I have an MDI application using different menus depending on the current document template in use.

I need to show the top-level File Menu from the IDR_MAINFRAME window when a command is sent from the active document.

I would like to application to deactivate the active child window and then show the File menu as if the alt-F key was pressed from the keyboard.

I have tried CMenu *pMenu=AfxGetMainWnd()->GetMenu();
but this does not display the menu at all.
