calling a webservice method.

Hello.

I have to call a function on a webservice with the following syntax:

Delivery(Username As String, Name As String, AccessID as string, XMLFile As String) As String

The webservice address is something like:

http://www.website.com/delivdev/delivery.asmx?wsdl

The XMLfile is in Utf-8 and contains several items to be exported, according to an XSD file that validates the XML file I create.

How can I do this using Chilkat activeX ( for example in FoxPro )?

Thanks,

Carlos
