Your right, it is not necessary... when you provide a better description of what the problem is. But as everyone is having to guess how bad your code is, people are going to ask questions.

A database profiler is a tool which monitors a database and reports back when certain events occur, such as connections to the database, queries, triggers etc. SQL Server comes with its own profiler called (originally enough) SQL Server Profiler - I don't tend to use other databases but I'm sure there are similar tools available for other platforms.

It definitely isn't definatley

try... INSERT INTO mydb ([username],[password]) VALUES ('" + textBox1.Text + "','" + textBox2.Text + "') Also... - Confirm that 'mydb' is a table name and not the name of your database. - make sure your database columns have the corrent datatype - look into using parameters

do we use cmd.ExecuteNonQuery() for inserting??

Try changing your code to this:

SqlConnection con = connection();
SqlCommand cmd = new SqlCommand();
cmd.CommandText = query;
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
cmd.Dispose();

and see if you get an exception - if the insert has failed, the database should indicate this.

Yes that's fine. Broadly speaking, you use ExecuteNonQuery() to execute a SQL statement that doesn't return a result set, ExecuteQuery() to execute a statement that returns tabular data and ExecuteScalar() to execute a query which returns a single value (i.e. if you've done a count(*) or other scalar operation).
