Uploading a file

hi all, I'll be short. I want to upload to a site a file that I have on my pc. I've googled for some tut but all are inefficient, can anyone give me a help?

It depends on which protocol you're using. If you're using ftp try looking up on the protocol standards and impend that in your program. If you're using raw sockets (only tcp/ip) you can just send a binary stream over the socket, and make the program at the other side accept it as such.
