The sample code below works quite well, except it crashes when it exits by typing a character after a while. The crash point is in SendThreadFunc is: for (vector::iterator client = pvClients->begin(); client != pvClients->end(); client++) I get: Exception thrown: read access violation. _Mycont was nullptr. And the callstack is: EventLogConverter.exe!std::_Vector_const_iteratorstd::_Vector_val<std::_Simple_types<CFeedClient > >::operator++() Line 75 ..
