.

B

To recompile, so it depends. If you have a soft application with just one screen, you will not include the script eight or for that, but if you have some type of an erp type of system, maybe you want to do an escape. Okay like when this invoice changes status to this from this script, send an email or something.

D

B

So that you can do it's not a lot of code because don't write your whole application in the script. Please yeah.

D

B

Those stops that you can change like. I can really give you a hand, and also this is the.

C

One one question: one question from that's for me: uh for now: uh scripts are stored in in a database, yeah, okay, and um is there any kind of cycle where you get uh scripts out of the database and then for get it back into the release cycle? Or is it.

B

Just I wanted to have something like you extract them, so you can run them from visual studio or something like that. So you can have the void and stop other stuff. But basically I have the idea of how to implement that, how to attach this script to a process and then do the booking. But again this takes a lot of time and you have normal work in general. So there are some.

C

B

C

Just for me, so I can understand it. It's like you, have your xcf solution, uh your product, your aap systems, stuff, like your xf solution, and you have a customer or some customers that need more customization, that the model editor provides. So you need to write some kind of modifications, but they are so small.

B

You just it's not worth it to recompile in that sense. Yes, because this is basically uh we were talking about that with javier, and he told me well that is nice if you're a really technical person, but this is an overkill for the normal user. I mean sometimes like some, some even small screens are complicated for them. Can you imagine like hey? You can write the script for everything and well.

C

The question: why not see sharp scripts? I think I can answer that question as well. uh The the main problem is c sharp, isn't a scripting language at all, and it's it's hard. There are dialects. There is like uh there's cake out there. There's scripture.

C

There are a lot of of of options out there, but it's really really hard to get into. um First of all, it's hard to to uh um scripting is easier in javascript than in in in a strongly typed language, and the second thing is: uh there is no clear dialect from microsoft.

C

Let's do vbscript says gp. uh Yes, uh if we do vbscript, we can uh go and uh go 20 years back and do extra scripting again.

C

The thing is, I I think javascript is a great uh scripting language for that purpose. Yeah c-sharp is, is really really hard to script um because it isn't officially scripted.

B

Yeah and also manuel there is uh some stuff regarding the references that you need to check and the compilation pro is not interpreted. You have to compile it and then include it in your application with the application domain, so the uh the first I mean the first version in ultra of the scripting module.

B

You were writing c sharp or visual basic, but it was harder to maintain because you need to compile that. Make sure that you have all the references, create a project in memory and then include that in your application domain yeah, so that, even though that is the that was the first idea, um I thought that maybe you don't need to include other references. You don't need to include some like it's like.

B

Let's work within your application context in the end, so it's like whatever you need for your application, you should include it in in the executable and with the script. You can uh basically execute all of that. So in the opposite case, in the original version, where I was using visual basic and c-sharp in general, it's like okay, you have this part to include nougats if you want to download. So it was way more complicated, just all the setup.

B

So when I found gene- and I did some tests actually started with in blazer actually because here I have the first script in the screen, so you can create a script template and then you can create the scripts like this and in the end uh you can pick the language c, sharp or bbnet.

B

Then here you have the script code, and here you I don't have intellisense or anything, and then you get the compilation result that will produce an in memory assembly and you can save it here, so you can execute it and next time you start your application.

B

This, the assemblies that are in all the scripts will be included in the application domain. So there will.

D

B

Available compiled for you, but this doesn't make that much sense, because if you want to do that, you just make a plugin framework where you can load assemblies. You don't need to write that assembly here. So I think that is. There are two different purposes.

B

If you want to include compile assemblies that will be for me a plugin framework that is something different than the scripting framework in the end, so I have the two flavors and with all of this it's hard to know how to continue you create them at the beginning, for maybe a small set of uh requirements that you have and then usually you go crazy. You like it so much that you start writing more code and records.

B

You need to know where to stop and when someone is going to use something like this, because maybe someone everyone likes it, but no one will use it in the end. So so you need to make sure that you're not wasting your time with this, but it looks like everyone likes the script in gene machine, so.

B

C

About the scripting thing is scripting is like uh for for me as a professional developer. It's like it's the it's, the um there's, always the the boundary where scripting makes sense and- uh and there is- and I know c, sharp and and and all the languages for example, uh uh microsoft did it with with windows, uh not microsoft.

C

What's it called the playbook style of thing like.

C

Python does it, for example, for machine learning and all that kind of stuff, but that's a small area. That's like like that's not for application development. It's like testing out stuff, it's like a better console application and for normal application development.

C

You have to uh get into the boundaries of how do I deploy that test that kind of stuff? But I think that's a really really great example how you can leverage um uh javascript in combination with, with csharp and and and and and enterprise.

B

uh Actually, one of the usages that I gave to this is that I do a lot of machine learning prototypes. So sometimes I just open the staff application. I include the module and then I write the machine learning code on top of that as a script. So, if you're doing machine learning, then I think it's there is a lot of value here and well.

B

Since I see a lot of interest, I will publish some more articles in the in the facebook group because I I think it's a really neat idea and if you want to collaborate with them on equator, because I've been playing around with it, but it takes time to understand it and how it works. So if you want to give me a hand with that manuel uh you're welcome to do it.

D

B

That's everything from my side so today we're going to move like to the next uh community module, so those are the ones from yamachan. So I will stop sharing my screen and dave uh when you're ready, you can start sharing.

