When running a report..I get the message "Cannot open any more
databases." Run-time error 3048... Has anyone seen this message
before?

If this is Access 97, the solution was to download Service Release 2 from: http://support.microsoft.com/support...cks/Office/97/
If you have the pack or are running a later version, the problem might be
related to the number of domain aggegate calls you are making, e.g. if the
report's query or controls call DLookup(), DMax(), etc. If that's the case,
post back and we will give you a replacement for DLookup().
It's also important to dereference your object variables in your code. For
example, if you have code that uses CurrentDb and OpenRecordset, ensure you
close the recordset and set your object to nothing. This kind of thing:
rs.Close
Set rs = Nothing
Set db = Nothing

Are you opening recordsets or creating variables and not explicitly
destroying them by setting <object>= Nothing after you finish your
code? That would cause you to run out of resources...
I have had the same problem with A2K, in spite of dereferencing everything
and usind ELookup queries etc rather than DLookup. The problem is compounded
by List Boxes, Combo Boxes, & subforms each of which is running an SQL which
gets reported as "Cannot open any more databases."

This error message is sometimes erroneous in that it's actually
*table handles* that you're running out of. There's a pretty good
discussion of this problem (interpreting the error message both
literally and as evidence of insufficient table handles) at: http://dbforums.com/arch/42/2003/6/804659
I don't know that anyone reached a solution in that discussion, but
it raises a whole bunch of issues that you need to consider.

According to the discussion in: http://dbforums.com/arch/42/2003/6/804659
using a recordset variable for a recordsetclone opens implicit
database references. So, this:
Dim rs As DAO.Recordset
Set rs = Me.RecordsetClo ne
rs.FindFirst [whatever]
If Not rs.NoMatch Then Me.Bookmark = rs.Bookmark
Set rs = Nothing
will (in A2K) cause an implicit database reference to be created
that is not released at the end.
The solution is to not use a recordset variable, but to use a With
block:
With Me.RecordsetClo ne
.FindFirst [whatever]
If Not .NoMatch Then Me.Bookmark = .Bookmark
End
That does not have the same problem.
It's also a good lesson -- don't use a Set statement with a
variable if a With block is usable in the same context.

David, thanks for posting the link to this discussion.
The behavior makes no sense to me, but I am still seeing the same result in
Access 2003. It is something that needs further investigation, but does
appear to be an issue with this error.
Appreciated.

Hi all,
At work I created a database which is really helpful. The database is used
by approx 15 users. Everything worked great, until I added some
'scoreboard' forms and reports. I get the "Cannot open any more databases"
error.
The 'scoreboard' form show a matrix of 6 columns, 7 rows. Each cell is
calculated separate by (what I call complex) queries.

Access97 Database
The database is split into a frontend and backend and not connected to any other
database. The database has an unbound report with 15 subreports. Some of the
subreports include Excel charts in unbound object frames. When I add 3
additional subreports, I get the error message that Access can't open any more
databases. Can anyone suggest what may be causing the error message.
Thanks!

I have a report that uses several subreports. The report looks fine in print
preview, but when I send it to the printer, I keep getting this message
"Cannot open any more databases." This happened when I add the last
subreport. Is there a limit on the amount of subreports
you can call from a report? If so, any work-arounds? There is a little code
behind the report, but nothing using recordsets.
