Write data to multiple text files after specific size

Hello,
I wrote a code that contineously writes data to a text file. The problem is I am running this VI for long time and therefore this text file is being bigger in size e.g. more than 10MB. I want to split writing data in this text file after max 1MB size. Can anyone help ????
thanks in advance.

You could use the "File/Directory Info Function" in the Advanced File VIs and Function palette to check the size. If the file is too big. close it and create a new one.
I would use the Get File Position since this won't cause Windows to have to do so much. Assuming you are just writing and not setting the file position manually, this will return the size of the file in bytes (file position will always be at the end of the file).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Average Data from multiple text files

I am new to labVIEW hence a little help is appreciated:
I have a 100 txt files with two columns (tab separated) for X and Y value.
I need to average the Y values to generate one single txt file and generate X versus Y graph.
So how do I read the data from these text files? (without having to select each one of them individually) and how to average the data and create a XY graph from it?
Thanks in advance
Solved!
Go to Solution.

Use X-Y Graph.
You were able to get two arrays of X and Y points from text file right?

Trying to write data to a text file using java.io.File

I am trying to create a text file and write data to it by using java.io.File and . I am using JDeveloper 10.1.3.2.0. When I try run the program I get a java.lang.NullPointerException error. Here is the snippet of code that I believe is calling the class that's causing the problem:
String fpath = "/test.html";
FileOutputStream out = new FileOutputStream(fpath);
PrintStream pout = new PrintStream(out);
Do I need to add additional locations for source files or am I doing something wrong? Any suggestions would be appreciated.
Thank you.

This class contained some other functions i've deleted, but i think it still works.
That enables to create a log (.txt file) that you can fill line by line.
Each line start by the current system date. This class was used in swing application, but could work in a web app.

Extracting specific data from multiple text files to single CSV

Hello,
Unfortunately my background is not scripting so I am struggling to piece together a powershell script to achieve the below. Hoping an experienced powershell scripter can provide the answer. Thanks in advance.
I have a folder containing approx. 2000 label type files that I need to extract certain information from to index a product catalog. Steps to be performed within the script as I see are:
1. Search folder for *.job file types
2. Search the files for certain criteria and where matched return into single CSV file
3. End result should be a single CSV with column headings:
a) DESCRIPTION
b) MODEL
c) BARCODE

Try:

Write arrays into a text file in different columns at different times

Hi,
I have a problem write data into a text file. I want to write 4 1D arrays into a text file. The problem is that I need to write it at different time and in different column (in other word, not only append the arrays).
Do you have an idea to solve my problem?
Thank you

A file is long a linear string of data (text). In order ro insert columns, you need to rewrite the entire file, because colums are interlaced over the entire lenght of the file.
So:
read file into 2D array
insert columns using array operations
write resulting 2D array to file again.
(Only if your colums are guaranteed to be fixed width AND you know the final number of colums, you could write the missing columns as spaces and then overwrite later. Still, it will be painful and inefficient, because column data are not adjacent in the file.)

Write Text Data Array to text file

Greetings all. I hope someone can help me as I am really under the gun. The attached vi shows the basics of what I am trying to do. I have already written a vi that takes the Cal Data Array and prints it out in a nicely formatted report. My problem is that the powers that be also want the data saved to a generic text file that can be copied and printed out anywhere they like. As such, I need to save the data to a generic text file in column format such that it will all fit on one page in landscape mode. There are a total of 12 columns of data. I have been trying to create something that would format each column to a specific length instead of them all being the same. No luck so far. Basically, I need columns 1,2,3,8 and 12 to be length of 5. The rest a length of 9. I have tried to place the formatting part in a for loop with the formatting in a case, but it does not appear to work. I really need this quick so if anyone has any ideas, please help. As always, I really appreciate the assistance.
Thanks,
Frank

How can I use Automator to extract specific Data from a text file?

I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY
Random
Text
161 179
bytes of CODE    memory (+                68 range fill )
16 789
bytes of DATA    memory (+    59 absolute )
1 875
bytes of XDATA   memory (+ 1 855 absolute )
90 783
bytes of FARCODE memory
What I would like to have as a final file:
EXCEL COLUMN1
Column 2
Column3
Column4
Column5
Column6
MM/DD/YYYY
filename1
161179
16789
1875
90783
MM/DD/YYYY
filename2
xxxxxx
xxxxx
xxxx
xxxxx
MM/DD/YYYY
filename3
xxxxxx
xxxxx

Is this possible? I can't imagine having to go through each and every file one by one. Please help!!!

Hello
You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);
#     CSV spec
#     - record separator is CRLF
#     - field separator is comma
#     - every field is quoted
#     - text encoding is UTF-8
local $\\ = qq(\\015\\012);    # CRLF
local $, = qq(,);            # COMMA
# print column header row
my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
# print data row per each file
while (@ff) {
    my $f = shift @ff;    # file path
    if ( ! open(IN, '<', $f) ) {
        warn qq(Failed to open $f: $!);
        next;
    $f =~ s%^.*/%%og;    # file name
    @dd = ('', $f, '', '', '', '');
    while (<IN>) {
        chomp;
        $dd[0] = \"$2/$1/$3\" if m%Link Time\\s+=\\s+([0-9]{2})/([0-9]{2})/([0-9]{4})%o;

How To Re-Input More Data To A Text File?