D

Perfect, although my zoom window just.

B

Yeah, it happened. We.

D

B

Conversation before the meeting that sometimes would you use this zoom your days just go gone.

D

Yeah, no it's! uh It is actually a 10 foot by 10 foot, two story: high little bunky thing so yeah, it's cool keeps me away from the from the family making noise. So it's great good. uh Can everybody see my screen? Yes, visual, studio, perfect, okay, so yeah we have the llama champ framework modules. These are uh free, download news. um We created these because in every project we were putting together, we were always doing the same collection of things, so we kept duplicating the controllers.

D

So we said you know what let's take those and just put them into our modules.

D

A lot of them are samples that came from devexpress directly that we just tweaked- and um you know, made usable for our own, but we use this in pretty well every project that we create.

D

uh You can get to that from our website. Limitchat.Com right here on the the main page or up under resources.

D

There's a few pieces here that are are useful, including our code, snippets uh framework module, a video, a security preview, module that you'll actually see today as well, and our controller management module, which we talked about a few sessions back to. Basically, deactivate and try to identify bad controllers, so in the llama chat framework module. The last update was the end of 2019. We haven't touched this in in forever. It just works. What we need!

D

uh We asked if you use these by all means. Let us know we like knowing how people will use our modules. uh Please do not resell our modules as a product. You can put them in your products and sell those. That's fine. Just don't sell our module on its own, um so yeah. We both basically focus on win and web. uh Some items are, you know, win and web. Some are win only some!

D

Oh, we don't have any other web only, but you can go through go through these and see what the basic features are. These are not really well documented. um I'd love to have somebody come and document these. For me in a bit more detail, like I said, we've we've been using them so I'll just give you a quick run through today as to how these work.

D

uh So at the bottom I click download. I grab the actual uh project files include them in my project.

D

Add my references and so on and so forth, and so what I end up with is this structure here, where I have my my you know my xf application uh when in web and then my modules in here, okay, what's really kind of cool about the about these modules- is that when I run these after including them, they don't really do anything.

D

They just sit there passively until you turn the options on and off so you're, not you're, not going to experience really strange things just by adding our modules so everything's in here I can see it. I can open up like my business objects, everything looks fairly normal.

D

um You know I go into come on now, right, I go into my different views, everything it's a it's a standard, look and feel nothing's changed.

D

When I go into the model file, do it I'll do it at runtime? But of course it's off the screen again there we go uh when you go to go to the model file, there's a section under options which are the lamicham framework, and so we have a bunch of uh just quickly turn on and off options, so deleting non-aggregated objects.

D

What we find is we flip back to this so many times when you create a menu to many collection, there's no aggregation whatsoever.

D

You end up with things like involved teams where you can link and unlink uh from different teams right so from different objects and 100 of our users will go in here and say: oh, I don't want this one in here anymore, delete they think they're removing it from the the collection on this object. They think they're going to remove this. You know the reporting team from my project but in reality they're deleting the reporting team.

D

So the first option we give them is the ability to remove that everywhere. Say: hey you're not allowed to remove those objects.

D

So what happens is when I go back into my projects? To that, many to many that delete is gone. I say: link unlink click, new! Take my pick when I go into the actual detail view again off the screen, then I can go and delete it. So it's just an extra step to protect users from doing stupid things.

D

So we come across that all the time I'm going to turn a bunch of these options on next. So.

D

um So the allow font size selection again. This is uh windows only turn that to true allow summary panel uh menu item turn that on uh bold tabs with counts, so this is actually bolding tabs that have items inside of it. uh We used to combine this with the show, counts and tabs. uh We split them out, but we kept the the naming the same I'll. Do that, for both the show type name and open object, something we've seen in the uh the open object.

D

Actions doesn't show what you're going to be opening depending what you have selected and then we have some audit trail specific stuff. So can you restore from not a trail?

D

This is uh I call this experimental, but in reality it works quite well as long as you have the full audit trail on and who can view the audit trail and the options here for both of these are either all everybody can can view or store from our trail or you can make it user specific, so I'll make these user specific I'll, save it now we'll get out of here and we'll see kind of. What's going on so right away, you can see my my tabs here are bold with a count inside of them.

D

This is handy when you have nested tabs. If I had a collection of you know five ten tabs uh do they have notes, do they have collections of items you can go and you can go and find that, just by seeing the number by seeing the fact that it's bold.

D

All right same thing: here we put in the uh the font size option. So, under the view we have this font size and I can pick yeah. I want to go extra large, so people who are visually impaired or people who have high dpi monitors, but your application is not set to handle high dpi. This is a great option and you can actually determine what sizes you want as part of that model. Let me put back in here again under the options we have these font sizes.

D

You can add your own collection here, whatever you want to call them change the sizes and away you go.

D

Alrighty, looking at the audit trail side of things, this is kind of neat. So under the tools I normally have an audit trail available here, but because my user doesn't have, I made it user specific, my user, which I've called an employee in this case, doesn't have rights to view or or restore from the audit trail, so I'll just check both of those off and I should have to log out actually, of course, I've done the active directory authentication. So there's no log out.

D

Coffee back in here and now under the tools, I should have my at my view, audit trail. So I can click into here. It brings up my list and I can see you know what's changed when.

