記得剛學(xué)C++的時候,喜歡研究API,當(dāng)時同事有一個高手,寫了段代碼,我在寫程序的時候,莫明妙的,機(jī)器突然關(guān)掉了!我正在納悶的時候,我聽到了他的奸笑!
原來是他干的,后來我研究了好久InitiateSystemShutdown這個API函數(shù),了解被作弄的原理了,因?yàn)槲业臋C(jī)器加入了Windows的域,而且域的超級用戶我也設(shè)置成對我本機(jī)有Administrator權(quán)限,所以,他才有機(jī)可乘!后來寫了以下這段代碼,讓他也在工作的時候被我遠(yuǎn)程關(guān)機(jī),爽啊!學(xué)了新東西,又以其人之道還施彼身!
//ShutDownSystem函數(shù)是關(guān)本地,自己的機(jī)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這個就是遠(yuǎn)程關(guān)機(jī)的C++函數(shù)了!hostName可以是機(jī)器IP,也可以是機(jī)器名字!
