怎么Private Sub Form1_FormClosing中取消关闭窗体

如何Private Sub Form1_FormClosing中取消关闭窗体，
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing 
Dim myti As Integer myti = MsgBox("确定关闭此窗体", MsgBoxStyle.Question + MsgBoxStyle.YesNo, "提示") 
Select Case myti 
Case myti = MsgBoxResult.Yes e.Cancel = False 
End
Case myti = MsgBoxResult.No e.Cancel = True
End Select 
End Sub 
这个我实在网上搜的。好像是VS2005的。
我现在用的vs2008。想使用这种方法取消关闭窗体，但是没有e.Cancel = True 。请高手指教！

------解决方案--------------------
Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs)
If MessageBox.Show("是否现在关闭窗口", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) <> DialogResult.OK Then
e.Cancel = True
End If
End Sub
