Writing data to New Line in a File

Hi guys,
Im writing data to a file, i want to write data on different lines, not contineously.
My code is writing the data but not the next line.
Please Help. My code is below :
fw = new FileWriter(filename,append);
fw.write(cur_timestamp().toString());
fw.write("\n");
error_data = errorCode + " " + msg;
fw.write(error_data.toString());//appends the string to the file
fw.write("\n");Thanks
Rebekah

You'd still want to use the System property, because other editors might display it correctly, but for the Windows platform, it's acctually incorrect behavior. The separator would be "\r\n". I think on a Mac, it'd be "\r" - so your program would fail again there.

New line in text-files

Hallo,
this I have a problem with writing data in a text-file. How can tell LabVIEW (6.1) to begin a new line in the file?
I already tried the [carriage return] -- constant, building arrays, building spreadsheat strings from array etc.. Everything wit no success.
Can anybody of you help me?
Thanks a lot, Arno

Send an End of line character to the file. You can find an End of line constant in the string pallette.

Appending to new line in text file

I am trying to append text to a new line to a file. I set the append parameter to true and I try to output the new line character after I write the string to the file. However it is still appending the next string to the end of the first rather than in the line below. My code is below. Can someone please help me?
Thanks

try

myFileWriter.write(contents);
myFileWriter.write('\n');
myFileWriter.close();
return true;
catch (Exception e)

Print data at new line in SAP Scripts

Hi,
Is there any way that i can print data at new line in sap scripts. I am looping my data and its printing in the same line but i need to print it at new line. Is there any formating options or any command to do that.
Thanks

Than you must take all the values from the internal table into the different variables and than print them.
In program:
READ TABLE ITAB INTO WA_TAB INDEX 1.
IF SY-SUBRC = 0.
VAR1 = WA_TAB-FIELD1.
ENDIF.
* read all the lines and fill the VAR variables
In SAPScript:
/E LINE_VAR
/P &VAR1&
/P &VAR2&
/P &VAR3&
/P &VAR4&

New lines in a file

I'm trying to find a good way to get new lines in a file, and while this works it also uses 100% CPU and is driving me nuts. At least the profiler says this is .run is using the most, and taskmanager gives it 100%. The file name changes every day.

I don't know what anybody can say other than "debug and profile your code".
It's weird that you have a Thread.sleep in the run method of a TimerTask. Why not just change the scheduling of the task?
This:
while ((sb.append(reader.readLine())).toString() != null) {
    onNewLine(sb.toString());
    sb.delete(0, sb.length());
}(reindented to make it easier to read) is fishy. Even when you reach the end of reader's input, I think it will just loop forever. That's because appending null to a string buffer and calling toString results in the string "null", not the value null. So that while loop will never end.
Good luck.

Block size in tt for writing data to transaction log and checkpoint files

Hello,
what block size is TimesTen using when its writing data to transaction log and checkpoint files? Does it use some fixed block size during filesystem writes?

Although in theory logging can write 2 KB blocks in almost all circumstances it will write 4 KB or larger so yes a filesystem with a 4 KB block size is fine for both checkpointing and logging.

How to write data in differt line in .txt file

Hi all,
I am tring to write data on one file using utl_file,
the first cursor loop write data on first line of the file using
utl_file.put_line(..........................);
end the second cusor loop write the data on secion line of the same file using
utl_file.put_line(..........................);
file format we are given as .txt;
problem we are facing is when we open the file in notepad all the data is showing in one line...
same file if we open another tools like edit plus, word pad etc it showing the write formate( line by line)
Can any one help on this we need to set any setups in note pad????????????/

As others have said it sounds like an operating system difference.
If your Oracle is installed on a unix based server then the file will be written using Unix style newlines which are just Line Feed characters.
In Windows environments a newline is considered to be made of the Carriage Return/Line Feed character pair, not just the Line Feed.
Some applications such as MS Word or Wordpad can read Unix style linefeeds and interpret them as you expect as a Newline. However Notepad doesn't.
When you transfer the file from Unix to Windows, usually this is done using an FTP based mechanism. If you transfer the files using FTP Binary mode, then every byte of the file is transferred as it is on Unix, and the file will essentially be a unix file on a windows system. If, however, you transfer the files (from Unix to Windows) using FTP ASCII mode, then whenever FTP encounters a LineFeed character it will convert it to a Carriage Return/LineFeed pair of characters, so that the file will appear correctly in Notepad. Likewise if you transfer files from Windows to Unix in ASCII mode, then Carriage Return/LineFeed pairs of characters are converted to just a LineFeed character so that the file becomes Unix compatible. Note, you shouldn't transfer binary files in ASCII mode as it can corrupt them, it's only intented for text based files.

