How to detect line break while reading input ?

Hi all,
I am reading the user input from standard input.
I want to detect the line break. So that I can stop reading input and proceed processing the string.
Actually I am getting the SQL query as input and after that I am executing the same by passing it to a function.
Pl. do reply me.
   Scanner scanner = new Scanner(System.in);
        while(scanner.hasNext())
             temp=scanner.next();
              sql=sql.concat(" "+temp);
             if(scanner.next=="\n")
                        break;
       System.out.println(sql);
       sqlTool.executeSQL(sql);
The above is not working properly.

But if new line comes, what will be it's value?Empty lines are discarded by the scanner.

How to put line break in the text

Hi guys,
This is a simple problem.i don't know how to concat a line break while creating a text.
I am looping through the results of a query and want to form the text using the results.
For each row of the resultset,I want to create a new line in the text i create.
I was wondering how to put a new line in the text.
I thought I can concat '\n' ,but it does not work.
the code snippet in the procedure is :
for c1_rec in c1 loop
vMsg := ' There are ' || c1_rec.total ||
     ' documents of type ' || c1_rec.doc_type || '\n' ;
end loop;
Please give the solution.
Thanks in advance.

Thank you Mark.
I tried your suggestion.But line break is not working in email.
Here is how my code is
in procedure 1 ,i create the message String as :
for c1_rec in c1 loop
vMsg := vMsg || ' ' || today_str || ' - ' || c1_rec.total ||
     ' Total inbound documents from : ' || c1_rec.target_value || CHR(13)||CHR10) ;
dbms_output.put_line(' ' || vMsg);
end loop;
--here sending mail calling another procedure
sendmail( '[email protected]' ,'[email protected]' , 'Test Subject ' , vMsg );
In Procedure 2( i.e sendmail procedure )
i am preparing email server connection from and to adresses .Then i am preparing and sending message as
crlf VARCHAR2( 2 ):= CHR( 13 ) || CHR( 10 );
conn:= utl_smtp.open_connection( EmailServer, Port );
     utl_smtp.helo( conn, EmailServer );
     utl_smtp.mail( conn, SENDER);
     utl_smtp.rcpt( conn, RECEIVER )
mesg:= 'Subject: ' || SUBJECT || crlf ||
               'Date: '||TO_CHAR( SYSDATE, 'Dy, dd Mon yyyy hh24:mi:ss' )||
               crlf ||
               'From:'||SENDER|| crlf ||
               'To: '||RECEIVER || crlf ||
               'Content-Type: text/html; charset=ISO-8859-1' || crlf ||
               '' || crlf || MESSAGE ;
     utl_smtp.data( conn, mesg );
     utl_smtp.quit( conn );
even now the mail we are getting is not having the line break.I am having line break in dbms output,but not in the mail.
Is there any mistake how I am sending the mail.Or is there any other way we can put line break in the text
Thank you.

