ID per timer

[Duquan]

Hey, everybody, I got a problem. I've finally been able to make a website transition mechanism, but now there's a problem how a function can be called, for example, every 10 seconds. I've been in a timer, there's no effect. This is the code I was trying to put in the timer:

    private void timer2_Tick(object sender, EventArgs e)
    {
        timer++;
    MySqlConnection cnt = new MySqlConnection(strProvider);
    try
    {
        cnt.Open();
        MySqlCommand cmd3 = cnt.CreateCommand();

        cmd3.CommandText = "SELECT * FROM t_links WHERE ID = '" + timer + "'";
        MySqlDataReader readURL = cmd3.ExecuteReader();
        while (readURL.Read())
        {
            URL = readURL["URL"].ToString();
            webBrowser1.Navigate(URL);
            labelUrl.Text = "URL: " + URL;
        }
        readURL.Close();
    }
    finally     
    {
        cnt.Close();
    }
}

WHERE ID = '" + timer + "'";

Try that.

WHERE ID = " + timer;
