I've got 2 applications (lets call them AppA and AppB) communicating with each other. AppA is sending objects to AppB. There could be different objects and AppB does not support every object.

Hello all, I got a C++ object oriented program that was working right. I have decided to modify it by adding some polimorpysm definining a class hierarchy with virtual methods. When I call the virtual method it produces an fault segmentation error, likely because I have trash in the object. This is the call and the warming up GPU...

It was useful, because I could directly use this list of Movies and all their attributes without any other ...

Do I really need a separate TimerT...
