In your case, it'll be not quite that simple since the bar across the top of the window isn't of uniform height. You may need 5 images to cover the top - the two corners, the low part, the high part and the transition between the two.

case WM_LBUTTONDOWN:

 if(//checkcurosorlocationforcorner)
 {
   SetCapture(hWnd);
   mResize = TRUE;
 }
break;

   <code>if (mResize)
