ExitWindowsEx只是退出windows,怎么才能退出的时候顺便关掉电源呢？

[general_cigarette]

ExitWindowsEx(EWX_SHUTDOWN, 0);
执行后，仅仅退出操作系统，而不能断电。

上面两位说的是在NT下用的
在Win98 WinMe下就用ExitWindowsEx(EWX_SHUTDOWN, 0);就可以了

如果要在98能用，在NT下能用则只用看一下
if (!OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
//一定是在98下！
ExitWindowEx(EWX_SHUTDOWN,0);
return;
}
...
..
做NT下的操作
..


使用上述代码后，您的机器电源没有关这可是个大问题
１。你机器的电源坏了
２。您用的的ＡＴ电源不是ＡＴＸ电源，不能软件关机

OSVERSIONINFO osvi;

osvi.dwOSVersionInfoSize = sizeof(osvi);
GetVersionEx(&osvi);

if (osvi.dwPlatformId == VER_PLATFORM_WIN32_NT)
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;

OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
&tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
(PTOKEN_PRIVILEGES)NULL, 0);

CloseHandle(hToken);
}

//ExitWindowsEx(EWX_REBOOT, 0); // reboot the computer
ExitWindowsEx(EWX_SHUTDOWN, 0); // shut down the computer
//ExitWindowsEx(EWX_POWEROFF, 0); // turn off the power
return 0;

这是我从csdn上拷贝的，就是不能关电源，但是我用操作系统关机的话，就能关电源。

ExitWindowsEx(EWX_SHUTDOWN|EWX_POWEROFF, 0);

呵呵，谢谢，应该用ewx_poweroff参数。

不好意思，上面是重起，把最后一句改成：ExitWindowsEx(EWX_SHUTDOWN, 0);
