[Winpcap-users] struct bpf_hdr mismatch

[Gianluca Varenni]

Gisle,

I just tried your code snippet from the VS2008EE IDE, and it didn't compile 
as it was. I had to change the order of the #include directives (not 
surprising, it's always been like that. You need to include packet32.h 
before windows.h).

After that, the result was "sizes ok". I used the developer's pack for 
winpcap 4.1 beta4.

Can you please send me a zip file of the VS2008EE solution that you used for 
the test?

Have a nice day
GV
