Answer 1

I still think you're in the wrong place here asking about Visual Basic... but here's an online reference: http://msdn.microsoft.com/en-us/library/sh9ywfdk.aspx and here's a book: http://www.barnesandnoble.com/w/visual-basic-2010-rod-stephens/1102489160?ean=9780470499832... the 2012 version will be available soon.
