Then inheritance and polymorphism are useful. Inheritance can be a maintanance nightmare. To be really able to reuse inheritance effeciently. you need source code. Thus, inheritance is very usefull for in-house development. When you use objects written by other companies, you should use aggregation instead. Approach of Microsoft's OLE is surprisingly effecient and reusability is high. Vlastimil Adamovsky ** C++ and Smalltalk consultant ** * http://www.stepweb.com *
