Question

我目前正在学习如何在Visual Basic中编写命令，并决定制作一个简单的关机消息。代码完美无缺：用户点击“是”＆＃39;它关闭了，没有＆＃39;，＆＃39;取消＆＃39;而且＆＃39; X＆＃39;按钮关闭了消息。但是，我决定尝试制作一个恶作剧消息，计算机将关闭所选择的任何选项。我运行了脚本，但是当我点击“X＆＃39; icon（我不喜欢关闭我的计算机的想法！），我的计算机关机无论如何:( 有没有办法阻止这种情况发生，或者更好的是，有没有办法让“X＆＃39;图标，以便用户无法关闭消息？这是代码：

Option Explicit
Dim result
result = MsgBox ("Do you want to shutdown?", 3+48,"Warning")
Dim objShell
Select Case result
    Case vbYes
        MsgBox("shuting down ...")
        Set objShell = WScript.CreateObject("WScript.Shell")
        objShell.Run "C:\WINDOWS\system32\shutdown.exe -r -t 20"
    Case vbNo
        MsgBox("shuting down ...")
        Set objShell = WScript.CreateObject("WScript.Shell")
        objShell.Run "C:\WINDOWS\system32\shutdown.exe -r -t 20"
    Case vbCancel
        MsgBox("shuting down ...")
        Set objShell = WScript.CreateObject("WScript.Shell")
        objShell.Run "C:\WINDOWS\system32\shutdown.exe -r -t 20"
End Select

提前干杯！：d

Answer 2

好的，是否有理由尝试删除/禁用X？我问，因为虽然可以做到，但有点困难。

并非所有msgbox上的按钮组合都启用X.尝试vbAbortRetryIgnore并尝试使用vbYesNo。
如果提供了取消按钮（除了vbOkOnly之外的所有其他组合），则启用X
如果只显示一个按钮，则启用X

一旦你意识到这些事情，这确实使得禁用按钮几乎毫无意义。以下是当用户点击X与点击按钮

N / A。 X按钮未启用
MsgBox返回vbCancel
MsgBox仅返回按钮的值顺便说一下，它不只是单击X.当启用X时，ESC将触发相同的结果。
