I just finished finally getting www.pocketSOAP.com to work with my VBA
client program to access a web service. What is unique about my
requirements, besides using VBA, is that the web service requires two
parameters be sent as part of the header. That capability is not
provided by the Office Web Services toolkit does not support.

If you don't need to provide data in headers, I have found the Office
Web Services toolkit to work quite well.

Finally, the author of POcketSOAP, Simon provides outstanding and timely
support to questions posed on the news group for the software.
You can see my code posted on the news group for PocketSOAP.
