How to retrive message list from p2p

[Saiyed Alam]

Hello friends I have a messaging system that uses p2p. Each peer has a incoming message list and a outgoing message list. What I need to do is whenever a new peer will join the mesh he will get the all the incoming messages from other peers and add those into it's own incoming message list. Now I know when I get the other peer info from I can ask them to give their own list to me. But I'm not finding the way how..? Any suggestion on this or help would be highly appreciated. I'm giving my code below. Thanking in Advance Johnny
