将
Option Explicit
取消看看??

[RyuOut]

AdjustTokenPrivilegesForNT

这句话是没有意义的

[djfdd]

陈老师，还是我的问题啊，上面的代码也是你教我的，我取消了，现在报错为＇Timer1.Enabled = False　，要求对象＇

[online]

你的form上有没有timer控件？？？？

[华芸智森]

这说明你的窗体中没有Timer1控件.

[华芸智森]

如果是这样.你从左边的工具箱中拖一个时钟控件到FORM中即可.

[djfdd]

我做了，现在只能注销，不能关机，几个参数我都试了，为什么？？／

我也遇到这样的问题,只能够注销XP,并不能关闭他!

其实用不着那么麻烦，就是因为一个EMX_POWEROFF=8，这个常数msdn里没有
