Re: What is the best way to trigger an action at a certain time?
Gentlemen, The trigger will be 'pulled' once or twice a day only -- so these external to LC options are also viable. Hadn't entered my head at all! Will be playing around with all these ideas and learn something! Basically use Macs, but have couple unused Windows laptops -- sounds like Task Scheduler and .bat files might be easier to deal with.

Re: What is the best way to trigger an action at a certain time?
I think I may not have been very clear. This isn't LiveCode doing anything special; just a standalone LiveCode app that either does something immediately on launch (and then quits), or inspects the command line parameters to decide what to do (and then quits). I usually create a .bat file (on Windows) or .sh file (on Mac/Linux) to run the LC app with the appropriate parameters. On Windows you run the "Task Scheduler" and create a task to run the .bat file, with whatever schedules you like. On Mac/Linux you edit the 'crontab' file adding one or more lines with the interesting syntax to execute the .sh file. Your app can read the command line parameters (on Mac/Linux or Windows) by inspecting the special global variables $0, $1 etc. The only gotcha is that on Mac, you think your app is at e.g. /Users/yourname/Myapp - but actually on Mac what appears to be an application "Myapp" is a bundle (i.e. a folder with a special flag so the Finder pretends it's not), and the path to the executable app is e.g. /Users/yourname/Myapp.app/Contents/MacOS/Myapp On Linux and Windows, it's where you think it is!

Re: What is the best way to trigger an action at a certain time?
Slight improvement: local lInterval constant cInterval = 300 on openStack put cInterval into lInterval checkTime end openStack on checkTime -- your code send checkTime to me in lInterval seconds end checkTime setProp interval, pInterval if pInterval is empty then ask "Enter a time interval in seconds:" as sheet if the result is not "Cancel" and it is an integer and it >0 then \ put it into lInterval else put pInterval into lInterval end if end interval Bob S > On Jul 11, 2022, at 04:43 , Tore Nilsen via use-livecode > wrote: > > For this I would use a recursive approach with «send in time» something like > this: > > on openStack >checkTime > end openStack > > on checkTime > ## Do your routines of checking time, performing the required action etc. > send checkTime to me in 300 seconds. ## you set the interval to whatever is > best for you > end checkTime > > Best regards > Tore Nilsen > >> 11. jul. 2022 kl. 13:35 skrev Tim Selander via use-livecode >> : >> >> Dear all, >> >> I want to have an LC app running on a computer doing nothing but watching >> the time.
