Thanks. I understand what _1 does. I thought that leaving off the real arguments and giving only the object would produce a function object taking those same arguments. I guess the compiler can't hand that automatically? Now I get V:\boost_1_47\boost/bind/bind.hpp(69) : error C2825: 'F': must be a class or namespace when followed by '::' V:\boost_1_47\boost/bind/bind_template.hpp(15) : see reference to class template instantiation 'boost::_bi::result_traits<R,F>' being compiled with [ R=boost::_bi::unspecified, F=void (__thiscall S::* )(uint32_t,call_state_machine::State_t,call_state_machine::State_t) ] .\StateMachine\Call\Windows\StateProcess.cpp(54) : see reference to class template instantiation 'boost::_bi::bind_t<R,F,L>' being compiled with [ R=boost::_bi::unspecified, F=void (__thiscall S::* )(uint32_t,call_state_machine::State_t,call_state_machine::State_t), L=boost::_bi::list2<boost::_bi::value<S *>,boost::arg<1>> ] V:\boost_1_47\boost/bind/bind.hpp(69) : error C2039: 'result_type' : is not a member of '`global namespace'' V:\boost_1_47\boost/bind/bind.hpp(69) : error C2146: syntax error : missing ';' before identifier 'type' V:\boost_1_47\boost/bind/bind.hpp(69) : error C2208: 'boost::_bi::type' : no members defined using this type F in the first complaint is the pointer-to-function type, so I agree that F::result_type doesn't make sense.