D

D

The restore from audit trail is kind of cool, so, um if you're familiar with deleting objects in xaf with deferred deletion and really only when you have deferred deletion on the related aggregate objects become disconnected so in the database you know. Typically, a contact will have a a company, id or client id that relates back to this parent object. So when you delete it destroys that relationship for a good reason, so I'm gonna go ahead and do that.

D

Okay. So now on my client list, I have no clients, so I can go back into my tools and I can, I can actually say, restore data. Of course we say it's experimental.

D

We say that because we don't know how your objects work, so I don't rely on this 100 but, like I said in most cases it works very, very well, and so I can actually go in here and search for items that uh that I delete within a specific range, and we do this because the audit trail tables can get extremely heavy, but I can see here now. These are all the things that I deleted when I deleted my client.

D

So if I want to bring my client back, I can actually do a preview to show me what's going to be restored, that's saying: hey, I'm going to restore all of these items.

D

Okay, so I'll go ahead and pick that one I'll say: restore I'll, go back to my client list and refresh and there's my client back. All the relationships are back in place. My project, my project, has all of its links again, including the many to many's. So it's a really nice way. If somebody screws up and deletes the wrong thing, you don't have to try to reassemble it. You just use the the one-click.

D

To say I against that: that's that's a really, really really neat tool. We spent hours restoring stuff from audit trails in the past, people have backups and you're just like what changed um so just having the one-click tool to do it is, is so much easier yeah once we put toolbar options in so you can. You can hide toolbars and show toolbars.

D

That kind of thing we've put this show summary panel in here, so that just puts the option at the bottom. So you can do your your aggregates, your your accounts, your mini max your average, all that jazz just the click of a button. So it's just convenience.

D

uh If I hide the toolbar, I have the option to show the toolbar again. It's quick and easy that works on the web as well.

D

uh In the background, there's some kind of cool things that happen that make um development of your objects a little bit easier. So we'll go, have a look at that.

D

So pretty well, every application we create. We like to do a little lightweight auditing, to show who created an object who modified it last and if somebody deleted it, who do we go and blame uh so we create a custom base, object, and so in here you'll see I have this. You know it comes from my typical base object. You can make that for whatever persistent base you want, but we do a you know created on created by modified on modified by deleted on deleted by and to make the process of tracking this easier.

D

We've built. This tracked object helper, where we call the outro construction, you can pass in the name of a created by field and if it's a user, we'll we'll basically assign the current user to it, and that happens for your after construction you're on saving and on deleting the reason we put it in attract object. Helper I mean you could put this into these methods directly, but when you have a situation like in security, when you've extended employee with the permission policy user, you can't then inherit from a second a second object.

D

It doesn't work, so we put this eye tracked object interface on our custom base object. I can do the exact same thing in my employee. I haven't done it here, but I can do the exact same thing and I'm adding basically those fields and those three lines of code to replicate the same functionality, to keep consistency across the entire application.

D

uh What else? Oh, we have an option for.

D

I'll go to the security preview after let's look at the options, so in pretty well again, every application we create. We have one options table and what typically happens is that people have a list of you know, have a list of those options and somehow they'll create a second version of it, and then you don't know which one to load.

D

So we create this. I singleton bo interface. If it has it it's a bit of a bit of a nasty uh implementation. To be honest, it's uh it expects you're going to have this get instance method here, but because it's static we can't actually enforce it in the interface.

D

But basically when I go to program options in the uh in the navigation, even though the navigation item is set to be the program options list view, it's automatically gonna intercept that and show you the the detail view instead, so you're only ever going to have one instance of that object.

D

So just by adding that uh you know you add the the one or two methods the same thing and adding this interface. It just takes care of that, for you really quick and easy.

D

uh The last thing I want to jump in on is the uh security preview, so actually in our it's not part of our our framework, but it is something we do up in the security preview module. So there's a little bit of a video on how this works.

D

Basically, there's one controller that manages the switching back and forth of security, and what I like to do is put a an option on my employee class or my user class. That says you know: can they do a security preview and in most cases, I'll make this browsable false? So you have to set it in the database directly. So you just can't just go and say yeah I can preview security, but basically what happens is as I'm working on. uh You know, working on my security roles, so I have employee role here.

D

I have two roles right now and in this role I'm saying hey: you're not allowed to see uh and the employees the employee roles of the the project uh teams over here and type permissions. I turn a few things off great. uh I can then go to the tools, say, preview, security and say I want to flip to the basic user logs me out logs me back in and now I'm in as a user.

D

So I can go in and be like. Oh yeah, I can't see that that's right. What if I go into project, can I actually edit projects? Can I see the project teams? Can I create a new? Oh, I can create a new team still right, so I can flip back and forth very quickly back to an administrator. Go back and change my role again flip back, and I can do all that over and over for every single type that I'm working with it's a really quick way to create to create roles.

D

If I create a new one here, this will be a read. Only user.

D

Read only by default when I go to my tools, it's not going to be here because it's uh it's new I'll refresh this now I can go back to my read-only user. Here I go so this is a really convenient way to go back and and just test those roles out.

D

Any questions any anything come up in the chat I haven't looked in the chat in a.

B

While so so far so good dave, I think there is no questions at the moment, but the presentation is great. I actually, I love this feature of one.

E

Being able to switch on one jury station component to have a super foreblazer, because only website.

D

It's only yeah, it's only web zap right now and it's a limited subset of those features. um So let me go into the web module real, quick.

