Prevent UDF from being called on vba Excel Sheet Deletion/Addition

Question

Before Deletion and Creation of Worksheets using

Sheets(xxx).Delete 

or

Worksheets.Add(Before:=Worksheets(xxx)).Name = xxxxxx

User Defined Functions(UDF) are being called.

Is there a way to prevent UDF being called. I just want to create or delete a sheet

Answer 1

When Excel is in Automatic calculation mode deleting a worksheet triggers a recalculation.
If your UDFs are Volatile or downstream dependent on a volatile function or a cell on the deleted worksheet they will be recalculated.
See http://www.decisionmodels.com/calcsecretsi.htm for more information on volatile functions and actions that trigger a recalculation.
