//  MODULE:   copyhook.cpp 
// 
//  PURPOSE:   Implements the ICopyHook member functions necessary to support 
//             the copy hook portioins of this shell extension.   
//             Copy hook handlers are called each time a folder is copied, moved,  
//             renamed, etc. in the system.  Note that the CopyCallback is NOT 
//             called for each file, but only for entire folders.

//    wFlags        - and flags (FOF_*) set in the initial call  
//                    to the file operation 
//    pszSrcFile    - name of the source file 
//    dwSrcAttribs  - file attributes of the source file 
//    pszDestFile   - name of the destiation file (for move and renames) 
//    dwDestAttribs - file attributes of the destination file 
// 
//  RETURN VALUE: 
// 
//    IDYES    - allow the operation 
//    IDNO     - disallow the operation on this file, but continue with 
//               any other operations (eg. batch copy)
