This is in our windowproc:

case WM_PAINT:
  {
    PAINTSTRUCT paint;
    BeginPaint((HWND)hWnd, &paint);
    EndPaint((HWND)hWnd, &paint);
    return 0L;
  }

case WM_ERASEBKGND:
  return 1L;

And this is our window class setup:

 wcex.cbSize = sizeof(WNDCLASSEX);
 wcex.style   = CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS;
 wcex.lpfnWndProc = (WNDPROC)WindowProc;
 wcex.cbClsExtra  = 0;
 wcex.cbWndExtra  = 0;
 wcex.hInstance  = (HINSTANCE)m_hInstance;
 wcex.hIcon    = LoadIcon((HINSTANCE)m_hInstance, "PRAETORIANS");
 wcex.hCursor   = LoadCursor(NULL, IDC_ARROW);
 wcex.hbrBackground = NULL;
 wcex.lpszMenuName = NULL;
 wcex.lpszClassName = "Ventana";
 wcex.hIconSm  = LoadIcon(wcex.hInstance, "SMALL.ICO");
 RegisterClassEx(&wcex);
