Sounds like an interesting project. Here are some places to start:
- check the UT knowledgebase for a few internet articles
- check West Wind for some more http://www.west-wind.com/Articles.asp

Some technologies to put an app on the web (off the top of my head):

For these next 4 you need to rewrite the app or at least the portion that is accessed from the web
- Web connection from www.west-wind.com
- www.x-works.com
- www.foxweb.com
- www.activefoxpropages.com

This next one will allow you to run the app as is but requires an investment is software. Not very scalable since the app is run on an NT server.
- use cytrix to access app "as is" over the internet www.cytrix.com

Similar to above but user signs onto a specific computer and runs app (not on the server as above. Only screens are sent down the wire
- use PcAnywhere

Others will have more ideas..

>Talk about diving in at the deep end. I haven't even completed a straightforward vfp project (upgrade from 2.6) but I'm being asked to report on the hows, costs and timetable for putting an automated sales application on the web.
>Can someone please point me in the right direction for complete novices (web application wise)
