>Well, in order to copy something into something, both entities have to be the same definition. In my case, oProcess.oApp.Tables is a NameObjectCollectionBase class and this is what I need to copy. For some kind of reason .NET does not want to allow me to do that. I have made a perfect copy but only changed the name. That did not work. I also copied the entire structure and assigned new names. This also did not work.

You need to replace the App.oApp.Tables p[roperty with a new instance, ie the same class but another instance
