[exel] How to count different number?

Dear all,

here is the case:
I have some rows with six columns each.

does any body know how to count how many different number in each row?

ex: 1 - 3 - 1 - 2 - 4 - 5 >> 5 unique numbers
1 - 2 - 3 - 2 - 2 - 4 >> 4 unique numbers and so on.

Try this:

Code:

---

Public Sub test()
Dim Values() As Single
Dim i As Integer
ReDim Values(5)
For i = 0 To 5
    Values(i) = Cells(1, i + 1).Value
Next i
MsgBox ("You have " & different_values(Values) & " values!")
End Sub
Public Function different_values(Values() As Single) As Integer
Dim i As Integer
Dim j As Integer
Dim k As Integer
Dim Check As Boolean
j = 0
Check = False
Do
    For i = j To UBound(Values) - 1
        If Values(j) = Values(i + 1) Then
            For k = i + 1 To UBound(Values) - 1
                Values(k) = Values(k + 1)
            Next k
            ReDim Preserve Values(UBound(Values) - 1)
            Check = True
            Exit For
        End If
    Next i
    If Check = True Then
        j = 0
    Else
        j = j + 1
    End If
    Check = False
Loop Until j = UBound(Values)
different_values = UBound(Values) + 1
End Function
