// a user defined class derived from LInet should be used to support the OnDataStart callback function
// suppose it was named as LUserInetODStart
class LUserInetODStart : public LInet

protected:
   virtual L_INT OnDataStart(LInet plConnection, L_INT nError);
};

{
   L_INT             nRet;
   LUserInetODStart  UserInet;
   // connect to LEAD
   nRet = UserInet.Connect("207.238.49.190", 1000);
   if(nRet != SUCCESS)
      return nRet;
   return SUCCESS;
