Mathew,
>Does anyone have experience in updating existing version of the software application written in VFP 7 to new version or any version of VFP? In my case, there will be new forms; class, reports and some table structures will be altered. What should I considered before diving into it? TIA
There are very few changes needed going from VFP7 to VFP8. You should look at VFP8's
SET ENGINEBEHAVIOR 70
command to avoid errors with some SQL Statements involving GROUP BY. (You ultimately should change the SQL Select statements to conform to the higher standards that the default VFP8 behavior requires for GROUP BY.
The other major problem area might be the OS requirements for running VFP8 development version (Win2K or above) and runtime (Win95 not officially supported).
Other than that, just post questions here if you have problems and the UT community will help you get them resolved quickly.
