C# event problem...

Cantab.

Hi guys, I'm trying to raise an event once the "\n" character is seen on the response stream...

When the page www.asdf.com/test.php is accessed, it spits out the following (each line takes 5 seconds to appear)
Hello Master 1<br>\n
Hello Master 2<br>\n
Hello Master 3<br>\n

hwrq = (HttpWebRequest)WebRequest.Create("http://www.asdf.com/test.php");
hwrs = (HttpWebResponse)hwrq.GetResponse();

Stream rs = hwrs.GetResponseStream();
StreamReader sr = new StreamReader(rs, Encoding.UTF8);
string line;

while ((line = sr.ReadLine()) != null)
{
     label1.Text="new-line char found!";
}
rs.Close();
sr.Close();

Any ideas would be much appreciated. Is there such thing as a buffer event? Or an event that's raised when a certain character enters a buffer?

Cantab.

Howdy chaps,

I think I've figured it out...

A simple case of sending lines ending with "\r\n" instead of "\n"!

Hello Master 1<br>\r\n
Hello Master 2<br>\r\n
Hello Master 3<br>\r\n

HTTP protocol requires that lines end with a carriage return followed by a new line...

There ya go...

private void examine_stream()
{
   try
   {
      hwrq=(HttpWebRequest)WebRequest.Create("http://www.asdf.com/test.php");
      hwrs = (HttpWebResponse)hwrq.GetResponse();

      Stream rs = hwrs.GetResponseStream();
      StreamReader sr = new StreamReader(rs, Encoding.UTF8);

      string line;
      while ((line = sr.ReadLine()) != null)
      {
         label1.text=line;
      }            
      rs.Close();
      sr.Close();
   }
   catch(etc...
}

I'd welcome any comments about this bit of code:

while ((line = sr.ReadLine()) != null)
{
   label1.text=line;
}

Is that while loop gonna be polling continuously? How can I make this more efficient? (btw, the function examine_stream() runs in its own thread)
