I'd like to take some of the applications in the office out of the Windows Scheduler, and just put it in a batch file that waits until a specified time.

I already use Timeout for certain tasks. And there are variations of this, out on the web.

But I haven't found anything like a WaitUntil command. I'm pretty sure I could build it in Harbour/Fivewin, within a week. But since there doesn't seem to be an existing command out there, or maybe it's more difficult than it seems on the surface.

Can anyone think of a reason that an executable that runs like

 WaitUntil <Day> <Time Range>

e.g.

 WaitUntil Mon "13:50" "14:10"

would be difficult?

Unfortunately, it doesn't address the specification of a specific time. These are just variations of timeout, where you specify the number of seconds.

I'd want a child program or batch to run, e.g. at 11:15 am, regardless of when the parent calling batch starts. So we don't know the number of seconds, in advance.

There has to be some reason why a utility that specifies the time to run something is so rare. There must be some inherent difficulty, or maybe people prefer to use the windows scheduler because it's already there.

I think I just have to hack around, do some coding, and become more familiar with the problem.

Thanks, Antonio.

Looks like this is it.

You can build it using FWH this way:

example of use (from cmd.exe)
tarry 21:26

tarry.prg

Thanks Antonio,

But unfortunately, it's not exactly what I'm trying to build.

Anyway, I'm very close. I'll share the code shortly.

Hi Antonio,

This is what I was (unsuccessfully) trying to describe.

https://raw.githubusercontent.com/HBEnt ... tUntil.prg

The executable WaitUntil.exe is also on that hub.

I haven't fully tested it in more than 4 circumstances yet, but the syntax is

 WaitUntil <Day> <Time>

So, in order to wait until Friday at 1:15 pm, you would type

 WaitUntil "Friday" "13:15:00"

Regards,

This works for me.

waituntil.prg

Looks good, I'll put it through its paces, thanks.
