[AccessD] Clean Shut Down of Access When Left Open in RDP

Tue Aug 7 12:28:34 CDT 2018

Sorry, it is called the "Task Scheduler" in Microsoft vernacular. 

Many years ago I did run into some problems using this type of function, in MS Access but I may have configured it incorrectly. This may not be the best idea but I would be tempted to just "lock" the data file (administration over-ride), changing file to read-only and leave it at that. 

Use to do that when working late nights on a client's servers and all the users connection had not been closed. It may have confused some user who wondered what happened to the record they were working on, before they went on holidays but no data files ever became corrupted via a backup or reboot.

I've never found it to be an issue.

 I check once a minute.   In the past, I just used to do a DCount() on a
table called tblAppShutdown.   If I found a record, I would start a
shutdown.  Later I generalized that into a pair of procedures and a single
table to hold locks for various resources such as the app, records,
printers, etc.  I've got an article on EE covering that.

 I'm not sure I understand the cron job; this is not something that can be
external to the app.  It boils down to every so often your app needs to
check for some type of flag, be it a field, record, file on disk, etc. and
if it finds it, starts a shutdown.

Jim.

How great of impact does this have on the application's performance?

Can a server based cron job be used as it take very little resources and can
be centralized within the network?

Thing is, it doesn't have to be hooked to every form.

 Open a hidden form in the background, set a timer there, and check for a
shutdown flag once a minute.   Also monitor screen.activeform and
screen.activecontrol to check for activity:

me-or-inactivity

 You can then loop through the forms collection and start closing them.

 The biggest problem however is how to handle a msgbox that is currently up.
Form add/edits you can easily un-do, but handling a popup dialog is a
problem.
