Firewall in VC++

hi,
you need to interface with the network card, win32 api provide you access to this network card via a generic interface defined, please refer to msdn for more details, also if u r trying to access a specific feature provided by the network card then i am not sure in win32 will support it, u may have to interface it with c via the memory read/writes.
