I want to make a program that uses screenshots. It's kind of like a webcam. Only, it just monitors the screen. It's for security reasons. Okay, here's what I want it to do. I want my program to take a screenshot every 15 minutes and save the picture to a folder. I don't want any screenshot overwriting another so I want the screenshot to have a different filename every time it saves. If anyone has any ideas on how I should begin doing this, I would appreciate it.
