help about sending and receiving data thru ip adressess

[nighthawk]

hello guys,
i am working on two very simple programs right now. both programs do exactly the same thing, send and receive files from a certain specified directory.
what i dont know how to achieve, is that, i would like to put a textbox field in the program asking the ip address of the receiver. whereas on the receiver side asking the ip address of the sender. the file that i would like to send is only a .txt file. probably 50kb max. what do you guys suggest? i dont know where to start and what API to use, your help i greatly needed and appreciated. thanks in advance!

Why don't you just setup a winsock to listen on port X TCP and do whatever you want then?

WinsockVB is a good resource for winsock information.
