Customizing a File open dialog with CFileDialog.

     Environment: MSVC 2.2, Win NT 4.0
     
     I am trying to add a list box to the bottom of a file open dialog.
     
     According to the Win32 SDK...
     
     "You can customize an Explorer-style Open or Save As dialog box by 
     providing a hook procedure, a custom template, or both."
     
     This sounds like I don't have to provide a hook procedure, but if I 
     try to construct a CFileDialog as follows I get ASSERTS from MFC 
     complaining that there is no hook procedure.
     
       CFileDialog FDlg(TRUE);  
     
       FDlg.m_ofn.hInstance = AfxGetInstanceHandle();
       FDlg.m_ofn.lpstrFilter = szFilter;
       FDlg.m_ofn.Flags = OFN_ENABLETEMPLATE |  OFN_EXPLORER;
       FDlg.m_ofn.lpTemplateName = MAKEINTRESOURCE(IDD_DIALOG1);
       FDlg.DoModal();
     
     
     I looked at the MFC hook procedure _AfxCommDlgProc and it occured to 
     me that I probably do have to provide a hook proc to handle the 
     messages for my dialog template.
     
     But rather than write an old fashioned switch etc.  I would like to 
     find a way to use the message maps of the class associated with 
     IDD_DIALOG1.
     
     Can I use the WndProc for my dialog class as the hook proc?
     
     If so, how?  
     
     
     Thanks,

You do not use the OFN_ENABLETEMPLATE for explorer dialogs.  The trick =
is in the dialog itself.  You must enable the extended flag which tells =
the dialog it is a child of another control.  Kind of backwards from the =
usual.  Anyway;  set the "Control" bit in the "More Styles" page of your =
dialog.  Then add a static where you want the explorer and name is =
"stc32".  That's all their is to it.  No need to do anything with the =
template stuff MFC handles that for you when you create the class for =
your dialog.

I have one working that I could send you pieces of if you still have =
trouble.
