I think you can use this:
code:
function OnEvent_ChatWndSendMessage(ChatWnd, Message){
var Contacts = ChatWnd.Contacts;
var e = new Enumerator(Contacts);
for(; !e.atEnd(); e.moveNext()) {
var Contact = e.item();
Debug.Trace(" " + Contact.Email);
Debug.Trace(" " + Contact.Name);
}
}
It should get all participants in a conversation.
