download progress

[Jef Patat]

Hi guru's,

at the moment I made this simple application with only one textbox and one button. When the button is pressed a file is downloaded and displayed in the textbox.
Everything runs fine but I would like to display messages indicating what operation is currently taking place ie , connecting , requesting, receiving..etc so that one can identify at which stage the connection is. How can I do this?

this is the simple code in button1_click:

try
{
  WebClient client = new WebClient();
  Stream data = client.OpenRead("http://ichart.finance.yahoo.com/table.csv?s=MFE&d=6&e=9&f=2006&g=d&a=9&b=7&c=2005&ignore=.csv");  StreamReader reader = new StreamReader(data);
  string str = "";
  str = reader.ReadLine();

  while (str != null)
  {
    textBox1.AppendText(str + Environment.NewLine);
    textBox1.SelectionStart = textBox1.Text.Length;
    textBox1.ScrollToCaret();
    str = reader.ReadLine();
  }
  data.Close();
}
catch (WebException exp)
{
  MessageBox.Show(exp.Message, "Exception");
}

Thanks in advance
