development – SystemUpdate() inside my remote event receive will raise “Access denied. You do not have permission to perform this action or access this resource.”

I have the following code inside my remote event receiver (which run on item added):-

 using (ClientContext context = TokenHelper.CreateRemoteEventReceiverClientContext(properties))
              currentItem("OrderAssignToApprover2") = new FieldUserValue() { LookupId = spUser.Id };

now if a non-admin user add an item then the remote event receiver will raise this error on the SystemUpdate():-

Access denied. You do not have permission to perform this action or access this resource.

but if admin user add an item then the remote event receiver will works fine OR if i change the remote event reicever to run using App Permsion, as follow:-

using (ClientContext context = Helpers.GetAppOnlyContext(properties.ItemEventProperties.WebUrl))
              currentItem("OrderAssignToApprover2") = new FieldUserValue() { LookupId = spUser.Id };

so can i assume that the SystemUpdate (unlike Update) require the user to have full control on the site?If this is the case then is there a way to allow non-admin users to execute SystemUpdate?

lua – When PlayerRemoving event is fired, for loop does not work properly

while I was implementing the Backback save feature in my Roblox Game (using game.Players.PlayerRemoving:Connect(), I found that when I used a loop of any form (for, while,etc.), it would not run correctly. Here is a test program which I wrote to observe this issue:

    local testList = {"Hello", ",", "world"}
    for i=1,3,1

However, when this code is ran, all I see in the output window is:


And nothing else.
This issue is causing a lot of issues with the rest of the code, can somebody please help? It would be very useful!

event tracking – Using data-analytics-action within Analytics

I was going through’s source code and noticed pretty much all their links have these attibutes:


Obviously these are used to track where the user is clicking from, however I can’t find any information how to use them within Google Analytics or another Analytics software.

How do I actually set something like this up?

google tag manager – GTM – Bad Event Tracking Code – Pageview Hit must precede event

I’m having trouble finding a GTM error. The error states that Google Tag Manager isn’t receiving the URL/page-name in Google’s Behavior->Landing Pages report before it receives an event.

I’m not sure how to find the offending page and of course, Google can’t tell me the offending page, so trying to use Google’s Tag Assistant would mean testing every single page on the website.

The error appears to be happening on all of the major browsers, so it doesn’t seem to be browser specific.

I tried to lookup one session by matching the session duration with user sessions. The session begins at 11:58 pm and ends at 12:04 am. However, when I use Google’s Tag Assistant, it doesn’t show any errors.

enter image description here

If this were the problem page, it would appear that GTM looses the page name when the session wraps over the midnight hour, but this seems improbable.

enter image description here

How can I properly identify the offending page without using Google Tag Assistant on every single page?

2013 – Are event receivers supposed to handle events of editing the list itself?

I just noticed that our list item event receivers are running when we are updating the list itself. I thought these should only trigger when modifying list items in the list, and not that they would trigger on modifications on the list itself.

Is this expected behavior or have we configured something strange here?

Google isn’t giving me much.

c++ – What do an event system need?

I am building a 2d game engine in c++ for my personal use. This is it if you want to participate in the devolopment:

Now, i decided to start my event system but i don’t know even how an event system works or what it must contains.

I’m thinking about making an event base class which will be inherited by many event types like key press. It will contain type -an enum- and a category signatue -i will use bit fields to mask categories-. it will have also a getters for the type name and bool func that it will recieve a number as a parameter -an enum- which will be used as an index to find if the event is in a specific category and a function that prints the event info -you can override it-.

I will have an event listener -i don’t know how it works it is just my idea- will communicate with the os or the window and it will push an event in an unhandled events vector with the info like mousePos and the event type and the signature and then every update it will be handle events, log info and then clear them.

I feel that there is a lack of idea. So what about my idea and what you can add or do you have an other idea?

Give me recommendations for performance.
Thank you.

java – Error resolving onMouseClicked, event handler is not in the Namespace JavaFx. QuickHelp

I am working on a JavaFx Project and I have encountered an error and I am really not able to resolve this issue.

I have a Home Page and Billing Page. When I try to open the Billing Page from the home page it gives an error (attached below)
The error reads :
Caused by: javafx.fxml.LoadException: Error resolving onMouseClicked='#aboutClicked', either the event handler is not in the Namespace or there is an error in the script.The error image
This error occurs in BillingFXML.

The BillingFXML file has a Label “aboutLabel” which has a “MouseEvent” with handler “aboutClicked”.
This is properly handled in the Controller file of BillingFXML

Please help me as this is my project and I really need to get it done.

The wrong event is started from a drop-down list in an ASP.NET form

I have a main ASP.NET form with multiple drop-down lists and when I open a DDL, the OnSelectedIndexChanged event of another DDL starts and not the one that I open. Besides, other events of other DDL are starting, do you know anything about it?

observer template – NativeScript – Angular Service for watching iOS keyboard event listeners

I am writing an application with NativeScript 6.4.1 and Angular version 8.

There are a series of user interface events in iOS that you can watch to see what the keyboard does:

I wrote a service to watch and subscribe to these changes.

Do you see problems in the code with too many observables and headphones?

Here is my service:

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import * as application from 'tns-core-modules/application';

    providedIn: 'root'
export class iOSKeyboardObserverService {

    public didShow$(): Observable {

        return new Observable((observer) => {

            const iosObserver = application.ios.addNotificationObserver(UIKeyboardDidShowNotification, (notification) => {

            return () => {
                application.ios.removeNotificationObserver(iosObserver, UIKeyboardDidShowNotification);


    public didHide$(): Observable {

        return new Observable((observer) => {

            const iosObserver = application.ios.addNotificationObserver(UIKeyboardDidHideNotification, (notification) => {

            return () => {
                application.ios.removeNotificationObserver(iosObserver, UIKeyboardDidHideNotification);


Usage example:

public isKeyboardShowing: boolean;

constructor(private page: Page, private ngZone: NgZone, private keyboardObserver: iOSKeyboardObserverService) {, (args: EventData) => this.onLayoutChanged(args));
    this.isKeyboardShowing = false;

    if (utils.ios) {

        this.keyboardObserver.didHide$().subscribe((result) => {

        this.keyboardObserver.didShow$().subscribe((result) => {
