Firewall warning !!

[mkbs]

Hi to all,
I have a strange problem.
Sometimes when I run my program (built with VC++ 2003) the firewall
wake up and say...this program try to connect to internet to address 239.255........
BUT into my software I don't have code to connect to internet neither that address.
What's happen ? Who try to connect to internet ? Some MS VC++ dll ?

many tanks

It may very well be if you're using sockets, for instance, or some APIs from the Ws2_32.dll, such as gethostbyname(), etc.

First of all, are you sure that the warning is about your program?

And secondly, if you built it as MFC project, what classes did you use?

If the IP ends in 255, then it's probably broadcasting, which is normal.
Why it's broadcasting probably has to do something with the .libs you linked to.

You can use the dependency walker to see what DLLs are linked to your program.
