BOOL CWnd::SetMenu( CMenu* pMenu );
Identifies the new menu. If this parameter is NULL, the current menu is removed.

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (baseCMainFrame::OnCreate(lpCreateStruct) == -1)
        return -1;

    SetMenu (NULL); // turn off the menu...

    ...

    return 0;
