[Winpcap-users] Using WinPcap with Visual C++ version 6.

[Tom Chapman]

I have an existing MFC project that uses Visual C++ Version 6. I want to add
WinPcap to this project. In one of my .cpp files, I added #include "pcap.h".
When this file is compiled I receive a bunch of compiler errors. Apparently
WinPcap includes winsock2.h and this conflicts with winsock.h that the
compiler is already using. I can't find how to make this work. In older
posts on the web, I have found various "ideas" people have posted as
possible solutions. Many of these posts are not my exact situation. None of
these have worked for me.

*How can I get the compiler to work with WinPcap?*

FYI: I have installed the platform SDK Aug 2004 edition. Do I need to
register this somehow within Visual C++? How? Where in the menus?


Thank you for helping me.


Below are the first few errors that I receive:
