[python-win32] Getting Network Information/Statistics

[>.>]

That works for XP but not Vista, I guess M$ changed the API in Vista. Oh by
the way I mean to write win32pdhutil.browse() earlier. Thanks for the help.
I didn't run it as admin in Vista before so I gave your script a try.
The output from your script as run in vista by administrator follows:
[code]
>>> win32pdhutil.browse()
Value of '\Network Interface(Intel[R] PRO_100 VE Network Connection)\Current
Bandwidth' is 100000000.0
Added 'Current Bandwidth' on object 'Network Interface' (machine
\\SAIBOX-01), instance Intel[R] PRO_100 VE Network Connection(0)-parent of
None
>>>
Traceback (most recent call last):
  File
"C:\Python25\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py",
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Python25\getrcv.py", line 10, in <module>
    tp,val = win32pdh.GetFormattedCounterValue( hc, win32pdh.PDH_FMT_LONG )
error: (-1073738810, 'GetFormattedCounterValue', 'No error message is
available')
>>>
[/code]
I'm new to working in windows and am curious as to how to go about getting
the error codes, I tried hex(1073738810) but thats not right.
