but another question do you always have to make a server and client app ???
I would personally use the System.Net.Sockets object.. Winsock provides the same level of functionality except it is a com object and therefore depreciated... Now to your quoted question here.. You can always insert messages to an online sql database and have the application poll the database for messages.
