"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

try something like this:

``````Const Limit As Integer = 3

Public Function GetDouble(v As String) As String
Dim tmpArr(Limit - 1) As String

If Len(v) = Limit Then
tmpArr(0) = Mid(v, 1, 1)
tmpArr(1) = Mid(v, 2, 1)
tmpArr(2) = Mid(v, 3, 1)

For i = 0 To Limit - 1 - 1
For j = i + 1 To Limit - 1
If tmpArr(i) = tmpArr(j) Then
GetDouble = tmpArr(i) & tmpArr(j)
Exit Function
End If
Next j
Next i
End If
GetDouble = ""
End Function

Public Function GetNotDouble(v As String) As String
Dim tmp As String
Dim tmpArr(Limit - 1) As String

For i = 0 To Limit - 1 - 1
