  Hi,

  Instead of loading the data directly, create a WebClient and see if it gets the stream, and try to debug from there...

  try

  {

  XmlDataDocument doc = new XmlDataDocument();

  System.Net.WebClient wc = new System.Net.WebClient();

  Stream instream = wc.OpenRead("http://reviews.cnet.com/4534-10921_7-0.xml");

  doc.Load(instream);

  doc.WriteContentTo(new XmlTextWriter(Console.Out));

  }

  catch (System.Net.WebException wex)

  {

  Console.WriteLine(wex.ToString());

  }

  It still does not work no matter how i try.

  Hi,

  Instead of loading the data directly, create a WebClient and see if it gets the stream, and try to debug from there...

  try

  {

  XmlDataDocument doc = new XmlDataDocument();

  System.Net.WebClient wc = new System.Net.WebClient();

  Stream instream = wc.OpenRead("http://reviews.cnet.com/4534-10921_7-0.xml");

  doc.WriteContentTo(new XmlTextWriter(Console.Out));

  }

  catch (System.Net.WebException wex)

  {

  Console.WriteLine(wex.ToString());

  }

  I tried to use this set of codes but i notice that it is in java or csharp not vb. So i do not know what is Stream instream in vb.

  Next i also tried other ways your say like XmlDocument it stills give me the same problem too. I have no ideas left pls help.

  Below are the codes i have tried.

  Public Sub getHeaderList2(ByVal strUrl As String)

  Dim reader As New XmlTextReader("http://reviews.cnet.com/4534-10921_7-0.xml")

  Dim ds As DataSet = New DataSet

  ds.ReadXml(reader)

  End Sub

  Public Sub getHeaderList1(ByVal strUrl As String)

  Try

  Dim doc As New XmlDataDocument

  Dim wc As New System.Net.WebClient

  doc.Load(wc.OpenRead("http://reviews.cnet.com/4534-10921_7-0.xml"))

  doc.WriteContentTo(New XmlTextWriter(Console.Out))

  Catch wex As System.Net.WebException

  Console.WriteLine(wex.ToString())

  End Try

  End Sub

  Public Sub getHeaderList(ByVal strUrl As String)

  Dim doc As New XmlDataDocument

  doc.Load(strUrl)

  Dim root As XmlElement

  root = doc.DocumentElement

  Dim m_nodeRoot As XmlNodeList

  m_nodeRoot = doc.SelectNodes("/rss/channel")

  Dim itemNode As XmlNodeList

  itemNode = doc.SelectNodes("/rss/channel/item")

  Dim count As Integer

  For Each item As XmlNode In itemNode

  count = count + 1

  addnewHeader_headerList(item.SelectSingleNode("title").InnerText, count)

  Next

  End Sub

  Please help me!!!

  At least now we know that your problem has nothing to do with XML and document load method.

  This is the error i got using webclient:

  System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive.

  at System.Net.HttpWebRequest.CheckFinalStatus()

  at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)

  at System.Net.HttpWebRequest.GetResponse()

  at System.Net.WebClient.OpenRead(String address)

  at RSSReader.Form1.getHeaderList1(String strUrl) in C:\Inetpub\wwwroot\RSSReader\Form1.vb:line 403

  One more thing:

  Some sites have DDOS protection. When you are testing the code you may overload the server with your requests and it can block you for some time. try some other rss sources.

  As my original post stated the exception is a network error.

  If you don't use DataSet you don't need XmlDataDocument.

  Consider using XmlDocument or XPathDocument instead.

  I should have done this a few days ago. heh
  
  Public Function GetRssFeed(ByVal path As String) As Xml.XmlDocument
  Dim TmpUrl As String = path
  Dim TmpRequest As Net.WebRequest = Net.WebRequest.Create(TmpUrl)
  Dim TmpResponse As Net.WebResponse = TmpRequest.GetResponse()
  Dim TmpReader As New IO.StreamReader(TmpResponse.GetResponseStream(), System.Text.Encoding.ASCII)
  Dim TmpContent As String = TmpReader.ReadToEnd()
  Dim TmpXml As New Xml.XmlDocument
  TmpXml.LoadXml(TmpContent)
  GetRssFeed = TmpXml
  End Function
  
  Try that function. It's easy to use and can be used as such.
  
  MsgBox(GetRssFeed("http://reviews.cnet.com/4534-10921_7-0.xml").InnerXml)
  
  The function returns an XmlDocument. In this example i'm simply outputting it for purposes.

  The exception happens a few seconds after i press the button that retreives the update.

  As for my internet connection speed it should be fast enough. But as for my house, i do have a router and i don't use any firewall except for the windows firewall.

  Please help me MarcD. Thanks a lot.

  So how any idea to help me
  

• sachin.pithode

  The exception is a networking exception which is occurring while trying to retrieve the document from the internet. When the exception happens does it happen right away or a few seconds after pressing the button that retreives the updates Are you on an extremely slow connection Doees your system have a firewall and have you configured your firewall to have access to it

  Have you tried other RSS feeds on the web Try creating a clean, new project that just reads the rss feed into a string.Don't copy paste anything, try to see where is the error that you could have done.
