I have a ListBox on a form that shows me all the layers that exist in my drawing. Is there a way that I can have it tell me if the layer is On/Off, Froze/Thawed? These are the only two options I want to know about. I also have buttons that can toggle the highlighted layer On/Off or Frozeen/Thaw, but I have no way of telling if it is Frozen or Thawed. Thanks, Keith
