Hello Experts:

What I actually need is some help with Winsock connection management.  I am working on an application that has some functionality similiar to ICQ or AIM.

I have a client application and server application and can successfully connect multiple clients to the application, but the problem i am having is managing who is connected to each instance of the Winsock control.

Does anyone have any suggestions on how to manage this, so when user A on Winsock(1) wants to send a message to user C on Winsock(3), this can be accomplished successfully.

How about create a two dimension array.
nick name and which winsock
user A , 1
user B , 2
user C , 3

when user send message, winsock will send "*user C*" in front of message.  e.g.  "*user C*Hi, how are you?"
then you will have a function to retrieve the 'user C' from message.

after that, use it to check the nick name in array and send to correct person.

I was thinking along those lines but won't that be tremendous overhead if say 100 people connect to the server?  

Also, what if user B drops out --  that would require some complex array management.

I think it would be slick to have it store the connection that the users are connected to, then that could be passed as a parameter..so

User(1)=UserA
User(2)=UserB

and the array element would indicate which Sock(x) that user is connected to...but seems like complex array management.

If don't want to use array, how about using Microsoft Access to store those information?  A table with at least two fields.  one for nick name, another one for which winsock.(another field for status if you want ^_^)


when a connection fail/close, just delete that record for that instance of winsock.

when look for an user name/nick name, just search a record in table..

interesting thought.  Im actually using an Access database already to keep track of member names, so I'll give this a try.
