如何在NT中实现中真正关机？

[Jockey]

以下是www.allapi.net 的示例，但它关机时候是不可以连电源关掉的，该如何呢？

ExitWindowsEx

VB声明
Declare Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long
说明
退出windows，并用特定的选项重新启动
返回值
Long，非零表示成功，零表示失败。会设置GetLastError
参数表
参数 类型及说明
uFlags Long，指定下述一个或多个标志（用OR运算符合并到一起）
EWX_FORCE 强迫中止没有响应的进程
EWX_LOGOFF 中止进程，然后注销
EWX_SHUTDOWN 关掉系统电源（如果可能的话，ATX电源就可以）
EWX_REBOOT 重新引导系统
EWX_SHUTDOWN 关闭系统
dwReserved Long，保留，设为零
注解
这个函数调用后会立刻返回，系统关闭过程是在后台进行的。注意先中止自己的应用程序，使关闭过程更显平顺。当然，您的进程必须有足够的优先权，否则也不能执行这种操作

关键问题在于你的机器是否支持ATX。

litsnake1(litsnake) 我和你的例子是一样的，你没有试过吗？

是不能关掉电源的!!!

////////////////////////////////////////////////

将：上面程序的常量定义部分的
Private Const EWX_POWEROFF = 8 '关掉系统电源
中的8改为5，6，8，7，9，10。。。。每一个都试一下。
保证有一个可以实现！
