OLE: Volume Shadow Copy - "OLESysError Not Implemented" Options

Hi

I am trying to use Volume Shadow Copy to backup opened exclusive files under
Windows XP. I used an article published in Delphi Informant Magazine,
September 2005 (Delphi code is available from their web-site). I obtained a
copy of the C headers for vss, vsbackup and vswriter as the XP and 2003
implementations are different (VSS SDK).

I eventually got the 2003 version working without problems:


I then set about re-coding the Delphi version of the headers for Windows XP,
and have had partial success, or to put it another way an impassable
failure:


When  IVssBackupComponents::GetSnapshotProperties is called the system
returns:


"OLESysError Not Implemented" (this does not seem to be a VSS error)


Does anybody know why this error should be returned?


Has anybody converted the VSS headers for Windows XP into a Delphi unit?


Thank you
