i want to create a messaging page in asp.net, where a user can send message to another user (just 2 users per chat), I thought of using Unique identifier to keep the message between the two users, but i dont know how the Unique identifier will be generated for the two users once one of them clicks on the other user to send message, PLEASE HELP

Are you sure you are ready to create a chat eh?

dhtml: hello seun
that goes into database like this:
to->seun, from->dhtml,message->hello seun,time->now,status->unread

Since seun is obviously online, javascript/ajax checks message thread for unread messages posted to seun
seun now sees:
dhtml:hello seun
and the status is changed to read

and the messages go back and forth?

i get that, i tried that, but i have problem when i want the user to reply the message and still be displayed on the same page from the database

That is where javascript/ajax comes in. See, developing a chat system is not beans at all, you must really be an expert before you can create one that works properly. These challenges you are facing are just a tip of the ice berg, there are more difficult challenges ahead of you to create a chat system.

well, i can create a chat application, with signalr (a javascript language for asp.net), but i dont know how to save it in a database, dats why i want to use an alternative for the same thing

A chat will definitely involve database for data persistence over network. You must do proper research on how to get that done, i dont use .net so i cannot really help you much, i can only give general advices.
