I know there's been a recent update by Haack but I don't know how to use the new methods. Also, how can I provide a cancellation token so that the operation can be canceled (say, if a person is sick of waiting and presses the Cancel button in the app's UI). 回答1: Well, the update Haack is referring to has been made by me :) So let me show you how to use it, as it is actually very simple. Previously you had methods like

For example, the storage protocol library is also written with boost::asio , but without coroutines. The problem is how to convert yield_context into a normal callback (a boost::function object or a classical functor). This is what we have in the storage library API: void async_request_data(uint64_t item_id, boost::function< void(Request_result *) > callback); As we know from examples, the asio yield context can be used like this

And the test just fails on that line. What am I doing wrong? 回答1: Your method doesn't have any callbacks so there is no reason to use .CallBack() . You can simply return a Task with the desired values using .Returns() and Task

This looks to me that both are same model. Kindly suggest. 回答1: Both models are very similar. There are two primary differences, one of which is going away soon (for some definition of "soon"). One difference is that Node.js is asynchronously single-threaded, while ASP.NET is asynchronously multi-threaded. This means the Node.js code can make some simplifying

I'm new to node and asynchronous coding, so I apologize if this is stupidly easy. I want to run a function that calls the callServer() function with specific parameters, wait until it finishes getting the data, and return the data as a variable. Here is my code: 'use strict' const net = require('net') var formattedJson = funcRequestToJson("Server.GetStatus", false) doThings() async function doThings() { var info = await

So, as recommended, I'm using async/await to make sure the UI thread doesn't get blocked: private async void Button_Click_1(object sender, RoutedEventArgs e) { await GetResults(); } private async Task GetResults() { // Do lot of complex stuff that takes a long time // (e.g. contact some web services) ... } Occasionally, the stuff happening within GetResults would require additional user input before it can continue. For simplicity, let's say the user just has

Here's an example class Program { static void DoIt ( string entry ) { Console . WriteLine ( "Message: " + entry ); } static async void DoIt2 ( string entry ) { await Task . Yield (); Console . WriteLine ( "Message2: " + entry ); } static void Main ( string [] args ) { // old way Action async = DoIt ; async . BeginInvoke ( "Test" , ar => { async . EndInvoke ( ar ); ar .

This example on MSDN, although overcomplicated with synchronisation mechanisms such as ManualResetEvents, illustrates the concepts: you use a BeginXXX() and EndXXX() method pair for the connection and stream operations. This has the advantage of letting the thread pool assign threads as needed (e.g. when data is received) rather than having a dedicated thread per connection, which doesn't scale. Someone recently mentioned that

My method looks like this, - (void)doCalculationsAndUpdateUIs { // DATA PROCESSING 1 // UI UPDATE 1 // DATA PROCESSING 2 // UI UPDATE 2 // DATA PROCESSING 3 // UI UPDATE 3 } As it is time consuming I wanted to do the data processing on the background thread, using, dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, NULL), ^{ But as both data processing and UI updates are in
