>I've seen the live tutorial. I'm not impressed by the result.

It's intentionally simple, just meant to show how control/events are supported, and how code is adapted.

This live application might impress you a little more (login 'SG', pass 'SG')

>And what it doesn't show is how maintainable is the code

The code remains in the usual *.prg, *.vcx, *.scx, etc.

Maintenance is just the same as for the desktop application.

You can test your application in desktop mode, then web mode; eg copied from my command window:

do "c:\program files\vfp9\tools\ab\aw\samples\fic\fictuto\tutolan.prg" && desktop start
do "c:\program files\vfp9\tools\ab\aw\samples\fic\fictuto\tutotest.prg" && web start
