Access Report Expression that adds a new line between strings

Posted on 2008-06-19

I am making an Access Report that pulls data from an Access query.  Nothing too difficult.  However, the one field is a string that has multiple lines.  For a line break, a square character is used to show to start a new line.  While this works in most applications, access simply reads it in as a character and displays the square instead of making a new line in the textbox that the field is bound to.

Could anyone give me an example of an expression that would simulate hitting return when it finds a certain character in an Access field?

you can use  vbcrlf  to break the line

dim msg

msg="the quick brown fox " & vbcrlf & "jumps over"

msgbox msg

post sample data from your table

Here is an example, however, the text editor on experts exchange accepts the square symbol as a line break...so I'll use [] in place of it.

Example:
"WATCH CUBE                    [] 2-1/4"" X 2-1/4"" X 2""H           []WITH WATCH SUPPORT"

Thinking maybe character is ascii cr or lf. So not full crlf.

Just a thought, if you had this and use the vaue returned from here to display

Public Function ShowCRLF(ByVal sString) As String

    Dim i As Integer
   
    If sString = "" Then
        ShowCRLF = ""
        Exit Function
    End If
       
    For i = 1 To Len(sString)
        If Mid$(sString, i, 1) = Chr$(13) Or Mid$(sString, i, 1) = Chr$(10) Then
            ShowCRLF = ShowCRLF & vbCrLf
        Else
            ShowCRLF = ShowCRLF & Mid$(sString, i, 1)
        End If
    Next i
End Function

Hmm, what am I doing, chr$(13) is same as vbcrlf
So perhaps its just the line feed character you got then chr$(10)

There is also the option of checking for all non readable characters by just checking ascii range. It then depends on what to you want displayed.

Sorry, a little lost in your code.

Could you place in jobDescription (it's the column name) where it would be needed.

Just having some problem following it :)

Simply put, if it reads the character [], it should starting the next part of the string on the next line.

Well, maybe it's not so simple :-P

try this

update TableX set Fieldx=Replace(fieldx, chr(13), chr(13) & chr(10))

or

update TableX set Fieldx=Replace(fieldx, chr(10), chr(13) & chr(10))

if you attach your db here, we can check what the square symbol is chr(9),chr(10) or chr(13)

Sounds like a plan.  Here is a sample database that includes one instance of the square character.  Sorry, I'm not too fluent in VB, so thanks for taking the time.

Ok, your query is based on some sql?

You could put this function in vba code somewhere, then change your sql

select field1, field2, ShowCRLF(jobDescription) as JDescription, field3
from ...

This way it leaves your original data intact

Your report can then use JDescription as the field


But not sure if that is the case though

if you did

select jobDescription from mytable

in a query, what do you get. Do you get square brackets?
If so, if you did

select ShowCRLF(jobDescription) from mytable

what do you get now?

It could be other characters and not return characters

If so then use this to remove it

coming up...

it is chr(10) , use this update query


UPDATE test SET test.PartDescription = Replace([PartDescription],Chr(10),Chr(13) & Chr(10));

will this change the actual database though?  I can't change the database.

SELECT ShowCRLF(PartNum)
FROM table;

This didn't work.  Didn't know what ShowCRLF was.

Just to clarify, I am running a query to create this report.  I cannot change the format of the database at all, I just need to change how it displays on the report.

Thanks!

UPDATE test SET test.PartDescription = Replace([PartDescription],Chr(10),Chr(13) & Chr(10));

This did work, but of course it changes the database.

I might try to have it insert the field into a new table maybe and format it from there...but then I guess that query would have to run everytime the report is ran.

Does this sound like it should work?

then just run a select query

SELECT Replace([PartDescription],Chr(10),Chr(13) & Chr(10)) AS PartDesc
FROM test;

Ok, using your sample

SELECT ShowCRLF(test.PartDescription)
FROM test;


It has removed the square brackets, you need to expand the row to see the text

(this is in the query)

No worries

by the way, I just saw your comment

This didn't work.  Didn't know what ShowCRLF was.

When you paste the method in a vba module, you gotta save that module before you can use it
