Batch running of Access

I have been having a lot of issues getting a windows scheduled process to work properly on a remote server.

The process worked for years. Effectively what it does is update one table in an Access database using a csv file; that table is linked to a Quick Books database table. Then it exports the contents of three Quick Books tables (all linked to MS Access) to csv files.

All this is initiated from a .bat file, with is command:

"C:\Program Files\Microsoft Office\Office11\MSACCESS.EXE" "C:\C_LSS\DB\Linked_to_LSS.mdb"  /x "LSS_MACR_Mo-1"

I realized today that in using GotoMyPC to access the remote computer, that I have been leaving Access OPEN in that computer overnight when the scheduled process runs.

When I look in the morning, Access is open & it is asking if I want to update a table, etc. Of course, I want all that to run transparently overnight.

Can I be causing issues by leaving Access "open" on the remote machine?

Thanks

In my experience launching an Access macro via Scheduled Task spawns a new Access process on the machine.  When you leave Access open are you leaving the same db open?  E.g. are you accessing Linked_to_LSS.mdb during your GoToMyPC sessions and leaving it open?

...and do you have Warnings turned off in the Macro or in any procedures that are called from the Macro?

Your macro needs to explicitly close Access as the last step.  It also needs to turn warnings off so you don't get any notification messages.

Leaving Access open this way could interfere with the ability of other users to open objects in design view.  It could cause other update conflicts depending on what task Access is running.

How do I turn warnings off in the Marco (& queries it runs)?

How do I close Access at the end?

Access 2010?  In Macro design, click on the Show All Action ribbon option.
Now, you should see SetWarnings as an available option in the list of Actions.
SetWarnings No   <-- turns warnings off
SetWarnings Yes  <-- turns warning on

You'll also see an action named
QuitAccess

Make sure that's the last action in your macro as it will close the db and exit the Access application.

Even though this macro runs unattended I like to always include a line that sets the hourglass on whenever I set warnings off.  This is a visual clue to me should the macro stop for some reason that the warnings are still off.  I have two macros in every application (in most apps, they are the ONLY macros).  One to set warnings off and the hourglass on and the second to do the opposite.  This gives me an easy way to modify the settings.

I do this because leaving warnings off is deadly dangerous when you are developing.  If you close some object without explicitly saving it, Access will silently discard your changes.  Bye-bye 4 hours of work.  With warnings on, Access will prompt you when you close an object to remind you to save when you have changed it.

I understand both of your inputs.

As I said in the posting, a slightly different version of this Macro has been running, unattended, every night, for about 6 years.

No problems.

So I don't know what to do.

I don't think you answered my question from yesterday.

.....When you leave Access open are you leaving the same db open?  E.g. are you accessing Linked_to_LSS.mdb during your GoToMyPC sessions and leaving it open?

I just discovered the original macro HAS SetWarnings No.

So I'm going with that on this one; see what happens tonight.

Thanks
