I'm not sure that you need PSBASE outside of powershell, I could be
wrong, though. GetText in OLE land is called GetText_.

Win32OLE example:

>> require 'win32ole'
=> true
>>
?> wmi = WIN32OLE.connect("winmgmts://")
=> #<WIN32OLE:0x2c50740>
>>
?> processes = wmi.ExecQuery("select * from win32_process")
=> #<WIN32OLE:0x2c280c0>
>>
?>
?> for process in processes do
?> p process.gettext_(1)
>> break
>> end
"<INSTANCE CLASSNAME=\"Win32_Process\"><PROPERTY NAME=\"__PATH\"
CLASSORIGIN=\"_
...

Ruby-WMI example:

>> require 'ruby-wmi'
=> true
>> proc = WMI::Win32_Process.find(:first)
=> #<WIN32OLE:0x2be25e0>
>> proc.gettext_(1)
=> "<INSTANCE CLASSNAME="Win32_Process"><PROPERTY NAME="__PATH" CLASSORIGIN="
...

Hope that s.
