    private void timer1_Tick(object sender, System.EventArgs e)
        {

            label1.SetBounds(x, y, 1, 1);
            x++;
            if(x>=800)

Code for reading xml

private void StartRssThread()
        {
            List<RssChannel> channels = new List<RssChannel>();
            StringBuilder mergedFeed =  new StringBuilder();
            int mh = 0;


                int ms = 0;
                if (mh < 7)
                {
                    RssFeed DaFeed = RssFeed.Read("http://shjc.ae/rss/fileName.xml");
                    RssChannel DaChannel = (RssChannel)DaFeed.Channels[0];
                    channels.Add(DaChannel);
                    mergedFeed.AppendFormat(" {0}: ", DaChannel.Title);

                    foreach (RssItem sTrm in DaChannel.Items)
                    {
                        if (ms < 10)
                        {
                            mergedFeed.AppendFormat(" {0} |", sTrm.Title);
                            ms++;
                            mh++;
                        }
                    }
                }

            string dafeed = mergedFeed.ToString();
            mergedFeed = null;
            textBox1.Invoke(new UpdateUiCallback(this.UpdateUi), new string[] { dafeed });

        }
Solution

  • You are using hard coded values for the start and max value of x. From your question I think the text in the label has a dynamic length (correct?). If the text is of dynamic length the value of x should also be dynamic.

    Also, x starts at -800. Then slowly grows to 800 and then it gets set to 4. This seems strange to me, if the first run started at -800, the second run may also need to start at -800.

    Hope this somewhat helped you. If not, please provide more details (like why you chose -800, 800 and 4).
