    How to get poniter of array in Variant

    Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)

    Private Sub Form_Load()

    ReDim a(1 To 10) As Long

    For w = 1 To 10
    a(w) = w

    Debug.Print VarPtr(a(1)), Q(a)

    ' Error solution: Q(a) <> VarPtr(a(1))
    ' Positive solution: how to let Q(a) solution Equal VarPtr(a(1))

    End Sub

    Function Q(ar) As Long

    Q = VarPtr(ar(1))

    ' purpose of the Problem is the following

    Redim ar_2(1 to 10) as long
    call CopyMemory ( varptr(ar_2(1)) , Q , 40)

    End Function
