Cornerstone of a service oriented architecture
Visual DataFlex Studio has a tool to use a Web Service class from dataflex code ( VDF Webservice Class )
The generated webservice client may use Call By Reference to return results.
Coding webservices
Usually , when coding webservices there are two approaches - "contract first" and "model first".
When using "Contract first" you usually get a WSDL file that your webservice must adhere to. When using "Code first" you typically write the code first and use a tool to generate the WDSL from the code.
The standard approach using Visual DataFlex is to use "code first".
