Recently we had the task of getting a large number of customization that had been created using VBA and Modifier to function on the GP2015 Web Client. Since VBA will not function on the web client, we had the option of re-writing the functionality in Dexterity or Dot Net.

For years I have been creating customizations for Microsoft Dynamics GP using a combination of Modifier and VBA. This has always worked well for me in the past with a few quirks and hiccups in VBA from time to time. I have created simple additional fields on screens, complex logic to enhance our customers business and many other types of projects. All of this has worked well, been easy to upgrade to the next GP version and been basically stable code for many years.
