Hey, I'm kinda new to C++ and know that I wont be able to make a packet sniffer/filter/whatever yet (unless its easier then I think), but for future reference, how would you make a program that captures packets that a certain program RECEIVES (not send) and make it so whenever it receives a certain packet it will filter it to a different one? Can you make it so it looks for a certain part of a packet and edits only that part? For example, if you receive a packet with the hex "FF 00 03 FE 23 2A" and only want to edit the "FE 23" part to "A2 34", how would you make a C++ program where all you have to do is click a button and the program will edit that packet for you whenever it receives it?
Thanks.
