Subject: Problem updating memo field
Hi,
I have a form (a subform) with a few memo fields. One of the memofields is
used for
daily reports I receive in Ascii format, and for editing this lengthy report
I have
made a simple "edit-form" with the proper font type and size to maintain the
layout
of the report. The idea is to make a form exactly like the Zoom-form built
into
Access ( Shift-F2), the only difference is that I need a larger text box and
a custom
font. The "edit-form" works well as long as the memo-string is no longer
than approx.
2000 characters.
If the string exceeds this length, the field will not update, and I get the
message
"Could not update, currently locked by another session on this machine".
Anyone got any idea where I've gone wrong?
I use Acces 2000.
Thanks,
Torgeir

The Memo field will accept and handle thirty times your 2000 characters,
however the
recommended process for handling large texts is to link to the file with a
hyperlink.
This from Help ...
"A Memo field can store up to 64,000 characters. Memo fields can't be
indexed
or sorted. If you want to store formatted text or long documents, you should
create an OLE field instead of a Memo field."
So whatever source is generating the texts is maybe the source to link to
and open
in.

Subject: I have a similar problem
Torgeir:
I also have a similar problem--and for the same reason: I too wanted a
bigger look at a memo field, so I also have a second form devoted to a
larger view of the memo field.
Same problem, and I'm running Access 2002, and I just installed the latest
service pack about two weeks ago.
One difference, though: I don't get a message; the changes I make on the
second form simply disappear without warning when I close the second form.
However, should I try to requery the second form, THEN I get a message
saying, "Could Not Update; Currently Locked by Another Session on this
Machine (Error 3188)".
Have you (or anyone!) discovered what this is about? Is it a bug?
Thank you!

Subject: Problems with memo field
I am having the same problem with a memo field, the exact length of the
field now is 2048. It seems to me that that length would be extremely
coincidental if it were not related to a kilobyte, as that is exactly two
kilobytes.
The problem is this data is *not* being pulled from any source document,
such as MS Word or a text file of any kind. These are notes left in specific
customer orders, and the specific customer order having this problem has
been having issues for months, allowing the order notes field to become this
large.
In my opinion, if a memo field is said to be able to handle up to 64,000
characters as posted previously in this thread, then it *should* be doing
exactly that. Office is to far along to be handicapping developers in this
manner, so I will be looking into this issue a bit more to attempt to find a
better resolution than revamping a major part of my frontend.

Please do me the favor of posting any solutions here, and I will do the
same--though I have postponed the search for a solution for the time being
because of more pressing matters.
I did do two things, however: First, I counted the characters in the memo
field, and I discovered that I start to have this problem when the number of
characters in the memo field reaches 1037 (where have I seen that number
before?).
Second, I also created a brand-new database in Access 2002 with which to
experiment:
In this brand new databasee, I created just one table with only 2 fields: A
key ID Counter/autonumber field and a memo field.
I then made only two forms, both identical, each form having the same lone
table as their record source, and with a text box control on each form,
having the same (and only) memo field as their control source.
And sure enough--the same problem happens. So now I know it's NOT because of
some other code or something in my real database!
(And if I remember correctly, I also was able to duplicate the same error in
Access' own Northwind Sample database!)
Any thoughts? Anyone?

Subject: Memo field error
I have a similar problem. My problem originated as a problem with updating a
memo field when the text was longer than 512 characters. I think that I have
found that the source of this problem is in the way that Access handles
references to fields with the syntax of Forms!<<FormName>>!<<FieldName>>. It
seems that these references are passed as strings which are limited to 512
characters.
My attempt at a work-around focused on the face that references to such
fields do not seem to have the same limits in MS VB. I updated the fields
successfully using the following syntax:
Dim NewText
Dim sSQL
NewText = Forms!ChangeMemo!Text
sSQL = "UPDATE tblMemo SET [Text] = "" " & NewText & " "" ; "
DoCmd.RunSQL (sSQL)
This worked in my test application, but when I incorporated it into my real
application I either get the "Could not update, currently locked by another
session on this machine" error message or a dialouge that says, "Another
user has edited this record" and gived me the choices of copying to the
clipboard, saving my information, or discarding my information.
I think that the issue with the error messages is that the DB engine is
recognizing my VB SQL statement and the bound form that I have open as 2
different users whose writes are conflicting.
Does anyone know what is going on here?
