Dear Chris:
Likely, you want to run an "action query", right? Not one that returns
results for you to look at, but one that changes the database, inserting,
deleting, and or updating things.
I recommend you create a separate Access file whose startup is to perform
this action and just use the scheduler that comes with windows. It can open
that database which will perfrom the action. The database can close itself
if desired when it completes. You may want to leave some message that it
was done, perhaps sending an email.
