Drawing over a program..

Hi.

I'm not really sure about the technical side of this but here goes. I am making a program which must be visible over a Direct3d game. From what i have read it is impossible to have a form stay above a direct 3d app, the only way would be to draw directly over it.

I've never done any graphics programming before and am not sure if this is a a big task or not.

Could anyone please tell me how this is done, or point me in the right direction to learning the basics for this type of thing.

Thanks in advance.

Ah, I'm not sure exactly what you're trying to do, but... That's next to impossible if the app is fullscreened, short of having something either find where in memory is the backbuffer or having a program run alongside the (game, I'm assuming?) and plotting directly to the screen after it updates.

In short, it's just about impossible with VB, and extremely hard even in C++.
