Handling Com Events in Python (was Python and Windows Scripting Host)

[Syver Enstad]

Cool of you to really shake out the behaviour of it. I am going look over
your source to learn more Python.

Yes, not so sweet to poll it. Maybe we could use the propertyChange event to
decide when to poll? Have never tried it so just suggestion. Must remember
to check that out.

Cool idea with the BeforeNavigate things. I am currently working on a
project involving a plugin/browser extension in Microsoft explorer, where we
modify web pages the user visits on the fly so I was naturally using IE
automation to check out the Python COM support and how far you could push
it.

Regarding the missing DocumentComplete events, I think I have experienced
something similar when using a console application (C++) to automate IE.
Don't think I got DocumentComplete events then either.
