I would have thought not, but make sure the public variable is not being corrupted by another received packet meanwhile, it should be kept for the FIFO queue. I use SendTo in my IP Logger component, which will send and receive UDP and TCP packets. I've just run the demo on two PCs, each listening and sending on port 5555, sending packets to each other. Not exactly the same as your application, but almost. http://www.magsys.co.uk/download/software/magiplog11.zip Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