D

It's a weird uh visual studio, bug with refreshing when you're presenting. Strangely enough, uh so I go to my options so on the website. You know I can do the oh. Where are you.

D

Web, did I add the module.

D

Same deal come back here, nope.

D

D

Let me go ahead and rebuild that. I should close that there rebuilding build, succeeded, close that down we'll go back in here.

D

Now there we go up here so again the uh the non-aggregates returning delete to that off uh bolds we can put in the audit trail. It can be viewed and then the show counts.

D

So things like the toolbar, I think that's already an option out of the box. uh Whoops I'm up thing.

D

Here yeah: it's not uh it's not set up for blaze yet, but we haven't touched this since the end of 2019, um as we start getting more into blazer projects, we're we're working on a couple right now, but as we start getting more and more and as we see more emerge from devexpress as well, uh we will readjust you know, and these modules make them working in blazer.

C

uh There was one question: are they are there modules added to my app or do you need to inherit from app from one you defined? So do you need a base class like uh llama charmed, um uh uh uh uh module or llama challenge, so yeah.

D

There, I know, with uh things like expand framework there for a while, at least there was a need to inherit from that application type. uh In this case no you're just dragging the modules in like you would any one of the other, the other modules it's really straightforward.

D

Oh I'm still in the wrong user administrator. Here we go.

D

There's my tabs and there's the uh there's, no delete button right, so those are the things that just kind of help out along the way. It's.

C

D

Until you turn things on, if you you know, if you don't want, uh if a user hates the idea of having uh the numbers in there, you know for that individual user go into the model and turn it off problem solved so yeah. That is it.

B

For me, uh thank you dave. I mean, I think the presentation was great. uh I see some features that I've never seen before, like, for example, to restore uh deleted objects and how you handle that it is amazing. I think it's a good thing to have, especially if you handle really well the audit trail, because you know that the audit can go incredibly large, really really fast right. So as long as you handle that, then your module is like amazing in that sense, and also the the security preview.

B

That helps a lot um because, like a lot of people, ask you for a lot of roles and they don't know how they will work, so you have to test them for them, and this is a really easy way to show that hey, you do a role like this and then you can go and look how it will work in general. So uh I think that those modules are amazing, you're, getting some congratulations in the in the chat. So thanks for it and right now, the next presentation is the very own manuel uh with senile.

B

So manuel is your time to shine.

B

So the screen is all yours, uh then I will just close.

C

The chat, yeah uh and share my screen: will you share from this.

B

Computer or from your other instance no.

C

From my other instance, okay, um you can see my nice little tent, yes, yeah, yeah, yes, okay, um just a little um and and almost everybody saw this presentation I will. I will do it really really really really really quick. That presentation is about a year old and uh it's more the journey of going um what it takes it takes to to uh uh do this as a living and and getting stuff out and and and and trying to help people.

C

I did a lot of consulting in the last one and a half years like llama champ, for example, that did um and and jose, and it's really really really hard to get a product out there and I'm a single person. So I have no employees right now. So it's it's really really tough uh journey to get into um that kind of stuff, and I learned a lot doing doing that.

C

But um the goal of samuel is is basically everything I learned in the last 10 years of writing application um for external customers and doing a lot of consulting. So um the slogan is like here: okay example: it's easy! It's flexible, it's focused.

C

It should be adapted to all your needs, but uh it is hard to to get into this point, so I don't want to make too much marketing uh flaw schools, it's more like uh what do you need to get the job done and what are the really really uh what matters when people write application software, especially in in in those niche markets, and it's hard because uh they, um you have friends from from business perspective, from from small shops, to large space labs shops with all kinds of problems and.

C

Sometimes soft the the framework uh feels like it. It's getting into your way and uh I worked with really really small shops and they were really really happy with xf and the larger xf grows the harder it gets to manage, with a large, larger set of team members and and and scale it up and and sometimes or most of the times when stuff starts to grow.

C

I had the problem that it's hard to get together with with the model editor. For example, you have merge conflicts, all the kind of stuff except gotta, get way better in the last uh couple of years, but there's still a possible improvement and there was the idea of cenial born it took a long time to implement that strategies and make them available to uh other uh developers.

C

um Okay, we have what what does signal mean? It's a it's. It's a hospitality kind of thing, we're no zero, so uh we like to be hostible and- and we like to to help other people, um but for me it's like get the job done and don't get in my way, it's like uh leading the developer and all the team into the right direction.

C

Okay, um so that's the slogan: it's it's easy, it's flexible and it's focused. So uh it's you! You can expect that samuel won't get into your way, not now and not in the future. It just tries to help you as much as possible and don't get in your way so um that that presentation was two years ago or one one and a half years ago, so my slide stopped there. So, let's see how uh that actually can look like for today um and.

C

You can go to.

C

Sorry, I'm not that well prepared today, one two.

C

Can I okay, I can move that down the screen. Okay,.

C

C

Okay, so um it's not live right now, not yet 100. I wanted to to get it done until today, but I didn't, but that's that that's the way life goes uh with our pricing website and it's not about the pricing and all the other kind of stuff. uh It's you can inform your on sale once I.

C

Once I'm done, I will tweet it. I will send it to you guys, but that's that's my last the the project about the last couple of months. I guess so um you can look at some of the features, there's a lot of text that will be replaced and I will go into some of them into more details. There's like the model builders there's like a metadata framework based on the xf excellent uh uh metadata uh stuff.

