Hey, I'm trying to make my own packet scanner and I need any possible information on how to make this or where to start. If anyone has information, source code examples, or if anyone is willing to guide me through this, I would gladly offer extra points. Thanks a bunch!

I don't believe winsock has the ability for such so you can ignore all those PSC links. You can, however, try to use the WinPCap drivers. If you'd look to research the methods yourself you can try the below link. Mainly for TDI & NDIS.

Hey its me again, I looked at the PSC links and like zzzzzooc said, winsock is incapable of doing that. BUT! I did check out the PacketVB dll, thats almost exactly what I needed. I had one problem with regsvr32 on the dll, but I think I'm going to switch to using WinPCap. Thanks to both of you!
