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
