Problem with mailing labels and line feed

I am trying to print mailing labels and suppress optional address lines to eliminate white space while maintaining label alignment. This is what I am trying but it does not work.

I create a function that determines the length of a field (i.e. street) and increments a counter if the length is zero. It also takes a second parameter that detremines whether to reset the counter. I then use the function in the visibility each row of the label table. Example iif(Code.LineLen(Fields!Street.Value)=0,True,False). I place this on the visibility of each row except the last as that is City,State,Zip and is required. On this last row the expession I use is

=Fields!city.Value & ", " & Fields!state.Value & " " & Fields!zip.Value & iif(Code.LineCount<5,StrDup(5-Code.LineCount,vbCRLF),""). What this is intended to do is print a carraige return and line feed for every row that did not print. Instead no line feeds occur. I have verified that the Code.LineCount is indeed calculating correctly (I printed the value). I've removed the conditional to make sure it has no issues but again nothing. For clarification the code block I am using is this.

Public LineCount as Integer=0

Function LineLen(byval LineIn as string,byval IsFirst as boolean) as Integer
if IsFirst=True then

LineCount=1
end if
If len(LineIn)>0 then
LineCount=LineCount+1
end if
LineLen=Len(LineIn)
end Function

So if anyone either knows why the line feeds do not occur or a better way to handle this please let me know. Thanks.

Well I partially figured out this issue. Apparently the StrDup function in .Net does not like carraige returns and line feeds. I wrote my own string dup function and now I get the line feeds.

I would still be interesting in a better way of doing this if anyone knows.

Problem with formatting with CR and LF in a string

Hi,

I'm trying to use carriage return (CR) and line feed (LF) to format a string for use with the msdb.dbo.sp_send_dbmail stored procedure. My goal is to have several lines of text delineated with CR LF. However, it appears that SQL Server 2005 is replacing the CR LF with 2 spaces. The snipped below demonstrates this.

declare @.msg nVarChar(100)
set @.msg = 'this is before the cr ' + char(10) + char(11) + char(12) + char(13) + char(14) + char(10) + 'and this is after the cr'
select @.msg

If I copy the text returned by the select into a hex editor what I see for the portion of the string "cr ' + char(10) + char(11) + char(12) + char(13) + char(14) + char(10) + 'a" is:

63 72 20 20 0B 0C 20 0E 0F 61

I was expecting:

63 72 20 0A 0B 0C 0D 0E 20 61

This is what leads me to believe the CR and LF are being replaced with spaces as it shows hex 20 (SPACE) instead of hex 0A (LF) and hex 0D (CR).

Can someone explain to me how to make this do what I want it to?

Thanks
John

Given this simple test:

CREATE TABLE dbo.CRLF(id int,crlf nvarchar(100))

DECLARE @.msg nVarChar(100)

SET @.msg = 'this is before the cr ' + char(10)+ char(13) +'and this is after the cr'

INSERT INTO dbo.CRLF(id,crlf)VALUES(1, @.msg )

SELECT * FROM dbo.CRLF

I get this if I copy the results from Query Editor:

idcrlf

1this is before the crand this is after the cr

And this ouput put if I Open Table in Object Explorer:

1this is before the cr

and this is after the cr

|||I'm unable to duplicate your results. I get a single line when opening the table in the Object Explorer.

If you add a DECLARE @.LongMsg and set @.LongMsg = @.Msg + @.Msg + @.Msg and then use @.LongMsg as the @.body parameter of the msdb.dbo.sp_send_dbmail your email will be a single long line with no CR LF showing in the text. This is basically what I'm trying to do.

Perhaps there is a server setting somewhere that needs to be tweaked on our server.

Ya it true but you see 2 box kind of symbol when you opened

the table trough Object explore, select the option “Result to Text” in the

Query panel and select the row then output shows like this.

(1 row(s)

affected)

idcrlf

--

1This is 1 msg

and this is

2 msg

this is 3

msg

(1 row(s)

affected)

|||Ok, after changing the option I can see the CR in the results. Thanks for showing me something I didn't know.

However, I'm still having problems with the CR in the email text. Here's another snippit from the stored procedure:

Declare @.Message varchar(200)
Declare @.MessageList varChar(max)

SET @.MessageList = 'Daily Summary Report' + @.CR
SET @.MessageList = @.MessageList+'New Items'+ @.CR
SET @.MessageList = @.MessageList+'--'+ @.CR
DECLARE c2 CURSOR FOR
select MSG from Email.Messages
where Event_ID = @.EventID
OPEN c2
FETCH NEXT FROM c2
INTO @.Message
WHILE @.@.FETCH_STATUS = 0
BEGIN
SET @.MessageList = @.MessageList + @.Message + @.CR
FETCH NEXT FROM c2
INTO @.Message
END
CLOSE c2
DEALLOCATE c2

This builds the body text of the email in the variable @.MessageList. It always puts a CR at the end of the line for the SET @.MessageList lines that are outside of the loop.

Inside the loop, if the message type has messages like "Added UPC 123456123456" it works fine with a CR at the end of every line.

If the message type has messages like "FAILED Client1 20050122 Source TYPE 2: 12 COLUMNS SEMI COLON DELIMITED production" it does not put a CR at the end of each line. If I put CR twice at the end of the line I do get two CR's in the email.

I'm stumped. At this point I have put in an if statement to put 2 CR's at the end of the event types that are not gettting the single CR and that seems to work, but I'm one of those types that like to understand why things work or don't work.

Any more thoughts? And thanks for your help.

Hmmm, I tried deleting a post I just made in this thread, because it seemed no longer relevant after John had made a simultaneous post, and it appears to have deleted John's new post, too.

I think that is a bug in the FORUM software, since I chose only my post when I selected "Delete".

Sorry!
