请教如何在应用程序中关闭或重新启动计算机？

用
ExitWindowsEx
下面是从msdn 上copy 下来的。在应用程序中关闭或重新启动计算机，这个函数已经绰绰有余了，但重新启动windows 还有许多工作要做。

The ExitWindowsEx function either logs off the current user, shuts down the system, or shuts down and restarts the system. It sends the WM_QUERYENDSESSION message to all applications to determine if they can be terminated.

BOOL ExitWindowsEx(
UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);

Parameters
uFlags
Specifies the type of shutdown. This parameter must include one of the following values: Value Meaning
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.

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.

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.



This parameter can optionally include the following values: Value Meaning
EWX_FORCE Forces processes to terminate. When this flag is set, the system does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency.
EWX_FORCEIFHUNG Windows NT 5.0 and later: Forces processes to terminate if they do not respond to the WM_QUERYENDSESSION or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.



dwReserved
Reserved; this parameter is ignored.
Return Values

那么多话，说用ExitWindowsEx(1,1)实现系统重启不就行了？不过此函数只能用于Win9X系统，NT无效。(2000我不知道，应该也不行吧）

[Firing_Sky]

NT 用 ExitWindows

哎，轮不到我了！

NT下需要SE_SHUTDOWN_NAME特权.需要先打开该特权才行.只有授权的用户才可以
SHUTDOWN.

[DragonCheng]

也可以用 InitiateSystemShutdown(NULL,NULL,0,TRUE,TRUE);

[csdn2000]

在程序中发布命令"rundll32.exe user.exe,exitwindows"。BTW,你可将
"rundll32.exe user.exe,exitwindows" 命令作为关机的快捷方式

关于在应用程序中关闭或启计算机，用ExitWindowEx可以在Win9x和NT，Win2000下实现！
下面告诉具体方法！
在Win9x下，可以直接用API ExitWindowEx函数就可以了，但对于NT，WIN2000就不行了，你得在View菜单中选择ClassWizard，然后在Message Maps中的Object IDS和Messages项中分别选择你的应用程序的窗口类，WM_CREATE.增加函数，内容如下：（我自己试了，运行良好！）
int CTimeSystemDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here
OSVERSIONINFO verinfo;
verinfo.dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
if(!::GetVersionEx(&verinfo))
{
AfxMessageBox("Get version Error!");
return -1;
}
if(verinfo.dwPlatformId==VER_PLATFORM_WIN32_NT)
{
HANDLE htoken;
DWORD retv;
TOKEN_PRIVILEGES tkp;
if(!::OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,&htoken))
{
AfxMessageBox("OpenProcessToken Error!");
return -1;
}
tkp.PrivilegeCount=1;
if(!LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&(tkp.Privileges[0].Luid)))
{
AfxMessageBox("Lookup Privilege Value Error");
return -1;
}
tkp.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
if(!AdjustTokenPrivileges(htoken,false,&tkp,sizeof(tkp),&tkp,&retv))
{
AfxMessageBox("");
return -1;
}
}
return 0;
}
