Thanks Pinto for the code. I had a problem with my SOAP toolkit instellation. Now it is working fine. Now I have a different problem.
Afrer publishing the web service and working with it I decided to change the code in my original program. Afrer changing the code when I tried to rebuild the project to make the required "DLL", I get the file access denied message. It seems the file is in use. I tried to locate it using component services, internet information services etc in control pannel. But coudn't locate it. How do I stop it?
