Hi all,
(excuse me for my terrible english!)
I have a COM obj_1 (source code!) and I need to create another COM obj_2 that has the same interfaces but for same methods I'd like to add same functionality (I can't modify obj_1 impl.!).

For example, obj_1 has one method that returns same info from the server... I need to add same fields (like "record just imported" and "desc.&quot to this info. I can store the additionally fields in a local DB but how can I create obj_2 from obj_1?
I must use VIsual C++ 6 an I can use ATL too...




Best regards, bye from Italy!!!!
Marco

use aggergation. By using aggregation you could expose serevr's interfaces as your own. In this way, you can extend/subclass the server.
