Note also that when you wish to move or replace one of the items you have drawn, you can BitBlit the client bitmap with the original item in an XOR mode to remove it and then in a SRCCOPY mode with the new one. Also, after doing that you want to show the new image on the screen, it's just a case of doing an InvalidateRect and UpdateWindow and only invalidating the rectangle that has just been altered will further minimize the drawing time. .
