I see that is possible to draw something in other process window. How this can be done.
For example, FRAPS and Teamspeak overlay can display text information when you play games (directx or opengl) even when you play games in full screen.

Is there any solution to make Delphi program with similar functionality which have 2 mentioned programs.
In my case I only need to draw to OpenGL game.

Hi,

the thing your are looking for is called "DLL Injection" or "API Hook".

Lossy Ex made an example application once, you can still find it here.

You should also take a look at the uallCollection, it offers some function to do inject DLL's.
