I just realized if I replaced

shared_ptr<B> pB(dynamic_pointer_cast< shared_ptr<B> >(pA));		

with 

shared_ptr<B> pB(dynamic_pointer_cast< B >(pA));		

It will compile. What I'd like to know is if this is the way to do it. 
Initially I thought that the enanble_shared_from_this_0.cpp was the way 
to go, however it generates a run-time error.
