Published DataFlex powered Web Services are available to assist developers now with learning and testing the use of Web Services in their applications.

The "Conversions" DataFlex Web Service, developed by DAW’s Marcia Booth, provides a variety of functions that will convert numbers into words (English), numbers into dollar amounts, and texts into title-cased texts.

The service can be tried by anyone by visiting the Conversions DataFlex Web Service page hosted by Data Access Worldwide.

The Conversions service has already been found useful by one enthusiastic developer:

I wanted to thank you for providing an extraordinary web service by way of your Conversions WSDL! I’ve consumed this service in a practice smart client app and was utterly amazed at how it all works! If I had to write the code to convert numbers to words it would take a considerable amount of time. I was able to set up a few lines of code and consume your conversions service in LESS than 5 minutes! It’s just a practice app but your WSDL is great! Your web service was the first one I’ve consumed programmatically! Thanks!
