红色"X"点击表格的处理程序 [英] Handler for Red 'X' Click on Forms

问题描述

有人知道一种简单的方法来处理红色"X"(位于右上角)单击事件吗?我做了一些研究，但是到目前为止，我发现所有用户诱发"表单都可以使用的解决方案(例如，包括按下已添加到表单的按钮). 有没有办法只处理窗口红色"x"点击?谢谢.

Does anyone know of an easy way to handle the red 'X' (in top right corner) click event? I done a bit of research, but solutions I have found so far work for all 'user-induced' form closes (eg, including pressing a button that has been added to the form). Is there a way to handle only a window red 'x' click? Thanks. 

推荐答案

看看表单关闭事件，您可以使用e参数，例如

Look at Form Closing event, you can work with e parameter e.g.

e.Cancel = true或e，Cancel = false，具体取决于您要执行的操作

e.Cancel = true or e,Cancel = false depending on what you want to do

Imports System.ComponentModel

Public Class Form1
    Private Sub Form1_Closing(sender As Object, e As CancelEventArgs) Handles Me.Closing
        If MessageBox.Show("Exit", "Question", MessageBoxButtons.YesNo) = DialogResult.Yes Then
            ' they decided to exit so let them
        Else
            e.Cancel = True
        End If
    End Sub
End Class
