[python-win32] Try to got short path for files - but goterror...

[Metz, Bobby W, WWCS]

FYI,
	looking around a bit on Google it appears this question has been
posted before without a clear answer...in fact, lots of places without
clear answers.  One guy went so far as to "cheat" as he put and used
WSH.  But that's not much better than my "cheat".  So, aside from Mark's
short code request, I'd suggest spending some more time with Google.

Mark,
	Do you know if it's possible to get all the usual "right-click"
file properties using win32com or ctypes?  I know Windows presents short
names via properties, but wasn't sure that's exposed via either.  I
googled this but didn't see a clear direction after the first 50 hits.
May be a bad search on my part.

Bobby

I'm afraid your message isn't very clear.  You should try and copy the
smallest possible code that demonstrates your problem, exactly as Bobby
did
in his reply.

Is that what you mean?  You have a literal backslash, followed by 'xa',
followed by unicode char ff.  Eg:

>>> u'%s\\xA\xff'%os.getcwd()
u'c:\\src\\xA\xff'
>>>

The 'xA' is *not* a unicode char in your example.

There is no way you can do that.  Windows allocates the short name for a
file as it is created.  That short name is not guaranteed to be the same
on
2 different machines.  The only way to get the short name is to ask
Windows
for it.

Note that Windows uses MBCS encoding - so you can use
win32api.GetShortPathName(filename).decode('mbcs') to get the unicode
filename.  That only works if the unicode characters are all in your
current
codepage, but that is usually the case.  GetShortPathName does need
upgrading to accept a unicode object and in that case call
GetShortPathNameW.

Cheers,

Mark
