[AccessD] A diff program for Access?

[Bill Benson]

So if you learn to program the VBE uou can loop through an app’s  VBProject
with

Air code

For Each vbComponent in VBProject.VBComponents

>From there to get to code is

Vbcomponent.codemodule.lines (number of lines)

You need a reference to VBA Extensibility 5.something.

For excel you also have to trust VBA Object Model not sure with Access.

Programming the VBE is a very big undertaking if trying to write code,
fairly simple for reading.


There is also MZTools that lets you export all modules as bas and cls files
so you can compare them in winmerge. But that is gonna be better for
comparing one update to another. But it wil show you code modules on the
left that arenton the right in a somewhat user friendly format.

I am sure others can recommend more robust methods.
