I think you may have to disable m_bAutoMenuEnable member of CFrameWnd. Otherwise enabling/disabling menu items handles automatically

from MSDN:

CMainFrame::CMainFrame()
{
// Set to FALSE so no ON_UPDATE_COMMAND_UI or
// ON_COMMAND handlers are needed, and
// CMenu::EnableMenuItem() will work as expected.
m_bAutoMenuEnable = FALSE;
}

That could cause a few problems, but works better than manually doing it.

The best way to do it is to handle the On_Update messages sent for than menu item.

ON_UPDATE_COMMAND_UI(ID_VIEW_ITEM2, OnUpdateViewItem2)

void CMyClass::OnUpdateViewItem2(CCmdUI* pCmdUI)
{
//You can replace false with a variable to keep track of whether you want the menu enabled or not
pCmdUI->Enable(false);
}
