httpWebRequest

Guys

I've just revised an app from 2003/CF2 to 2008/CF3.5 with a target platform of Pocked PC 2003 Device.

Pre the revision the webrequest worked fine but now I'm getting an error:-

System.net.WebException:The remote server returned an error: (404) Not Found.

However the file definately exists and can be seen from IE

HTML Code:

---

Dim ThisUri As New Uri(Buff)
Dim wr As HttpWebRequest = CType(WebRequest.Create(ThisUri), HttpWebRequest)
Dim ws As HttpWebResponse = CType(wr.GetResponse(), HttpWebResponse)
Dim str As Stream = ws.GetResponseStream()

Buff contains:-http://tah.openstreetmap.org/Tiles/tile.php/14/8028/5513.png
