A dirty "hack" is to make a function which tests the array

if not dim - then return -1

like this

Option Explicit

Private Sub Form_Load()

Dim arr() As Long
'ReDim Preserve arr(10)
MsgBox TestArray(arr)

End Sub

Function TestArray(vArr() As Long) As Integer

Dim i As Integer

On Error Resume Next ' turn off errorchecking
i = UBound(vArr)
If Err <> 0 Then 'Array is not dim
i = -1
Err.Clear ' clean up
End If
On Error GoTo 0 'turn on normal errorchecking
TestArray = i

End Function
