[GD-Windows] How to detect that an internet connection is alive ?

[Fabien <ge...@fr...>]

Hello,

I am actually trying to find a simple but reliable solution
to detect if an internet connection is alive on Win32 OSes
beginning with Win95 ?

Thanks!

download a small/tiny file from a specific website that you know is there

if it works, you have an internet connection ;}

Or getting even simpler, (but maybe inappropriate): from the command line:

ping -n 1 w3.org | find "Received" /C

returns 0 or 1

Thanks a lot for these quick answer ....
But what i am really searching is for an
appropriate C/C++ solution for that ...
I might f course execute the ping but in the
particular case of my application it is not
possible ...

Btw the solution need not to not connect 
to the internet and not open the dialup 
dialogbox ... It must stay completely passive, 
just a "simple" Yes/No answer ...

Thanks,

This is what I found in our codebase:

BOOL IsThereAnInternetConnection()
{
	//may not work if you are on a LAN but you're connected through a modem
	DWORD dwFlags;
	BOOL bResult = InternetGetConnectedState(&dwFlags, 0);
	return !!bResult;
}
