[AccessD] 64-but ONLY front end ?

[Ryan W]

Hi Jim,
  I realize 32 bit is still suggested, but I've hit a wall where it just
doesn't work for us. Between the 4 "primary" (aka most used) forms on the
front end it's quite easy to hit that Virtual Memory wall.  The Main Menu
(switchboard), the Jobs menu (logging in jobs from clients) which can lead
to the reporting menu (which not every one uses but our reporters do). Then
there's the Analytical Menu where all the number crunching is done and QA
overview is done are the ones people are in most of the time.  Then there
are tons of supporting forms with subforms for various tasks related to our
work.

Here are my DB stats:

?currentproject.AllForms.Count
409
?currentproject.AllReports.Count
205
?currentproject.AllModules.Count
33
?currentproject.AllMacros.Count
3
?CurrentDb.TableDefs.Count
626
?CurrentDB.QueryDefs.Count
216


A LOT of those tabledefs are back end (SQL Server). There aren't 409 actual
forms, obviously. Some of my most used forms may have 5-10 subforms on them
so it's easy to see how you could add up to 409 "forms" in the collection.
