Hi,

I have a very simple MDI example that I have been using to test ideasbefore incorporating them into my real application. I have been workingon dynamic menus from the main menubar, using OnInitCommandsPopup.

The routine gets called OK and some initial tests indicate that inprinciple I can do what I want. However the simple applicationhangs on the following code.

void CMainFrame::OnInitCommandsPopup(CXTPPopupBar* pPopupBar)
{
      // get the list of commands for the popup.
    CXTPControls* pControls = pPopupBar->GetControls();

    // Iterate through the list looking for the entries with the
    // extension markers.
    CXTPControl* pFirst = pControls->GetFirst();
    CXTPControl* pEntry = pFirst;

    long nIndex;
    CString caption;

    while (pEntry != NULL)
    {
       caption = pEntry->GetCaption();
       nIndex = pEntry->GetIndex();

         // If caption has extension marker, then include extended menus.
         // ...

       pEntry = pControls->GetAt( pControls->GetNext( nIndex, 1 ) );

         // GetNext cycles to beginning, so check for end of list.
       if (pEntry == pFirst)
       {
           pEntry = NULL;
       }
    }
}

This is simple to reproduce in a basic MFC MDI program (mine has acouple of other examples in such as child window tabs, etc. so I havenot tried taking all of the other code out), as follows:

1. Run application.
2. Select the standard 'Window' menu option, its menu should appear.
3. Drag mouse right to the 'View' menu option and its menu should appear.
4. Drag the mouse back to the 'Window' menu option, its menu should appear.
5. Drag the mouse back to the 'View' menu option. This will result in the application hanging.

Any advice or help here would be much appreciated.

Thanks,

Bruce.
