ошибка an attempt was made to access wizardform before it has been created как исправить

Почему проверка WizardForm на null в Inno setup не работает?

Почему это не работает?

Я получаю это исключение:

Я знаю, что WizardForm еще не инициализирован, поэтому я проверяю на ноль, проверка не работает! Что я здесь делаю не так?

Мне нужно подать команду: bcdedit /set recoveryenabled No но это не работает с настройкой Inno. Я попробовал, как показано ниже: [Setup] PrivilegesRequired=admin [Run] Filename: ; Parameters: /c bcdedit.exe /set recoveryenabled No; Но я все равно вижу, что No не применяется. Как вы.

Есть ли другой способ проверить null?

ReferenceError: Cannot access ‘Player’ before initialization

So I’ve been using ES6 style syntax with import/export on Nodejs with the ESM module loader. Everything has been fine until I started getting an error pertaining to imports.

Here’s the error messages:

Here are the files Player (Base class):

And GamePlayer (Child Class):

And the heirarchy of the project:

How can I fix this import issue, unless this is something else?

3 Answers 3

I went to the Node.JS forums and asked what could be the issue. Not a babel issue at all, just circular dependencies. For example:

Sorry there wasn’t nearly enough information to be able to figure this one out. I got a lot of help on the node.js github and someone looked through my project on github and ended up finding an instance where two modules pointed at each other.

As I mentioned in a comment for another answer, import can be used in a «circular» way, but Node.js can’t always untangle the dependencies.

In my case it had no problem with a class in one file and a subclass of that in another file, where both of them import each other, and it’s hard to say exactly where it got too complicated, but this is a simplified version of what I had that broke it:

I’m using the same code for browsers and server-side Node.js, so I was also transpiling it with Babel, which handled everything fine. But Node may have other constraints that make it more difficult, because, at least as far as importing is concerned, it was on a different track from browsers (and others), and is now trying to bridge the gap. And also the knot may be more tangled than it appears to the naked eye.

In the end I ditched the most circular part of my pattern, which was the part where I refer to the Thing subclasses within Thing itself. I extracted that into a «factory-like» pattern, where the factory knows about the Thing subclasses, but the Thing and its subclasses don’t need the factory.

Fix: An Attempt Was Made to Access a Socket in a Way Forbidden by its Access Permissions

Some users reported receiving the “an attempt was made to access a socket in a way forbidden by its access permissions” error when trying to run the ipconfig/renew command in CMD in order to repair their network connection. Other users report that this issue is occurring when they try to start an Apache server. However, almost all affected users report that the issue started occurring after a Windows automatic update has been installed.

An attempt was made to access a socket in a way forbidden by its access permissions

What is causing the attempt was made to access a socket in a way forbidden by its access permissions error?

We investigated this particular issue by looking at various user reports and the repair strategies that they used to get the issue resolved. From what we gathered, there are several different scenarios that will trigger the apparition of this issue:

If you’re currently struggling to resolve the issue, this article will provide you with a list of verified steps that other users in a similar situation have used to get the issue resolved. Below you have several methods that other users encountering the same error message have used to fix the problem.

For the best results, follow the potential fixes below in order until you encounter one that is effective for your particular scenario.

Method 1: Disabling Internet Connection Sharing

This one is quite a peculiar culprit because internet Sharing on Windows uses a few different ranges of ports that aren’t necessarily reported to Netstat or a similar tool.

However, several users reported that for them, the issue was resolved permanently after they disabled Internet Connection Sharing. There are two different ways that will allow you to disable Internet Connection Sharing on Windows. Follow whichever methods are more convenable for you:

Disabling Internet Connection Sharing via Control Panel

Disabling the Internet Connection Sharing Service

Method 2: Uninstalling your 3rd party AV or whitelisting the connection

A lot of users have pointed out that 3rd party security suits should be checked to confirm that they’re not interfering with the SMTP connections. McAfee, BitDefender, and Avast are confirmed to blocked certain ports used by localhost connections. With certain ports, this is standard behavior in order to prevent mas mail attacks.

As some users have reported, an overprotective firewall or a similar security filtering tool can be responsible for causing the “an attempt was made to access a socket in a way forbidden by its access permissions” error.

