C + + Concurrent programming asynchronous task asynchronous task Std::async(1) Std::async returns a Std::future object that holds the final computed result. When this value is required, only the Get () member function of the calling object is required. And the thread will not block until the expected state is ready; After that, the result of the calculation is re

the server for mass data, such as sending messages to all online clients, in order to better explain the implementation mechanism of asynchronous network communication, develop a multi-client LAN Chat program to demonstrate asynchronous operations.Features are as follows: LAN chat room support multiplayer online, the upper limit depends on the computer performance of the server.

The example in this article tells you that C # uses system methods to send asynchronous messages. Share to everyone for your reference, specific as follows: Project background: A recent refactoring of a project several years ago found that the Send mail feature takes a certain amount of time to process, and because the send is synchronized, it can not perform subsequent actions when sending the message T

This article is only for the purpose of summing up, referring to a lot of predecessors articles, plus a little bit of their own understandingC # Synchronous and asynchronous threads rely on delegates to accomplish the main need to use the Invoke method of the delegate, BeginInvoke and EndInvoke methodsThe so-called synchronization line is to block the current thread to complete the call method, and then continue to call the current thread after the op

Net Framework provides two design modes for asynchronous operations: asynchronous operations using iasyncresult objects and asynchronous operations using events. Overview The iasyncresult Asynchronous Design Mode implements asynchronous calling of the original synchronous

Using the TcpListener and TcpClient classes to listen to the client connection, accept, send data in the synchronous mode, until the operation is not completed, has been in a blocking state, which is not receiving, sending the amount of data is small, or the operation is relatively short case is more convenient. However, it is best to use asynchronous operations for tasks that take a long time to complete, such as transferring large files.The biggest

0. Based on the previous C # socket (synchronous) communication, after several great God comments, it was found that there are quite a few places, so write an improved version of C #-based asynchronous socket communication. Further deepen the use and understanding of the socket. The client and server are all using the WPF interface, which realizes the heartbeat,

C++11 provides a rich range of time and thread manipulation functions, such as Std::this_thread::sleep, Std::chrono::seconds, and so on. These can be used to implement a timer conveniently. Timers require asynchronous execution of an operation at a fixed time, such as Boost::asio in the Boost library::d Eadline_timer, and timers in MFC. Here, using C++11 's threa

foreground thread, the thread will not be terminated until all data is sent. Background threads should be used only when it is confirmed that the thread is terminated at will without adverse effects. If the thread is executing sensitive or transaction operations that must be completed, or you need to control the way to close the thread to release important resources, use the foreground thread. For example, there is an example in C # advanced programm

In the previous blog C # async await, I demonstrated how to use async and await to implement asynchronous programming. This blog discusses how async and await work. Suppose you have a asp.net interface, you need to request a database after you receive the parameters, and then you return the results, and the database operation takes 1 seconds.When there are 100 requests at a time point, these requests are qu

A new asynchronous operations library was added to the. NET Framework 4.5, but it is not available in the. NET Framework 4.0. Is there a choice, in the end, to upgrade the entire solution or not to use it?If your software is not yet published, it is recommended to use the. NET Framework 4.5 directly, but if you have already published and do not want the user to re-upgrade the framework to the. NET Framework 4.5, there is a way to use the library : Mi
