[AccessD] Access FE --> VB: Conversion/Rewrite Time?

Hello Dan,
The project I refer to was a VB6 project.  For all intents and purposes
though, it could have been an Access project.

At the time there was a 'wizard' afair supplied by MS that converted VB6 to
VS2003.  It is this wizard that I refer to when I mention one hour.

However, for all but the marketing dept in MS, the wizard was absolutely
useless, and as we all know here, there is no comparison between VB6 and
VS2003/5/8/10.

In our case, the decision was taken to re-architect the application
entirely, and to use a virtual team based on three continents, and to
appoint senior manages on all three continents to be responsible and have an
influence on the final outcome.  Most people will not admit how much it
really cost to redevelop, but it was enormous.  Three or four years later,
there is no additional business functionality.

The project that I speak of reminds me so much of a book that Shamil
mentioned here last April named "Dreaming in Code".  That book is one that
every programmer should be made read.  And every customer also.

Why ?
What was the logic (if any) behind the decision ?
Was this SQL Server with VB.NET <http://vb.net/> or ASP.NET<http://asp.net/> or
???

The original application was a VB6 app, the new app is a multi-threaded,
multi-layer, system with multiple databases, windows services, web and
winform, and as much OOP stuff as you can shake a stick at.  And
requirements from many people that then up-ed and left the company.

I have to stop writing now as I feel my frustration rising :)

In summary though, I would suggest upgrade if you wish, but do not let it
take on a life of its own.  What is your ROI ?


Best of luck with it,

Mark
