This sounds like a homework assignment. Try something like this ... Create a message table with timestamp, usernameTo, UserNameFrom, Status (Read/Unread), MessageText. When someone sends a message, you insert a record into this table. You would have to create a client application which checks to see if a message is pending for your current user and retrieve it from the db and display it in a chat window. The other guys who replied are correct, you need to investigate TCP/IP chatting otherwise your client application will be constantly polling the db for new messages. However, i think this basic design will get you through your homework assignment.

not necessary across the internet , its between users , that users use my application in local lan Example an accounting program in a company any user can send message to other user use the application i hop the issue is clear now thanks
Well, you did say in your original post "I hope I was clear". Nope. If you mention chat, everyone immediately thinks two remote machines over an IP network.

That makes no sense. If it's not between machines and is instead between two users, couldn't they just turn their heads and talk to each other?? Of course it's between two machines!

Dave KreskowiakOf course it's between two machines when i mean two user that means two users use same accounting application, and that users one in department of company and other from another department "again same application on two machines and single DB 'SQL Server" thanks anyway Dave

In a world where email is ubiquitous and, almost so, a corporate instant messaging system, is there really a need for this?? I think your application is trying to solve to entirely seperate and unrelated problems that do not need to be in a single application.