You can typically resolve this issue by whitelisting the connection that is being blocked from your AV settings. Keep in mind that the steps of establishing a whitelist rule will be different depending on your security solution client.

General > Exclusion.» width=»789″ height=»534″ srcset=»https://cdn.appuals.com/wp-content/uploads/2018/11/exclusion-list.png 789w, https://cdn.appuals.com/wp-content/uploads/2018/11/exclusion-list-150×102.png 150w, https://cdn.appuals.com/wp-content/uploads/2018/11/exclusion-list-300×203.png 300w, https://cdn.appuals.com/wp-content/uploads/2018/11/exclusion-list-768×520.png 768w, https://cdn.appuals.com/wp-content/uploads/2018/11/exclusion-list-220×150.png 220w» sizes=»(max-width: 789px) 100vw, 789px»/> In Avast, you can add a connection to the exclusion by going to Settings > General > Exclusion.

If you’re having trouble identifying the connection that is being blocked, you can temporarily uninstall your 3rd party antivirus and see if the issue is resolved.

Note: Keep in mind that disabling the real-time protection of your AV will not help you reach a conclusion since the same rules will remain firmly in place.

If you decide to uninstall your 3rd party AV, you can follow this step by step guide (here). In the event that this method wasn’t applicable or you’ve determined that the 3rd party client was not responsible for the error, move down to the next method below.

Update: IP blocking clients such as PeerBlock might automatically block an IP that is involved in the operation that is failing. Several users have reported that the issue was automatically resolved after creating a rule exception or uninstalling the IP blocking software.

Method 3: Adding an exclusion to the Windows Firewall

As it turns out, the integrated Windows Firewall can also be responsible for the “an attempt was made to access a socket in a way forbidden by its access permissions” error.

Several affected users reported that they managed to get the issue resolved after allowing the program that is displaying the error to communicate through Windows Firewall. This method is typically reported to be successful with users encountering the error with SQL server, but you can adapt the steps below to accommodate a different program.

Here’s a quick guide with what you need to do:

Note: In the event that you can’t find the program listed under Allowed apps and features, click the Allow another app button and select it manually by clicking on Browse.

If you’re still seeing the same error, move down to the next method below.

Method 4: Restarting the Internet Information Services (IIS)

Several users have reported that the issue was resolved after they restarted the Internet Information Services (IIS) from an elevated Command Prompt window.

But keep in mind that restarting the IIS servers will drop all internet services including FTP, SMTP and NNTP and any data held in the applications handling the connections is lost.

Here’s a quick guide on how to do this:

If you’re still seeing the “an attempt was made to access a socket in a way forbidden by its access permissions” error, move down to the next method below.

Method 5: Using a previous system restore point

After finding that several other repair strategies where ineffective, some users have finally managed to connect to the internet without being blocked by the “an attempt was made to access a socket in a way forbidden by its access permissions” error by reverting their machine state to a previous point in time using System Restore.

If you only started to see this error recently and you’re lucky enough to have a system restore point that is dated before you started struggling with this issue, then these following steps should help you resolve the issue for good:

Method 6: Disconnecting from the VPN network

Some affected users have discovered that in their case, the issue was caused by a VPN client. It turns out that the “an attempt was made to access a socket in a way forbidden by its access permissions” error can also be caused by a VPN client that is causing some involved localhost connections to fail.

To test whether this theory holds true in your case, simply disconnect from the VPN network and see if the issue is resolved. If the error message is no longer occurring while VPN is disconnected, you need to look for a different VPN client or at least keep it disabled while performing a certain task that will trigger the error.

I am trying to use DI for my dbContext with MVC6/EF7 RC1.

I am instantiating my ContextTest (inherited from dbcontext) using [FromServices] attribute in the constructor of my TestService class

Sporadically i am running into below exception

«An attempt was made to use the context while it is being configured. A DbContext instance cannot be used inside OnConfiguring since it is still being configured at this point.»

My 2 cents: Something to with Async calls (DI injects only 1 instance and i am trying to fire 3 queries in parallel.

Any chance you could provide a project that we can use to reproduce the issue? There is nothing obviously wrong in the code you provided.

