    I'm pretty sure that there are PLENTY of source code available for this type of application on the net. Of course, it would make a big difference which OS you are using...

    If you want someone to explain to you how such a think works and how to write one yourself from scratch, then you'd have to tell us a bit more about what your experience in programming is. Doing Windows/X-WIndows programming is not for the pure beginner, just like it's better to start with a go-cart if you want to start racing cars, rather than a formula one... Once you know a bit about what you're doing, then you can start working on graphical user interfaces if you like.

    Depends on the O/S.

    It's like asking, "Where's the shifting stick on a car?" Depends on the car.

    Try to be clearer in your questions in the future.

    There isn't a single Win32 API function that will take a screenshot, no. There are several ways to write an application that copies the content of the screen, but it requires a sequence of not entirely trivial calls to the Windows API. If you haven't written any code for Windows applications, it's probably not a decent starter project.

    Obviously, part of this also depends on what else you are going to do once you've copied the screen - save it as a image on disk, copy it to the clipboard, or whatever else you may want to do...

    The easiest way - and not the best, is to simulate a "Print Screen" press and copy the contents of the clipboard and dump it to disk, easy but cruddy. For example if the Print Screen Key wasn't bound to take a screenshot, or a program overwrote the clipboard while you were in the middle of getting a screenshot.
