Hi all, I can't seem to find any declarations of the IP/UDP/TCP header structures in the include files of WpdPack 4.0.2, unlike in Linux where they are defined in <netinet/tcp.h>, <netinet/udp.h> and <netinet/ip.h>. I'm trying to use these headers in Visual Studio .NET 2003. Do I have to write my own? Thank you. Regards, Rayne
