Handle Error 9 when there is an Empty Array

I am writing a script that will loop through an Excel spreadsheet and find if there are duplicates of selected cells. If there are duplicates then the function will return an array of which rows are duplicates and create a comment to tell me the rows.

I have been able to handle error 0 but now I am getting error 9 when I check if there are elements in the array using the UBound function.

How do I validate if the array of integers is empty?

Function IsArrayEmpty(anArray As Variant) As Boolean
    Dim i As Integer

    On Error Resume Next
        i = UBound(anArray, 1)
    Select Case (Err.Number)
        Case 0
            IsArrayEmpty = True
        Case 9
            IsArrayEmpty = True
        Case Else
            IsArrayEmpty = False
    End Select
End Function
