Re: [Boost-users] How shared_from_this() work when it inheritedfrom more than one time

Don't let B inherit from enable_shared_from_this. You've already done that in A. So your question then becomes "how do I retrieve a shared_ptr<B> from this?". Here's how:

 boost::shared_dynamic_cast(shared_from_this());

Why not: boost::static_pointer_cast<B>(shared_from_this());
