instrrev

How do I go about using the instrrev function in my Access'97 VBA. It won't let me use it right now.

I think INSTRREV is only supported by Office2000 and VB6 and up.

You can create your own INSTRREV function by using a FOR LOOP with STEP -1.

If you don't know how, post again and I will create one for you.

I tried using an InstrRev Function made by Ian17 I found in the forum, but i don't think it works that effectively. I'm still trying to figure it. It would help me a lot if you could post your instrRev function too.

thanks,
Matt

Here is an InstrRev function from MSDN

Code:

---

Public Function InStrRev(ByVal sIn As String, sFind As String, _
 Optional nStart As Long = 1, Optional bCompare As _
      VbCompareMethod = vbBinaryCompare) As Long
    Dim nPos As Long
    sIn = StrReverse(sIn)
    sFind = StrReverse(sFind)
    nPos = InStr(nStart, sIn, sFind, bCompare)
    If nPos = 0 Then
        InStrRev = 0
    Else
        InStrRev = Len(sIn) - nPos - Len(sFind) + 2
    End If
End Function

---

I just realized you need a function called StrReverse which is used in the above example.

Code:

---

Public Function StrReverse(ByVal sIn As String) As String
    Dim nC As Integer, sOut As String
    For nC = Len(sIn) To 1 Step -1
    sOut = sOut & Mid(sIn, nC, 1)
    Next
    StrReverse = sOut
End Function

The one that I was going to post is similar to the second one the Megatron posted. That should be almost equivalent to INSTRREV function.
