Prof.) Organization: New Jersey Institute of Technology Lines: 21 I'm a little puzzled on two points in MS Windows, perhaps someone out there could help me. 1. I am a little unsure on the differences between: InvalidateRect() and UpdateWindow(). Are the following equivalent or not: InvalidateRect(hwnd, NULL, TRUE); UpdateWindow(hwnd); If these are functionally the same, which is preferred and why? 2. Regarding timers... I can set one timer fine, but when I try to create more than one (i.e, two !) the first one doesn't seem to work anymore. Is there something fundamental that I've missed? Thanks all, Frank
