Before the iOS8 will be released, I downloaded iOS8 SDK to watch how my application will be work. Sometimes my app need to download data from server and I use NSUrlSession for it. And now, when app preparing session for downloading, appears the next warning:
+backgroundSessionConfiguration: is deprecated. Please use +backgroundSessionConfigurationWithIdentifier: instead.
After it my app crashes with the next exception:
Unable to cast object of type 'MonoTouch.Foundation.NSUrlSessionTask' (Objective-C type: '__NSCFBackgroundDownloadTask') to type 'MonoTouch.Foundation.NSUrlSessionDownloadTask'.
Additional information:
Selector: URLSession:downloadTask:didFinishDownloadingToURL:
Method: Microsoft.Synchronization.ClientServices.NSUrlDownloadDelegate:DidFinishDownloading (MonoTouch.Foundation.NSUrlSession,MonoTouch.Foundation.NSUrlSessionDownloadTask,MonoTouch.Foundation.NSUrl)
Code for creating NSUrlSession:
NSUrlSessionConfiguration sessionConfiguration = NSUrlSessionConfiguration.BackgroundSessionConfiguration(urlSessioinId);
NSUrlDownloadDelegate downloadDelegate = new NSUrlDownloadDelegate();
NSUrlSession downloadSession = NSUrlSession.FromConfiguration(sessionConfiguration, downloadDelegate, new NSOperationQueue());
Thanks for any help!
I have use following to solve this error in Objective-C :
NSURLSessionConfiguration *sessionConfig;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0f)
{
sessionConfig =[NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:#"downloads"];
}
else
{
sessionConfig = [NSURLSessionConfiguration backgroundSessionConfiguration:#"downloads"];
}
This should work.
if(UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
configDownload = NSUrlSessionConfiguration.CreateBackgroundSessionConfiguration(sessionId);
}
else
{
configDownload = NSUrlSessionConfiguration.BackgroundSessionConfiguration(sessionId);
}

I am trying to enable fullscreen in my game written in Phaser 3.
I am doing it from Scene class via
this.game.scale.startFullScreen();
but getting error in f12 browser console
Uncaught TypeError: this.game.scale.startFullScreen is not a function
at TitleScene.<anonymous> (TitleScene.js:23)
at InputPlugin.emit (phaser.js:2025)
at InputPlugin.processDownEvents (phaser.js:167273)
...
In docs ScaleManager class has startFullScreen method.
Why console tells me it doesn't?
This is the full code of TitleScene.js:
export class TitleScene extends Phaser.Scene {
constructor ()
{
const config =
{
key: 'TitleScene'
}
super(config);
}
preload ()
{
this.load.image('Title', 'assets/Title.png');
}
create ()
{
this.background = this.add.image(960, 540, 'Title');
this.input.manager.enabled = true;
this.input.once('pointerdown', function () {
this.scene.start('MainScene');
this.game.scale.startFullScreen(); // here is the error
}, this);
}
}
There are two problems prevented me from resolving this problem:
I followed examples from here
https://www.phaser.io/examples/v2
But I am using the third version Phaser. And everyone who uses the same must follow examples from here
https://www.phaser.io/examples/v3
You must pay attention to url while using their site with examples. Both pages are the same from the first look. But urls are different. Also there are warning after each example using the second (old) version of engine.
And finally this function name is not startFullScreen but startFullscreen :)
I'm trying to build some tests for my bot dialogs. I'm using the same test code (and modified test data) with two different bots with the identical dialog names. As such, the test.js file is the same for both bots. However, when I try to run my tests via Mocha on the second bot, I am getting an Error: DialogSet.add(): Invalid dialog being added. message for each test. This does not happen with my first bot. I even tried replacing the dialog file in the second bot with the one from the (working) first, and I still got the same error. As such I can't find anything different between the bots. I even replaced all of the files in question (the test, the test data/conversation, and the dialog itself) with the files from the first bot and still got the same error. Lastly, all botbuilder packages and other dependencies are the same version between the bots. I'm at a loss here...anyone have any ideas?
