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

The issue is definitely related to the order of the include files. I haven't developed an MFC-based app in Visual Studio 6 in a very long time (I don't even have it installed on my machine any more, I use VS2005), so I tried a bit with VS2005.
In my case, I had to include pcap.h after afxwin.h. That did the trick.
Let me know if this solves your issue.
Have a nice day

The answer I need is: How do I use WinPcap with version 6 Visual C++? The answer you have given is a generic answer that does not address the fact that I am working using a standard Visual C++ project. When you work in this VERY STANDARD AND WELL KNOWN project framework, you do not have easy control of what gets included where, when and in what order.
I inserted #include "pcap.h" in the project's StdAfx.h. See bottom of this post. Now I receive a different error that I don't understand. The error points to a line in pcap-stdinc.h that seems OK to me. The error leads me to believe that something previous to the tagged line is wrong. I don't understand the problem here.
Please help me.

Tom,
you need to make sure that pcap.h is included before winsock.h

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:
