C++实现远程关机

记得刚学C++的时候,喜欢研究API,当时同事有一个高手,写了段代码,我在写程序的时候,莫明妙的,机器突然关掉了!我正在纳闷的时候,我听到了他的奸笑!   原来是他干的,后来我研究了好久InitiateSystemShutdown这个API函数,了解被作弄的原理了,因为我的机器加入了Windows的域,而且域的超级用户我也设置成对我本机有Administrator权限,所以,他才有机可乘!后来写了以下这段代码,让他也在工作的时候被我远程关机,爽啊!学了新东西,又以其人之道还施彼身!
   //ShutDownSystem函数是关本地,自己的机器   
BOOL CAlarmClockDlg::ShutDownSystem()    {    HANDLE hToken;    TOKEN_PRIVILEGES tkp;    // Get a token for this process.    if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))    AfxMessageBox("OpenProcessToken");    // Get the LUID for the shutdown privilege.    LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid);    tkp.PrivilegeCount = 1; // one privilege to set    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;    // Get the shutdown privilege for this process.    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES)NULL, 0);    if(GetLastError()!= ERROR_SUCCESS)    AfxMessageBox("AdjustTokenPrivileges");    // Shut down the system and force all applications to close.    if(!ExitWindowsEx(EWX_SHUTDOWN|EWX_FORCE, 0))    {    return FALSE;    }    else    {    return TRUE;    }    }    //shutdownHost这个就是远程关机的C++函数了!hostName可以是机器IP,也可以是机器名字!    BOOL CAlarmClockDlg::shutdownHost(CString hostName)    {    HANDLE hToken; // handle to process token    TOKEN_PRIVILEGES tkp; // pointer to token structure    BOOL fResult; // system shutdown flag    // Get the current process token handle so we can get shutdown    // privilege.    if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))    AfxMessageBox("OpenProcessToken failed.");    // Get the LUID for shutdown privilege.    LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);    tkp.PrivilegeCount = 1; // one privilege to set    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;    // Get shutdown privilege for this process.    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES) NULL, 0);    // Cannot test the return value of AdjustTokenPrivileges.    if (GetLastError() != ERROR_SUCCESS)    AfxMessageBox("AdjustTokenPrivileges enable failed.");    // Display the shutdown dialog box and start the time-out countdown.    fResult = InitiateSystemShutdown("192.168.100.245", // shut down local computer    "Click on the main window and press the Escape key to cancel shutdown.", // message to user    1, // time-out period    FALSE, // ask user to close apps //注意这一段API调用!    FALSE); // reboot after shutdown    if (!fResult)    {    AfxMessageBox("InitiateSystemShutdown failed.");    }    // Disable shutdown privilege.    tkp.Privileges[0].Attributes = 0;    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES) NULL, 0);    if (GetLastError() != ERROR_SUCCESS)    {    AfxMessageBox("AdjustTokenPrivileges disable failed.");    }    return TRUE;    }
