I think the function you are looking for is called bitblt, described on this page: http://vbgp.hypermart.net/tutoriais/BitBlt2/index.htm and on MSDN.

Its a Win32 GDI API.

>I'm building a pong game as an assignment. I am using the graphics object from the form and erasing then re-drawing the objects. I realize that this is not the best way because it is possible to draw an object and then erase another object erasing a portion of the first object drawn.

>Its been a while, but I seem to remember a way to by some kind of graphic bit manipulation you could ensure that the object your erasing is only erasing the portions which show only the background.

>There is a Clip object which I have tried to use but I am not too familiar with it. It looks like you can do a fair amount of manipulation of the drawn objects and then point that to the visible portion of your screen when you are done. I tried a number of different things but none of them seemed to work.
