Hi Mark,

Thanks for the answer, I tried using the IViewDataView's uiid like
this (probably in a naive way):

y = view.QueryInterface("{8D2AD79B-1ADD-4181-BAD4-FF0672A9B6E3}")

But that produces the error on that line.

com_error: (-2147221005, 'Invalid class string', None, None)

I read that I can do the same thing with win32com (without using
comtypes) but for that I would need to somehow add my custom interface
to it. I also read that exist tools to automate this process but so
far I could not find them. Where should I start?

Cheers
Jose
