Hello,

Could someone tell me why this code does not compile? Can it be modified in order to compile?

        struct CcyCplEventKey         {                 CurrencyCouple        CcyCpl;                 EventType                Event;         }

        typedef std::map mapType;

        mapType ccyOut;

        std::for_each(ccyOut.begin(), ccyOut.end(), (&*boost::lambda::_1)->*&CcyCplEventKey::Event);

Cheers

Ummm - for a start, a std::map iterator references a std::pair containing the key and value for that map entry, so you need to get hold of the 'first' member of the std::pair to use the key. Without type definitions for EventType, CurrencyEventPtr and CurrencyCouple, it's difficult to go further than that... Stuart Dootson
