Hi all, I have the same question here. I am trying to build a chat application for my webpage. What i need to do have is implement private chat. So far i have done the chat application using a database and using a timer which checks every 3-5 secs to refresh the messages. My question is : I need to eliminate the use of timer and want to implement it as a condition. i.e only if the user enters a chat into the box should the other person refresh his text box and it shouldnt be run on a timer. Is it possible? Please help.
