Hey there,

I am trying to design a Cocoa program that, when a checkmark is checked, an action will happen (like pinging a server) I'd like it to be user friendly, and avoid the terminal. I'd also like it to work even when the Cocoa app has quit.

My solution is, right now, to just update an entry in the crontab file each time the checkbox is checked/unchecked. The cron entry would just be a call to some perl script I wrote.

I don't know, however, if this is the most elegant way to do what I want to do. Is there some OS X way to make stuff happen periodically without directly editing the crontab -l script? I think Sherlock does it with its periodic indexing, but it has no cron entry. Does that mean Sherlock is Magic?

Thanks!

No, Sherlock just runs an extra process in the background all the time. This might be the best thing for you to do. See the "Foundation Tool" project template, and then use some form of IPC (Distributed Objects, Mach Messages, pipes, sockets, whatever) to communicate with it from your GUI.
