以服务的方式,动态加载驱动

以后就是两个实现这两个功能的函数.

//=================================================================

//函数名:StopDriver

//功能:  暂停驱动

//参数:

//  IN strDriverName  驱动名

//  IN strServiceName 服务名

//返回值:

//  TRUE  成功

//  FALSE 失败

//=================================================================

BOOL StopDriver(IN LPCSTR strDriverName,

    IN LPCSTR strServiceName)

{

 SC_HANDLE hMangerHandle = NULL;

 SC_HANDLE hCreateServiceHandle = NULL;

 SC_HANDLE hOpenServiceHandle = NULL;

 SERVICE_STATUS sStatus ;

 DWORD dwErrCode = 0;

 BOOL bRet = TRUE;

 do 

 {

  //1.打开服务控制管理器

  hMangerHandle = ::OpenSCManager(NULL,

   NULL,

   SC_MANAGER_ALL_ACCESS);

  if(!hMangerHandle)

  {

   bRet = FALSE;

   break;

  }

  //2. 打开service

  hOpenServiceHandle = OpenService(hMangerHandle, strServiceName,

   SERVICE_START | DELETE | SERVICE_STOP);

  if (!hOpenServiceHandle)

  {

   dwErrCode = ::GetLastError();

   bRet = FALSE;

   break;

  }

  //4.启动服务程序

  bRet = ControlService(hOpenServiceHandle, SERVICE_CONTROL_STOP, &sStatus);

  if (!bRet)

  {

   bRet = FALSE;

   break;

  }

  //删除服务

  bRet = DeleteService(hOpenServiceHandle);

 } while (0);

 }

 return bRet;

}

//加载驱动

//=================================================================

//函数名:StartDriver

//功能:  以服务的方式启动驱动

//参数:

//  IN strDriverName  驱动名

//  IN strServiceName 服务名

//  IN strDriverFilePath  文件路径

//返回值:

//  TRUE  成功

//  FALSE 失败

//=================================================================
