I am writing an add-in for Excel 2003, using VBA.
I have an Auto_Open subroutine, which automatically runs some code (setting up menus, etc) whenever the add-in is Opened as a file.
What subroutine name (or other logic) do I need to use in order to have code that automatically runs when the add-in is “Enabled” through Excel’s Add-in manager? (And, relatedly, when it is Disabled)
Auto_Open and Auto_Close will do what you want. Checking the addin in the Addins dialog opens it, and unchecking it closes it.
