Why won't the window display?
) a while loop like:while(GetMessage()){ TranslateMessage(); DispatchMessage();}That's just some quicky psuedocode so check the documentation.
Also, why did you comment out ShowWindow() and UpdateWindow()?
And, you should at least call DefWindowProc() in the WinProc procedure. This handles messages you don't.
And you can probably leave out main_window_handle and just use your hwnd var wherever you use it.
Good Luck
All I am doing is createing a basic window class, registering it and trying to display it. I get no complie errors, but when I run the .exe nothing happens...Why not, what am I missing?
