Hi,

I am trying to get process information from Windows server. Using  
examples I have found on the web and in documentation I have come up  
with the following script.

require ‘win32ole’

```
 wmi = WIN32OLE.connect("winmgmts://")

 processes = wmi.ExecQuery("select * from win32_process")

 for process in processes do
    process_list = {process.ProcessId =>

```

“#{process.ProcessId}:#{process.CreationDate}:#{process.WorkingSetSize}:#{process.KernelModeTime}:#{process.UserModeTime}”}  
p process\_list  
end

I would like to be able to call the Win32\_Process.GetOwner method from  
the WMI class and include the process owner in the output of the above  
script.

I would appreciate any assistance.

Thanks.

Cheers, Barrie

You can call GetOwner method for each process like this:

```
   ret = process.execMethod_('GetOwner')
   p ret.User
   p ret.Domain

```

Thank you for your help. It is exactly what I wanted. I spent a few  
hours trying to work out how to use GetOwner.
