You're all messed up. Can't use BeginPaint() except in WM_PAINT handlers. You can use GetDC() to paint, but it won't persist (its an extremely poor practice to get into).

Oh thank! it works but your right when i close the window the message dissapear, u know a way to fix this?

Well if your using the exact message handler as shown above. Then your not handling your close calls properly.

All basic C++ message handlers have this:

case WM_DESTROY:
  PostQuitMessage(0);
  return 0;
