I have a client who is running a website which we think would benefit from calling a complex function that I have written in VFP. The function must be able to accept 6 parameters and returns 5 output values. I am therefore thinking of providing the function as a web-service that will will accept the input parameters and output values as XML strings. The service is to be hosted on the client's web-server machine, which is not connected to the development machine.

What files will I have to send to my client? From what I have read so far I guess they will need at least the following...
Web-service .dll file
VFP8 runtime files
WSDL/WSML files created by publishing wizard
Any others?

The function will require access to some small .dbf tables. Rather than supply these as separate files, is it ok to included them in the .dll (as I would for an .exe running on a network)?

Apart from the SOAP toolkit, what else will my client need to install the service? Must the web-server be running IIS, or could it be a non-Microsoft server such as Apache?

Any other help would be appreciated. Is a web-service the best way to go? Are the FFC web service foundation classes worth looking at? Are there any good articles/papers out there that could take me through the process?

Many thanks,
Alan Harris-Reid
