I would like to know what web services are used for in vb.net.
I know that we can develop a web application, but don't know what webservices are used for?
any simple explanation?
thanks

>> If I understand, even if we develop a web application with vb.net it will be usefull only for clients that have the vb.net application deployed.
NO, Web Services are a standard way of data interchange between aplications, your web service written in vb.net can be called from an app/web site written in Java/JSP or for that matter any or most of the languages. Also the vice versa, a Java web service can be called by vb/c# etc.
>> if we develop a web service application with vb.net , how are we going to deploy it so that other systems can access it?
You deploy it on a Web Server just like you do a normal web site, then the clients who want to call your web service use UDDI to look for your web service and use a proxy to call your web service, look for these terms on the net for more info, just for deploying issues refer

>> if we have a web application developped by vb.net , can we convert it to a web service application and deploy it to different systems, or do we have to develop a new web service application from scratch?
Web Services are a type of App in VS.NET so you need to first create Web Services application, this of course you need to do manually (from scratch, i.e. you do not have a wizard as far as I know) But then once you have an empty Web Services app you can use existing Classes etc. i.e. you can add reference to the DLL and use the classes/functions from another assembly.