How to write new line to a File?

How to write new line to a file?
I have a string to be written to a file. the string contains "\n" in it. But why it is not showing the new line in the file.
I have tryed FileWriter class and FileOutputStream class, but none of them works?
any suggestion please...

Probably using PrintStream::println() is a portable way.
import java.io.FileOutputStream;
import java.io.PrintStream;
public class NewLine {
    public static void main(String[] args) {
     try {
         PrintStream ps = new PrintStream(new FileOutputStream("foo.txt"));
         ps.write("string".getBytes());
         ps.println();
         ps.close();
     } catch (java.io.IOException e) {
         e.printStackTrace();
}Regards,

Writing to a new line in a text files

I have a servlet that collects results from a questionnaire by getting the parameter values of the radio buttons on a questionnaire page. I am trying to store the results of the questionnaire by writing them to a text file. I can get it to write to the files fine but cannot seem to get it to write the next set of results to a new line. I have many different ways but cannot seem to get it to work. Any ideas?
Heres the part of the code that writes to a text file
String lineRead = "";
            int lineCount = 0;
            while((lineRead = input.readLine()) != null)
                lineCount ++;
                String result = request.getParameter("question" + lineCount);
                output.write(result + ",");
                output.write("\n");

Heres the part of the code that writes to a text
file
String lineRead = "";
int lineCount = 0;
while((lineRead = input.readLine()) !=
adLine()) != null)
lineCount ++;
String result =
String result = request.getParameter("question" +
lineCount);
output.write(result + ",");
output.write("\n");
Can you do output.writeln(result + ",");?
Failing that, putting output.write("\n") inside the while loop should do the trick.

New Line in Text File

Hi -
Im using the FileWriter and BufferedWriter classes to output text into a .txt file.
The text I am writing is taken from another text file using the FileReader and BufferedReader classes.
The text is reading from the file, and will also output to the new text file, however it won't insert a new line, it only inserts an 'unprintable' character i.e. an empty square
My code is below - its only starting out so its farily simple at the moment, just reading from one file and outputting to another.
Is there a way i can get the actual new line/carriage return inserted instead of the empty square. (im running Windows XP)
Thanks in advance
import java.io.*;
public class Pad {
private String inputPath;
private String outputPath;
/** Creates a new instance of Pad */
public Pad() {
inputPath = "C:\\OUTBOUND.TXT";
outputPath = "C:\\04'06.txt";
* @param args the command line arguments
public static void main(String[] args) {
// TODO code application logic here
System.out.println("PAD File");
//Read PAD File
Pad p = new Pad();
p.readPADFile(p.inputPath, p.outputPath);
public void readPADFile(String inputPath, String outputPath)
inputPath = this.inputPath;
outputPath = this.outputPath;
//System.out.println(inputPath);
int recordCount = 0;
String record = null;
try
FileReader fr = new FileReader(inputPath);
FileWriter fw = new FileWriter(outputPath);
BufferedReader br = new BufferedReader(fr);
BufferedWriter bw = new BufferedWriter(fw);
record = new String();
while((record = br.readLine())!=null)
recordCount++;
//System.out.println(recordCount + ": " + record);
bw.write(record + "\n");
bw.close();
br.close();
fw.close();
fr.close();
}catch(IOException e)
System.out.println("IOException Error");
e.printStackTrace();
System.out.println(e.toString());
}

I assume by using the
System.getProperty("line.separator") that this will
work independent of platform.Yes. And using bw.println() instead of bw.print() will already do it for you. So all you need to change in your program are two letters.

