[VB.NET]一个简单的问题?

<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script>
一个简单的问题?
比如我有两个文本框 A,B
现在我在A文本框中输了东西,然后想敲一下回车,焦点转到B文本框中.
如何实现?
__________________________________________________________________________
在A的OnKeyDown事件里写

if e.KeyCode == Enter then
TextBoxB.Focus();
end if
__________________________________________________________________________
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then
TextBox2.Focus()
End If
End Sub

web 下要用js实现
