Hi,

What is wrong in my syntax in the std::for_each call (the BOOST_FOREACH works fine):

...
class Session
{
        virtual void stopSession();
}

class ServerSession : public Sessoon
{
}

typedef std::map<unsigned long, ServerSession*> ServerSessions;
ServerSessions serverSessions;
...

...
typedef std::pair<unsigned long, ServerSession*> ServerSessionsIterator;
BOOST_FOREACH(ServerSessionsIterator session,serverSessions)
{
        session.second->stopSession();
}

std::for_each(	serverSessions.begin(),
                      serverSessions.end(),
                      boost::lambda::bind( &ServerSession::stopSession, // function
                                           boost::bind(&ServerSessions::value_type::second, boost::lambda::_1))); // object

The actual error is:
