- 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
-