C

That's really really handy a lot of stuff under the hood you saw before uses this a lot. I guess um there are is like a flutter syntax for layouts as well for uh list views and columns and and they get all together. So it's getting easier to write, really really platforming agnostic uis, uh and there is a lot of qualitative uh melancholis improvements on top of xaf. That just makes the coding easier, like glamour, chart exam extensions, there's a lot of stuff that we have in similar.

C

We sometimes uh solve a little uh stuff, a little bit different like the uh signaling stuff and um but the main thing is sometimes xf feels a little bit clunky. If you uh work on a team and you have a direction and it's you have to go into a flow with with your team and try to really make a difference in in the quality of your product.

C

Another topic is there's a lot of editors uh on the way, and there is one editor I want to um there's it's currently on the on in the lab phase. Is the webview 2 editor, based on the microsoft of the new microsoft um edge browser, so it's easier to integrate web content?

C

So, for example, with uh uh what jose told earlier, there's a lot of stuff, we can do in the future to support, for example, stuff, like um uh um monaco, monaco yeah. Thank you and there are a lot of ux extensions.

C

uh I did over the past couple of years, so when we go to my blog, for example, I'm blogging for a very very long time and for example, there was the blue, uh it was if it was a 13.3 like the windows, integration module, that's really really hard to do in xcf uh and do it on the on the right step and getting those user experience capabilities into an xaf application.

C

So um that's the main focus about samuel, doing your stuff. You have that idea and getting into the right direction without that stuff having to getting into your way. So that's all for uh the um uh for the advertisement, but it's a single ma, a thing. I want to uh showcase real, quick, it's like uh where the road is going. So it's not sleeping, even if I didn't release it yet, there's a lot of stuff that is in my head, going around and uh helping other customers and and getting it on the road.

C

So uh there's one really really important question that that a lot of people ask me is like: uh will you support ex samuel for web forms, so the classical uh xaf win web and the answer is no.

C

I am going to be the first one in the world that supports wind forms and blazer.

C

So I I think in the in the first direction and in the first row to support you guys on getting the best user experience out for the new way for getting into the blazer way of doing things, helping you transition into the next century or the next net kind of phase.

C

So I really really try to um help you and uh have both platforms uh in parallel, so we had a little in the last 10 years. uh Winforms and web forms was like kinder comparison, equal and I tried to do the same thing with blazer and winforms.

C

Why wind farms, wind farms, won't die, not quickly, it will not die. It is a great platform, it's a it's a great opportunity and it it it just works for all that kind of business applications. Hundreds of thousands of people rely on and blazer, on the other hand, is like the smaller brother that can really get momentum if we want to support blazer uh mobile phones, tablets, web stuff and so on and so forth.

D

Okay, sorry, do you have uh documentation for all of this, and if so, can you post that.

C

Yeah, the the thing is: okay, we have like. uh uh uh We have right now uh feature center, sending the framework.oh. I will post it real quick in the chat uh it is. It is an interactive documentation.

C

If I find my chat where it is no.

C

Jose, can you help me out and post my uh link on the chat? If I don't find the chat window.

B

Okay, I will look for the link and post it in the chat.

C

There it is, I have it on my on the other screen so uh that that's that's just that. That's a feature, something that's designed to be a living documentation and it's built upon all kind of stuff. It is not complete because uh I focus on the editors first, because I think they are more the most valuable, but you also can download the reference demo, and I will do that right now.

C

So it's taking a couple seconds.

C

C

Show it in folder.

C

I have prepared it, but of course I haven't prepared it. So I'm just.

C

Extracted here, real.

C

C

Okay, so um let's do a little quick comparison between the blazer feature center, so you for some times are not some editors or some stuff isn't supported, because devexpress doesn't support it yet, but some stuff is uh is designed to be just equally: uh uh it's played from an agnostic, so it doesn't matter where you run it, and if we have a quick comparison between blazer and uh and the editors it besides. The step focus editors that aren't supported are using the native devexpress controls, but those are only the visual components.

C

So I hope you get the point there where uh I'm trying to maneuver with the new stuff from the editor's perspective. But now, let's we have the model builders and the layout builders and those are the most uh uh interesting parts of the whole whole stuff, because everybody can write on an editor and do the kind of stuff. Okay.

C

We have the batches like the alpha here and the lab stuff, um uh and here so it is supported, but those are visual clues to the user, but it's really really hard to implement sometimes that kind of stuff in an xf application. So you don't have to matter about that, show a note notification for a new mail or for a new sale or for new.

C

That's that's the that's the better stuff you can do whatever you want. In that perspective, uh if I find my mouse back, uh we can look a little bit about the code about the model. Editors and the model. Editors are really really the uh neat thing. ah Moderators uh the model.

C

Group how's, it called model builders. So it's it's! It's like a um it's a it's a way to describe your um uh the metadata for your xf object or your business objects or your domain objects e code.

C

So the neat thing about doing this is you can use constants you can use. um If then else, statements and stuff like this, can you guys read that or is it so small.

B

It's good, but I think it's.

C

B

C

The thing is: um normally: you have like 10 20, 30, 50 uh attributes on your business classes and that's fine. Sometimes it's really really good to have everything in your in one place and sometimes it's not, and if your team grows and your application complexity grows, uh it can be a really really reliever to have something you can control in code.

C

um The thing is we're looking right now at that feature center. So we are looking at that code right here, and that is exactly the demo. So I'm looking at the model builder file, uh it's a naming convention that I just called it batches introduction demo model builder, dot cs, but it's just a class that derives from model builder, for example, that is type of batches that introduction demo. What is basically, this kind of um uh this business object.

C

And those attributes normally are described as a caption attribute image name, attribute, default class, edge options attribute, and now we have two additional methods. We call that add another attributes to the type system.

C

Basically, the xaf type system works like okay, we analyze all your code and then we collect all the attributes together, all the information, all the types of system, all properties, all methods, and we collect them all together, and then we can add and remove attributes at runtime, and that also means we can do a lot of stuff with uh adding and removing attributes at runtime.

C

So we maybe we want to change that text. That's a bad example, but we want to change the text for a customer name, for example, so we have a if that customer is x or is y, for example, it's a little bit hard to describe here. I will get into this in a little bit detail, but, for example, uh you also can apply that not only to the class. All of that stuff is at class level.

C

uh We also can do that at property level. So let me show real quick. uh I have a mail client right here and this is a really a male client with my real emails. So I hope hope I don't preach anything.

B

So manuel in the meantime, when you're loading that so that means that you can have a class without any decoration and you can implement.

D

It in a different way.

B

In two applications, because you do the decorations in runtime in general, exactly exactly it doesn't have to be in the.

C

Same assembly- and you don't even have to load xaf in the uh you, don't have to use the xf uh yeah.

B

C

B

Sometimes we do a concept.

C

B

A lot of summary and application: well, a big part of business is summary and application, so sometimes, for example,.

D

The decorations.

B

From from south into the same application, so I just wanted to keep it for safe, so I usually use reflection to include our attitudes, but it's a little bit cumbersome, because I want my models to be just models without any decoration, so I can implement in a different way in maybe the same application or in different applications right. So I think this is a really neat approach, because you leave your model as model. Actually, no, no.

B

The thing is, there are.

C

Some restrictions, for example, uh but maybe we can work out with the with the xf team- it's like that. The main component attribute is a good example. Sometimes they respect it and sometimes they don't, but most of the time uh it's it's working like in entity framework.

C

If anybody works with entity framework, you can alter your metadata all the time, but this is not for the tables and infrastructure and the relationships. This is about the whole xaf infrastructure.

C

So uh if you look here in my uh in my demo right here, it's it's my real email and this is describing more or less my. uh uh This is like a male. uh The main list view, so it's a male uh model builder and it's like stayed from blah, and we have all that kind of stuff and there's a lot of stuff here and it isn't uh working. I I I can't change anything, but if you look at my mail class, it is really really just the xpo data.

C

Okay, I have included the rules for for the validation module. uh There is a validation module coming for the model builder later. I have that in place for many many years, but it didn't make the cut for today, but everything else is just xpl code. So there's nothing xf specific here besides that action, so that's xpo only nothing, no attributes, there's no! No! No! No! No!

C

There are no special navigation item attributes something like this. It's just the main class, and now I have to make.

E

Setting the pores and the authentication model.

C

uh Four, I I I I I didn't. I didn't uh get a question. What was that? What was the question? uh What is about security and identification.

C

I I can't hear you your music, muted.

B

uh Fernando you're on mute, so if you want to do the question you can ask or you can write it on the chat.

E

B

E

Business class um you're selling the port at the port for um port number; four number incoming and open number: four: oh and input example uh 110, 587 for and modern authentication.

E

B

Fernando, if you want you can send me the quest, a direct message on spanish, and I will put the the question for everyone here in the in the in the conference.

E

B

E

The field, what is the field for setting the port and the authentication model settings for for communication.

C

uh That that's that's, for example, that's a direct database communication. That's that that doesn't that that's not related. If that gets a question.

B

I think that uh fernando means, like he's asking about the smtp class like for the mail client in general, so I I I am.

C

For okay, that is part of my presentation, but I am using mail kit at my kit and it's just using standard open source drivers for that kind.

B

C

Great yeah, so if you, if you have questions about that, let me leave me a message or an email, but it's it's it's about that uh model! Builders right now! So, okay, that that's that's just a neat thing! Okay, we can uh do. We can do that in code. We also can get- and I did that before uh we can get that from another database. For example like for my configuration database or stuff stuff like this, so uh we are in code, so we are not uh in we.

C

We are in the uh need to do that as a constant, and we don't have to do the hiccup and okay. We need to change that or change it all that uh we can just read it here and do like uh mail, mail plus. Okay, uh let's do change our caption from mail to mail uh plus random.

C

I know we don't do random, but uh and don't do plus, but the random next bytes. Okay, let's stop real quick.

C

No, that's a system math random.

C

No, where is random.

C

Random there it is uh new random next uh yeah, let's take 0 and 100 just to show the case.

B

So we can do anything we want in code manuel. I I have a question is that if I'm not using xp or well, I'm using xp all the time, but let's say that you have a different library, so this approach will work for anything that is net or it's a special case for saf and xpo. It's.

C

A special case for self, if you use it with stuff, I will show it: uh it's not xa xpo only it works with any soft project, but it is soft only.

C

But if you can see here now, it's mainly 75. yeah, okay. So uh basically we changed that to a random number, but we have to restart the application or at least to reread the metadata, and that is a critical part.

C

Besides uh all the kind of stuff that's inside of xcf, because it's reading your metadata and then it generates the model layer after that, so I still can do edit model.

