OpenFileDialog弹两次窗口

Dim FileOpen As OpenFileDialog
Dim result As DialogResult

result = FileOpen.ShowDialog

If result = DialogResult.Cancel Then
  …………
End If

以这样判断是否按下“取消”，会导致弹两次文件打开窗口。求教正常弹一次的方法。 OpenFileDialog
[解决办法]
If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
...
End If
