I have the following code:
var c = null;
c = Titanium.Network.createHTTPClient();
var url = 'example.com';
c.open('GET', url);
Titanium.API.log('info', url);
c.onload = function()
{
Titanium.API.log('info', 'onload');
setInterval(getPeople(), 5000);
};
c.send();
The code should access the getPeople() function every 5 seconds, but it does not. In fact, the application exists prematurely.
what Im I doing wrong?
Try either:
setInterval(getPeople, 5000);
or:
setInterval("getPeople()", 5000);

I am trying to simply record the webrtc video using what I though was a standard example. The library is here: https://github.com/muaz-khan/RTCMultiConnection
rtcMultiConnection.onstream = function(e) {
var mediaElement = getMediaElement(e.mediaElement, {
onRecordingStarted: function(type) {
// www.RTCMultiConnection.org/docs/startRecording/
rtcMultiConnection.streams[e.streamid].startRecording();
},
onRecordingStopped: function(type) {
// www.RTCMultiConnection.org/docs/stopRecording/
rtcMultiConnection.streams[e.streamid].stopRecording(function(blob){
console.log("test");
console.log(blob);
});
}});}
I can follow the steps through the function calls, the issue is that the callback is never run from recordrtc.js....
It goes to line 100 of https://github.com/muaz-khan/RecordRTC/blob/master/RecordRTC.js
There it runs:
mediaRecorder.stop(_callback);
Which never calls the callback....
Even calling functions directly doesn't work:
console.log(rtcMultiConnection.streams[e.streamid].audioRecorder.getBlob());
console.log(rtcMultiConnection.streams[e.streamid].videoRecorder.save("a.png"));
I am wondering if two different versions of recordrtc and rtcmulticonneciton are interacting.... Any ideas? Maybe an older recordrtc, but I can't find an older version
Please use blob.video:
var stream = connection.streams['stream-id'];
stream.stopRecording(function(blob) {
var h2;
if (blob.audio) {
h2 = document.createElement('h2');
h2.innerHTML = 'Open recorded ' + blob.audio.type + '';
div.appendChild(h2);
}
if (blob.video) {
h2 = document.createElement('h2');
h2.innerHTML = 'Open recorded ' + blob.video.type + '';
div.appendChild(h2);
}
});

Here is the actual documentation:
http://www.rtcmulticonnection.org/docs/startRecording/
Please make sure that:
You are using v2.2.2
You called startRecording first
For v3, you can directly use the RecordRTC:
connection.onstream = function(event) {
recordStream(event.stream);
};
function recordStream(stream) {
if (!!window.recorder) return;
window.recorder = RecordRTC(stream, {
type: 'video'
});
recorder.startRecording();
}
btnStopRecording.onclick = function() {
if (!window.recorder) return;
recorder.stopRecording(function() {
var blob = recorder.blob;
// or dataURL
recorder.getDataURL(func_callback);
});
};
btnStartRecording.onclick = function() {
var stream = connection.attachStreams[0];
recordStream(straem);
// or
var stream = connection.streamEvents['stream-id'].stream;
recordStream(straem);
};
Above snippet can be used within v2.2.2 as well.
I'm using System.Windows.Forms.WebBrowser in console application to render a web page then invoke scripts on it. To render the web page, I use Application.DoEvents to load and execute scripts.
However sometime the app hangs on calling Application.DoEvents. I found no reason. I don't think I'm creating deadlock on the event loop.
Many people on the web says that one should not use Application.DoEvents at all because it creates more problems than it solves. So I'm thinking there must be an alternative to it. But I've searched a lot and find no alternative to Application.DoEvents.
Does anyone know one?
Any information is appreciated. Thank you in advance!
Thanks to Noseratio's help, I finished drafting my code but still there's freezing issue.
