javascript - Samsung TV APP - Update scenes content on network reconnection -


the issue face has loading , reloading of scenes content. app works today not respond network disconnection , reconnection.

for example ,there states ajax-state 200 / fine .. data coming in null -> leads empty scenes.

here snippet controller looks : 

controller.assignevents = function() {     var player = document.getelementbyid('pluginobjectplayer');     player.onconnectionfailed = 'controller.connectionfailed';     player.onnetworkdisconnected = 'controller.networkdisconnected';     player.onstreamnotfound = 'controller.streamnotfound';      $$(document).ajaxerror(function(e, xhr, settings, exception) {        alert('error (' + xhr.status + ') ' + 'in: ' + settings.url + ' | error: ' + exception);        if(xhr.status === 0 || xhr.status === 408 || xhr.status === 504) controller.networkdisconnected();     });      $$(document).ajaxsuccess(function(event, xhr, settings){         alert('ajaxsuccess('+xhr.status+'): ' + settings.url);         if(settings.url.indexof('http:') === 0) {             if(controller.no_network) {                 controller.no_network = false;                 controller.hidenotification();             }         }     }); }  controller.connectionfailed = function() {     alert("stream connection failed");     controller.no_network = true;     controller.shownotification('nema mreze'); }  controller.networkdisconnected = function() {     alert('networkdisconnected');      controller.no_network = true;     controller.shownotification('nema mreze');       if(typeof sf.scene.get('youtube') != 'undefined' && sf.scene.get('youtube').isvideoplaying){         sf.scene.hide('overlay');     } else {          sf.scene.get('content').streamstop(false);     }      sf.scene.get('content').streamstop(false); }  controller.networkresumed = function() {     alert('networkresumed');      controller.no_network = false;      controller.hidenotification();      if(controller.starting){         controller.startup();     } else {         alert("start timeout on resume");         $('#buffering').show();         settimeout(function(){             sf.scene.get('content').streamresume(false);             $('#buffering').hide();         }, 5000);     } }  controller.isconnectionavailable = function() {      if(sf.core.getenvvalue("modelid") == 'sdk') return controller.sdk_network;      var network = document.getelementbyid('pluginobjectnetwork');      var interfacetype = network.getactivetype();      if(interfacetype === -1) return false;      var physicalconn = network.checkphysicalconnection(interfacetype);      if(physicalconn !== 1) return false;      var httpstatus = network.checkhttp(interfacetype);      if(physicalconn !== 1) return false;      return true; }  controller.pollnetwork = function() {     alert('polling network');      var prevstatus = controller.no_network;     controller.no_network = !controller.isconnectionavailable();      if(! controller.no_network && prevstatus) {         controller.networkresumed();     }     else if(controller.no_network && ! prevstatus) {         controller.networkdisconnected();     }      settimeout(controller.pollnetwork, 2000); }

does have idea how fix ? !

i suggest check xhr.responsetext before deciding it's succeed. happened 200 code status response body empty

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
