      • Hi! As a complete newbie programmer, I've run into a, what I think is, a basic problem. I'm working on a small Windows Forms Application in VC++ Express. As you know, VC++ by default creates a class (initially called Form1) for the GUI. What I need is to use this type, Form1, as an argument in some of the methods in my own classes, which I define in a separate header. This is because I want to do