C

And if my model editor goes up onto the right window, you can see it didn't uh change anything.

B

About about the mobile cloud, so it's actually not updating the model. It's just changing the value in runtime. It's.

C

Before it's before, no it's before so every stuff you do is like uh we are that stuff we put into the model editor or in the model builder, it's like before even model gets generated and that's the idea.

C

So I can still go here and say: mail mail, if I can type main with model builders, are awesome if I can type, but I can't so it's fine so but it still works and it you get every benefit you have from xcf, but you have one additional layer where you can inject code, okay, so, but that would be kinda lame, but you also can do like conventional stuff and that's really really. I think the really really neat thing uh in my demo: uh not no fields, are editable by default.

B

So you want to change it to to make it editable, like just in this case, like with the model builder.

C

Yeah for this one one, one really really really big thing. There is example right here and I will open it with an xml editor and it's empty.

C

There is no model at all. In my whole application, no model editor nothing. So I am going to do all that kind of stuff in code and everything is purely defined by conventions and attributes. So and nothing of these classes are editable.

C

There's no security in place, there's no, nothing in in general. It's just there's! There's a convention here I can say for properties.

C

Not allowing edit, as I did if I right here so I'm applying an attribute to every every single class, uh every member of that class. So basically it's doing don't look at the at the code. There's a lot of stuff, but basically, basically what I'm doing is like for it for our properties.

C

B

Attributes and so maybe you should stop it- uh to get a better autocomplete and intellisense yeah.

C

So uh for all properties, I'm going to apply the model default. New model default model default attribute.

C

And I think it's allow edit force.

C

Okay, so let's run that again, so you can think about it that you're iterating over all of the properties and adding that attribute.

B

To every single line of code, I really like that approach because I, like my models to stay clean, yeah because otherwise you're doing like I mean it's getting.

C

Still it's it's still.

B

There it's still doing the same.

C

Thing, but if I don't uh remove.

C

That it should be editable.

C

And it is okay, so basically, it's like it allows you to write your own dsl about your data types, but the really really neat thing is, if you combine it really with data types, for example, I have here that uh um uh that they're all about four properties of type and I'm applying a special attribute to a special, a display format attribute to all properties that have the type the time so.

B

uh That's exactly.

C

B

Really really deep, actually yeah, I mean so.

D

It's like that, it's.

B

Set all properties to do so and apply.

D

B

That is our time. Saver.

C

Any any idea right now.

C

What what's what's a date, formatter f.

C

I have no idea f. Small f. I guess this full time.

C

I have no idea so.

B

C

B

Have to google the form of the string yeah.

C

Yeah that that that's that's the only thing, I'm working right now to get the refactorings in here. So it's date time for nothing. But the neat thing is: I can show you a quick uh uh hint on this. You have the time there yeah here it is so, but the neat thing is you: don't have to do that all the time you don't have to remember that kind of stuff, because your application should be unique and and should be uniformed in in in most of the places.

C

Sometimes you have to split, but 90 or 95 or 99 of the time. Formatting should be the same, at least for dates and currencies and stuff like this. So I really quickly show you how to uh you can uh remove those, because this is designed to be uh to be extendable, so we can do like uh four or not that small four for the property. I need date message: state uh test, display, format, okay and you can see, there's a property builder of daytime mail, blah blah blah blah blah blah all that kind of stuff.

C

So don't be afraid about this. This huge number of uh of um there will be a lot of um uh guidance about doing that stuff. But basically, what we are doing is we're writing an extension method for fluent api right. That's basically, the fluent for the fluent api is.

C

And I am just copying pasting this.

C

And we're getting the t of t and we have the d of t and we can call it that has display. Time, has my date format with the a property builder of the property and there's all the light kind of stuff, and there is the display format, and we don't need that because we specified that earlier and now everything we have to do. Is we take the builder and return builder?

C

Dot has display format or any other attribute, so you can say has uh with attribute and they can deploy your own, but we go for, has display format. And now we say it's zero and we say mm. Oh, no. Why? Why why?

C

I think it's mmdd.

C

I guess and I'm just using this and now I need the.

C

Semicolon and now I can use that format everywhere, oh nice, so I have no floating strings. I have no constants and the neat thing it works for every and, as you can see, it is wrong because there is no yyyy.

B

But you get the point manuel one question: uh do you have the commentation for this part of cenial, because.

D

I think you will get yes so.

B

You will get some volunteers in the in the chat I mean, because everyone is loving this future. This feature- uh and I think that is really neat because I like to have separated yes, yes to actually implementation. So now, in the end you can like um you.

C

Will define multiple properties, and that's that that's the thing I I I that's the neat thing about model builders. There is documentation about um model builders uh and I just need to have to open a window that is opening on the right screen.

C

So, let's open a new window and go here, I blocked about this uh archive.

C

Model builders.

C

Here this all the technical details about how it's implemented. There isn't a definitive documentation about this right now, but you can go just to.

B

And why don't you share that uh link on the chat for everyone.

C

B

Have it sure sure.

C

Let me put that here: real, quick and put the other one as well. uh I would love to hear your feedback uh on samuel iowa extended framework. Everything is open source. You saw today right now and it's it is open source, it's not free, but it's open source, um but that's the best documentation. I have for the non-code samples so uh but the most part is uh um best documented in the demos.

