This is sorta an answer to my own posted questions on menus in dialog
boxes.

The issue is how to use functions created/mapped by Class Wizard to
ON_COMMAND_UI messages in a dialog-based app. Normally, they don't
wrok, as they're usually handled by CFrameWnd, which a dialog app

gave a clue, and this is my formulation of it. It's just a re-hash of
what Kenneth posted, but formulated into nice files you can add to
future project easily. Hopes this helps some one else, and thanks to
Kenneth for the pointer.

/********************************************************************

This function is used to use the ON_COMMAND_UI command mappings in
dialog-based apps. Normally these won't work for a dialog app, since
they're normally hannled by CFrameWnd, which a dialog-based app lacks.
You can, however, use these Class Wizard created mappings (which shows
up in the CWinApp based class, not the dialog class), by the following
method:

1. Use Class Wizard to map ON_COMMAND_UI for menu items in the usual
fashion. Note that they're mapped to the CWinApp-based class, not the
dialog class.

2. In the dialog class, add ON_WM_INITMENUPOPUP() to the message map
list, *OUTSIDE* of the "{{AFX_MSG_MAP(CVersDlg)" block (sorry, Class
Wizard won't do this for you).

3. Add the following function to the dialog header file:

    void    OnInitMenuPopup(CMenu *, UINT, BOOL);

4. Add the following function to the dialog implementation (.cpp)
file:

    void CYourDlg::OnInitMenuPopup(CMenu *a, UINT b, BOOL c)
    {

        DialogMenuUpdate(this, a, b, c);
        CDialog::OnInitMenuPopup(a, b, c);
    }

(using the correct class name for 'CYourDlg', of course). Also,
#include this header file you're reading to the dialog class
implementation file.

5. Add 'DialogMenuUpdate.cpp' to your project.