Take following code as example(code is too long so I pasted it on pastebin): http://pastebin.com/DkDcrirU
When you run this code, occasionally there will be at least one window fail to close. And if you attach to the frozen process, you will find the code stuck at following line(indicated by ">>>"):
public static bool NavigateLoadAndRender(WebBrowserContext browserContext, string url, TimeSpan loadTimeout, TimeSpan renderTime, out string errMsg)
{
ForceInitActiveXInstance(browserContext);
object axi = null;
Func<Uri> getBrowserUri = null;
Action<Uri> navigateBrowser = null;
Func<IHTMLDocument2> getBrowserDoc = null;
switch (browserContext.WebBrowserType)
{
case WebBrowserTypeEnum.Forms:
{
var browser = browserContext.GetWebBrowserAsFormsType();
getBrowserUri = () => browser.Url;
navigateBrowser = u =>
{
var finished = false;
browserContext.SyncContext.Post(state =>
{
browser.Navigate(u);
finished = true;
}, null);
while (!finished) Thread.Sleep(DefaultConfig_SyncContextPostCheckInterval);
};
getBrowserDoc = () =>
{
IHTMLDocument2 doc = null;
bool finished = false;
browserContext.SyncContext.Post(state =>
{
doc = (IHTMLDocument2)browser.Document.DomDocument;
finished = true;
}, null);
>>> while (!finished) Thread.Sleep(DefaultConfig_SyncContextPostCheckInterval);
return doc;
};
axi = GetActiveXInstance(browserContext);
}
break;
case WebBrowserTypeEnum.Wpf:
{
var browser = browserContext.GetWebBrowserAsWpfType();
axi = GetActiveXInstance(browser);
getBrowserUri = () => browser.Source;
navigateBrowser = u =>
{
var finished = false;
browserContext.SyncContext.Post(state =>
{
browser.Navigate(u);
finished = true;
}, null);
while (!finished) Thread.Sleep(DefaultConfig_SyncContextPostCheckInterval);
};
getBrowserDoc = () =>
{
IHTMLDocument2 doc = null;
bool finished = false;
browserContext.SyncContext.Post(state =>
{
doc = (IHTMLDocument2)browser.Document;
finished = true;
}, null);
while (!finished) Thread.Sleep(DefaultConfig_SyncContextPostCheckInterval);
return doc;
};
axi = GetActiveXInstance(browserContext);
}
break;
default: throw new ArgumentException("unknown browser type", browserContext.WebBrowserType.ToString());
}
var success = NavigateLoadAndRender(
axi, url,
getBrowserUri,
navigateBrowser,
//() => DoEvents(browser),
getBrowserDoc,
loadTimeout, renderTime, out errMsg);
return success;
}
Anyone knows what's happening?
I am trying to use your api in a custom app with imported users.
Everything works fine (auth_token, login, call initiation) , but when the callee should get a response and add the remotestream nothing happens. no errors get shown in the console.
I would appreciate if someone takes a look at the code and tells me what i m missing.
I tried the vline demo at https://freeofcinema.vline.com and it worked with the same browsers and conditions between the two computers. In my app it is a http , but i tried it also with https, and the same problem came up. This is some simplified code i used to test the api.
var Streams = [];
var Vsession = null;
var Vline = (function(){
var Client;
var authToken;
var service_id = 'freeofcinema';
var profile = null;
var Person;
var Calls = [];
var onMessage = function(event){
//alert('message');
var msg = event.message, sender = msg.getSender();
console.log(sender.getDisplayName() +'sais: '+ msg.getBody());
console.log(event);
}
var onMediaSession = function(event){
console.log(event);
var mediaSession = event.target;
InitSession(mediaSession);
}
function Call(mediaSession) {
mediaSession.
on('change', alert_info);
}
function alert_info(b){
console.log(b);
}
function InitSession(mediaSession){
mediaSession.on('mediaSession:addRemoteStream', function(event) {
alert('addRemoteStream');
});
mediaSession.on('mediaSession:addLocalStream', function(event) {
alert('addLocalStream');
});
mediaSession.on('mediaSession:removeLocalStream mediaSession:removeRemoteStream', function(event) {
console.log('removedStream');
});
Calls.push(new Call(mediaSession));
}
return {
init : function(){
if(profile){
return;
}
profile = {
"displayName" : //some getusrname function...
};
$.post('vtoken.php',{//get auth token
id : Comm.Voip_user().id
},function(data){
authToken = data;
Client = vline.Client.create({
"serviceId": service_id,
"ui" : true
});
Client.on('recv:im', onMessage , this);
Client.on('add:mediaSession', onMediaSession, this);
Client.on('login', function(e) {
Vsession = e.target;
//alert('loged in');
});
Client.login(service_id, profile, authToken);
});
},
getPerson : function(id){//id of user to call
if(Vsession){
Vsession.getPerson(id).
done(function(person){
Person = person;
Vsession.startMedia(id);
});
}
}
}
}());
Thank you for your response.
