Re: Cannot get GeoCode web service client to work.

Found some differences.

For the Delphi Soap application for the 'Transformer' tab I get



For my C# application I get


I can see the difference, but how do I turn of HTTP compression for my C# application?

More research, but if anyone has some answers before I google myself to death, please let me know.

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.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>

        <client>

                bindingConfiguration="GeoCode_Binding" contract="ServiceReference1.GeoCode_PortType"

        </client>

</configuration>


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).
