OK, here is my idea, use the current time along with some other random letters

Private sub command1_Click()
    dim code as string
    code = GetCode()
    ' now save the code to database...
End sub

Private Function GetCode() As String
    Dim i As Long
    Dim c As Long

    Randomize
    c = Int(Rnd(1) * 5) + 1
    For i = 0 To c
        GetCode = GetCode & Chr(Int(Rnd(1) * 26) + Asc("a"))
    Next i
    GetCode = GetCode & Format(Now, "YYYYMMDDHHNNSS")
    Randomize
    c = Int(Rnd(1) * 5) + 1
    For i = 0 To c
        GetCode = GetCode & Chr(Int(Rnd(1) * 26) + Asc("a"))
    Next i
End Function
