2. Long Press any group chat
A preface
The interface supports multiple languages and encounters the following problems when using ASP.net's self-contained multilanguage scenario:
When you do the functions of the management class, have to add, modify and view the page, need to support multi-language control is basically the same, but to maintain multiple, resulting in redundancy (ASP.net has shared resources, but it is global, can not be divided into modules, we can not be the module of the information into the global reso
1 in the mobile phone to open a letter, and then we click on the message above the letter of the symbol, and then find "Free sms" and then click to select Friends such as figure;
2 Now in the friend selection we will see that there is a "group" now we can in the group to implement a single selection or select the full selection after the completion of the click to determine the details as shown in the figure.
3 appear to send a text
Note: This method can only see text messages if the image is withdrawn is not able to see, because the iphone notification bar will not save the picture will only display text.
To view the methods of a message that has been recalled:
So in the micro-letter we can not see, if you want to see the following may be set
When the iphone is set up, click on the notification effect as shown below.
Enter the notification bar-to the micro-let

It should be clear that MFC's message loops (:: GetMessage,::P eekmessage), Message pumps (CWinThread::P umpmessage) and MFC messages are routed between windows in two different things. In an MFC application (the application class is based on CWinThread inheritance), you must have a message loop that reads the message
The message structure consistent with twmmouse is as follows:
Detail {left-click} twmlbuttondown {left-click} twmlbuttonup {left-click to raise} twmmbuttondblclk {middle-click} twmmbuttondown {middle-click to press} twmmbuttonup {middle-click to move} else {right-click} twmrbuttondown {right-click and press} twmrbuttonup {right-click to raise}

NET message loop of Mystery (-)http://hi.baidu.com/sakiwer/item/f17dc33274a04df2a9842866Those who have fought under the Win32 platform must remember how many sleepless nights were spent trying to figure out the concept of a "message loop". Although we no longer need it in the process of writing application code, it is still necessary to have a deep understanding of the
1. What is a window?
Msdn: In a graphical Win32-based application, a window is a rectangular area of the screen where the application Displays output and records es input from the user. therefore, one of the first tasks of a graphical Win32-based application is to create a window.The window is a rectangular area, which is appliedProgramYou can use it to display the output, or obtain the input from the user (keyboard and mouse ). In Windows, "Everything is a window ". Although not very relevant
All Windows applications are message-driven, and message processing is the core part of all Windows applications. When you click the mouse or change the window size, messages are sent to the appropriate window. Each message corresponds to a specific event. STEP/Method

Summary : This article describes the use of Windows Messaging mechanisms to communicate with each other in different languages, connect to each other, and in two languages that are currently more prevalent in Microsoft Visual C + + 6.0 and Borland delphi5.0 is an object that uses both languages to compile an application and to interact well with messages. keyword : VC + +, Delphi, message I, Introduction Developing larger programs often inv
IntroductionIn Android, we usually use Android's messaging mechanism to communicate between threads, and this mechanism passes exactly the message.Usually. We use Message.obtain () and Handler.obtainmessage () to get a message from the message pool. Avoid constructing a message directly.
So does Android cause oom because of the
Android message mechanism (Handler message transmission mechanism)
For the sake of performance optimization, android UI operations are not thread-safe, which means that if multiple threads operate on the UI component concurrently, thread security issues may occur and this problem is not solved,
From the perspective of development, Handler is the upper-layer interface of the Android
Android's message processing has three core classes: Looper,handler and message. There's actually a message queue, but MQ is encapsulated in Looper, and we don't deal directly with MQ, so I don't use it as a core class. Here are the following:Thread of the magician LooperLooper literally means "circulator", which is designed to make a normal thread into a looper
Android Instant Message Processing Mechanism and android Instant Message ProcessingHow to ensure instant messaging without consuming power when making instant messages on android. Why? The reason is that to ensure the instant messaging, there are usually two mechanisms pull or push. The pull regular polling mechanism is a waste of server resources. The push server needs to maintain persistent connections, a
An analysis of auxiliary function schemeWith regard to WX's various functional plug-ins have been very common, and now the plug-in is dependent on the xposed framework, so the personal feel that WX should be in this convenient to deal with the use of xposed framework protection, to prevent the phenomenon of plug-ins flying, This article describes a WX app that receives a message if it is an article link that automatically opens the Browse feature.

SIP Message Type and Message format
SIP is a text-based protocol that uses the UTF-8 character set.
There are two main types of SIP messages:
One is the request sent from the client to the server );
One is the response message sent from the server to the client ).
A basic SIP message includes the starting line, one or

When such an exception is thrown in the future, you must know how to handle it!2.2 Message QueueIn the single-thread model, Android designs a message queue to solve similar problems. The message queue can be used between threads to exchange information with handler and logoff components. They are described as