C

How I use them and stuff like this, but just leave me an issue here. Ask questions.

C

Get I love to get feedback from you. Currently you can. The installation process is also documented on the um on the demo page. So there was framework the center dial, so framework center feature center, so it normally drives you step through straight step through every process. How to uh what you have to do like you normally have to do, but it's more code centric you can use it.

C

I have two or uh two or three users that are using it with a normal uh xf kind of way with designers and stuff, but I don't recommend it because I don't test it, uh but I'm just getting to one small little thing and this that's the model builders. uh Basically every feature is designed about. You can pick and choose uh what kind of feature you want to use in your inside your application.

C

You can go the normal route and should, okay just add the module and you're good to go and you get everything but as like dave's modules, it's like the minimal immersive feature that you can have because you have to opt in into it and everything is like designed about to be opt into it or you get everything or small features slices uh in between.

C

So um if you can uh look at the usage, for example, you can. This is the minimal, with the with the um with the model builder. With the attribute approach, like you would, for example, in a normal xf way, then you have the model builder stuff. That tells you how you can use it in code and you also have a gif that tells you how you would use that feature in a normal xaf way, how you are used to do it right now.

C

So you have all the flexibility between really really low code approach, like uh the model editor stuff or you get all the way down to other attributes or you may try out the model builder feature, so you have all the choice in between great and that that's the thing about samuel. You can pick and choose what what you like about the feature, what you don't like about the feature- and it's just the beginning, so that's all based around the model builder stuff and everything xaf provides and play up play around with it.

C

Let help and feedback. You can ask me all the time about this, I'm not 100 sure when it go to sale, but it won't be free, but it is. um If I can go back on my um on my pricing page, it's not online right now it is like normally priced. You have a a normal subscription license. You can pay on rolling if you're a company or an enterprise, and you need more support. You can go into very very.

C

I have to some very expensive uh deals, but the make the main difference between all the kind of additions is like what kind of better express support versions. Do I need to support the more they are getting the harder it gets.

C

That's why the enterprise version is so expensive because you can pick and choose for three or four years at that express license. I will support, but you can pick and choose and get individual components.

C

So if you don't need anything- and you just do want the model builder stuff- it's 10 bucks per month and you get all the components and we didn't even talk about.

B

uh The layout builders yeah one question manuel- is that for the runtime or for the design time what will happen with the runtime? Once I compile my application, yeah.

C

Very good question: you can do whatever you want with the runtime: it's just a developer seat license and you can. If you buy the license, it will be checked against the compiled date of daniel, so you can use it all the time, but for forever you like for hundreds of years into the future, but if I release a new version with new f express version support, then you have to renew the subscription.

B

C

Basically, license.

B

In the end, it's not it's not a subscription. It's a perpetual license. It's it's tight. No! It's! It's not really a perpetual.

C

B

That are supported for your, for your I mean if you.

C

Get one license today for one.

B

Year, all of those.

C

But if I release a new version next month, you don't get access to the new version and you don't get access to the new devexpress version.

C

So if you want to be on track with the dev express version, you can just buy a license and then unsubscribe and then, if you decide to uh buy up to the next step, express version. For example, you are right now on 20.

C

For example, and then you have like six months where you're working or eight months and then you decide okay. Now I want to switch to 20. uh 21. two, for example, and buy another one. Then you can and then you can use everything before it, but the the time where you compile and it it's stay. It stays working.

C

But if I release a new version and you want a new version, you have to update your subscription. I have I have but uh makes sense and you can pick and choose so it's uh for everybody. It's the 50 50 bucks per month. Isn't that much of a deal. I know it's it's it's not nothing, of course, but you get free support. uh You can see icds versions and there's a lot of stuff. You didn't even see in that package.

C

um Okay, so and the next time there will be.

B

The little builders because we can do a twitch like a light which one of the indica during the week so yeah uh also it will be gla. I will be glad that to show that to the spanish community, so I will do a spanish demo. I will work on that with you.

B

Well guys that will be everything for this uh stand up. uh Thank you thanks everyone for coming and if I can ask you something if everyone can turn on your camera, so I can take a picture because I always take a picture of all the standards we have one for each bond. So if manel you can please stop sharing, so we can get the whole screen.

B

C

I I need to stop sharing my screen if I can somehow what the real.

B

One guy, but uh he will be here in the next uh meet up anyway, so uh if anyone everyone can turn on their cameras uh like in the next minute, I will be taking some screenshots for for for the community great. We have one.

C

B

C

B

Little bit because maybe not everyone was like in front of the computer, because most people was just listening or something like that. Okay, it looks like we have like half of the people. uh Let's give it like, maybe a few seconds more.

B

So let's wait a little bit because I like this for the so I will count to three. So you do your smile or whatever you do. I'm not good, smiling! So, okay, like one two, three go great, so we have a few screenshots already. So, let's see uh one second, let's wait for me to paste them, because otherwise I will lose them and there will be no picture great. um So let me save this and I will save it in the desktop okay, everyone.

B

So thanks for coming uh thanks everyone to spend time with us, I think that the presentations were great thanks manuel. I I'm really excited about senior stuff, especially about that I can do everything in code because I'm a code first approach, type of person and I'm looking forward to see the layout builder. So we should teach about that and maybe we can meet tomorrow, because we will have a spanish meeting on on saturday. So again, thanks everyone for coming and see you guys the next month.

A

Thank you guys, bye.
