in other words, I am thinking of an app that could sort of "see" my entire computer screen. Well, I can programmatically find out width and height of the screen in C#, so now the only thing missing is actually finding out the color of the pixels by their absolute coordinates. Does anybody know how to do that?
I once wrote an app to do something similar for a demo -- took a screenshot, popped open a top-level window and painted the snapshot on it, then did lots of stuff underneath to the running apps where no one could see, then removed my top-level window when done. Worked like a charm :)
Similar approaches are a great source of practical jokes. One thing you can do is take a snapshot of a coworker's screen and set it as their background image. Then minimize all the apps. Somehow none of their apps respond when they click on them :)
Search for "screen capture" on codeproject. There are several sample applications that should get you started, like this
"...take a snapshot of a coworker's screen and set it as their background image"
Yeah, that reminds me of a series of practical jokes that were played on a team-leader on a project I used to work on. As well as the screenshot as background image, the LAN admin guy changed his account to require a change of password every day, each with a minimum of 16 characters.
It is amazing what some people will accept if they think it is "official policy".
