Re: How to deal with unplug from the LAN
Hmmm ... looks like you may have a problem with copy/paste in creating this email. in connectionStatus the first if ...then...else cluae will *always* cause a return, so the check for Airport never gets used. I suspect the original code did the Airport check first, then the Ethernet one - that would have been OK. In general, can there not be more than one ethernet interface installed - so why not check if *any* interface of the formenx ihas status active. e.g. (typed direct into email - beware typos) ... set the itemdel to : repeat for each line L in tStatus if char 1 to 2 of L = en char 3 to -1 of (item 1 of L) is a number then put lineOffset (L,tStatus) into tTarget put line ((lineOffset (Status:,tStatus,tTarget))+tTarget) of tStatus into tENstatus if (item -1 of tENstatus) = active then return true end if end repeat return 'false' -- Alex.

How to deal with unplug from the LAN
I'm working on an app that requires a remote volume to be mounted (Mac OS X 10.6) I use several basic connectivity tests like put hostAddressToName (11.11.11.11:) into the server # If I get DNS from the XServe box I know the user is at least plugged in or has his Airport connection uup and running.. # next, get a ping file which is a little file containing the word true command CheckForServerIs Mounted put url file:/volumes/XServer/Sites/public_html/ping.txt into tPingTest if tPingTest is True then set the enabled of button connected to true (small animated gif that show a live connection put true into gConnectedToLanServer # a global for later testing. else answer Sorry, the server is not mounted.. shall I mount it for you? with No or Yes # run afp apple script here to mount the remote volume. end if end CheckForServerIsMounted OK the above works fine if the user is a Tidy Boy and is careful to dismount the volume, but if he just up and pulls the ethernet cable out with the remote volume mounted and runs off to the dentist with his lap top... if he has my app open and tries anything, it goes into a 3 minute wait...( this is actually a long standing nuisance with Apple's API to the network framework... and can happen with pretty much any other app and not just RunRev) *finally* after 3 minutes, the system seems to realize he's cut off, gives up, and gives the CPU back to RunRev...my dialog pop's up to offer the user the option to mount. But because he's unplugged, his is informed he is off line and he's gracefully left to work off line... So, this all works well, but the part where I am unable to test for if the user just pulled out his ethernet cable with the volume still mounted, without this long hang up... Any ideas?
