web services time out issue

I found the article but I am not sure how and where to implement the code.

Protected Overrides Function GetWebRequest(ByVal uri As System.Uri) As System.Net.WebRequest
 Dim webRequest As Net.HttpWebRequest = CType(MyBase.GetWebRequest(uri), Net.HttpWebRequest)
webRequest.KeepAlive = False
Return webRequest
End Function

I copied the exact code and put it right under the imports statement on the top of the form code but geting error.

This article describs how to implement the code.

Solving "The underlying connection was closed: An unexpected error occurred on a send." (Webservices)
UPDATE: For solution when using WSE, see here!

Sometimes when you invoke a webservice the call fails with the following exception:

System.Net.WebE xception: The underlying connection was closed: An unexpected error occurred on a send.
at System.Web.Serv ices.Protocols. WebClientProtoc ol.GetWebRespon se(WebRequest request)
at System.Web.Serv ices.Protocols. HttpWebClientPr otocol.GetWebRe sponse(WebReque st request)
at System.Web.Serv ices.Protocols. SoapHttpClientP rotocol.Invoke( String methodName, Object[] parameters)
at ...

In some cases the first call to the webservice works just fine, but if in the following few minutes no new call to the webservice is made, the next call would throw the exception shown above. This problem could be solved by altering the generated proxy class; in the GetWebRequest function the KeepAlive property must be set to false. This can be accomplished by following these steps:

Add a Web Reference using the normal way (if you haven't already added one ofcourse).
Make sure Show All Files menu item is enable in the Project menu.
In the Solution Explorer window, navigate to:
Web References
<Name of your webservice>
Reference.map
Reference.cs (or .vb)
Open the Reference.cs file and add following code in the webservice proxy class:

protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
 System.Net.HttpWebRequest webRequest = 
  (System.Net.HttpWebRequest) base.GetWebRequest(uri);
 webRequest.KeepAlive = false;
 return webRequest;
}

Dorandoran, could you please explain the problem you're facing.
It seems you are having a problem solving another problem.
Could you please explain the original problem before you continue to use code that you don't fully understand?

Thanks,
