Refresh Excel VBA Function Results

Question

How can I get a user-defined function to re-evaluate itself based on changed data in the spreadsheet?

I tried F9 and Shift

Answer 1

This refreshes the calculation better than Range(A:B).Calculate:

Public Sub UpdateMyFunctions()
    Dim myRange As Range
    Dim rng As Range

    ' Assume the functions are in this range A1:B10.
    Set myRange = ActiveSheet.Range("A1:B10")

    For Each rng In myRange
        rng.Formula = rng.Formula
    Next
End Sub
