I got the VB-based doc on programming Source Safe, which claims to be a Object Model reference but is incomplete and has duplicated text; probably someone's notes that they just threw into the docs.

And, use the OLE typelib browser to find out what functions are really available and what they return. From that, and trying one line at a time and looking at the results and the actual return values, you can figure it out.

Another tip: the ole constants module uses a different name than the main OLE module to resolve the VSS target.
