// CCJMenuBar implements an Office 97-style menu bar. Use it the way you would

//
// * Create the CCJMenuBar from your OnCreate or OnCreateBands handler.
//
// * Call LoadMenu to load a menu. This will set your frame's menu to NULL.
//
// * Implemenent your frame's PreTranslateMessage function, to call
//   CCJMenuBar::TranslateFrameMessage.
