Re: Substituting the main menu bar(s)

But even so, the program knows about two menus: one for when an MDI
is open, and one for when one isn't. I need to replace both.
You can do that as well...
I have been exploring the MFC source code and I think I can make it work.
For the menus shown when there is a document present then from the CWinApp
derived class one can do
POSITION pos = GetFirstDocTemplatePosition();
while( pos )
CDocTemplate *pDocTemplate = GetNextDocTemplate( pos );
// Cast this UP to CMultiDocTemplate - it is one!
// Replace its m_hMenuShared with my new HMENU for the document.
I am a bit nervous about needing the upward cast (on the principle that
something is usually awry if an upward cast is needed) but I can use
IsKindOf to check the legality, and it works. And there seems to be no way
For the menu when no document is present, as you say, I can replace the
m_hMenuDefault of the base class of my main frame window.
Now I need to be tidy. I am assuming that each document type stores a menu
handle in its CMultiDocTemplate::m_hMenuShared and the menu for no document
open is stored in CFrameWnd::m_hMenuDefault, AND that MFC simply uses
SetMenu() to select between them as document windows open and close, without
destroying the previously selected menu.
If so, when I replace the stored menus, it looks like I should be destroying
the old menus and simply using SetMenu() using the appropriate one of the
I'll suck it and see.