Here is the dialog that is being called. I left out the actual dialog steps but that shouldn't be relevant to the issue since all of the Dialog add activity happens in the constructor.
const { TextPrompt, ChoicePrompt, ConfirmPrompt, ChoiceFactory, ComponentDialog, WaterfallDialog, DialogSet, DialogTurnStatus } = require('botbuilder-dialogs');
const { VistaServiceHelper } = require('../helpers/vistaServiceHelper');
const { TrackingServiceHelper } = require('../helpers/trackingServiceHelper');
const { CosmosDbStorage } = require('botbuilder-azure');
const LINE_PROMPT = 'linePrompt';
const ORDER_PROMPT = 'orderPrompt';
const CRITERIA_PROMPT = 'criteriaPrompt';
const SEARCH_CRITERIA = ['GO', 'PO'];
const WATERFALL_DIALOG = 'waterfallDialog';
const CONFIRM_PROMPT = 'confirmPrompt';
// Static texts
const escalateMessage = `Escalation message here`
const msDay = 86400000;
class viewOrderDialog extends ComponentDialog {
constructor(dialogId, userDialogStateAccessor, userState) {
super(dialogId);
this.addDialog(new ChoicePrompt(CRITERIA_PROMPT));
this.addDialog(new TextPrompt(ORDER_PROMPT));
this.addDialog(new TextPrompt(LINE_PROMPT, this.validateLineNumber));
this.addDialog(new ConfirmPrompt(CONFIRM_PROMPT));
this.addDialog(new WaterfallDialog(WATERFALL_DIALOG, [
this.requestOrderNumber.bind(this),
this.selectSearchCriteria.bind(this),
this.displayLineItems.bind(this),
this.displayLineStatus.bind(this),
this.loopStep.bind(this)
]));
this.initialDialogId = WATERFALL_DIALOG;
this.integrationLog = new CosmosDbStorage({
serviceEndpoint: process.env.ACTUAL_SERVICE_ENDPOINT,
authKey: process.env.ACTUAL_AUTH_KEY,
databaseId: process.env.DATABASE,
collectionId: 'integration-logs'
});
this.queryData = {};
} // End constructor
I was able to fix this by deleting the botbuilder-testing folder inside the project's node_modules folder and rerunning npm install botbuilder-testing (even though I had already confirmed version in package.json and package-lock.json were showing latest version and had run npm install and npm update).
It appears this did stem from some sort of versioning issue and for whatever reason, only completely deleting the folder and reinstalling fixed it.
You may want to also verify the version of botbuilder inside your package.json file, because all of this packages must be at the same version
Ex:
"botbuilder": "~4.10.3",
"botbuilder-ai": "~4.10.3",
"botbuilder-dialogs": "~4.10.3",
"botbuilder-testing": "~4.10.3",
I Believe the accepted answer does not work in all cases . the correct answer would be to have the same botbuilder and botbuilder-testing versions .
I had the same problem and putting the same versions (or at least not putting a botbuilder-testing version above botbuilder worked)
Example
Here are example versions that work together :
"botbuilder": "~4.13.6",
"botbuilder-dialogs": "~4.13.6",
"botbuilder-testing": "^4.13.6",

any help?
1)If your trying to run redis on windows set accepts only two arguments cause the redis version issue
2)try latest version of redis on linux it will work
Try installing this version of Redis on windows from the following link. You can find more information here https://github.com/ServiceStack/redis-windows
This link provides three options to install Redis on windows
Option 1) Install Redis on Ubuntu on Windows
Option 2) Running the latest version of Redis with Vagrant
Option 3) Running Microsoft's native port of Redis
I personally prefer option 3.
Hope this helped. Thanks.
all of my codes look like this: [...]
It's not important how all of your code looks like. It's important how the specific line that caused the problem looks like but unfortunately you didn't include it.
The errors that you provided include some files and line numbers but you seem to have removed the ones that are related to your code. If you read those messages carefully then you should be able to know what lines those errors are related to and focus on those lines.
If the errors show up on a server and not on your desktop then I would suspect that maybe you're trying to use some environment variables or files on the file system to populate some variables in your program, and those are not available on the server resulting in putting undefined there.
You will surely find the problem when you add console.log() statements to every place where you want to access Redis so that you first print it and then call to Redis. That way at least you will know what data is causing the problem. I suspect that you are having some undefined values or something like that.
Remember that JSON.stringify(undefined) returns undefined instead of a valid JSON string. Something like that may be causing problems. Adding debug messages will help to narrow it down.
Some extra advice: You can use prefix parameter of the redis module then you will not have to add startKeyForRedis+ all over the place. You can set a prefix once and have it prepended automatically. See the docs:
https://www.npmjs.com/package/redis
I was doing learning to use KUE a nodejs library for job scheduling that uses redis for saving data.
I got this error while running client.js(that puts jobs in queue) and worker.js(that process the schedule jobs).
I was running worker before running the client and that is why this happened.
I reversed the order and everything went fine!
