This looked like a good candidate for a FAQ!

raskew (Programmer) Apr 1, 2002
Function xLastInStr(tstr As String, twhat As String) As Integer
'*******************************************
'Name:      xLastInStr (Function)
'Purpose:   Return location of last instance of a character or phrase.
'Inputs:    Call xLastInStr("the quick brown fox jumped the lazy dog", "the")
'Output:    28 - Location of last occurence of "the"
'*******************************************

Dim i As Integer, n As Integer, tlen As Integer

n = 0
tlen = Len(twhat)
For i = Len(RTrim(tstr)) To 1 Step -1

  If Mid(tstr, i, tlen) = twhat Then
      n = i
