在MFC中怎么通过点击一个按钮重启计算机

[lsxsxs]

有没有一种方法，点击了一个按钮之后就让计算机重启。要在按钮事件中添加什么代码啊。我加了个
ExitWindowsEx(EWX_REBOOT, 0)或者 ExitWindowsEx(EWX_REBOOT, EWX_FORCE)都不行，只是在我关闭生成的窗口之后把我的VS2008给关了。

[lsxsxs]

我在网上看了一下，我那个之所以不行，是因为那个API只是在Win9X下有用，不过一楼的兄弟，
int nResult = RtlAdjustPrivilege(SE_SHUTDOWN_PRIVILEGE, true, true, &nEn);
这句话报异常，是怎么回事呢

[zgl7903]

UINT FFlag = EWX_SHUTDOWN | EWX_POWEROFF | EWX_FORCE;

// Get version info to determine operation
OSVERSIONINFO osvi;
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
if (GetVersionEx(&osvi))
{
	// Determine the platform
	if (osvi.dwPlatformId == VER_PLATFORM_WIN32_NT)
	{
		HANDLE hToken;
		TOKEN_PRIVILEGES tkp;
		
		// Windows NT 3.51, Windows NT 4.0, Windows 2000,
		// Windows XP, or Windows .NET Server
		if (OpenProcessToken(GetCurrentProcess(),
		TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
		{
			LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);
			
			tkp.PrivilegeCount = 1;  // one privilege to set
			tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
			
			AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
		}
	}
}

ExitWindowsEx(FFlag, 0);

不好意思 刚才那个是关机
用UINT FFlag = EWX_REBOOT | EWX_FORCE;

之前也碰到过权限的问题，同样想了解，帮顶。。。

顶6楼

[你妹的特盗不]

直接执行系统命令 shutdown -r -t 0
马上系统就重启了

[SullenSun]

void CShutRebootDlg::OnShutdown()
{
// TODO: Add your control notification handler code here
int nvalue= AfxMessageBox("是否真的要关闭计算机？",4+32+256);
if(nvalue==IDYES) //用户按下了"是"按钮
{
OSVERSIONINFO osv;
osv.dwOSVersionInfoSize = sizeof OSVERSIONINFO;
GetVersionEx(&osv);//获取操作系统的版本
if(VER_PLATFORM_WIN32_NT == osv.dwPlatformId)
{
// 如果运行在NT/XP平台，必须先取得权限
HANDLE hProcess, hToken;
TOKEN_PRIVILEGES Privileges;
LUID luid;
hProcess=GetCurrentProcess();
OpenProcessToken(hProcess, TOKEN_ADJUST_PRIVILEGES, &hToken);
Privileges.PrivilegeCount = 1;
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &luid);
Privileges.Privileges[0].Luid = luid;
Privileges.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &Privileges, NULL, NULL, NULL);
}
ExitWindowsEx(EWX_SHUTDOWN,0);//关闭计算机
}

完整的重启方法，我自己就是这样做的，没问题。
