  I am having some trouble getting this simple code to work: class CreateUserView { public: CreateUserView(void); ~CreateUserView(void); UserController* controller; void showView(); string name; string lastname; string address; string email; string dateOfBirth; }; All i need is to set these attributes in the implementation with getline(). CreateUserView::CreateUserView(void) { } void CreateUserView::showView() { cout << endl << " New User" << endl; cout << "--------------------------" << endl; cout << " Name\t\t: "; getline(cin, name); cout << " Lastname\t: "; getline(cin, lastname); cout << " Email\t\t: "; getline(cin, email); cout << " ===============================" << endl; cout << " 1. SAVE 2.CHANGE 3.CANCEL" << endl; cout << " ===============================" << endl; cout << " choice: "; int choice; cin >> choice; cin.ignore(); controller->createUser_choice(choice); } I keep getting this "Access violation reading location" error at this line: getline(cin, name); what's the best way of assigning a value to an std::string attribute of a class? even name = "whatever" is throwing that error!! thanks

  intrusive_ptr requires intrusive_ptr_add_ref and intrusive_ptr_release to be defined. Why isn't a base class provided which will do this? There is an example here: http://lists.boost.org/Archives/boost/2004/06/66957.php, but the poster says "I don't necessarily think this is a good idea". Why not?
