When you make an XLS file act as an add-in -- that was how I built
my first menu-building Excel add-in -- you're supposed to twiddle
the IsAddIn property of the ThisWorkbook object when you edit the
code. That much I remember. But what's the proper sequence for
that. Is it this?

Open the VBE
Change IsAddIn to False
Edit
Change IsAddIn to True
Save (apparently needs explicit, doesn't prompt at close?)

Also, when I forget to do this, it doesn't seem to matter much.
What's the purpose of changing that property? Is it only to
make the add-in not visible? (And if so, why is that necessary
[assuming there's no content on its worksheets] since you can
still get at the code?)

TIA

Thank you both for this.

if you have an xls
then file saveas addin

afaik this does:
saves a copy in the addin folder as an XLA not an XLS
toggles the isaddin property

if you did it manually... you haven't forgotten
that you need to set the file extension to XLA?

the isaddin property toggles visibility of the workbook
(and i believe the names and macro's)

to edit the code you dont need toggle it
but indeed addin changes are NOT saved automatically on close.
if isaddin = true
