>Recently, there was a thread where I showed a link which allows to dynamically call a method into a Web Service. This was allowing us to build a small EXE and put some textboxes in it to enter the method name. Thus, the code was flexible enough to adjust and use that generic code to call the required method at the Web Service level. That works well. However, that approach does not support the fact that we could add a query string to the URL of the Web Service. If we do so, the code will not work as the register of the object need to be the .asmx + the ?wsdl, which does not make any room for a query string.

The above links didn't work for me. But Webservices use SOAP/POST so query strings won't normally work.
If it's your web service that is being called you might be able to use something like this :http://stackoverflow.com/questions/2006828/possible-to-invoke-asmx-service-with-parameter-via-url-query-string

If not you'd have to build your own Soap request.....
