ReplaceLast - Replace the last occurrence of a substring

' Replace the last occurrence of a string

Function ReplaceLast(Expression As String, Find As String, ReplaceStr As String, _
    Optional Compare As VbCompareMethod) As String
    Dim i As Long
    i = InStrRev(Expression, Find, , Compare)
    If i Then
        ' the search string is there
        ' note that the Replace function trims the first part
        ' of the string, so we must restore it using Left$
        ReplaceLast = Left$(Expression, i - 1) & Replace(Expression, Find, _
            ReplaceStr, i, 1, Compare)
        ' the search string isn't there
        ReplaceLast = Expression
    End If
End Function
