Yunqian open source IM is a lightweight IM developed using ASP.NET, Ajax and Comet technologies. The main functional features are as follows:
1. The server of Yunqian's open source IM is actually an ASP.NET website, so there is no need to use a separate server. It only needs a Web space that supports .NET2.0 to deploy IM to the Internet.
2. You only need to copy two folders and embed a line of code in the page to integrate IM into your own website or the company's internal OA system.
3. It can run in client mode and Web mode at the same time. Both have exactly the same operation interface.
4. Provides visual development tools to facilitate you to quickly develop the interfaces and controls required for IM. These interfaces and controls can run on the client and WEB desktop at the same time, without writing two sets of codes.
5. Message records (including pictures and files in messages) are stored on the server. As long as you have access to the Internet, you can browse your message records anytime and anywhere.
