I am fairly new to creating asp.net web services - I've had good luck setting up a basic asp.net wrapper to pass xml strings back and forth for a sync program. My current challenge is to send a few pdf files from VFP to asp.net and vice-versa. I tried sending an fread() string through to asp.net, but obviously this doesn't work well in an XML stream. Internet and UT searches didn't come up with much on how to do this (hopefully) simple procedure. Does someone have some simple example code to share on this?

goal:
VFP - send pdf file to asp.net. asp.net saves pdf file to local filesystem.
.NET - send a different local pdf file back to VFP through web service.

Thank you!
