Help requested -- importing stuff from a .COM DLL into python
I wonder if some kind soul can help me in my struggle with DLLs?
I am trying -- not because I want to, but because I have been told to --
to import things from an API that exists as a bunch of .COM DLLs.
I had originally hoped to get them into a Python 2.4 program by a simple
import statement. This does not appear to work, so I secured a copy of
win32com, and have proven that it works to the extent of opening a M$
Word application.
The same approach with the DLLS I actually need to use consistently fails
with the message "Invalid class string" (full traceback included below, I
doubt that it helps). After a couple of afternoons of vigorous easter-
egging, I have not hit upon a valid class string, and my childish
assumption that it would be one of the names listed in the API
ocumentation is obviously wrong. Staring at the DLL contents with
PEBrowse tells me nothing useful.
Does anyone with experience of getting .COM stuff from DLLs know where I
am going wrong?
(Alternatively, can anyone who has got Python to use the MooD API tell me
how?)
I have no experience of .COM up to this point, and am hoping to keep it
that way once this nonsense is done with.
Thanks for any assistance, and all the best,
John.

I second the recommendation for SimPy for writing simulation programs. If you require a simulator specifically, I don't know of one in Python.

Most things don't have names? I'll believe you if you can give me a list of ten things that don't have names. ;-) All the best, John. -- http://mail.python.org/mailman/listinfo/python-list

What exciting new ideas exist in software that are both important and cannot be traced back to 1986 or earlier? I'd like to believe that there are some, but I can't think of any at the moment.

The only two I would think worth mentioning are Nygaard et al's ideas on patterns as embodied in Mjolner Beta, and Colmerauer's on logic programming as embodied in Prolog. And maybe pi calculus, if only for sticking the formal foundation in where it was missing from under O-O. But Prolog and pi calculus are regarded as marginal activities, and most software people have stil contrived never to have heard of Nygaard, despite his being the inventor (with Ole-Johan Dahl) of O-O in 1967.

That sounds more reasonable. In my more jaundiced moments, I think that progress in software will not resume until we stop the annual doubling of resources for bloatware to consume.
