Using Alvaro Mendez's implementation, calling server functions from the client is very simple. On the client side, remote scripting is used to send messages to the chat room. This.RegisterClientScriptBlock( ' timerScript',strScript) String s=room.JoinRoom(Session.ToString(), OtherUser.Value=Request.QueryString ĬhatRoom room=ChatEngine.GetRoom(Session.ToString() , ( ' onkeypress', ' return clickButton(event,'btn')') if this is a callback function return return Private void Page_Load( object sender, System.EventArgs e) In Chat.aspx, a chat room is created for the two users: Then the user is redirected to chat.aspx with the name of the other passed in the query string and saved in a hidden variable.

The two user names are used to create the ID of the chat room. After that, the user enters the nickname of the other user he wants to chat with. First, we create a simple page ( default.aspx) where the user can enter his nickname (which is saved in the session). I will build a simple app to demonstrate the usage of the Chat Engine classes. Other operations in the class include creating new rooms and deleting the empty chat rooms.

The ChatEngine class: contains a HashTable of chat rooms.

The class contains the common operations for a chat room like joining, sending message and leaving the room. The messages are stored in the ArrayList messages of Message instances. Public Message( string _user, MsgType _type) : this(_user, ' ', _type) Įach chat room can have two users only represented by the two members FirstUser and SecondUser. Public Message( string _user, string _msg, MsgType _type)
