I've been trying to implemt the funtion PrintWindow() (introduced in XP to user32.dll) to capture the Active Forground window, which is partially off screen and save it as a bitmap or as a blitz image. Hopefully this will return the whole window and not just the part that is visable.

However, try as I might using the examples of desktop capture in the code archives as a base, I can't seem to make this function work, mainlly due to my complete lack of understanding of DC's.
Any help would be very much appreciated.
