ArrLongestItem - The value and index of the longest element of an array of any type

' The longest item in an array of any type
' (it applies the LEN function to all the items in the array
'  and then takes the highest value)
'
' FIRST and LAST indicate which portion of the array
' should be considered; they default to the first
' and last element, respectively
' if LONGESTINDEX is specified, it receives the index of
' the longest element of the array

Function ArrLongestItem(arr As Variant, Optional ByVal First As Variant, _
    Optional ByVal Last As Variant, Optional LongestIndex As Long) As Variant
    Dim index As Long
    Dim maxLength As Long
    
    If IsMissing(First) Then First = LBound(arr)
    If IsMissing(Last) Then Last = UBound(arr)
    
    ArrLongestItem = arr(First)
    maxLength = Len(ArrLongestItem)
    LongestIndex = First
    
    For index = First + 1 To Last
        If maxLength < Len(arr(index)) Then
            ArrLongestItem = arr(index)
            maxLength = Len(ArrLongestItem)
            LongestIndex = index
        End If
    Next
    
End Function
