Search "GF" or "Girlfriend" in http://www.yahoo.com, you will get the answer you desired I think.You can also search it in MSDN, most developersdo
that first if they need information.
Important:do
NOT type the "GF" as "GPF".
Hope it helps. ;-)
(Sorry, I'm can't input chinese now, it seems my keyboard has something wrong here, I will find the solution in yahoo or MSDN later. Thanks)
