一个小问题～！～！～！～！～！～！～！

在使用user32.dll里面的Api函数 ExitWindowsEx 时 出现了一点小问题。
代码如下：
[ DllImport("user32") ]
public static extern long ExitWindowsEx(long uFlags, long dwReserved ) ;

public static void ShoutDownWindows() //关机
{
ExitWindowsEx(1,dwReserved);
}
public static void ReBootWindows() //重启
{
ExitWindowsEx(2,dwReserved);
}
public static void LogOffWindows() //注消
{
ExitWindowsEx(0,dwReserved);
}

其中”注消“可以 但是关机，和重启，就没有什么反应。这是为什么？
操作系统：Windows2000 Server
以Administrator用启运行！

那位大哥请指点一下！

把“关机，和重启”下面的代码换成“注销”下面的代码，试试会是什么效果，然后把注销下面的代码换成“关机，和重启”，再试试，又是什么效果。

我是不太记得了哦。我记得以前用VB写惯技代码的时候，好象有个操作系统还是什么情况下还要多加什么才能做到关机的，具体忘掉了，看看有人知道不。。

查一下：ExitWindowsEx~~

[laZZe]

BOOL ExitWindowsEx(

UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);


Parameters

uFlags

Specifies the type of shutdown. This parameter must be some combination of the following values:

Value Meaning
EWX_FORCE Forces processes to terminate. When this flag is set, Windows does not send the messages WM_QUERYENDSESSION and WM_ENDSESSION to the applications currently running in the system. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency.
EWX_LOGOFF Shuts down all processes running in the security context of the process that called the ExitWindowsEx function. Then it logs the user off.
EWX_POWEROFF Shuts down the system and turns off the power. The system must support the power-off feature.Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.
EWX_REBOOT Shuts down the system and then restarts the system. Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.
EWX_SHUTDOWN Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped. Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.

这个是delphi中的~~~
