I am to design a chat window like Facebook chat style. If any user registered of my site happens to be on line he should be be made aware that I am online.

Further if he click on my profile a chat window should appear and vice versa.

If you have any suggestion please help me.

Thanks in advance.

I am using ASP.Net 2008 with C#

Spelling, punctuation, capitalization, readability.

Try reading around Socket programming in C#. Make a base before putting up questions.

I take it Google is not working where you are?

A simple Google search "One to One Chat Window c# asp.net"[^] found this: Simple chat application for ASP.NET[^]

Hi,

I was solving a similar problem some months back. Why not use a commercial solution that is available like mango chat? I spent 2 months trying to optimize my own code for bandwidth and threading issues and then just ended up purchasing mangochat since its only $99 and it already has everything taken care of.

Also if you do decide to stay with your own solution make sure to use Comet rather than simple AJAX call. That was a mistake i was making. Simple AJAX calls will take too much bandwidth as each client of the chat will be sending constant calls to the server.
