desktop-application | Electron-based desktop time tracker for Cattr | Dektop Application library

For reference, I am new to C#/WPF/PostgreSQL and I am trying to create a project for practice, however I've hit a bit of a roadblock. I found this earlier and tried following along with the answers (I understand it isn't 1 to 1) with my own code: Retrieving data from database in WPF Desktop application but it didn't work in my case.

I am creating a simple recipe app where a user can create a recipe (e.g., put in the title, steps, things they need, etc.) and on the home screen, they can see a link to the recipe that was saved, which would take them to the Recipe Screen to be displayed if clicked. I am using PostgreSQL for my database and I do see the correct information on there after the user would submit all of the necessary info, I just need to retrieve it and put it in a data grid possibly? Unless there is a better way other than a data grid.

Regardless, I plan to have it shown as a list of just the title of the recipe, where a user can click on it and it would load up the page, but that's something I can tackle another time if that is outside of the scope in regards to my question.

Here is a visual idea of what I'm trying to accomplish:

Here is my code for the submit button found in the Create Screen if it helps, however I have no idea what to do in terms of actually retrieving that data and then displaying it on my Home Screen.

Creating my first Electron app, following Feronato tutorial Part 1. This places Electron as developmental dependency using npm install --save-dev electron. Building on 64 bit Windows computer, this results in 64 bit Electron app. Also, would like to build a 32 bit app.

(1) Can I change the code to add --ia32 flag to create a 32 bit app? For example, npm install --save-dev --ia32 electron (2) Do I need to separately install Electron 32 on computer?

So far have not been able to get this to work.

Attempting to implement NavigationView navigation via code-behind using this solution I found: https://xamlbrewer.wordpress.com/2021/07/06/navigating-in-a-winui-3-desktop-application/ I don't know what I am doing wrong. :-(. I am new to C#, WinUI. Where is 'App.Navigation'?????

Outline of solution:

1. All navigation-related code is implemented in a partial class of the Shell window,
2. encapsulated in an interface that is
3. exposed via the App instance to
4. the different XAML pages.

I created an interface: (INavigation.cs)

I'm following the tutorial here.

Here's the code I'm using, copied from that site:

I have created a JavaFX application. It runs perfectly in my Intellij IDE. Now I want to distribute the application - i.e. I want to obtain an installer that users could download and then it would install the application for them.

I found a very interesting article about this here. This blog article basically describes what I want to achieve. There are two differences though:

1. I am using Maven and not Gradle

2. I have dependencies which use automodules such as iText7 and apache.commons.lang3

The usage of automodules is making things very complicated. There is a GitHub project called ModiTect (here) that has been written to solve these issues. I have no experience in using ModiTect though and even my Maven knowledge is barely existent (meaning: I don't really know what I am doing in the pom.xml).

What I am looking for is an explanation (step-by-step) as on how to integrate ModiTect (and if necessary jpackage) into my pom.xml in order to obtain an installer for my JavaFX application that uses automodules (and also a sqlite database, which shouldn't be a problem though).

Can somebody provide this explanation or refer me to a tutorial?

I provide a MWE at the end of this question. The MWE ist a TestApp. To illustrate the problem, run the application and press the "Print PDF" button. A pdf is created in resources --> pdf

The MWE will compile and run when executing javafx:run There will be an error related to the usage of automodules when executing javafx:jlink

I don't know how to fix this. ModiTect appears to be a promising addon. Another possible way can be found in this GitHub repo. But as I said before: My Maven knowledge is not sufficient to really grasp what is going on here. Any help would mean a lot to me!

I'm developing a WPF (Desktop Bridge) application that performs some logic on startup and in out-of-process background task. This logic creates and uses a file in the user's Documents folder.

I've created out-of-process BG task in WPF (Desktop Bridge) application according to the article on Microsoft Developer Blog: Link

To use the Documents folder, I've added the appropriate permission to the manifest of Package project:

This is very early stages therefore no code, but some architecture questions maybe.

Im looking into trying to create a walkie-talkie functionality from ex a desktop-application or android application can send its audio to a server and that server then distributes the stream of audio to all clients.

My issue is that we are talking about both WIFI and LTE/4G network so has to work over the internet, and in theory should be possible to push audio from 1 to 1000 clients ( or select clients )

A small delay from speaker to its distributed isnt a big problem since its only one way communication ( not a like a phone with two way communication ).

Alot of questions arise here, mostly about size and speed :

1. primary thing im considering if i need to talk out to 1000 clients ( as in many many clients ) at the same time, i assume those 1000 clients all need a few sockets that is connected to the server, and therefore probably have to split it over more than one server to handle such kind of load ? ( i dont know ).

2. signalling part - would it be possible at all to have a signalling service handling that many clients ? ( assume the signalling needs also a constant connection to the server to be able to react when theres a audio-stream coming out, as it has to be fairly quick to react when someone speaks )

3. the protocols i have looked into on an overall perspective are SIP for signalling and RTP over TCP for transport, alternatively looked briefly at XMPP and fun-XMPP for inspiration, and in theory i can see it work on a small scale but my brain breaks when i try to imagine it on a large scale.

Core architecture was ex having a server handling SIP for signalling and keeping track of clients ( if SIP is fast enough/real-time enough which i am in doubt of ) - and then a transport server that the client would connect to with its audio-stream and then that server would channel that data out to all clients through the connection made when SIP recognizing someone is 'calling' them.

Side-question to this would be that i would like to have Go as back-end to manage this routing of data to all clients as a kind of media streaming server - but not sure if its fast enough ?

Maybe i am am totally wrong with the approach and protocols - maybe a way better approach then also interested in what you would suggest instead.

I am creating the installer using the following command. I am giving jpackage the icon to use

I know there is a way to use UWP methods from WPF apps.

My question is whether there is a way to use those methods from a .Net Standard library. Just adding the references mentioned here doesn't help. It doesn't recognize them.
