Can someone tell me if it is possible to create a memory DC set it to a Global type long variable, and then later delete it and reinstate a new memory DC in its place to that same variable.

So far trying to to this has produced extreamly strange results with sprites displaying sparatically and what not.

I'm am trying to do this to save memory when I don't need certain sprites.
So any other idea's on how I might accomplish that are welcome.

Currently I can create 311 memory DC's before I run out of memory on a 128meg machine with the type of sprites I am using. Ideally I'd like to be able to create 500. I've found that the file type as in monochrome bitmaps don't seem to take up much less space then 24 bit color bitmaps do although decreaseing the size of the bitmaps helps.

any ideas please?
