Check the internet connection state

[Athropos]

Hello,

I would like to be able to detect if the computer is connected to Internet. I've tried InternetGetConnectedState() from wininet, but I always get TRUE, nethertheless I'm connected or not. :confused:

I would like my application to check pop3 accounts, but if the computer is not connected, there is a hang (big timeout when trying to connect).

Thanks.

check this source:

its i Win32Asm, but there isn't much diff, actually they are the same, just diff syntax!
have fun translating

Thanks, dont worry I've got no pb with asm and it's the same API.

to translate......(even though i'm sure you can do it)

WSADATA wsadata;
WSAStartup(0x101, &wsadata);
if(gethostbyname("www.microsoft.com") != NULL)
We_are_online();
else
Offline();
WSACleanup();


this is one method but also you might want to try using
gethostname();
and then gethostbyname(); with information returned from the first one. then you can enumerate the IP list returned and check against common local ips *127.0.0.1 or home network ones*

BOOL InetIsOffline(
DWORD dwFlags,
);

or

DWORD RasEnumConnections(
LPRASCONN lprasconn, // buffer to receive connections data
LPDWORD lpcb, // size in bytes of buffer
LPDWORD lpcConnections // number of connections written to buffer
);
