What you are really asking is how to implement a function after a promise is done. If so, then making the function an Async function will do the trick. For information on async-await check out Async/await. 2 solved Async-Await or Promises with JavaScript functions [closed]
So, where you call GetSingleLocationInfo, you are calling an async method. GetSingleLocationInfo calwill therefore run as far as the await statement then return stright to the caller, before the it httpClient.GetStringAsync(hereNetUrl); has returned. To fix this, you need to await on your call GetSingleLocationInfo before trying to access the variable. 1 solved why instance variable … Read more
Calling Run Initializing the tasks from within the constructor was the crime comitted.. Just by moving it to the constuctor of the Control .. it was solved! 1 solved All tasks are blocked from ContinueWith [C#].. while calling Task.Delay waiting a value that should be changed by other tasks
As you can tell from some of the comments, multithreaded code is serious business. It’s best to follow a proven pattern, e.g. producer-consumer, or at least use an established synchronization primitive like a monitor or semaphore. Because I might be wrong. It is easy to go over code that you came up with yourself and … Read more
This code will not compile as c# will not allow you to have methods and properties that are not defined in a class/type. Really you need to have a class and that class should have a constructor and that constructor should take a Request instance as a parameter and execute a null value check in … Read more
your code is not triggering event by clicking, and you should pass argument result in resolve let onlyBtn = document.getElementById(“onlyButton”); let result; async function realMain() { await step().then((res) => { console.log(res); }); } async function step() { return new Promise((resolve) => { onlyBtn.addEventListener(“click”, function () { result = “nice”; resolve(result); }); }); } realMain(); <div> … Read more
There is no general problem with two threads executing system calls on the same socket. You may encounter some specific issues, though: If you call recvfrom() in both threads (one waiting for the PLC to send a request, and the other waiting for the PLC to respond to a command from the server), you don’t … Read more
I want to know if there is any way at all to use the data from a resolved promise in ‘normal’ synchronous code There isn’t a way to write completely synchronous code when handling asynchronous responses. Once any operation is asynchronous, you have to deal with the response using asynchronous techniques and cannot program with … Read more
Synchronous means that the code that initiates the synchronous requests waits and blocks until the request completes. The calling and the called code are “in sync”. Asynchronous means the code that initiates the request continues immediately and the asynchronous call will complete sometime later. The calling and the called code are “not in sync” or … Read more
You can make Main() method async as well and use WhenAll instead of WaitAll. And use just T() when assign Task to array item, there is no need to do it like that new Task(async () => await T()); static async Task Main() { var tasks = new Task<bool>[10]; for (int i = 0; i … Read more
Introduction If you are looking for a way to run multiple tasks and get the results after all of them have ended, then you have come to the right place. In this article, we will discuss how to run many tasks and get their result after all of them have ended. We will discuss the … Read more
How does async-await allow for responsiveness in an application that uses an event loop, such as Windows Forms? [closed] solved How does async-await allow for responsiveness in an application that uses an event loop, such as Windows Forms? [closed]
As of jQuery 1.5, a XMLHttpRequest (jqXHR) object is returned by $.ajax(). This is the object you assign to your var msg, and later put in the alert. Hence you get “alert as object” as you describe it. If you want to alert what is returned by the server, do: success: function (data, status) { … Read more
Return a promise from your config.js file. mongodb client supports promises directly, just do not pass the callback parameter and use then. config.js module.exports = (app) => { const mongo_client = require(‘mongodb’).MongoClient; const assert = require(‘assert’); const url=”mongodb://localhost:27017″; const db_name=”portfolio”; return mongo_client.connect(url).then(client => { assert.equal(null, err); console.log(‘Connection Successfully to Mongo’); return client.db(db_name); }); }; And … Read more
Case B is not async-await. If you have a thread, and this thread has to start a fairly lengthy process in which it has nothing to do but wait, usually because someone / something else performs the operation, then your thread could decide to do something else instead of waiting for the operation to finish. … Read more
