Hi Evan

Main aim of the convertion is to give Windows interface feeling to the software so that we can call it as ' Windows version '

How stable is Foxpro for Windows 2.6. It's packaged software & we sell at other cities through our Dealers.

Another constraint is time. We would like to have a Windows version at the earliest. Another factor is cost. We would like to sell the software at the same cost as DOS version & phase out DOS version. A re-write in VFP might involve more time than conversion.

A fresh, starting from scratch VFP version with OOP's programming will also be started later.

>My opinion is to not attempt a conversion of the program, but instead rewrite it. Here are my reasons:
>- the conversion is rarely smooth, you will need to tweak it alot to get it working and looking good
>- if you convert you will have a slow (user interface wise) verion of your old program that has no added functionality. So in essence you have made your program worse
>- why move to VFP if you aren't going to take advantage of its features
>- forms converted from FPD are almost impossible to maintain because they contain a lot of code and pageframes to make everything work in VFP
>- you will not learn how program in VFP properly since you will still be using the old FPD techniques in your application
>- it is difficult to integrate new forms into an app that has converted forms
>- your learning curve for VFP will be lengthened

>I have formed these opinions from converting a major FPD app to VFP3. My learning curve of VFP was stretched from 2 or 3 months to almost a year. It took almost 1.5 years to remove the last bits of old code from the system.

>>We have a large Accounting sotware written in FPD 2.6. Now we would like to convert to VFP 6.0. We are NOT planning a rewrite because we would be starting Fresh with OOPs progamming with more features later on. At present would to like to just convert to VFP with the same code.

>>1. Migration Strategy.
