Add AfxOle.h to Your Precompiled Header File

The MFC OLE support is kept in a separate extension header file, AfxOle.h. Because several Scribble implementation files refer to the MFC OLE classes, it is a good idea to include it in Stdafx.h, the precompiled header for Scribble.

   #include <afxole.h>        // MFC OLE support
   

2. Save the file.
