Order by (doesnt works)

Question

Hi!

How can I filter by order? I do try this but its doesnt works properly:

string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\lunaoffice\lunaoffice\\app_data\office.mdb;Persist Security Info=False";

OleDbConnection sqlCon = new OleDbConnection(connectionString);

sqlCon.Open();

string commandString = "select * from stock order by N_O where code ='" + txtCode.Text + "'";

OleDbCommand sqlCmd = new OleDbCommand(commandString, sqlCon);

OleDbDataReader read = sqlCmd.ExecuteReader();

if (read.HasRows)

{

while (read.Read())

{

txtNumber.Text = read["number"].ToString();

txtProduct.Text = read["product"].ToString();

}

}

else

{

MessageBox.Show("This code " + txtCode.Text + " doenst exist");

}

read.Close();

sqlCon.Close();
