我也想知道，帮你上去

可以对自动关机进行设置 要求现在倒计时方式关机 输入“Shutdown.exe -s -t 300”，这里表示5分钟后自动关机，“300”代表5分钟。 取消自动关机 设置好自动关机后，如果想取消，则在运行中输入“shutdown -a”

这个是关机其他的我就不晓得了 `~

5楼的忘记了一个东西！

那个原来是系统的东西 VB想用它必须 调用！

使用shell

shell "shoudown.exe -s -t 30"
表示30秒后关机

更详细的信息请百度搜索 关于shoudown的参数信息！


4楼的代码好象在XP 2000 下无效 还是98下的代码！

太棒了.顶~~~~~
我要的就是提高权限这一段
