閉じるボタンを押すと、メッセージボックスがポップアップして、基本的には「本当に終了しますか?
これは私のコードです。
'Close Button
Private Sub BtnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnClose.Click
Dim result = MessageBox.Show(" Are you sure you want to quit", "Are you sure?", MessageBoxButtons.YesNoCancel)
Me.Close()
End Sub
Private Sub btnClose_Click(sender As Object, e As EventArgs) Handles btnClose.Click
If MsgBox("Are you sure you want to quit?", MsgBoxStyle.YesNo Or MsgBoxStyle.DefaultButton2, "Close application") = Windows.Forms.DialogResult.Yes Then
Me.Close()
End If
End Sub