File adapter-How to set line break in text file-split record into two lines

Dear Guru's,
I have to solve following problem with XML (with mulitiple records) to TEXT file scenario using file adapter. I have to output for ever ONE data record in XML always two identical lines in text file. Second line should have a little bit different mapping in few fields like date,... So I did duplicate fileds in my output structure in mapping and need to know how to set line break in the middle and see half of structure in first line and next structure half in second line
My output structure in mapping is:
CASHFLOW
- INTERFACE
- GESELLSCHAFT
- ANWENDUNG
- PRODUKT
- VERTRAG
- BETRAG
- WAEHRUNG
- DIRECTION
- BEWEGUNGSTYP
- FAELLIGKEIT
- ZINSFESTSTELLUNG
- ZAHLUNGSTAG
- RENDITE
- INTERFACE2
- GESELLSCHAFT2
- ANWENDUNG2
- PRODUKT2
- VERTRAG2
- BETRAG2
- WAEHRUNG2
- DIRECTION2
- BEWEGUNGSTYP2
- FAELLIGKEIT2
- ZINSFESTSTELLUNG2
- ZAHLUNGSTAG2
- RENDITE2
Question is how can I set on receiving file adapter in Content Conversion Parameters that fields from first structure half INTERFACE...RENDITE should be outputed in one line and fields from second half of structure INTERFACE2...RENDITE2 should start on second line in final text file.
I'm getting at the moment one line only and I need to know how can set line break so that second line starting with INTERFACE2(CA)...RENDITE2 will start in new line.
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000",CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
This should be final output:
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000"
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
My file adapter settings:
RecordsetStructure=CASHFLOW
CASHFLOW.fieldNames=INTERFACE,GESELLSCHAFT,ANWENDUNG,PRODUKT,VERTRAG,BETRAG,WAEHRUNG,DIRECTION,BEWEGUNGSTYP,FAELLIGKEIT,ZINSFESTSTELLUNG,ZAHLUNGSTAG,RENDITE
CASHFLOW.fieldSeparator=,
CASHFLOW.endSeparator='nl'
CASHFLOW.fieldNames=INTERFACE2,GESELLSCHAFT2,ANWENDUNG2,PRODUKT2,VERTRAG2,BETRAG2,WAEHRUNG2,DIRECTION2,BEWEGUNGSTYP2,FAELLIGKEIT2,ZINSFESTSTELLUNG2,ZAHLUNGSTAG2,RENDITE2
CASHFLOW.fieldSeparator=,
It wont help if I add two identical structures in mapping because in output i would see for multiple entries section with first lines only and after that section with second lines only. And CASHFLOW is one part of more complex mapping ...
(This is final output structure RecordsetStructure=HEADER,CASHFLOW,CONDITION,REFERENCE,CONTRACT - more sections with different data and all these should have duplicate lines at the end)
Thanks a lot for any help
Cheers
Marian

Hi Ivan,
right, I did test just for sure.
Putting constant 'nl' into field CASHFLOW-INTERFACE1 didnt help - still getting one line instead two lines.
CA ,"0100" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,2 ,12 ,2009-01-28 ,2009-01-27 ,2009-01-28 ,"0.0000000" ,'nl' ,"GTP1" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,1 ,10 ,2009-01-27 ,2009-01-27 ,2009-01-27 ,"0.0000000"
So there is still question. Is there any way (mapping,...) how to output always 2 lines in text file for one record in XML. It always does 1 record in mapping structure = 1 line but we need 2 lines ...
Example:
Input: 4 records in XML
Output: 8 lines in final text file ...
Thanks to you all guys

VSTO: How to set line break in Ribbon Xml?

Hi All,
I have a button in Ribbon.xml. it looks like:
<group label="myLabel" id="View">
<checkBox id="cbView" label="ViewViewviewviewview" getPressed="cbView_Pressed"/>
</group>
The result is shown as:
The checkbox is too long. My question is : How to set line break in checkbox's label.
Thanks a lot,
By the way, in Ribbon Xml. How to add RadioButton?

Hello Ricky,
The Fluent UI (aka Ribbon UI) doesn't provide any attribute or callback for that. You can try to use an escape sequence "\n\r", but I am not sure whether it helps. Also you may consider placing a text block below the check box control.
You can read more about the Ribbon UI in the following series of articles:

How to handle line break embeded inside CSV column

Hi there,
I am under the pressure to make it work. I already put this question on APEX forum, but on second thought, I think it relates more to PL/SQL rather than APEX since APEX 4.1 already have utility to handle CSV Upload.
If you read it already in APEX forum, please ignore.
I am sorry for that. Thanks for reading.
I need to develop an app that allows user to upload CSV file to a interface table.
The APEX version at my workplace is 4.0.2.
I used the code from
http://dbswh.webhop.net/htmldb/f?p=BLOG:READ:0::::ARTICLE:11000346061523
It all works well till recently I find out
If a column in a CSV file cotain a line break (or new line) e.g. (The tester copy and paste this text which has line break into a column in a spreadsheet)
This is the first sentence.
This is the second sentence.
It will break the “This is the second sentence”. To a new column.
The contents of the CSV viewed in Notepad look as below
Assessment Date,Scheduled Date,Assessment Provider,Assessor Name,Court,First Name,Middle Name,Last Name,PRN Person Record Number,NHI Number,Defendant Attended Y/N,Is Dependent Y/N,Notes,Primary Ethnicity,"Ethnicity Other, please specify",Gender,Currently in Treatment Y/N,Substance of Concern 5,Other Substance Specified
22/09/2012,,Provider Co Name,Warren Edgley,Wellington,,,Salty,2545554,dgsdf,ergerg,,"This is the first sentence.
This is the second sentence.",Japanese,,Female,b,,
Here is the code from the CSV UTIL, please help me to find out how can I replace the line break to a space so that the uploading process is correct.

