I want to develop a chat software in ASP

There are many freely available chat scripts on the net...just do a search in google or go to your favorite free script site. Use something out of the box or modify it.

Just because your site is in ASP doesn't mean that you're tied to ASP for your chat system. It might be nice to have ASP based chat if you want to do something like share session variables for logins or whatnot, but if you find a better system implemented in CGI or Java Servlets or PHP, there's no reason you couldn't use that side-by-side with ASP.

Good luck.

Actually, I wanted to ask the way that how can I develop chat server in ASP? Is there any component for chat sevices in ASP (like CDONTS for mail).

Here's an entire list of ASP chat servers...buy or download one and inspect the source. No one will be able to tell you "how to develop" a chat server...at least not in the space provided for these answers.

http://www.aspobjects.com/Applications/Chat/
These are complete chat applications

http://www.aspobjects.com/ASP_Components/Chat/
These are exactly what you asked for, chat components (COM objects).

http://www.hotscripts.com/ASP/Scripts_and_Components/Chat_Scripts/more3.html
Thislink has more free options than the first two links (note you usually get what you pay for).

Here's yet another list of free and commercial ASP chat products.

This list of links took me five minutes to find in Google. Try searching a little bit if none of these links have exactly what you're looking for. Again, I encourage you to investigate the source of existing freeware chat products to learn how to code your own.

Good luck.
