How can I delete one data from ListBox?

I use this action script in client
users_so = SharedObject.getRemote("users_so", client_nc.uri, true);

I know the index is true or false meaning.
(1)true specifies that the shared object is persistent only on the server.
(2)false specifies that the shared object is not persistent on the client or server

If I use the index is true and show all data in ListBox,how can I delete one data from ListBox. I have to write some server action script, I'm not sure.

Any advices must good in my application!

If you are building just a user list, you can do it by simply defining your application.onDisconnect, like so:

application.onDisconnect = function(Client) {
this.users_so.setProperty(Client, null);
};

That should do it!
