But even so, the program knows about two menus: one for when an MDI
document
is open, and one for when one isn't. I need to replace both.

You can do that as well...

Thanks Ajay,

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
round it.

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
new ones.

I'll suck it and see.
