            MySqlConnection MyConn2 = new MySqlConnection(conn);
            MySqlCommand MyCommand2 = new MySqlCommand(Query, MyConn2);
            MySqlDataReader MyReader2;
            MyConn2.Open();
            MyReader2 = MyCommand2.ExecuteReader();
            MessageBox.Show("Data Saved");
            while (MyReader2.Read())
                MyConn2.Close();

        }
