I have got some information after doing a search.I think so this will help you in some causes.This can be used to show or hide docked or floating control bars.To make both fixed-size bars and resizable bars visible/invisible, the CFrameWnd::ShowControlBar() method should be used. The CControlBar::ShowWindow() cannot be used here, because it does not affect the positions of other bars in the same frame window.
