How to Create a duplex windows Communication Foundation (WCF) service that can communicate with the Silverlight client. The Duplex service will be retained to the callback channel of the Silverlight client, which allows the service to call the client. Duplex services have many applicationsProgramFor example, this includes a chat service program for instant messag

Http://blog.csdn.net/fangxinggood/archive/2011/01/15/6142861.aspx 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

C ++ uses WinSock to implement full-duplex voice communicationHttp://www.4oa.com/Article/html/6/33/486/2005/17465.htmlHttp://www.4oa.com/Article/html/6/33/486/2005/17465_2.html I. IntroductionWindows 95, as a microcomputer operating system, has fully integrated the network and communication functions. It can not only establish a "peer-to-peer network" in a Windows 95-only environment, but also support multiple protocols, such as TCP/IP, IPX/SPX, and n

reason is very simple. The construction time of the data center is earlier, and the upper-layer network equipment has full duplex and half duplex problems, which must be specified by force. 2. After the data center sets the network connection to full duplex, the network immediately returns to normal, and the speed between data center 1 and Data Center 3 reaches

A long time ago to modify the Linux system network card operating mode command is Mii-tools, and later with the development of computer server hardware, has already entered the era of 1000Mbps popularization, now the large server is basically million trillion working mode.Mii-tools does not correctly identify more than 100M network cards;The clock rate is 25MHz because MII transmits the data bidirectional transmission in 4-bit half-byte mode. The operating rate is up to 100mb/s.The Ethtool tool

Can only make full use of good resources, will be able to achieve double-sided printing function. Here are four ways to do this: 　　1, the use of Word2007 to achieve rapid and double-sided document printing Word is currently the most common Office software, in Word2007 to achieve double-sided printing is very simple. Click the Office Button, click Select Print in the Drop-down menu, click the Manual Duplex option in the Print dialog box, and then cli

Before setting up, 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

ADF is a set of enterprise development solutions provided by oracle. For a recent performance test, you need to obtain the number of SQL queries on the current page and the amount of time it takes. The first thing that comes to mind is that the common log4jdbc result ADF does not support encapsulated drivers. Later, I tried to intercept it on the ipve DB layer. It was complicated to set the sesson attribut
