Thank you for your quick answer. Unfortunately I get the same error message.
BTW, is WMI case sensitive regarding method names? If I run your example
with 'print log.BackupEventLog', I get the error:
<dump>
>>> c=wmi.WMI()
>>> log=c.Win32_NTEventLogFile
>>> print log.BackupEventLog
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\Python25\lib\site-packages\wmi.py", line 474, in __getattr__
handle_com_error (error_info)
File "C:\Python25\lib\site-packages\wmi.py", line 188, in
handle_com_error
raise x_wmi, "\n".join (exception_string)
x_wmi: -0x7ffdfff7 - Exception occurred.
Error in: SWbemObjectEx
-0x7ffbefd1 - Invalid method Parameter(s)
>>>
</dump>
Both 'lf.BackupEventLog (ArchiveFileName="c:\\temp\\blah.blah")' and
'lf.BackupEventlog (...)' returns the same error though
