The CExtHookSink class allows the classes derived from it to watch for and/or intercept messages sent to some other windows before these messages are delivered to these windows. For instance, the CExtMenuControlBar class, which is derived from CExtHookSink, implements a menu bar. This allows the menu bar to hook the MDI client area and active MDI child frame window in MDI applications. This makes it possible to synchronize menu bar’s buttons when the active MDI child frame window is created and destroyed or when it changes . Besides in the menu bar the MDI document button and [_][o][x] button are displayed when the active MDI child frame becomes maximized. Otherwise these buttons get hidden.
Please note you don’t need to use the CExtHookSink class in your projects if you are not going to code your own controls.
