I have a form button placed on a sheet. It is assigned to a fully
qualified macro name, as in wb.xlsm!sheet.addRows.

Concerning the Application.ActiveSheet method.

Can I be sure that an early call to Application.ActiveSheet in the
macro returns the sheet upon which the button resides?

Seem to be true, but I've read, somewhere, that the active sheet may
change at any time and this really isn't to be depended on.

How can I insure that the sheet I retrieve is the sheet where
the button resides?

#2 AND, if it can not be relied on, should you ever use it?
