| Yes, I had run it.
|
| And, just now I updated python, pythonwin and wmi.py to
| latest version. And got:
|
| >>> a=wmi.WMI()
| >>> a.Win32_Process.Create(CommandLine="notepad.exe") #
| --- it works
| >>> a.Win32_Process.new().Create(CommandLine="notepad.exe")
| # it still fail
| Traceback (most recent call last):
| File "<stdin>", line 1, in ?
| File "wmi.py", line 361, in __call__
| handle_com_error (error_info)
| File "wmi.py", line 208, in handle_com_error
| raise x_wmi, "\n".join (exception_string)
| wmi.x_wmi: -0x7ffdfff7 - Exception occurred.
| Error in: SWbemObjectEx
| -0x7ffbefff - Generic failure
|
| Without 'new' everything works. And does everything I need from it.
Yes, I think the simple answer is: don't use .new unless you're sure
you need to. When I wrote the wmi module originally, I misunderstood
the use of SpawnInstance_ (which is the method behind .new). To create
a process, or a share, or anything which has a .Create method, use the
.Create method. Use .new only for things like Win32_ProcessStartup,
as in this example here:
http://timgolden.me.uk/python/wmi_cookbook.html#run-process-minimised
where the instance is created only to pass as a parameter
into the .Create method of the Win32_Process.
I've updated the module docstring for the next release, and have changed
the cookbook examples which used .new where they shouldn't have, so
thanks
for highlighting the deficiency.
| And, I have another question. Is there way to access WMI from linux?
Not using this module, which is very Windows-specific; there was some
work recently on WBEM (which is the industry standard behind WMI) on
Linux, but I've not tried to use it myself:
