maybe this works:

const std::vector<Event> v;
std::vector<Event>       vOut;

std::remove_copy_if(v.begin(), v.end(),
                    back_inserter(vOut),
                    boost::bind(std::logical_and<bool>(),
                               (boost::bind(&Event::GetEventType, _1) == 0),
                               (boost::bind(&Event::GetEventID, _1) == 1)));
