Web Service - VB 2008

Dear All,

I have an idea to develop a handheld online application in order to post receipts and shipments online. as a test i published the purchase order page as a webservice, created a new project in vb 2008, my question is: how to read/modify/add data to the objects that i've got by adding the web service as a reference? i noticed the service and the objects, i tested the service in a console applicaiton and it's working fine, but i couldn't get the idea of binding data to/form the exisiting data objects in windows forms.

Thanks,

Phoenix
