There is a need for a new project recently, requiring users to participate in the activity in the user preemptive experience. The dynamic scroll bar on other pages can be immediately displayed, the latest activity Participation information. Previously, we could use JavaScript to use the long polling method on the front end. This time we used signalr, an open source library of Microsoft, to implement real-time communication in ASP. NET web projects. Ge

The ASP. NET SIGNALR is a class library that Microsoft implements for real-time communication. In general, SIGNALR uses JavaScript's long polling to implement client and server communication, and SIGNALR also supports websockets communication as websockets occurs in HTML5. In addition, the program developed by SIGNALR

Original: SignalR Simple exampleFirst, what is SignalR　　ASP. SignalR is a library for ASP. Developers that simplifies the process of adding real-time web Functiona Lity to applications. Real-time Web functionality is the ability to has server code push content to connected clients instantly as it becomes a Vailable, rather than has the server wait for a client to

The icon to open the Chat window is also not processed (if the user is not on the line, the icon is still lit)Now get to the point, all backstage operations are to provide data to the front end. Then the front-end as long as one thing can, receive messages, according to users on the offline change the status of the user Picture. My method is to use a third-party js.

First, the introductionIn the previous article has introduced how to use SIGNALR to achieve the function of the chat room, in this article, will implement how to use SIGNALR to achieve the function of sending pictures. Second, the realization of the idea of sending picturesI still follow the previous way to tell this article, first of all, let us clarify the realization of the idea of the function of sendi

Getting started with SignalR Hub, signalrhub Based on persistent connections, SignalR provides a high-level abstraction layer: Hub. Based on the flexibility of javascript and the dynamic characteristics of C #, Hub is a crucial development model, it eliminates the boundaries between the two independent physical environments, client and server. The most common usage mode in the Web environment allows us to t

1. Reasons for choosing SIGNALRThe SIGNALR interior gives us a lot of encapsulation. When the server or browser does not support the Websoket protocol, the use of long connection mode does not support long connections and select polling method to get messagesWebsoket: Keep A long connection to the server and the client can do duplex communication without establishing a new linkLong connection: The server maintains a long connection with the client. Th

. Net SignalR winform push broadcast, signalrwinform Recently, I am working on a project and need to use the server to actively push the data to the client. I first used my own Remoting, but later I found that I had mounted the server to the Internet, so I was monkey's brother, later, I tried WCF. Although I could push it, I pushed it several times, and I found SignalR. I checked the information about the c

Using the Canvas canvas feature of HTML5, painting on the page, and then submitting the color of each point of the canvas to the server through SIGNALR, the server also pushes the information of these canvases to other clients, enabling the ability to share the same artboardSimilarly, painting in one browser, other browsers synchronizing the content, and the page refresh or first load can also display the previous painting content (the site does not r

The underlying API for accessing SIGNALR persistent connections provides an abstraction layer that hides the underlying inherent complexity in order to maintain the exploitation of persistent connections between the client and the server, and to send data on such connections using transport.In fact, accessing the communication channel through the API is similar to using the socket at the bottom:On the server side, we are notified when the connection i

SignalR Self Host + MVC and other multi-terminal message push services (2), signalrmvc I. Overview In the previous article, we implemented the SignalR self-managed server. Today, we use the console program to call the SignalR server to push information. Because we were planning to push approval messages, therefore, our demo is intended to send messages to designa

First. Chatjs is based on the implementation of SIGNALR web-side IM, interface style imitation is "Face book", can be easily integrated into the existing products. Project official website: Http://chatjs.net/github Address: Https://github.com/andrerpena/ChatJS on the browser side, Chatjs is a series of jquery plugins, These codes are written using Typescript (an object-oriented superset of JS developed by Microsoft, which can be compiled into JS). On

First, the introductionIn the previous article I introduced how to use SIGNALR to implement picture transmission, and then for instant messaging applications, message reminders are essential. Now a lot of Web sites have new messages to remind the function. Nature for the SIGNALR series is also indispensable to the realization of this function. In this article, we will describe how to use the

HTTP protocol is a typical request/response protocol, is based on TCP/IP above an application layer protocol, the most typical feature of this Protocol is stateless and requires the client to launch the request server to response, which means that the server can not actively "push Information But many modern application requirements such as "service-side push", such as monitoring systems, pricing systems, games, collaborative documents, progress bars and other applications. Therefore, this artic

Getting started with SignalR simple example tutorial I went to work at the company on the last day of last Friday and wanted to do something when I was bored. someone asked me to make a simple version of online chat, so I decided to spend a day to get a simple tutorial on SignalR and create an online chat. 1) 2: A new Hub inheritance class ChatHub is added to the MVC project. The HubName tag is similar to a

First, Introduction In the previous article I described how to use SIGNALR to implement image transfer, and then for instant messaging applications, message reminders are essential. Many websites now have reminders for new messages. Naturally for the SIGNALR series is also the realization of this feature. In this article, you will learn how to use the Signalr+ino
