That code asks for ONLY one line to be added to the list box.

If you want multiple lines then you need to call Items.Add once for each string you want adding.

From what I can make out your result data is stored in a single string. you will need to split the string into an array, or loop your webclient call to fetch more results.

Hi, use this code

private void textBox_Leave(object sender, System.EventArgs e)
{
    listBox1.Items.Add(((TextBox)sender).Text);
}

try using this code :
private void button1_Click(object sender, EventArgs e)  
{  
      string url = "http://www.presscouncil.or.th/th2/index.php?option=com_content&view=article&id=230&Itemid=100084";  
      string result = null;  
      try  
      {  
           WebClient client = new WebClient();  
           result = client.DownloadString(url); 
           string[] lines = result.Split(new string[]{"\n"},StringSplitOptions.RemoveEmptyEntires);
           foreach(string line in lines)
           { 
                 listBox1.Items.Add(line);  
           }
      }  
      catch (Exception ex)  
      {

Sorry the correct code is as follows :
private void button1_Click(object sender, EventArgs e)
        {
            string url = "http://www.presscouncil.or.th/th2/index.php?option=com_content&view=article&id=230&Itemid=100084";
            string result = null;
            try
            {
                WebClient client = new WebClient();
                result = client.DownloadString(url);
                string[] lines = result.Split(new string[] { "\n" }, StringSplitOptions.RemoveEmptyEntries);
                foreach (string line in lines)
                {
                    listBox1.Items.Add(line);
                }
            }
            catch (Exception ex)
            {
                // handle error    
                MessageBox.Show(ex.Message);
            }
        }

I can understand the comment accepted.
The assist of mkobrin says in different words what I said, so I am surprised that gets an assist but my comment doesn't.

Of what use is the comment by samirbhogayta in resolving your problem?