I tried with one user from the app, and another from the https://freeofcinema.vline.com, and the same problem occured. Also the call (in pending state) gets terminated after a short while..
When passing ui:true when creating the client, you do not have to handle the media sessions yourself. Just comment the line Client.on('add:mediaSession', onMediaSession, this); and it should just work.
I have a fairly simple controller that gets a simple json list of objects ...
function ProductGroupsCtrl($scope, $http, $routeParams, sharedService, popupService) {
$scope.list = null;
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
$scope.selectItem = function (item) {
$scope.selectedItem = item;
$scope.selectedItemJsonString = JSON.stringify(item);
//alert(JSON.stringify(item));
};
$scope.closePopup = function () {
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
};
// sharedService.prepForBroadcast($routeParams.anotherVar);
$http({
method: 'GET',
url: '/ProductGroup'
}).success(function (data) {
$scope.list = data;
}).
error(function (data) {
$scope.message = 'There was an error with the data request.';
});
}
I then try to mock the request in the test class:
var scope, ctrl, $httpBackend, sharedServiceMock = {}, popupServiceMock = {};
beforeEach(inject(function (_$httpBackend_, $rootScope, $controller) {
$httpBackend = _$httpBackend_;
$httsypBackend.expectGET('/ProductGroup').
respond([{
ProductGroupID: 5,
MenuTitle: "Promotional Products",
AlternativeText: "Coming soon - a collection of environmentally friendly Promotional Products",
OrdinalPosition: 5,
Active: false
}]);
scope = $rootScope.$new();
ctrl = $controller(ProductGroupsCtrl, {
$scope: scope,
$http: $httpBackend,
sharedService: sharedServiceMock,
popupService: popupServiceMock
});}));
However I receive an error in the testacular window object undefined. What have I done wrong here?
Found the answer. If I remove the error callback function from the $http.get method then it works, i.e. remove the following ...
error(function (data) {
$scope.message = 'There was an error with the data request.';
}
I have to say Angular sure is a steep learning curve for someone who is not a day to day JavaScript programmer (although I seem to be doing more and more). Thanks for the help anyway KatieK :-)
I have used Ti.Network.createHTTPClient in Titanium and see that the control goes neither inside onLoad nor onError. What could be the reason?
var loader = Titanium.Network.createHTTPClient();
loader.onload = function() {
alert("Hello");
}
loader.onError = function(e)
alert("Error: " + e.error);
}
Add these 2 lines to make it work! You did not send the request, nor did you send the URL
// add url in here
loader.open("GET",'[URL HERE]');
// Send the request.
loader.send();
var xhrSitelogin = Titanium.Network.createHTTPClient();
xhrSitelogin.open('POST', webservice_url);
xhrSitelogin.send({
method : "userlogin",
username : username,
password : password
});
xhrSitelogin.setTimeout(10000);
xhrSitelogin.onerror = function() {
showAlertBox('Service timed out. Please try again.');
//Hide Indicator
};
xhrSitelogin.onload = function() {
alert(this.responseText);
//RESPONSE RECEIVED
};
Vote Up or mark best if you consider it help full.
Hi dosth try with this am not sure it will work if it work i will be happy
var taskRequest = Titanium.Network.createHTTPClient();
var api_url = 'http://myawesomeapi.heroku.com/users/' +
Ti.App.Properties.getString("userID") + '/tasks';
taskRequest.onload = function() {
var tasks = [];
// code populating the tasks array
alert(tasks);
callback( tasks ); // invoke the callback
}
taskRequest.open('GET', api_url, false);
taskRequest.setRequestHeader('Content-Type', 'application/json');
taskRequest.send();
<....>
loader.open("POST/GET","URL");
loader.onload(response){
//get the response
console.log(this.responseText);
};
loader.send();
Use this pattern.
If you need to set any header then use loader.setRequestHeader("Content-Type", "application/json; charset=utf-8"); after the open()/before onload() and send()
