Last question: is it possible to suppress the beeping of a wxWidgets program altogether? Or will there always be some cases that a program will beep, because wxWidgets is using Windows directly (if I understand correctly) and Windows will beep? The majority of controls in wxWidgets are wrappers aro...

I'm almost certain that it's Windows itself that plays the beep, not wxWidgets. I only found thit post about suppressing the beep under Windows, but it seems like an unreasonable amount of effort: https://stackoverflow.com/a/55885061 I also think that the beep is justified when the user enters text ...

I don't know much about sockets, my feeling tells me that separate threads for reading and writing should work without a mutex. But i also think one thread per socket would be nicer ;) Try asking on the wx-users group where you can reach the core wx devs: https://groups.google.com/forum/#!forum/wx-u...

The error message is pretty clear, you should not create the socket in a secondary thread. As your whole application uses sockets in event-driven mode, you can't just change the socket to blocking mode and expect it to work. Besides, as far as i can see, all threads in your code are pointless at the...

Well, I do need to share some const strings(wxString) between classes, any good way to avoid this issue?

Initialize them at run-time, e.g. with a static Init() function you call from wxApp::OnInit()

The main issue is still that if you use _() for global variables, wxWidgets functions will be called before wxWidgets itself is initialized. Which may work or not and should be avoided.

In general, there shall be no global variable of a non-trivial wxWidgets class.

In the mysocket constructor, you create one client socket: You need a separate socket for each outgoing connection.

Don't want to be annoying but I am also wondering how get sub image in the shape of a circle. wxImage offers only method with wxRect argument. As you already noticed, there is no ready-to-use function for this. I would add an alpha channel to the image (if it doesn't already have one) and set all p...

Panel->Bind(wxEVT_MOTION ,&Control::OnMove,control); MainFrame->Bind(wxEVT_MOTION , &Control::OnMove, control); control->Bind(wxEVT_MOTION , &Control::OnMove, control); Theoretically this should work, but it's unclear what the visual hierarchy is. E.g. the MainFrame is probably completely covered b...

Just call wxYield() after creating the wxSplashScreen

This should be:

Ok, i opened /samples/minimal/minimal_vc15.sln (the highest i found) and built it with "Build Solution". Did it compile and did you actually run the sample? This was all just to confirm that the building of the wxWidgets libraries was successful. If yes, then it's probably just a matter of wrong li...

Yes, In <wxdir>/samples/minimal/, use the highest version solution file.

Then proceeded to build it manually by opening build/msw/wx_vc16.sln as i didnt find any higher versions. I used the batch build and used select all option, so im guessing i have built everything there is to build. So building the wxWidgets libraries was successful? If yes, then the next step shoul...

But I'm still confused about drawing with fixed value(blue rectangle) is working, and the dynamic value not(red rectangle)?

When you increase the window size, the OS will only generate update rectangles for the small, new parts that become visible, not the whole window.
