Using Access2000
I have an application that is running 24/7 and I would like this application
to perform some routine housekeeping task at midnight.
What would be an efficient way of doing this; of detecting when midnight
arrives? (Without having a form timer check every minute or so to see if
midnight has arrived yet.)
Would a CallBack Funtion be useful?
Thanks

When it intitiates the first time, see how long it takes to midnight and
adjust the timer interval to that length. Maybe flag that machine as
the one to execute the housekeeping.

Maybe schedule a machine to fire up at midnight and pass a /x (macro)
parameter on the command line that lets the app know it is to do the
cleanup or a user/password combo. See "Startup command-line options" in
help.
I'm not sure how a dumb computer can recognize when midnight arrives
without some sort of timer or scheduler.
Thanks

On a form's timer event, ask if Now() is equal to midnight; if so, run your
code, if not, reset the timer to 1000.

Alternatively, use the IsWerewolf() function.

Oops. Didn't read the "without". Nevertheless, I don't see that as
inefficient, but, how about setting the on timer to 1000*60*60*24?

You are correct in thinking that you do not want to waste all that
processing time by checking the time every second. Assuming that the
task does not need to run exactly at midnight, then why not check it
every 30 minutes or so? After you run the task, set a flag in a table
for the current date so you know it's done and you won't repeat it.

My bad. I think Ken Getz had written some sort of function like,
IsWitchingHour( ), but I've lost my copy of the Access Developer's Spellbook.

GGerard,
Nope. We did this at Schwab for an app that had to log in to Oracle and
pick up some data that was ready after 4am. We could run our job any time
after 4am but had to be done processing by 7am when the client's staff
arrived. What we did is leave a machine running the app with a form timer
that sat idle until the scheduled start time for the job. The only
interface was a means to reschedule the job and an options form that let the
client enable or disable some of the steps in the job that was run. So,
form_timer is what worked for us.
We also noticed that running doevents in our loop meant that the machine was
fairly responsive otherwise and could be used off-hours as a spare machine
even though Access was idling away running our form_timer event.

Can you isolate the housekeeping chores into a separate application
and launch that application at midnight using the Windows Task
Scheduler?
