Miles_LinYu你好
或者你可以 試試加入以下CODE
nn = Nothing
去 Clear 這個INSTANCE.
以下是我用來測試的CODE
Public nn As WebBrowser
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
nn = New WebBrowser
Me.Controls.Add(nn)
nn.Navigate("http://www.yahoo.com")
nn.Width = Me.Width - 50
nn.Height = Me.Height - 50
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
nn.Dispose()
Me.Controls.Remove(nn)
nn = Nothing '<---- clear instance
If Me.Controls("nn") IsNot Nothing Then
MsgBox("Still here")
Else
MsgBox("Gone")
End If
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If nn Is Nothing Then
MsgBox("empty")
Else
MsgBox("Still here")
End If
End Sub
Please forgive me if I mis-understood your questions.
