Okay, so I just started using visual bsaic 2010. For my first project I am trying to build a web browser, i am using a tab control and all my buttons work on the original tab but once a make a new tab the buttons dont work

here is the home button code i am using
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate("http://www.google.com/search?q=" & TextBox2.Text)

it comes up saying index 0 is out of range any help would be appreciated
thanks
