    int port = 8080;

    try
    {
        // Get the current configuration file.
        System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

        // Get the MyUrls section.
        UrlsSection myUrls =
           config.Sections["MyUrls"] as UrlsSection;

        // Create the new  element.
        UrlConfigElement newElement =
            new UrlConfigElement(name, url, port);

        // Set its lock.
        newElement.LockItem = true;

        // Save the new element to the 
        // configuration file.
        if (!myUrls.ElementInformation.IsLocked)
        {

            myUrls.Urls.Add(newElement);

            config.Save(ConfigurationSaveMode.Full);
