[AccessD] Updating a specific record using VBA.

I looked at his message and I have the same problem.  Sometimes fooling with
Menu, Format, Unwrap Text will correct this but it didn't help.

Jurgen,

I did not read through your original mail because it appears in my reader
(Outlook 2007) as one big line and I did not feel like reformatting it to
read it.  Anyone else getting Jurgen's emails as one big line (it does wrap,
but still).

I did not know about the ODBC issue with Jet.  I never use ODBC, but it is
good to know.

Thanks,
Bobby

Other than the redundant trailing semi colon and the incorrect tablename,
your SQL now evaluates to what I posted previously in this thread.  I did
not specify the dbFailOnError parameter, suggesting instead a check on the
database object variable's RecordsAffected property since that allows one to
confirm the update and hence, a means to verify the absence of an error.
Also, there was an unrectified bug acknowledged by M$ relating to the use of
the dbFailOnError parameter against ODBC tables with Jet 3.5 and 3.51:
http://support.microsoft.com/kb/195226.  It can also trigger an IPF and
crash Access with older operating systems:
http://support.microsoft.com/kb/180348.  dbFailOnError is useful for
development purposes because it will give a developer a meaningul error
message explaining the reason for the error and provide a debugging tool.
The error is far less useful to a user as it is too cryptic.  For these
reasons, I nearly always get rid of the parameter prior to delivery.
 
If you don't know how many records should be affected, which is not the case
here, then the dbFailOnError raises a trappable error that can be used to do
something like roll back a transaction should a block of records all need to
be processed concurrently.

In looking at my original example, I left out a couple of quotes. Here's>
the corrected version of the sql:> > Sql="UPDATE tablename " & _> "SET
APLIDLoadedNumber = " & lngAPLID & ", " & _> " APLIDLoadedDesc = '" &
