require 'win32ole'
ie = WIN32OLE.new('InternetExplorer.Application')
ie.Visible = 1
ie.navigate "www.google.com"
That’s the basics for it. I found another basic intro from Ruby on Windows blog .. And don’t forget you can instantiate an object and then do something like..
properties = ie.ole_get_methods
to get more information. This comes in very handy