Yes, exactly. That piece of code believes all CHR(10) occurences are record delimiters.
It is not smart enough to recognize that a CHR(10) within quotation marks are part of the data.
Optimally a solution should keep the CHR(10) rather than replacing with spaces, but that will be a bigger rewrite of the UTL_CSV code ;-)
If you are happy with replacing with spaces, a "simple" solution could be something like:
Declare a boolean variable in upload procedure:
v_within_text_column boolean := false;And use it like this:
 WHILE (v_position <= v_clob_len + 1)
 LOOP
 v_char := DBMS_LOB.SUBSTR (v_clob_data, c_chunk_len, v_position);
 IF v_char = '"' THEN
 v_within_text_column := NOT v_within_text_column;
 ELSIF v_char = CHR(10) AND v_within_text_column THEN
 v_char := ' ';
 END IF;
 v_line := v_line || v_char;
 v_position := v_position + c_chunk_len;
 -- When the whole line is retrieved and not end of file or end of file
 IF v_char = CHR (10) AND v_position < v_clob_len OR v_position = v_clob_len + 1
 THEN
 v_within_text_column := false; -- To be safe always set this on "true" linebreaks
{code}
+(This is untested code just written here in the text editor.)+
It should work by toggling a flag whether you are "within" the quotes or not and then replacing CHR(10) with a space if you are within a text column.
This way we avoid having to go through the clob more than once (it is enough that this code walks the clob one character at a time...)
It will not handle if the clob contains situations like:
{code}
abc,123,"This is a text with a quote from a man who said \"To Be,
or Not To Be\" some hundred years ago",123,xyz
{code}
Escaped quotes would need separate attention ;-)

[solved] How to have line breaks in output of journalctl log

Hello,
How can I have line breaks in the journalctl log output?
At the moment I cannot read most of the log output because it does not fit into my terminal.

You can run

Edit: If you hit 'h' you get help screen

It may be possible to configure the way the journal uses the pager so it wraps the lines by default.
Edit 2: Or maybe it can't be configured.
man journalctl wrote:The output is paged through less by default, and long lines are "truncated" to screen width. The hidden part can be viewed by using the left-arrow and right-arrow keys. Paging can be disabled, see --no-pager and section Environment below.

How to set line break points in JSF Facelets files on NetBeans?

I am running debugger on NetBeans. I can set line break points for jsp files but cannot for Facelets files with extension 'xhtml'. Dose anybody know how to set break points for Facelets xhtml files? Or is it possible to set break points for xhtml filles?
Thank you very much.

You can't. They aren't executable code, they are templates. The only executable code is the part inside #{}.

How to replace line break for comma

Hi there,
i have a string which is like
header1,value1,header2,value2,header3,value3,header4,value4now i have to write the above string to a file which should be like
file.txt should be
header1,value1
header2,value2
header3,value3
header4,value4i can write the string to a file easy, but i need to make the every even number , to line break.
any help
Thanks
R

You may get a better way, but this is how I would do this:
-- split the string on comma
-- iterate through the array using a for i+=2 loop and concatenate every pair of strings with comma-space between.

edit And write the results to a new array of half the length, of course. Then write the new array to the file.

