How to detect when we connect to internet

[abrar]

I want notification to my s/w when connected to internet

[Ghazi /Dundas]

Use

BOOL InternetCheckConnection(
IN LPCSTR lpszUrl,
IN DWORD dwFlags,
IN DWORD dwReserved
);
with lpszUrl as NULL

I've been using this successfully


DWORD lpdwFlags ;//= INTERNET_CONNECTION_MODEM|INTERNET_CONNECTION_LAN|INTERNET_CONNECTION_PROXY ;
if( InternetGetConnectedState(&lpdwFlags ,0) == TRUE){ ....}





maybe - InternetCheckConnection works as well, but I thought it checked to see if you could connect.. Oh well

Hi,
I had once the same problem. Here the code to get the connections open to the net.
If the enumeration returns NOT 0, there is no connection. Else you can even see which ones are open.


RASCONN ras[20];
DWORD dSize,dNumber,dCount;

ras[0].dwSize = sizeof(RASCONN);
dSize = sizeof( ras ); // Get active RAS - Connection

if( RasEnumConnections( ras, &dSize, &dNumber ) == 0 )
{
for( dCount = 0; dCount < dNumber; dCount++ )
{
do something
}
}




Have fun
