APM and EAP are two different asynchronous programming modes prior to async/await.
If APM does not block the main thread, then the completion notification (callback) will be executed in another thread, causing some problems with updating the UI.
The notification events for EAP are performed in the main thread, and there is no UI interaction problem.
Finally, we learned about the interaction between
the remoting architecture. This is obviously very cost-performance, so it's best not to use itThread Context SwitchThe Context.post method sends callbacks to the GUI thread queue, allows the thread pool threads to return immediately, and send callbacks to the GUI thread queue, but then blocks thread pool threads, but then blocks the thread pool thread, knowing that the GUI thread is completing the call to the callback method. Note that these context calls the BeginInvoke (Post) or Invoke method
This May, IDC, an almost "explosive news" of the smartphone shipments rankings, so that Oppo "forced" to go to the front of the media flash, in this ranking, "Oppo squeezed out of millet", in domestic mobile phones in the second only after Huawei.This is not only a simple ranking beyond, Xiaomi is the "Internet Model" Pathfinder, OPPO, Vivo is a typical representative of the bottom channel, the ranking changes behind, is actually two channels of the market game, this time some people think it is

I. Chinese semiconductor device model naming method
The model of a semiconductor device consists of five parts (the models of the Field Effect Device, special semiconductor device, composite tube, pin tube, and laser device are only part 3, 4, and 5. The five parts have the following meanings:
Part 1: digital representation of the Number of valid electrodes for a semiconductor device. 2-diode, 3-Transistor
Part 2: Material and polarity of the semiconductor device are represented by Chinese pinyi
so that they could take care of each other. So I decided to move out with Ge.
GE and I moved to the basement of a high-end building called Wanguo City in Dongzhimen, which is very close to my work place. This is my only basement experience. The basement we live in is below three floors on the ground. Although it is still well decorated, it will feel quite depressing when we stay in the room for a long time
I. Event-Based Asynchronous EBA)
EAP provides a simple way to use multi-threaded programming, and provides multi-threaded capabilities without explicitly opening or managing threads. At the same time, a model cancellation function is provided to securely update the properties of WPF and WindowsFormsControl.
EAP is just a model. These features must be implemented using actual code. Among the. NET Framework,

In the past, the Administrator's so-called vista wireless route setting device could not penetrate EAP packets. As long as not particularly old APS can transmit

Based on the two different application modes, WPA authentication also has two different methods. For applications of large enterprises, "802.1x + EAP" is often
The D-Link router wireless wizard is specially added to the D-Link router for users who do not know much about router settings but want to set up wireless networks.1. Before setting, we must first understand the wireless encryption type. WPA is a Wi-Fi standard designed to improve WEP Security. Compared with WEP, WPA has two major improvements. Www.2cto.com (1) improves data encryption through the temporary Key Integrity Protocol (TKIP). TKIP uses hash operations to disrupt the key, and adds Int

For 802.11, the field is evaluated to 1.3.2 Functional DivisionsSince Capwap is protocol-independent, when binding 802.11, it is necessary to divide the functio

ProSafe™The smart wireless switch (WFS709TP) is a wireless controller that enables SMEs to deploy an enterprise-class centralized Wireless LAN architecture to control and manage multiple wireless access points distributed in different locations in the workplace. The smart wireless switch provides end users with robust functions, including the ability to seamlessly roam across multiple access points, centralized security an

As a subset of the 802.11i standard, the core of WPA is ieee802.1x and TKIP (Temporal Key Integrity Protocol ).WPA takes into account different users and different application security needs. For example, enterprise users require high security protection (enterprise level). Otherwise, very important c
