sockets - Receive UDP Broadcast fails when change wifi Status Android -


i have receive routine inside asyntask:

                    byte[] message = new byte[1500];                     s = new datagramsocket(null);                     s.setreuseaddress(true);                     s.bind(new inetsocketaddress(dataclass.getdataclass().gggport));                     p = new datagrampacket(message, message.length);                     s.setsotimeout(500);                     s.setbroadcast(true);                     dataclass.getdataclass().setgoout(true);                     s.receive(p);

this code works perfect receive udp broadcast packets in android, have 1 problem: when in android receiving udp packets , turn off access point (no more packets arrives) , after turn on access point, have same problem : timeout.

in situation, if disable wifi , enable wifi works time...

anyone same problem?

you need re-create , re-bind receiving socket each time device's connection status changes.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
