Here is a basic function I have: bool MimeDocument::GetExistingAttachment( std::string const& filename, std::vector<MessageAttachment> const& attachments, MessageAttachment& attachment ) { using namespace boost::lambda; using boost::lambda::_1; std::vector<MessageAttachment>::const_iterator it = std::find_if( attachments.begin(), attachments.end(), bind( &MessageAttachment::name, _1 ) == filename ); if( it != attachments.end() ) { attachment = *it; return true; } return false; } MessageAttachment::name() has 2 overloads, one that takes 1 parameter and the other that takes no parameter. I'm attempting to call the version that accepts no parameters and returns a "char const*". I want to then compare this value to the local variable "filename". This should happen for each object in the vector (_1). I get various types of compiler errors on MSVC9. They all have to do with C2780: 1>c:\code\work\cmake-mds\server\gmmserver\domino\server\interface\dimime.cpp(287) : error C2780: 'const boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<10,boost::lambda::function_action<10,T>>,detail::bind_tuple_mapper<const Arg1,const Arg2,const Arg3,const Arg4,const Arg5,const Arg6,const Arg7,const Arg8,const Arg9,const Arg10>::type>> boost::lambda::bind(const Arg1 &,const Arg2 &,const Arg3 &,const Arg4 &,const Arg5 &,const Arg6 &,const Arg7 &,const Arg8 &,const Arg9 &,const Arg10 &)' : expects 10 arguments - 2 provided 1> c:\code\work\cmake-mds\build-vc9\third_party\boost\1.48.0\include\boost\lambda\detail\bind_functions.hpp(1743) : see declaration of 'boost::lambda::bind' Anyone have any idea what I'm doing wrong? --------- Robert Dailey
