Hello : Is there safe/easy way to downcast shared pointers? ie boost::shared_ptr< Derived_Type > dPtr = [appropriate_method_here] ( base_ptr ); Thanks in advance; Steve a.

Look at the *_pointer_cast functions... http://www.boost.org/libs/smart_ptr/shared_ptr.htm#functions shared_ptr -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq

You could downcast reference instead of shared_ptr. Derived_Type& derived_ref = polymorphic_downcast<Derived_Type&>( *base_ptr ); I am not sure it what you want though. Gennadiy
