virtual void PreCloseFrame( CFrameWnd* pFrame );
Parameters
pFrame
Pointer to the CFrameWnd that holds the associated CDocument object.
Remarks
This member function is called by the framework before the frame window is destroyed. It can be overridden to provide custom cleanup, but be sure to call the base class as well.
The default of PreCloseFrame does nothing in CDocument. The CDocument-derived classes COleDocument and CRichEditDoc use this member function.
