PC to PC file transfer

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi all,

I need to add to my app a computer to computer file transfer. I can't
use any components so I have to do this all from code. Basically, I
need to be able to input the recipients IP address and port (they run
the same app and press "listen" on a configured port to make their app
wait for a signal from the sender) and send any file. This needs to
work with binary files as well.

I know I need to use a FileStream but I have been banging my head
against a wall on just getting started. Does anyone have any
suggestions or have perhaps done this before and would like to share
some code?

I have been googling a while but none of the results I have come up
with have helped so I thought I'd ask fresh.

Please help!
TIA
