I know there's lot of examples .... I've also studied some of them ... but most of them are working like this, that page at client side sends query to server for updates and then server response back with updated / new msgs. But i want that server automically sends new messages to other client/users when recieve new message in chat history database . . So for that i want to know two things .. 1- its mechanism 2- how to identify users, means i have database of users ... in which i use there ID as PrimaryKey ... and let suppose i have to send update to user with ID A, B, & C so how i now there destination ... because there are many users using this chating page/site. So plz help me.....

Now that's like good question. (Keep it up) The answer is: For the scenario you are looking for, you need to implement Observer Pattern[^] so that whenever chat history database updated you can send updates to respected user. Find following links useful... Implementing Observer Pattern in ASP.NET[^] Applying Observer Pattern in .NET Remoting[^] I have also found some articles with source code for developing chat application using ASP.NET however I am not sure whether they are using "Observer Pattern" or not. Simple Chat Application in ASP.NET[^] http://www.junnark.com/Articles/Build-a-Web-Chat-Application-Using-ASP-Net-LINQ-and-AJAX-CS.aspx[^] http://aspalliance.com/1217[^] Now, you can derive resolution of your problem from above links.
