Really all you have to do is comment out the SetConnections() method in the AppMain.vb file. If you are going to have BOs this becomes more tricky. You can create a "dummy" connection, but any Save() or Undo() calls will fail since it will try to use the connection.
The Save methods are overridable so you could handle those in your code. For the Undos you could mark them overridable in the source, re-compile and handle them any way you like. I’m already doing that with the Add method.
Larry, I will add the override ability to the Undo so you don't have to change the source in the future.
