In a service-oriented distributed environment, a standard platform-independent communication protocol is used to enable each service to interact with each other through a SOAP message. This process of interaction is actually the process of exchanging information. WCF supports different forms of information interchange, which we call the information Exchange Mode (Message Exchange pattern (MEP), below), and Common MEP includes: request/reply, one-way mode and

Using pollingduplexhttpbinding to implement duplex communication (pushing messages from the WCF server to the client) is a relatively "old-style" approach. in versions earlier than silverlight4, Silverlight does not support net. TCP communication, so it can only be achieved by packaging HTTP Communication. However, after all, no one can penetrate the firewall through HTTP, so pollingduplexhttpbinding may be used to implement

In WCF, HTTP and Tcp Protocols are often used for duplex communication. The corresponding protocols are WsDualHttpBinding and NetTcpBinding.HTTP is based on the application layer protocol, while Tcp is based on the transport layer protocol. Tcp uses three handshakes to establish a reliable connection between the client and the server. Both the client initiating the request and the server of the callback client can use one connection. When HTTP is used

Synchronous and asynchronous:BecauseSynchronize: Submit request, wait for server processing, and then returnAsynchronous: Requests are processed through event triggering server processing (which is still something the browser can do)AlsoSynchronization refers to: After the sender sends the data, wait for the receiver to send back the response , only send the next packet communication mode.Asynchronous means that after the sender sends out the data, the receiver sends back the response , and then

1. What is WebSocket WebSocket protocol is HTML5 a new protocol. It implements the browser and server Full-duplex communication (Full-duplex). The first handshake needs to be done with an HTTP request. 1. Traditional way of web communication 1. Working mode: Client Request-service-side response 2. Applicable scenarios: Information changes are not particularly frequent occasions, such as Web page refresh 3.

The contract requires duplex, but the binding "Wshttpbinding" does not support it or is not configured correctly to support itI have encountered the following two situations.OneTwo, app. ConfigAdd between Copyright NOTICE: This article for Bo Master original article, without Bo Master permission not reproduced.The contract requires duplex, but the binding "Wshttpbinding" does not support it or is not config

This article mainly studies the use of HTML5WebSockets, which is the most powerful communication function in html5. it defines a full-duplex communication channel and can communicate with only one Socket on the Web, this reduces unnecessary network traffic and network latency. HTML5WebSockets can reduce the data size from several thousand bytes to two bytes, and reduce the latency from ms to 50 ms. It is perfect for the current implementation of real-

I have always thought that the WCF duplex communication method in Sl is a little tricky. If it is implemented in http mode, the efficiency is too low. If it is implemented in TCP mode in sl4, it is the same as socket, so I have not studied it, however, this is easy to implement when the performance requirement is not high (for example, the weather forecast/stock information is updated every five minutes on the webpage. Compared with traditional WC

. Hop layer: A hop layer residential building occupies two floors, with Internal stairs connected to the upper and lower layers. Generally, the living, kitchen, dining room, and bathroom are arranged on the first floor. It is best to have a bedroom, bedroom, study, and bathroom are arranged on the second floor. Duplex: the duplex residence is a level in concept, but the height of the ordinary residence is

. Second, implement the icallback interface of the server. A) add service reference B) implement the icallback interface. Note that the show method in this class is called without any code on the client. Using system; namespace mywcf. wcfsimpleduplexconsoletest. ctest {/// 　　 C) Overall client: 13. Then the code in the program is recommended for One-Step debugging to see the code running process: Using system; using system. servicemodel; namespace mywcf. wcfsimpleduplexconsoletest. ctest {c

An embedded system usually needs to carry out Full-duplex communication with its main control system, for example, a pipelined control system needs to continuously accept the query and control information sent from the master control system, and send the execution result or query result back to the master control system. This paper introduces a simple Java class library which realizes Full-duplex communicat

to set up duplex printing, follow these steps: Step one: Go to the Control Panel--> "View Devices and printers" Step Two: Right click on the current valid printer icon, in the right-click menu, select "Printer Properties", as shown in the picture, do not point to the wrong OH Step three: In the pop-up Properties dialog box, you can see the rightmost tab, "Device Settings," Select it, see "Installable Options" by default Sele

In a Word 2010 document, the user can set the implementation to print the current Word document on the front of the paper when using a printer that supports duplex printing, as described in the following procedure: Step 1th, open the Word 2010 document window, click the file → options command, and so on, as shown in Figure 2011121903. Figure 2011121903 Click the Options command Step 2nd, open the Word Options dialog box and switch to the Advanced

First look at the running effect: send a message "like" in the Web page, use WCF's duplex service to push messages to the WinForm program, WinForm end receive messages, Create two projects, a WebForm project and a WinForm project, and build the files you need under the project Sendmessage.aspx is a Web page that sends messages ISendMessageService.cs and sendmessageservice.svc are used to implement WCF dup
