public string ReturnTitle(string strurl)
{
  string strResult="";
  try
  {
   System.Net.HttpWebRequest myReq=(HttpWebRequest)HttpWebRequest.Create(strUrl);
   myReq.Timeout=timeout;
  System.Net.HttpWebResponse  myResp=(HttpWebResponse)myReq.GetResponse();
  System.IO.Stream myStream=myResp.GetResponseStream();
  System.IO.StreamReader sr=new StreamReader(myStream,System.Text.Encoding.Default);
  System.Text.StringBuilder sb=new StringBuilder();
  while(-1!=sr.Peek())
 {
    sb.Append(sr.ReadLine()+"\r\n");
 }
 sb=sb.Replace("<TITLE>","<title>");
 sb=sb.Replace("</TITLE>","</title>");
sb=sb.Replace("<TITLE>","<title>");
sb=sb.Replace("</TITLE>","</title>");
strResult=sb.ToString();
int beg_num=0;
int end_num=0;
beg_num=strResult.IndexOf("<title>");
end_num=strResult.IndexOf("</title>");
eg_num+=7;
strResult=strResult.Substring(beg_num,end_num-beg_num);
}
catch(System.Exception Ex)
{
  strResult="Error:"+Ex.Message;
}
return strResult;
}
