How do you change your screen resolution in a batch file, or in C/C++. I'm currently sharing this computer and I like a certain screen resolution while the other user likes it different. How do you change the screen resolution per user in windows xp. I thought I might do it in C/C++ or in a batch file and just put it in startup, but I don't know how. How do you do that? Unless you know of another way to get it so you can have it different for each user.
