Thanks I give that a go. Used fiddler for web sites not web services.
Haven't use it for a while so another thing to relearn.
Regards Peter.

Have you had a look at whats happening using Fiddler? (or other
suitable traffic monitoring tool)
Might give you a hint as to whats being sent/returned. might even show
you an error rather than just empty result

I am re-learning WCF and am trying a simple web service client to the US Geo
Coordinate service at http://geocoder.us/
WSDL is at http://rpc.geocoder.us/dist/eg/clients/GeoCoder.wsdl
There is a C# Client at
http://www.c-sharpcorner.com/uploadfile/scottlysle/geocoderuswebservice01232008035119am/geocoderuswebservice.aspx
but it does not work. It keeps saying that the address given is invalid.
I have used the sample addresses at http://geocoder.us/ and while they work
in the web site they don't in the c# demo.
I have a demo Delphi application that also works against this site.
So the site is working!!
I wrote a extremely basic web service client. I added a service reference
using the WSDL and created a simple winForm application
Code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.ServiceModel;
using GeoCodeTest.ServiceReference1;
namespace GeoCodeTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private GeocoderResult[] LocationResult = null;
private GeoCode_PortTypeClient proxy = null;
private void btnGo_Click(object sender, EventArgs e)
{
LocationResult = proxy.geocode(txtLocation.Text); // always
returns a null !!!
geocoderResultBindingSource.DataSource = LocationResult;
}
private void Form1_Load(object sender, EventArgs e)
{
proxy = new GeoCode_PortTypeClient("GeoCode_Port");
}
}
}
No matter what address I put in, the result returned is always null.
In the C# demo from
http://www.c-sharpcorner.com/uploadfile/scottlysle/geocoderuswebservice01232008035119am/geocoderuswebservice.aspx
the location returned was also null.
This is the app.config file that was generated.

There is a link to passing credentials here to fix an issue
http://geocoder.us/help/msxml.shtml.
But I don't think that has anything to do with this (could be wrong). I am
using the free service.
Can anyone tell me why the C# solution won't work where as other solutions
do?
Is there something else one needs to do (apart from tearing one's hair out).
Regards Peter
