I am having problems trying to assign the contents of a Memo table
field to a String variable in VB using the following code:
Private Function udfBuildSQL(SQL ID As Integer) As Variant
Dim rs As Recordset
Dim db As Database
Dim rSQL As String
Dim strSQL As String
Dim fld As Field
Dim fldLen As Long
Dim fldOffset As Long
Dim varChunk As Variant
Const cFldLen = 100
Set db = CurrentDb
rSQL = "SELECT * FROM tblSQL WHERE SQLID = " & SQLID
Set rs = db.OpenRecordse t(rSQL)
Set fld = rs.Fields("SQLS tring")
fldLen = fld.FieldSize
fldOffset = 0
Do While fldOffset <= fldLen
varChunk = fld.GetChunk(fl dOffset, cFldLen)
strSQL = strSQL & varChunk
fldOffset = fldOffset + Len(varChunk)
fldLen = fldLen - Len(varChunk)
If Len(varChunk) = 0 Then
Exit Do
Else: End If
Loop
udfBuildSQL = strSQL
End Function
Although the GetChunk retrieves the data correctly, the strSQL
variable doesn't take more than the first 250 or so characters. At
first I thought I might be hitting a similar limit to the 255
character maximum for a text table field, but have since confirmed
that this limit does not apply to string variables.
I have tried other methods to populate the strSQL variable, but it
still is limited to the first 250 or so characters.
Any suggestions or solutions would be greatly appreciated.
Thanks

I find
DLookup("SQLStr ing","tblSQL ","SQLID=" & SQLID)
will return the full string, even for a memo field longer than 250
characters.
I'm using Access 2000 - what about you?

Hi
I am trying to filter a table of users to select only those records
whose roleID matches a value in an array. There could be any number of
IDs held in the array from one to a few hundred. The array is
generated by splitting a comma delimited memo field from a second
table in an Access DB. I can split the memo field OK, I can
response.write its values, but what I now want to do is add a value
from another table to my reponse write...

I want to create two buttons on a form. One would allow the user to
Copy the contents of the current records memo field, the other would
allow them to print. I set up a report based on the memo field, and
it works. But, it seems wrong since I had to create a huge text box to
accommodate memo fields with a lot of text.
Thanks for any help,

Okay, I checked with usual suspects and I'm still frustrated.
..txt file, fixed width. About 88 fields of varying length. All text
fields. It will only let me add seperators to about the 410th position but
there are 420 positions.
What's going on?

I have a field, data type Memo, in a job details table. I have a text box on
a report which I need to print the contents of this field. My problem is
that the text box will only display 255 characters. How can I get the report

Thanks for any help out there.

If I execute that :
Dim Temp as string = "This is a text"
Dim sw As StreamWriter
Dim fullFileName as string = "c:\text.txt"
sw = New StreamWriter(fullFilename)
sw.Write(temp)
sw.Close()
the resulting file 'Text.txt' has the same length than the string 'temp'.

A little while ago Ron P kindly responded to my inquiry on how to copy
the first line of memo field into a text field, using a query:
left(,instr(1,,vbCrLf)-1)
This is great, but I would like to do this on a form, so that the
person entering the memo can use a button to paste the 1st line to a
title (text) field. I'm having trouble setting up the code to do this.
I'd also appreciate some ideas on how to get the 2nd and 3rd lines...

Hello,
I'm looking for a way to parse/format a memo field within a report.
The Access 2000 database (application) has an equipment table that
holds a memo field. Within the report, the memo field is printed within
the detailed area. The problem is, the apllication is not setup
properly, thus the users are entering data within the memo field as:
location1 1/1/2005 1/1/2006

I have a Memo field in a table to hold notes from a conversation a
social worker has had with a client (this is for a non-profit).
If the user needs to update the memo field, I need to find the
original record (which I am doing fine - getting the correct key)
and
I need to update the "notes" with the new value from the form, which I
store in a String Variable.
(I've tried storing in a Variant variable; didn't work for me)
