I've been playing around with C++, and decided on a simple app to change wallpaper depending on screen resolution, since at college(sixth form) some of our computers are 16:9 and others are 4:3.
What I want to know is what Windows API calls do I need to make in order to achieve this? And also what syntax? (e.g. Resolution(width, height)), I've had a look on google and here, but I'm still a little mystified. If there is anything compiler specific, I'm using GCC.
Thanks in advance.
