WMI calls for virtualization - not returning values

ruby-talk
1

Hi,
I am using WMI calls to ge the Virtual system information of a VM on
Hyper-V using Ruby.
Below is my code:

require 'pp'
require 'win32ole'
wmi = WIN32OLE.connect("winmgmts://./root/virtualization")

processes = wmi.ExecQuery("select * from
MsVM_virtualSystemManagementService")
temp = nil
result = Array.new
input = nil

for process in processes do
  pp process.Caption
  pp process.Name
  pp ret = process.GetSummaryInformation(input,
                   [0,1,2,3,4,100,101,102,103,104,105,106,107,108],
result)
end
  pp result

ret is 0. which is for success. But 'result' is empty. Iam know that Iam
missing out something. Please do let me know how to make this work. Iam
stuck here.

Thanks in Advance,
Shreya

Check WIN32OLE::ARGV for the result. This is explained here:
