I have converted several foxpro applications to the latest versions. I in fact had written two commercail software packages in Foxpro Dos and then successfully upgraded them into VFP and later VB.NET.
I will need to get the application and review to confirm the cost. I can port to VFP using dbf files or update the database to use SQL if desired.
I hope that we can work together to achieve a solution which works for your needs.
Cheers,
Brent McCaw
