• IClassFactory

• Inheritance

Note

When I talk about differences in speed, I am referring to numbers that were compiled with one computer. Other computers will produce slightly different results. I have a Windows 2000 installation that suggests that COM+ is 11 times slower than equivalent C++.

I occasionally talk about equivalent C++. C++ is not a language that ...
