>I have a client that wants to convert a number of their distributed FPD26 apps to run over the web. I am proposing using VFP. They are a bit leary of how the app would respond and have asked me to find some site(s) that use VFP over the web for data entry processes.

Actually, the things you're going to have problems with for your web-based app. are the same types of things you'd have to deal with with any web-based engine. You mentioned that they do a lot of column/row (grid) type of work. You're going to have a lot of problems making this work well with ANY engine because of the limitations of HTML. Yes, there are ways of handling it that might work (ActiveX controls, JavaScript, etc). Since you haven't mentioned any of the other requirements it's hard to give specifics (ie. can you standardize on a browser, are ActiveX controls acceptable, etc).

One alternative is to use a VFP-based frontend w/a web backend. You get all the nice controls and UI of VFP while the real processing is happening on the web server. If they need to also be able to look up info, etc via a normal browser you just code up a HTML page and you're set. Rick's page (http://www.west-wind.com) has info. on doing this in the whitepapers section.

I think you're going to have problems finding actual sites (VFP or any other) that use heavy data entry processes. Most type of apps like this are on peoples Intranets and not really available for anyone to screw with.

To sell them on the idea you might have to code up a simple page that incorporates their normal data-entry screens with a real VFP web backend. You can download a working copy of WebConnnect before buying it.