New Lines within .txt files

Hello,
I'm creating and writing text from a standalone application to a text file, however when using the "\n" command within a string in java, it is outputted as a box, not an actual new line within the text file.
Is there any way of solving this problem?
Thanks

Use a BufferedWriter and the newLine() method. It will use the appropriate newline String for the platform you are running on. In Windows this is "\r\n".

How to write new line on resource file.

Hello Everyone,
Can you please help me add new row on resource file, here is the code i have used to read my resource file.
I have no idea on how to add new line... Please help
private void btnBrowse1_Click(object sender, EventArgs e)

//versionIncrement();
if (txtInputfile.Text.Length > 0)
PathSelection = txtInputfile.Text;
oDataSet = new DataSet();
//now am reading the files fro the path that is selected
XmlReadMode omode = oDataSet.ReadXml(PathSelection);
for (int i = 0; i < oDataSet.Tables[2].Rows.Count; i++)
string comment = oDataSet.Tables["data"].Rows[i][2].ToString();
//the elements array contain all the columns filled
string[] elements = comment.Split('-'); //when it reaches the comma, it will jump to the next line
string font = elements[0]; //Font
string datestamp = elements[1]; //DateStamp
string commentVal = elements[2]; //Comment
string[] row = new string[] { oDataSet.Tables["data"].Rows[i][0].ToString(), oDataSet.Tables["data"].Rows[i][1].ToString(), font, datestamp = DateTime.Now.ToString(), commentVal };
Gridview_Input.Rows.Add(row);

Hello
Sitholimela,
>> Can you please help me add new row on resource file, here is the code i have used to read my resource file.
From your description, it seems that your resource file is a XML format file, if so, you could also have a try to use
LINQ To XML which is easy to operate the XML file to add new row to your resource file, and here is an example to show how to add a new element/row to the specific tree:
Linq to XML Add element to specific sub tree

Pricing Date on New Line Item Added to Order

We have a requirement, for example, if we create an order for 07/19/2010, the pricing date comes in as 07/19/2010 which is correct. The customer calls back and wants to add a line item or 2, to the order on 07/22/2010. The new line items are priced as of the original pricing date 07/19/2010. How do we automatically update the new line items with today's pricing date instead of the old date. Is there an automated way to do this thru configuration. Or do we need to use user exits:
MV45AFZZ - USEREXIT_PRICING_PREPARE_TKOMK
MV45AFZZ - USEREXIT_PRICING_PREPARE_TKOMP
Thanks,
Mark

Hi,
There is no automatic way to populate the pricing date for item when item is added at later point of time. In this case, the pricing date at header is copied to the item. This cannot be achived by configuration.
As you have mentioned, you have to use the user exits relevant for pricing. The user exits you have mentioned are not correct for this purpose. The purpose of these user exits are different. You need to find the correct one with the help of an ABAPer.

New line character in File adapter

I am having a receiver file adapter which generates files with multiple lines.
My problem is when the target file is opened in notepad there is no line break and the lines comes as continous string with small rectangle as separator.This fails the target upload program.
When I remove those small squares in notepad and hit enter and then upload it gets uploaded successfully.
Is there any way to have line break so that new line will be generated each time (the documenation says the by-default it adds new line character then why in notepad it opens like a continous string?)
Thanks in advance.
Regards
Rajeev

Hello
I know by default File Adapter value is line break. But if I open that generated file in notepad, the record does'nt appear on the new line. Instead at the end of each line there is special character added at the end of each record. When I hit enter and deletes that special character and then try to load that file it gets loaded successfully.
So my problem is how to generate the file will give record on the new line. I tried to give 'nl' as endSeparator.
How to give hexadecimal values? I tried giving '0xHH' but that gives error in File Adapter
"Error: Conversion initialization failed: Exception: java.lang.NumberFormatException: For input string: "HH"
Thanks in advance.

Rajeev

How to add new line to the file?

How to print a new line after String1 so that String2 can be written after String1?
- Eugene -

Do you mean...
PrintWriter pw=new PrintWriter(new FileOutputStream("file"));
pw.println(string1);
pw.println(string2);
pw.close();
the println puts a new line after string1.
