Vous pouvez demander une liste des propriétés lisibles ou inscriptibles.
Bonus, demandez si une propriété spécifique existe.
Public Function DoesPropertyExist(pObject As Object, ByVal _
PropertyName As String, pType As EPType) As Boolean
Dim Item As Variant
PropertyName = UCase$(PropertyName)
For Each Item In EnumerateProperties(pObject, pType)
If Item = PropertyName Then
DoesPropertyExist = True
Exit For
End If
Next
End Function
