To Send mail.

 Hi friends
I want to send the mail with the values which are  stored in database.
The Code which i used was
        da = new OdbcDataAdapter("SELECT comp_componentname, comp_color, comp_process FROM comp_details where comp_dcno='"+ txt4.Text +"' ", con);

        DataSet ds = new DataSet();

        da.Fill(ds, "comp_details");

        gdview.DataSource = ds;
        gdview.DataBind();

        con.Close();

        MailMessage msg = new MailMessage();
        msg.To = txt1.Text;
        msg.From = txt2.Text;
    &n ...
