修改系统服务的启动类型并启动服务

有时可能需要手动修改系统服务或者我们自己写的服务的启动类型，并手动将服务启动起来，这些手动操作均可以通过代码实现。要实现这样的操作，需要用到下列函数：OpenSCManager、OpenService、ChangeServiceConfig、StartService、CloseServiceHandle，函数的具体说明和用法查看MSDN即可。对于下图，注意调用API函数时，要使用服务名称，不能使用显示名称。

下面给出将服务设置为自动启动，并将服务启动起来的相关代码：

    BOOL ChangeServiceStartTypeAndStart( CString strSvrName )      {          SC_HANDLE schSCManager;          SC_HANDLE schService;                // Get a handle to the SCM database.           CString strErrInfo;                schSCManager = OpenSCManager(               NULL,                    // local computer              NULL,                    // ServicesActive database               SC_MANAGER_ALL_ACCESS);  // full access rights                 if (NULL == schSCManager)           {              strErrInfo.Format(_T("OpenSCManager failed (%d)\n"), GetLastError());              AfxMessageBox(strErrInfo);              return FALSE;          }                // Get a handle to the service.          schService = OpenService(               schSCManager,            // SCM database               (LPCTSTR)strSvrName,               // name of service               SERVICE_CHANGE_CONFIG|SERVICE_START);  // need change config access                 if (schService == NULL)          {               strErrInfo.Format(_T("OpenService failed (%d)\n"), GetLastError());               AfxMessageBox(strErrInfo);              CloseServiceHandle(schSCManager);              return FALSE;          }                    // Change the service start type.(set to auto start type)          BOOL bRet = ChangeServiceConfig(               schService,        // handle of service               SERVICE_NO_CHANGE, // service type: no change               SERVICE_AUTO_START,  // service start type     --  将服务的启动类型设置为自动启动            SERVICE_NO_CHANGE, // error control: no change               NULL,              // binary path: no change               NULL,              // load order group: no change               NULL,              // tag ID: no change               NULL,              // dependencies: no change               NULL,              // account name: no change               NULL,              // password: no change               NULL);          if ( !bRet )            // display name: no change          {              strErrInfo.Format(_T("ChangeServiceConfig failed (%d)\n"), GetLastError());               AfxMessageBox(strErrInfo);              CloseServiceHandle(schService);               CloseServiceHandle(schSCManager);              return FALSE;          }          else           {              strErrInfo.Format(_T("Service disabled successfully.\n"));           }                // Start the service  -- 启动该服务        bRet = StartService(              schService,  // handle to service               0,           // number of arguments               NULL);          // Attempt to start the service.          if ( !bRet )      // no arguments           {              strErrInfo.Format(_T("StartService failed (%d)\n"), GetLastError());              AfxMessageBox(strErrInfo);          }          else           {              printf("Service start pending...\n");           }                // Close service handles          CloseServiceHandle(schService);           CloseServiceHandle(schSCManager);                return bRet;      }
