Hello Folks

We are porting an AI application under VC++ 4.0 using MFC.
In this application we explore different level of hypothesis(as a
tree).
In each level (i.e. Layer i) we have a view of all the objects which
were known at Layer  i-1 plus modifications brought at level i.

We want to be able to build different  layers for the management of
hypotheses.

How to do it in C++ using MFC

exemple
Layer 0 we have :
One object A with attributes A1 =10 and A2 = 20

We build a second layer  Layer 1
We have the visibility of Layer 0 , we can see the object A with the
values of the attributes A1 and A2 respectively 10 and 20.
We set the value of A.A2 to 200
In this layer the values of the attributes A1 and A2 are now
respectively 10 and 200

and so on for ALL the objects in the application.

We wouldn't like to have all the objects duplicated but only the
differential between layers.
We want to be able to backtrack from one layer to a precedent one.

If someone knows how to  do it will  help us a lot.
Thanks


Pierre
