Here are some utils to assist in reverse-engineering OLE applications. 
Use on Win32 may require addition of BINMODE.

guidextract.pl - find and label OLE GUIDs in an executable
guids.txt - list of GUIDs and interface names from my registry
reg2guidlist.pl - make your own guids.list from a registry export file
listmethods.pl - list interface methods and offsets in Vtbl
