How to get AppID ? I tried getting one from my yahoo login. Still my application does not work under the firewall. Can anybody explain me the usage of it under the firewall ?

Your question is hard to understand, could you try and rephrase it please?

Yes. I am trying to write a C# application using yahoo's webservices for Geocoding. I am giving an HttpWebRequest with the dummy AppId generated.

string url = "http://local.yahooapis.com/MapsService/V1/geocode?appid=35jF1DfV34HKjqV6hOQvXaXUv3Gui63U2_EAX44gFRylBAqLBDtDZK_KuG8qzcjYYkMZ&street=pune&city=Pune&state=India";
WebRequest req = HttpWebRequest.Create(url);
WebResponse res = req.GetResponse();

Now if I give the url in browser, it returns me the data but if I do it in application it is failing.
I am working on a PC which is firewalled under my company proxy.

And you think the firewaqll is maybe to blame.
Can you test your code outside of the firewall?

I am afraid, I cant test it outside firewall.

Ok so I knocked this together and it works for me.
So what is your actualy question - how to get this through the firewall?
Can you test my code too just to check it doesn't work  with your firewall - ie it's not a fault with yopur code.

Hello..
Thanks for your efforts.
I am getting an WebException - The underlying connection was closed: An unexpected error occurred on a receive. [This happens if I dont specfy the proxy]

If I specify proxy using the call as shown below
WebRequest req = HttpWebRequest.Create(url);
req.Proxy = new WebProxy("---- my proxy------ ", false, new string[0]);
then I get WebException as - The remote server returned an error: (404) Not Found.

Can we conclude on something with this result. Since I am new to C# coding I am not able to figure out the problem.

Ok this is a bit of a guess but try this:

req.Proxy = WebRequest.DefaultWebProxy;
So we have...
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
namespace YahooTest
{
class Program
{
static void Main(string[] args)
{
string url = "http://local.yahooapis.com/MapsService/V1/geocode?appid=35jF1DfV34HKjqV6hOQvXaXUv3Gui63U2_EAX44gFRylBAqLBDtDZK_KuG8qzcjYYkMZ&street=pune&city=Pune&state=India";

WebRequest req = HttpWebRequest.Create(url);
req.Proxy = WebRequest.DefaultWebProxy;
....... and so on

oops.. getting a WebException again.. The underlying connection was closed: An unexpected error occurred on a receive.

Ok could we try WebCliet instead?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
 
namespace YahooTest
{
    class Program
    {
        static void Main(string[] args)
        {
            WebClient client = new WebClient();
 
            string data = client.DownloadString("http://local.yahooapis.com/MapsService/V1/geocode?appid=35jF1DfV34HKjqV6hOQvXaXUv3Gui63U2_EAX44gFRylBAqLBDtDZK_KuG8qzcjYYkMZ&street=pune&city=Pune&state=India");
 
            Console.WriteLine(data);
 
            Console.Read();
        }
    }
}

nopes Dave:(
getting a WebException again.. The underlying connection was closed: An unexpected error occurred on a receive.

Are you trying to run the exe on ur personal computer or does it have any domain / firewall setting?

I am at work but not using a proxy.
If what you are doing is for work, maybe you need to speak with your firewall administartor?

There is a catch here.. If I type in the url in web browser (IE 7 or firefox 2) then it responds with correct output. I tried to use sniffer tool for IE there it gives me an error
---------------------------
407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied.  )
--------------------------
still I could see the output in browser. Can you help me to understand the issue ?

This actually works without proxy. Proxy setting has something to do with it so the question is partially resolved.

Ok nice one
