Hi There,

I am having a lot of probs understanding classes and inheritance.

My problem is that I want to define a structure in a dialog class (DlgClass1). I then want to open a modal dialog box class (DlgClass2), and be able to see my original structure. I have had no luck making the Base Class of DlgClass2, DlgClass1. And when I use code such as

DlgClass1* MyInpFileDlg3;

MyInpFileDlg3 = (DlgClass1*)AfxGetApp();

MyInpFileDlg3->Struct.inta = 0;

I usually get a GPF when I exit the program.

Is there an easier way to make the structure a
member variable of DlgClass2. When you answer please treat me like an idiot, and tell me exactly where to define what.

Thanks Very Much
