* Inserts a new row (value number greater than max rows)
* Displays row values

[CODE]


            string connString = "Server=localhost;Database=cshptest;Uid=root;"; // Select DB
            MySqlConnection conn = new MySqlConnection(connString);
            MySqlCommand command = conn.CreateCommand();
            // Command to count the rows
            conn.Open();
            command.CommandText = "SELECT COUNT(*) FROM csdat";
            int rows = Convert.ToInt32(command.ExecuteScalar());
            int newrows = rows + 1;
            conn.Close();
            // Insert a new data row, with the value greater than last index value (ex. 5 + 1 = 6)
            command.CommandText = "Insert into csdat (id,dataT) values('" + newrows + "','" + newrows + "');";
            conn.Open();
            command.ExecuteNonQuery();
            conn.Close();
            MySqlDataReader reader;
            // Read data in each row
