I advise against using ping. I have my routers set so that ping is not returned. I send all ports to the local IP: 192.168.33.254 which does not exist. This is recommended by grc.com. The only open port is 80 (or whatever port you need) on a server.
I think the best idea is to download a web site page that you think will always be present like yahoo.com and examine it to make sure it is a real site and not 404 or some other error. ----- Original Message ----- From: "Andy Davies" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, June 29, 2006 1:04 AM Subject: Re: How To Know If an Internet Connection is Active Declare Integer InternetCheckConnection in Wininet.dll String Url, Long Flags, Long Reserved lnResult = InternetCheckConnection("http://leafe.com/",1,0) ?IIF(lnResult = 0,'NOT connected', 'Connected') && NOT connected * Doesn't work through [our] firewall * neither does: !ping leafe.com * wonder if it uses ping under the hood?
