I need to put content from web presentation on CD... interface contains
external links (absolute urls..) is there a way to detect if user is
connected to the internet (so if they're not I can pop an alert saying
'sorry, you're not connected...' etc..) this is for CD's that will be
widely distributed/sold.. so needs to be 'bulletproof'... (that it
doesn't by error detect user is not connected if they are and
vice-versa, etc..)
thank you.. Frances

Yes, but not with javascript appropriate to this group.
It would be OS-dependent code. For windows, you could use the windows API to
check that, but that would have to be done in C or VB (J#.net, etc). JScript
in .net is the closest you'll be getting to javascript.

I don't know of any other *reliable* way to check other that that.

You can't, at least on the "bulletproof" level.

IE gives you navigator.onLine property (true/false), but it shows only if
user is in the "global offline mode" (thus, there was an autoconnect attempt
and s/he pressed cancel on it).

Re-think your model. How about a welcome screen (flash/video/audio limited
by your good taste only) with options: "Connect now", "I'm already
connected", "Stay offline".
Set a glob var upon selection and dance from that point forward.
