1. Give your variables meaningful names. At a glance, what does textBox1 do?
2. Your code is wide open to a SQL Injection attack. You need to look into using parameterised queries here.
3. Your insert statement does nothing. You create the command text and then close the connection - you need to execute the command using cmd.ExecuteNonQuery();
4. You have no exception handling. What happens if you can't connect the database, for instance?
