C++ Winsock 10093 error -


i'm trying build server in c++ can accept multiple number of clients. purpose built winsock wrapper , using threading boost communication each clients.
encountered strange problem when trying accept clients, have loop looks this.

int clientid = 0; listensocket = new socket(sockettype::tcp); listensocket->bind(port); listensocket->listen();  while(running) {     socket *socket = &listensocket->accept();     mutex.lock();     clients.push_back(new client(socket,  clientid));     mutex.unlock();      std::cout << "client id " << clientid << " connected!" << std::endl;      std::cout << wsagetlasterror() << std::endl;      clientid++; }

now, first client accepts fine , wsagetlasterror() returns 0, after first 1 connected, if dont trying connect keep writing in console 10093, means accept() in loop stoppped blocking , reason wont accept properly. read online error caused not calling wsastartup() did called in socket's constructor , did accept in first time.

10093 wsanotinitialised, means wsacleanup() has been called more times wsastartup() has been called.

based on code have provided, appears socket::accept() returning socket instead of socket*. if so, accept() creating temporary socket goes out of scope after socket *socket assigned. chances socket destructor calling wsacleanup() when should not be. calls wsastartup() , wsacleanup() must balanced @ times.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
