I was thinking of desktop spying programs used in most schools such as netop and others. The teachers can use them to draw on the screen, lock the desktop, shutdown the desktop, spy in real time what the student is doing. Now, I was thinking if I could send a bogus snapshot of the global windows Device context(0) somehow it would maybe fool the teacher.

Does anybody have any ideas on how to do this, or any other methods to fool programs like these such has hooking functions?

No need for screen shots if they see it in real time...

I was thinking they use GetDC(0) to get snapshots, I know VNC gets individual snap shots at frequent intervals and just streams them to the client.

You could check for all the connections to your computer and close the connection thats giving the feed. But what is better to do is to go to the task manager and end the process of sending feed, or stop it, whatever works for you.

I don't want the process to be killed, I want it to send a false desktop state so there isn't any suspicion

I havn't looked up enough on how the program works to think of something that can do that... (maybe you can edit the exe so instead of sending a screen cap, it'll send a picture from some directory.)

You could use CE to freeze it so theoratically it would still be using the same feed as when you froze it, depends on their program, my school used syrchoneyes or w/e its called

Best way is just to download a live linux CD and boot off of it, then you can just do what ever you want, like delete any "spying" programs of the harddisk.
