I've been playing around with a library that would provide an activerecord style interface to WMI.  So, instead of this:

<code>
require 'win32ole'

LOGOFF = 0

computer_name = 'host'
wmi = WIN32OLE.connect("winmgmts:\\\\#{computer_name}\\root\\cimv2")
list = wmi.execquery("Select * from Win32_OperatingSystem",nil,48)

list.each do |item|
  item.win32Shutdown(LOGOFF)
end
</code>

You'd have something like this:

<code>
require 'wmi'   # or whatever it's going to be called

LOGOFF = 0

computer_name = 'host'
os = WMI::Win32_OperatingSystem.new(computer_name)

host = os.find(:first, :condition => {:primary => true})
host.win32shutdown(LOGOFF)
</code>

My aim is to have an easier to read, more rubyesque way to work with WMI.  I've been thinking about opening a rubyforge project if there's any interest.  But I don't know what to call the thing.  Here is a list of names I've come up with.  I don't really like any of them, though, so I'm open to other suggestions.

active_wmi
ar_wmi
wmi_rb
ruby-wmi
rWMI
wmi4r

Thanks,

Gordon
