Read XML response from a webservice

Oct 13th, 2009

Hi, I've tried to get the geolocation of the clients IP, with this code:

 Help with Code Tags 
 vb Syntax (Toggle Plain Text) 
Dim rssReq As System.Net.WebRequest = _
System.Net.WebRequest.Create("http://freegeoip.appspot.com/xml/" _
& vl_bContadorVisitasBE.vcConVisIP)
 
'Crear el Proxy
Dim px As New System.Net.WebProxy("http://freegeoip.appspot.com/xml/" _
& vl_bContadorVisitasBE.vcConVisIP, True)
 
'Asignar el Proxy al objeto WebRequest
rssReq.Proxy = px
 
'Establecer el tiempo de vida al objeto WebRequest
rssReq.Timeout = 2000
 
Try
'Obtener el objeto WebResponse
Dim rep As System.Net.WebResponse = rssReq.GetResponse()              [COLOR="Red"]<-- ERROR[/COLOR]
 
'Insertar el objeto Response en el objeto XMLTextReader
Dim xtr As New System.Xml.XmlTextReader(rep.GetResponseStream())
 
'Insertar el objeto Response en el objeto DataSet
ds.ReadXml(xtr)
 
Catch ex As Exception
 
End Try
Dim rssReq As System.Net.WebRequest = _
System.Net.WebRequest.Create("http://freegeoip.appspot.com/xml/" _
& vl_bContadorVisitasBE.vcConVisIP)

'Crear el Proxy
Dim px As New System.Net.WebProxy("http://freegeoip.appspot.com/xml/" _
& vl_bContadorVisitasBE.vcConVisIP, True)

'Asignar el Proxy al objeto WebRequest
rssReq.Proxy = px

'Establecer el tiempo de vida al objeto WebRequest
rssReq.Timeout = 2000

Try
'Obtener el objeto WebResponse
Dim rep As System.Net.WebResponse = rssReq.GetResponse()              [COLOR="Red"]<-- ERROR[/COLOR]

'Insertar el objeto Response en el objeto XMLTextReader
Dim xtr As New System.Xml.XmlTextReader(rep.GetResponseStream())

'Insertar el objeto Response en el objeto DataSet
ds.ReadXml(xtr)

Catch ex As Exception

End Try

But I keep getting the error "The underlying connection was closed: An unexpected error occurred on a receive." when executes the GetResponse line.

I tried to get better methods to do the same, but no luck.

The XML returned by the WS (http://freegeoip.appspot.com/xml/200.62.145.200) is something like this:
