The following procedure runs when the user clicks a button in a VBA user form. It removes a property object from a properties collection using the Remove method:
Private Sub RemoveColorProperty_Click() Dim ItemCollection As DUOSObjects Dim ItemObject As DUOSObject Dim ItemProperties As DUOSProperties Set ItemCollection = DUOSObjectsGet("ItemInfo") Set ItemObject = ItemCollection(ItemNumber) Set ItemProperties = ItemObject.Properties If ItemProperties.Exists("Item Color") Then ItemProperties.Remove("Item Color") End If End Sub
