Thread: two windows

Close the splash screen from the main window's create event

Code:

case WM_CREATE:
  // Do something, and finally:
  SendMessage(hWndSplash, WM_CLOSE, 0, 0);
  break;

Let me guess, you're posting a WM_QUIT message somewhere in your splash screens window procedure? (Either SendMessage(hWnd, WM_QUIT, 0, 0) or PostQuitMessage(0))
Here's a quote from MSDN:

If the function retrieves a message other than WM_QUIT, the return value is nonzero.

If the function retrieves the WM_QUIT message, the return value is zero.

If there is an error, the return value is -1. For example, the function fails if hWnd is an invalid window handle or lpMsg is an invalid pointer. To get extended error information, call GetLastError.

So if your code looks something like this:

Code:

while (GetMessage(...) > 0)
{
     TranslateMessage(&msg);
     DispatchMessage(&msg);
}

Then GetMessage will return 0 when the WM_QUIT message is posted and your program will exit. Solution: Don't post a WM_QUIT message in your spash screens window procedure.

You're right, Eibro, that was my problem. Thanks for the help
