Hi Thaddeus, this code works for me... Greetings Tino int main() { std::string in; std::vector<A *> alist; std::vector<A *> longAList; typedef std::vector<A *> myType; // std::back_insert_iterator< myType > inserter(longAList); while(in!="end") { in=""; std::getline(std::cin,in); alist.push_back(new A(in)); } std::for_each(alist.begin(),alist.end(), //*inserter++ = &(*_1) boost::lambda::if_then( bind(&A::isLong,_1), bind(&myType::push_back ,&longAList, _1) )); return 1; } ___________________________________________________________ Gesendet von Yahoo!
