Everything seems OK when I looked over it except, of course, you aren't actually inserting the data into the database. After setting the command text you need to include the line:
cmd.ExecuteNonQuery();
This is the command that places the data into the database. Also,you shouldn't enter the text provided by the user directly into the SQL statement. It allows for hacking attacks via SQL injection (read up on it - its useful to know about). Use parametized queries to avoid the problem.

Yes cmd.ExecuteNonQuery(); is missing.
Why cant you write SP for this? and just pass the parameters?

[Netcode]

use the cmd.ExecuteNonQuery() just after your insert statement
