In an MFC application you can call AfxGetMainWnd() from anywhere. This will
give you a pointer to your main window, which is the dialog in your case.
You can cast this CWnd* into a pointer to your dialog class, then use it to
access dialog members.

My application is dialog-based.
The App creates a dialog. The dialog creates a property sheet. The
property
sheet creates 4 property pages.
The dialog opens a file. I want the property pages to be able to write to
the file. How can I get access back to that file pointer? I found
m_pParentWnd in the Property Page. But, I can't go back like this
m_pParentWnd->m_pParentWnd to get two levels back.

I thought about passing the pointer to the CFile in via the contructors of
the dialog, then to the sheet, then to the pages but I am not sure how to
do
that either.

Any help is greatly appreciated.
