what operating system? (there isn't only one) what compiler are you using, and more importantly what class library or API are you using? (there are multiple compilers per platform and multiple APIs and class libraries)
Well I am using Windows XP Professional SP2. I am using the Bloodshed Dev-C++ Version 4.9.9.2 compiler. I am not sure of which library to use. Can you help me?
Two ways come to mind; you can call GetCursorPos, which is part of the WinAPI, or you can check for WM_MOUSEMOVE in your message loop and pick up the position from lParam.
I am new with C++ and don't know all the codes. Can you guide me on how I can start the program and then I'll take it from there please.
If you've only just started I suggest you leave the GUI stuff until you've got the hang of the language. If you don't know how to call GetCursorPos then that sort of stuff is way too advanced for you at this stage.
