It looks like a question about how to use C++. 2) Please try hard to send a complete self-contained example, rather than a collection of little bits of code. Often the attempt to create an example will answer the question for you. 3) The declaration of eventList within the class uses std::vector<std::pair<>>, the declaration in the file uses just std::pair, without std::vector. That is probably the root cause of your problem. Ian
