[python-win32] Problems with py2exe and COM

[Giles A. Radford]

OK, I'm obviously having a bad day, cos I can't seem to get this to
work. I feel this is lack of understanding on my part, cos I can't find
much documentation on the win32com modules - is there a secret
documentation stash that I'm missing?

I'm trying to create a DLL with some COM classes that update some websites
with certain details.

The problem I have is that I manage to get py2exe to compile the
program (with a few warnigns about classes refrred to that just don't
exist - I don't have Carbon.Folders for instance), but when I try to
register the DLL with regsvr32.exe, I get back a message which said
(paraphrased from spanish) "Error in DllRegisterServer in webupdate.dll
- Returned a code: 0x80040201".

I have no idea what this means. I've been fiddling wiht it all day, and
I'm tired of it now. The fact that I can seem to find no documentation
on the process, and what it's suppsed to do. Also, if I try to compile
the py2exe with --debug I end up with a rather abstruse and
impossible-to-decypher error:

...

I really don't know what I'm doing here. I can't work out from the
source what's supposed to be happening, so I'm at a bit of a loss.

Anyway, can anyone help me work out where I'm goign wrong? or at least
shed some light as to where I can find out?

Here's some of my code, though I've had to keep the site update stuff
out for clarity. I've liberally peppered it with "what does this
actually _do_?"-style comments, and any elucidation you could provide
would be welcome.
