My guess it's somehow receiving a WM_QUIT message, because that is what the while loop revolves around ( which according to the proc function happens whenever a WM_DESTROY message is processed)
The window automatically closes whenever i use PeekMessage instead of GetMessage , Im using PeekMessage in order to run the loop at maximum speed
int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
MSG msg;
if(!CreateMainWindow(hinstance, nCmdShow))
return false;
//this works
while (GetMessage(&msg, (HWND) NULL, 0 , 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return (int) msg.wParam;
UNREFERENCED_PARAMETER(lpCmdLine);
}
//this automatically closes the window
int done = 0;
while (!done)
{
if (PeekMessage (&msg, NULL, 0 ,0, PM_REMOVE))
{
if (msg.message = WM_QUIT)
done = 1;
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return msg.wParam;
UNREFERENCED_PARAMETER(lpCmdLine);
here's the simple WinProc function
LRESULT CALLBACK WinProc ( HWND hWnd, UINT msg, WPARAM wParam, LPARAM
lParam)
{
switch( msg)
{
Case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc ( hWnd, msg, wParam, lParam);
}
You are assigning WM_QUIT to msg.message instead of comparing it.
