I am making a class that can be used to get all the informations about the screencards on a PC. So we know what we can use in the DX app.

All the information is going to be shown in a window with textboxes and combo boxes. But I was wondering. How does it work in C++. I have seen a app that does more or less that. But that app has not any class for it at all. Does that meen that I can make a headerfile with prototypes of all the functions that I need and put the functions in the cpp file and then use them the same way as static methods in Java. Or should I use a class?
