Stuck with packets/sockets

Hi everyone, I'm currently attempting to create a 'bot' that will connect to a Flash game and send and receive packets. However, I'm a bit stuck as to how I should go about doing this...

I've searched about dll injection, sockets etc., but I haven't found anything that really gives me an idea of what I need to do, hence why I decided to join this forum and ask others.

If I could get some sort of send/recv packets to a server thing going, that'd be a real push in the right direction!

I'd be happy if someone could help/tell me what I need to know to complete this. Thanks :)