I was wondering if anyone could tell me how to re-input more data into a text file? I don't want to over-write the text file, but just add more data to it. The current code i have is:
import java.util.Scanner;
import java.io.*;
class trialanderror002 {
public static void main(String args[]){
     Scanner input = new Scanner(System.in);
     String str;
FileOutputStream out;
PrintStream p;
try{
     out = new FileOutputStream("c:\\products.txt");
     p = new PrintStream(out);
     System.out.println("Please insert text to be written to file...");
     str = input.next();
     p.println (str);
     p.close();
catch (Exception e){
     System.err.println ("Error writing to file");
Basically, after each time the program is ran, i'd like to insert another line of data into products.txt.
Is there a way for me to loop the program too and not remove the data from the text file?
thanx...

just one more question...
i've figured out the code to retrieve the text file and print it to screen...but how do i go about only printing parts of my text file?
So supposing my text file has 5 lines of data/text etc, how would i make it print the first line?...or the second line?...or the third....etc etc...
the current code i now have is:
package Assignment1;
import java.util.Scanner;
import java.io.*;
class trialanderror002 {
public static void main(String args[]){
     Scanner input = new Scanner(System.in);
     String str;
FileOutputStream out;
PrintStream p;
try{
     out = new FileOutputStream("c:\\trial.txt", true);
     p = new PrintStream(out);
     System.out.println("Please insert text to be written to file...");
     str = input.next();
     p.println (str);
     p.close();
catch (Exception e){
     System.err.println ("Error writing to file");
          try {
          FileReader file = new
          FileReader("c:\\trial.txt");
          BufferedReader buff = new
          BufferedReader(file);
          boolean eof = false;
          while (!eof){
               String line = buff.readLine();
               if (line == null)
                    eof = true;
               else
                    System.out.println(line);

Scheduling multiple tab BO XI3 report needs to save into multiple text file

Hi,
I have BO XI 3 Desktop Intelligence reports, those reports contains multiple tabs. Once after scheduling these reports the output needs to save as different text files (each tab as separate text file). Generally when select output as text file we will get the text file with the data of current tab, but in this scenario I want all the tabs data into different text files. I guess we can do this with macro. But I am not good in macro development, hope somebody can help me.
Could you please help out for the same!
Thanks,
Rama

Thanks Dan.. I made chenges in code as per your suggestion.. its working fine in DeskI -> local PC
But this is not working in InfoView level... when i scheduled the same report its not saving into multiple text files... can you please have look...
macro code as follows:-
Public Sub SaveAsText()
Dim StrTxtPath As String
Dim BusDoc As busobj.Document
Set BusDoc = ThisDocument
Dim BusRep As Report
Dim I As Integer
On Error GoTo ErrHandler
'StrTxtPath = "
xxxx.xxx.xxx.com\common\Reporting\"
StrTxtPath = "D:\Business Objects\Test_Macro\"
For I = 1 To BusDoc.Reports.Count
Set BusRep = BusDoc.Reports.Item(I)
BusRep.ExportAsText (StrTxtPath & BusRep.Name)
Next I
ErrHandler:
Exit Sub
End Sub
When i run this macro through DeskI.. its saving the report as multiple .txt files with respective number of tabs... but the same thing is not working when i tried in scheduling...
Can you please suggest me what are the changes needs to be done...
Thanks in Advance
Thanks,
Rama

How do you read data from a text file into a JTextArea?

I'm working on a blogging program and I need to add data from a text file named messages.txt into a JTextArea named messages. How do I go about doing this?

Student_Coder wrote:
1) Read the file messages.txt into a String
2) Initialize messages with the String as the textSwing text components are designed to use Unix-style linefeeds (\n) as line separators. If the text file happens to use a different style, like DOS's carriage-return+linefeed (\r\n), it needs to be converted. The read() method does that, and it saves the info about the line separator style in the Document so the write() method can re-convert it.

Plotting from a text file like a media player example.jpg ‏61 KB

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

Need to read data from a text file

I need to read data from a text file and create my own hash table out of it. I'm not allowed to use the built in Java class, so how would I go implementing my own reading method and hash table class?

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.

*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

Very simple. A servlet can writes to that file if it has the good rights.
In the servlet get (or post) method, use a code like this:
import java.io.*;
protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
try {
String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
         PrintWriter writer = new PrintWriter (filePath);
        //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
        writer .println("aString");
       writer.flush();
        writer .close();
    } catch (Exception e) {
       e.printStackTrace();

Dim p_AcroApp As CAcroApp
Dim p_VDoc As CAcroAVDoc
Dim p_DDoc As CAcroPDDoc
Dim IsOk As Boolean
Set p_AcroApp = CreateObject("AcroExch.App")
Set p_VDoc = CreateObject("AcroExch.AVDoc")
Call p_VDoc.Open(srcFilename, "")
Set p_VDoc = p_AcroApp.GetActiveDoc
If p_VDoc.IsValid Then
Set p_DDoc = p_VDoc.GetPDDoc
' Fill in pdf properties.
p_DDoc.SetInfo "Title", Format(Date, "dd-mm-yyy")

2) to be able to set the font size of the destination file ( destFilename)
Am using Adobe Acrobat 7.0 Type Library
Kindly Help.
Thanks in advance

We didn't say it doesn't work. We said it isn't supported.
There are a number of other ways to make a PDF. The one which would
give the most control is if your application directly printed to GDI,
controlling the font directly. This could print to Adobe PDF.
You could look for an application that gives control of font for
printing.
You could use a text-to-PostScript system and distill the result. You
could even look for a non-Adobe text-to-PDF.
Working in the unsupported and dangerous world you chose, the font
size for text conversion is set (and this is very bad design from
Adobe) in the settings for Create PDF > From Web Page. There is no API
to this.
