[DotNet-OSGeo] screen capture help

[Michael P. Gerlek]

Oh, I was thinking "capture" in the sense of grabbing a screenshot - not capturing keystrokes!

Sorry, I'll go away now...

Sounds like he's trying to write the equivalent of a keystroke tracker to record people's login passwords on a system where it shows the letter you just typed but hides the other letters.  If each keystroke triggers a snapshot during the log-off stage, he could conceivably set it up so that everyone that used that computer would inadvertently store their passwords in picture form on disk.  Sounds like hacker stuff to me. =P.

But I'm a sucker for a good puzzle.  For a logged off user, you certainly couldn't unless the process was running as a service.  There might be some old win32 API that could get the system's default backdrop.  Beyond that, my (weak) understanding of the Windows OS tells me you're in the realm of the distinctly nontrivial.

(Of course, you could always use a VM or remote desktop setup, and have the parent/host do a capture of the guest OS window...)

Can you explain what the problem is that you're actually trying to solve?
