something circular with #include?

[ns]

I have a View class spawning a CDialog class (used the class wizard). If I include "View.h" in mydlg.h, and include "mydlg.h" in view.h, i get bizarre errors which miraculouosly disappear if I comment out the #include "view.h" from the dlg class. BUt I wanted to use that .h file to access some info from the view class in the dlg. So I tried forward declare class myView but it doesnt like that either.... Appreciate your help, ns

In your mydlg.h, put this: class View; ( or CView, if that's it's name) Then #include it in your mydlg.cpp file.

I think you mentioned that you already tried forward declarations, and that they didn't help. You might try putting the following line in your .h file: #pragma once Otherwise, try playing with #ifndef using the (very long) names #define'd by the class wizard: #ifndef MYDIALOG_AFX_LOTSA_STUFF_THAT_LOOKS_LIKE_A_GUID #include "mydialog.h" #endif

Did you try prototyping ? Before you use a class into an other class you have to #include the header. If you only need a pointer to an other object, you can prototype this class. The compile knows the definition (pointer to a class) and the implementation is linked afterwards.