My 2 cents: Something to with Async calls (DI injects only 1 instance and i am trying to fire 3 queries in parallel.

Are you referring to this code? If so, the queries aren’t running in parallel since you have await’ed the calls (which is the correct thing to do since you can’t run parallel operations on the same context instance).

Closing as we have not heard back

dazinator commented Feb 26, 2016

I am now also seeing this error, I’ll see if I can share a repro once I get some time. Maybe its something I am doing wrong, not sure yet.

dance commented Apr 11, 2016

@valcs007 you are using DbContext in TestService, which is possibly singleton and you end up using the one and only DbContext in your whole app. I’ve ran into same problem due to inaccurate design of my services: controller used some service injected through constructor to actually perform business logic, while this service was a singleton with DbContext injected through constructor again. So I ended up trying to operate on the same DbContext in every request. When there were few requests, it worked fine, but under some pressure bunch of exceptions begin to occur like

Be careful and pay attention to register all of your services with correct DI lifetime management. Do not inject Scoped and Transient services into singletons. P.S. I hope my comment will someday help someone 🙂

dooreelko commented Jun 9, 2016

I’d like to reopen this.
This can happen if for instance the web api controller has two methods (or same method in parallel) that are invoked in parallel using the same DbContext. Since the DbContext is lazily initialized, it will happen only when a user attempts a query, bringing a race condition with the exception in question.

So, imo, the DbContext::InitializeServices (or even DbContext::InternalServiceProvider::get) should be properly locked for the same instance and not throwing the exception. The second call should be simply blocked until the first finishes initialisation.

Ошибка runtime error. Как ее исправить?

Ошибку runtime error могут вызвать множество причин и одна из самых распространенных — это установка новых версий программ поверх уже установленных, что приводит к появлению ошибок в системном реестре. Другая распространенная причина — связана с деятельностью различных вирусов, троянов и рекламных шпионов, которые проникают на ваш компьютер и могут удалить, либо модифицировать критически важные файлы вашей операционной системы.

Ошибку runtime error достаточно легко исправить. В 99% случаев, любой чистильщик реестра поможет восстановить удаленные файлы, либо исправить поврежденные. Чистильщики реестра специально разработаны для исправления большинства ошибок, связанных с runtime error, в том числе и runtime error 91, runtime error 13 и многих других, т.к. они проверяют целостность файловой системы.

Если вы ищете как runtime error исправить — вы попали по адресу. Причин появления таковой может быть огромное множество. Чаще всего причина состоит в том, что выходит новая версия того или иного приложения/игры и она устанавливается прямо поверх старой. Хотя это далеко не единственная ситуация, которая может вызвать ее появление.

Способ №1. CCleaner

Самое простое решение заключается в том, чтобы воспользоваться программой для чистки реестра. Как это работает?

Все просто – чистильщик реестра, собственно, и предназначен для того, чтобы исправлять всевозможные проблемы, вроде той, которую рассматриваем мы, систематизировать файлы и добавлять то, чего недостает ему для нормальной работы.

Лучшей по праву считается CCleaner, хотя вы можете воспользоваться и другой.

Способ №2. DirectX

Вполне вероятно, что ее появление вызывают какие-то проблемы с DirectX. Возможно, какие-то файлы исполняемых библиотек были повреждены или же существующие библиотеки банально устарели.

В любом случае, лучше всего просто установить наиболее актуальные варианты и, опять же, перезагрузить компьютер.

Для этого зайдите на сайт Microsoft, на страницу с возможностью скачать DirectX (вот ссылка). Запустите скачанный файл и выполните все действия, подразумевающие установку исполняемых библиотек. Здесь нет никаких особых рекомендаций – обычная. Если после установки и перезагрузки компьютера ошибка не исчезла, идем дальше.

Способ №3. Visual C++

Бывают в данном случае и другие ситуации, когда установленная C++ попросту не подходит для вашей операционной системы. Ниже приведена таблица с вариантами, которые подходят для разных версий ОС.

Так вот, в зависимости от того, какая у вас ОС, вам следует скачать и инсталировать на свой компьютер C++2008, C++2010, C++2015 или новее.