To fix this error on windows Redis from v.3 required.
That's why I've took zipped release 3.0.504 from here and now all is working.
Quite simple.
I have faced similar type of error which was because of older version of Redis. This is compatibility issue which fixes a bug in Redis after Redis 2.6.12. Make sure you install recent version of Redis v3.X.
As an experiment, I'm trying some stuff out with dart and easyrtc. I started at porting this (it is normally served through a nodejs server, found here) to a dart version and this is what I made from it
EDIT: I found out which part of the code is causing the error. It is the data object proxy which the for loop is unable to run through. Normally, the setRoomOccupantListener function gives as parameters the name of the room and an object with all the peers connected to the room. I have made a screenshot of the object layout in normal javascript as how it looks when I debug in chrome, found here.
function connect() {
easyrtc.setRoomOccupantListener(convertListToButtons);
}
function convertListToButtons (roomName, data, isPrimary) {
clearConnectList();
var otherClientDiv = document.getElementById("otherClients");
for(var easyrtcid in data) {
var button = document.createElement("button");
button.onclick = function(easyrtcid) {
return function() {
performCall(easyrtcid);
};
}(easyrtcid);
var label = document.createTextNode(easyrtc.idToName(easyrtcid));
button.appendChild(label);
otherClientDiv.appendChild(button);
}
}
And here is the screenshot when i debug the dart code in chromium
void connect() {
easyrtc.setRoomOccupantListener(convertListToButtons);
}
void convertListToButtons(roomName, data, isPrimary) {
clearConnectList();
var otherClientDiv = querySelector("#otherClients");
for (var easyrtcid in data) {
var button = document.createElement("button");
button.onClick.listen((event) {
performCall(easyrtcid);
});
button.appendText(easyrtc.idToName(easyrtcid));
otherClientDiv.append(button);
}
}
This is the error I get:
Class 'Proxy' has no instance getter 'iterator'.
NoSuchMethodError: method not found: 'iterator' Receiver: Instance of 'Proxy' Arguments: []
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:45)
#1 P...<omitted>...7)
Am I missing something simple here or is this some kind of incompatibility? Thank you.
I see you can use import package:js/js.dart'; too. I don't know how to use it
You could try
import 'dart:js' as js;
https://www.dartlang.org/articles/js-dart-interop/
This looks weird too
easyrtc = js.context.easyrtc; // <== here you have context 'easyrtc'
easyrtc.easyApp('easyrtc.audioVideo', 'selfVideo', new js.JsObject.jsify(['callerVideo']), loginSuccess, loginFailure);
// and here again 'easyrtc.audioVideo', I guess this is one to much
try
easyrtc.easyApp.callMethod('audioVideo', ['selfVideo', js.JsObject.jsify(['callerVideo']), loginSuccess, loginFailure]);
where 'audioVideo' is the called method and the rest are arguments
easyrtc.callMethod('easyApp', ['audioVideo', 'selfVideo', js.JsObject.jsify(['callerVideo']), loginSuccess, loginFailure]);
where 'easyApp' is the called method and the rest are arguments.
If you can add how the code would look in JavaScript I could create better examples.
Like dart:js package:js doesn't handle directly Dart List. So the following line :
easyrtc.easyApp('easyrtc.audioVideo', 'selfVideo',
['callerVideo'], loginSuccess, loginFailure);
should be :
easyrtc.easyApp('easyrtc.audioVideo', 'selfVideo',
js.array(['callerVideo']), loginSuccess, loginFailure);

Accessing a string created by an Error's getStackTrace function is resulting in very unusual behaviour in the FlashDevelop IDE.
package
{
import flash.display.Sprite;
public class Main extends Sprite
{
public function Main():void
{
print("Start");
var err:Error = new Error();
var stack:String = err.getStackTrace();
print(stack);
// also occurs when this is replaced with stack.length or stack[0]
print("End");
}
private function print(input:*):void
{
trace(input);
trace("---");
}
}
}
When run in flash CS4 that outputs
Start
---
Error
at Main()
---
End
---
But when run in FlashDevelop (replacing trace() with FlashConnect.trace()) it outputs
Start
---
Is that a bug, or is it FlashDevelop handling errors in a different way intentionally?
If it is the latter is there a workaround to access the stacktrace of an error?
I managed to fix this by switching to using a dubugging version of the flash player, i hope this helps anyone else with this problem.
instructions for specifying a debug player
Make sure you are compiling in Debug configuration and you may have to enable (set True) "Verbose Stack Trace" in your Project Properties > Compiler Options
