How to Use Multiple Menus in MFC App That Uses GetDefaultMenu

MORE INFORMATION

1. Create a new menu resource (IDR_MYMENU1) in the resource editor.
2. Add an HMENU data member to CMyDocument and override GetDefaultMenu() to return this data member:

      // .h file
      //    HMENU m_hMyMenu;
      //    virtual HMENU GetDefaultMenu(); // get menu depending on state
      HMENU CMyDocument::GetDefaultMenu()
      {
         return m_hMyMenu;    // just use original default
      }
   						

   Remember to initialize this member variable to NULL either in the constructor or CDocument::OnNewDocument().
3. Change and redraw the menu at the desired times. For example, when switching between splitter panes, this is normally done in CView::OnActivateView(). The following code shows how to implement it in that function.

      // example within CView member function
      ((CMyDocument*)GetDocument())->m_hMyMenu = ::LoadMenu(
          AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_MYMENU1));
      ((CFrameWnd*)AfxGetMainWnd())->OnUpdateFrameMenu(NULL);
      AfxGetMainWnd()->DrawMenuBar();
