WCF learning tour-HTTP duplex mode (20), wcf duplexWCF learning tour-request and Reply Modes and one-way mode (19th) Iv. HTTP duplex mode 　The duplex mode is based on the two modes implemented above to achieve mutual calls between the client and the server: the two methods described above are only the methods for the client to call the server, then, the server re

The network card transmits the data, according to the direction of the data flow can divide into four kinds of basic transmission way: full duplex, Half-duplex, simplex and automatic detection four kinds of way. But simplex is now rarely used, and the following are just two common ways If at any point in the communication process, the information can only be transmitted by one Party A to the other party B

WCF duplex mode and wcf duplex modeThe message mode of WCF is divided:1. Request/reply Mode2. unidirectional mode3. duplex mode The request/reply mode is shown in the blog: WCF getting started tutorial 1 (create and deploy the first WCF Program) WCF tutorial 2 This section describes the unidirectional mode and duplex m

Based on the division of labor between the two parties and the signal transmission direction, the communication can be divided into three modes: Single-work, half-duplex and full-duplex. In computer networks, the dual mode is used. The LAN adopts the half-duplex mode, and the man and Wan adopt the full dual-year mode. 1. Ticket (simplex): the sender and receiver

Printing supplies in office is very expensive, so in order to save paper as much as possible, we tend to use a sheet of paper both front and back (double-sided printing). After all, there are few printers that support automatic duplex printing, and in most cases printers do not support double-sided printing, and this time we have to manually set up double-sided printing. The printer supports duplex printin

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

Win7 flagship as the mainstream operating system, many users will choose to install the upgrade on the basis of XP, and Win7 naturally carry the old-style audio hardware, but in Full-duplex mode to play the sound is certainly not ideal, so turn off Full-duplex audio mode is also necessary, then in Win7 64-bit How do I close this mode? In fact, we can use the Local Group Policy Editor to disable Full-

To the Duplex of an Ethernet card, we can use the ethtool -a Linux utility for Displaying or changing E Thernet card settings.1. Install EthtoolYou can install Ethtool by typing one of the following commands, depending upon your Linux distribution.Install Ethtool in Fedora, CentOS, RHEL etc.:# yum Install EthtoolInstall Ethtool in Ubuntu, Debian etc.:# sudo apt-get install Ethtool2.

The Duplex mode message exchange mode is reflected in the message exchange process. Both parties can send messages to the other party. Message exchange based on duplex MEP can be seen as a combination of message exchange in multiple basic modes (such as request-reply mode and single mode. Duplex MEP has some variants. For example, a typical subscription-publishin

Java sockets for full-duplex communicationSimplex, half-duplex, and full-duplex definitionsIf at any point in the communication process, the information can only be transmitted by a Party A to the other party B, it is called Simplex.If at any time, the information can be transmitted from a to B, but also by a B, but only in one direction of the transmission exist

In WCF, three message exchange modes are defined: 1. Request/reply; 2. One-way; 3. duplex.Request/ReplyIs the default mode, that is, synchronous call. After calling a service method, you need to wait for the Service Message to return, even if the method returns the void type.One-wayThis method will be returned immediately after the method is called. Note that one-way cannot be used in a non-void or a method that contains the out/Ref parameter, leading to an invalidoperationexception.DuplexAlso k

You can easily set up double-sided print Word documents in the Word2003 Print dialog box, but there is no setup option for duplex printing in Excle2003. Users can implement double-sided printing Excel2003 tables by editing macro commands in Excel2003. 1. Edit Excel2003 Macros Command The first time you use the macro feature in Excel2003, you need to add a Personal macro workbook (that is, Pernosal.xls), and then use the Visual Basic Editor to edit t

Let's explain what duplex mode is. Duplex: The way information can be sent in two directions simultaneously between two points. The meaning of duplex can be two-way transmission at the same time, as usual in the phone call like that. Devices such as walking on a phone are half-duplex or simple