How to skip first records while reading a csv file

Hi,
How to skip the first 5 records while reading csv file.
I have a file which contains first 5 records as dummy records, I want to skip those records and load the rest into RDBMS.
How to achieve this?
Thanks,
Naveen Suram

Hi Guru,
Actually I have converted an excel to CSV format, which is generating first 4 rows as some dummy records. 5th row is my header record. But in hearder record, two column names are same. Thats why while reversing it is giving an error.
With zero in number of columns in header, I am getting the column names as C1, C2...
If not in reversing, can we reject the first records while loading into RDMBS table using an interface?
Thanks,
Naveen Suram

End of line(character) while reading the line

Hi
i am reading the file from the application server by opening the file in binary mode(as it is a tab delimited file)
now when i read the line it wil read character by character. My problem is how to find the end of line now,
i think the end of file will have one end character
what is that character and how to find that character...

Hai,
Use this function module to read the file from application server.
'DX_FILE_READ'
it will read all the line.

How to keep screen on while reading something

While reading some detailed articles on the web in Safari,I face a lot of problem.The screen goes dim and then turns off.
Is there any way by which I can program my mac in such a way that it automatically detects that I am reading some article and the screen doesn't off or go dim ??
Thanks

I don't know of any software that detects when you're reading the screen - that's not to say some doesn't exist.
I'm sure there used to be an option to elect whether the screen should dim before sleeping/screen saving, but I can't actually find it. I'm on an iMac, maybe it's laptop specific and I haven't got one any more to check.
At least if it dims first you've got the chance to touch a key/mouse/trackpad to prevent it sleeping.

How to include Line break in string?

Hello Experts,
I have a requirement like, I have to display the string value in 2 lines in Web UI.
I have achieved that functionality using the below code in CRM Ehp1.
data : str1 type string,
str2 type string,
lv_str type string.
str1 = 'Hello'.
str2 = 'World'.
lv_str = |{ str1 }\n{ str2 }|.
write /: lv_str.
The output is: Hello#World
In web ui, it is displaying in two lines like
Hello
World
But, the special character '|' is not supported in CRM 7.0
Is there anyway for line-break?
Regards
DNR Varma

Hello
I always use cl_abap_char_utilities=>cr_lf as a line-break symbol .

[remote host]>
I need here a Listener for detecting, could someone tell me how i can do it, or which Class or Interface or Methods i should use? Many thanks in advance!!!

I found something that I hope helps:
The java.awt.TextArea could be monitored for changes by adding a TextListener for TextEvent's. In the JTextComponent based components, changes are broadcasted from the model via a DocumentEvent to DocumentListeners. The DocumentEvent gives the location of the change and the kind of change if desired.
Example code :
DocumentListener myListener = ??;
JTextArea myArea = ??;
myArea.getDocument().addDocumentListener(myListener);
Just use the DocumentListener like any other listener. :) Good luck.

How to set HttpURLConnection timeout while reading a stream?

I want it got time out if the connection if lose while i read a stream from URL

 if (contentLength < 1) {
 error();
 if (status == DOWNLOADING){
 if (size == -1) {
 size = contentLength;
 file = new RandomAccessFile(saveTmpName+".tmp", "rw");
 file.seek(downloaded);
 byte buffer[];
 stream = connection.getInputStream();
connection.setReadTimeout(timeout);
 while (status == DOWNLOADING) {
 if (size - downloaded > MAX_BUFFER_SIZE) {
 buffer = new byte[MAX_BUFFER_SIZE];
 } else {
 buffer = new byte[(int)(size - downloaded)];
 int read = stream.read(buffer); // how to set timeout while it is reading stream
 if (read <= 0)
 break;
 file.write(buffer, 0, read);
 downloaded += read;
 if (status == DOWNLOADING) {
 status = COMPLETE;
} catch (SocketTimeoutException e) {
 error();
} catch (IllegalArgumentException e) {
 error();
} catch (Exception e) {

 } catch (Exception e) {}
 if (stream != null) {
 try {
 stream.close();
 } catch (Exception e) {}

Because, there's no FTP client command that allows to do such thing.Socket.setSoTimeout().I agree with you on this one but the OP is talking about the FTPClient API from Apache.
To the OP,
BTW, I have reread the Javadoc about the [*API*|http://commons.apache.org/net/api/org/apache/commons/net/ftp/FTPClient.html] : indeed, there's no setTimeout method, but there is a setDataTimeout method : +Sets the timeout in milliseconds to use when reading from the data connection+ .
