            {
                ThreadingTimer timer = new ThreadingTimer(new TimerCallback(TimerAction), dataValue, 0, 2000);
            }

        }

void TimerAction(object flag)
{

           flags_string = flag.ToString();
            string sql = "SELECT msisdn,sms FROM sms_data_bankasia where flag = " + flags_string + " LIMIT 1";
            MySqlCommand comd = mycon.CreateCommand();
            comd.CommandText = sql;
            MySqlDataReader dtr = comd.ExecuteReader();
            try
            {
                if (mycon.State == ConnectionState.Open)
                {

                    if (dtr.Read())
                    {

            }

            dtr.Close();

            string[] listitem ={ msisdn_string, sms_string, flags_string };
            ListViewItem li = new ListViewItem(listitem);
