virtual void OnUpdateCmdUI( CFrameWnd* pTarget, BOOL bDisableIfNoHndler ) = 0;
Parameters

Remarks
This member function is called by the framework to update the status of the toolbar or status bar.
To update an individual button or pane, use the ON_UPDATE_COMMAND_UI macro in your message map to set an update handler appropriately. See ON_UPDATE_COMMAND_UI for more information about using this macro.
OnUpdateCmdUI is called by the framework when the application is idle. The frame window to be updated must be a child window, at least indirectly, of a visible frame window. OnUpdateCmdUI is an advanced overridable.
