Your question is hard to understand, could you try and rephrase it please?
</div>

<div>
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 = &quot;<a href="http://local.yahooapis.com/MapsService/V1/geocode?appid=35jF1DfV34HKjqV6hOQvXaXUv3Gui63U2_EAX44gFRylBAqLBDtDZK_KuG8qzcjYYkMZ&street=pune&city=Pune&state=India" rel="ugc">http://local.yahooapis.com/MapsService/V1/geocode?appid=35jF1DfV34HKjqV6hOQvXaXUv3Gui63U2_EAX44gFRylBAqLBDtDZK_KuG8qzcjYYkMZ&street=pune&city=Pune&state=India</a>&quot;; 
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.
</div>

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

</div>

<div>
I am afraid, I cant test it outside firewall. 
</div>

<div>
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 &nbsp;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(&quot;---- my proxy------ &quot;, 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.
</div>

<div>
Ok this is a bit of a guess but try this: 
 
req.Proxy = WebRequest.DefaultWebProxy; 
So we have...

....... and so on

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

<div>
Ok could we try WebCliet instead?

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?
</div>

<div>
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? 

</div>

<div>
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. &nbsp;) 
-------------------------- 
still I could see the output in browser. Can you help me to understand the issue ?
</div>

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

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
