How do I read txt file and add items to dropdownlist or checkbox

I want to add items to a dropdown or check box by reading from a text file(and select one of them). (I donot use any table or database). The list of items is sometimes upto 20MB and hence cannot populate using session bean.I want items to be added to either checkbox or listbox during a button action. I have done this for textarea but unable so far to acheive for checkbox or listbox. I use following code which does not work:
public String button3_action() {
try{
FileReader fr = new FileReader "F:/CreatorProjects/checkboxtst.prs");
BufferedReader br = new BufferedReader(fr);
String s;
while((s=br.readLine())!=null) {
dropdown1.setValue(s);
br.close();
fr.close();
}catch(Exception e) {
e.printStackTrace();
return null;
I know I cant just transplant textarea code for dropdownlist or checkbox.
Any help is greatly appreciated.
Thanks.

I am able to read from txt file to a listbox if i write in sessionsbean1:
try{
FileReader fr = new FileReader("F:/CreatorProjects/checkboxtst.prs");
BufferedReader br = new BufferedReader(fr);
String s1="";
String s="";
while((s=br.readLine())!=null) {
s1 = s1+s;
s1= s1+"\n";
disOptions = new com.sun.rave.web.ui.model.Option[] {
new Option(s1,s1)};
diseases = new String[] {};
fr.close();
br.close();
catch(Exception e) {
e.printStackTrace();
But I get all data in one line!! if I click submit button text area gets all. How to display items in each line????Please help...

Reading .txt file and non-english chars

i added .txt files to my app for translations of text messages
the problem is when i read the translations, non-english characters are read wrong on my Nokia. In Sun Wireless Toolkit it works.
See the trouble is because I don't even know what is expected by phone...
UTF-8, ISO Latin 2 or Windows CP1250?
im using CLDC1.0 and MIDP1.0
What's the rigth way to do it?
here's what i have...
String locale =System.getProperty("microedition.locale");
String language = locale.substring(0,2);
String localefile="lang/"+language+".txt";
InputStream r= getClass().getResourceAsStream("/lang/"+language+".txt");
byte[] filetext=new byte[2000];
int len = 0;
try {
len=r.read(filetext);
then i get translation by
value = new String(filetext,start, i-start).trim();

Not sure what the issue is with the runtime. How are you outputing the file and accessing the lists? Here is a more complete sample:
public class Foo {
     final private List colons = new ArrayList();
     final private List nonColons = new ArrayList();
     static final public void main(final String[] args)
          throws Throwable {
          Foo foo = new Foo();
          foo.input();
          foo.output();
     private void input()
          throws IOException {
         BufferedReader reader = new BufferedReader(new FileReader("/temp/foo.txt"));
         String line = reader.readLine();
         while (line != null) {
             List target = line.indexOf(":") >= 0 ? colons : nonColons;
             target.add(line);
             line = reader.readLine();
         reader.close();
     private void output() {
          System.out.println("Colons:");
          Iterator itorColons = colons.iterator();
          while (itorColons.hasNext()) {
               String current = (String) itorColons.next();
               System.out.println(current);
          System.out.println("Non-Colons");
          Iterator itorNonColons = nonColons.iterator();
          while (itorNonColons.hasNext()) {
               String current = (String) itorNonColons.next();
               System.out.println(current);
}The output generated is:
Colons:
a:b
b:c
Non-Colons
a
b
c
My guess is that you are iterating through your lists incorrectly. But glad I could help.

Reading .txt files and put it into a TextArea

Hi all,
I got a problem! I have to make something like a messenger.
I want to put the written text into a .txt file, after that I have to get the text out of the .txt file and put in into a TextArea.
I would ike it to to that like this:
">User 1
Hello!
>User 2
Hi!
Now here are my questions:
1: What is the moet easy way to do this ?
2: How could i put Enters into a .txt file with Java ?
3: How could i read all the text from the .txt file and put it into a TextArea WITH ENTERS ?
Thanks for your help!
Greetings, Jasper Kouwenberg

use JTextArea.read(new FileReader(fileName)) for reading.
and JTextArea.write(new FileWriter(fileName)) for writing.
The enters should be ok if the user press enter and adds a new line ("\n") to the text area component.
It will save the enter in the text file and load it correctly back to the text area.
If you want to add enter programmatically just add "\n" string to the text area component.

How to encypt a .txt file and how to decrypt a same .txt file when i need

My requirement is i want to encrypt a .txt file and
keep it in some folder. In that file we put database connection
information. when ever we need that file we have to access it and decrypt
it. with that decrypted values we have make connection with database.
i am sending a code in which i wrote both encyption and decrytion in same file, but i want to do it separately.

(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

Write and read txt files and catch the exceptions

hey everyone, im in a bit of a bind. im trying to set up this try catch statement. here is what i have for code so far.
import java.util.Scanner;
import java.io.*;
public class Warning
    //   Reads student data (name, semester hours, quality points) from a
    //   text file, computes the GPA, then writes data to another file
    //   if the student is placed on academic warning.
    public static void main (String[] args)
     int creditHrs;         // number of semester hours earned
     double qualityPts;     // number of quality points earned
     double gpa;            // grade point (quality point) average
     String line, name, inputName = "students.dat";
     String outputName = "warning.dat";
     try
          Scanner FileScan1 = new Scanner (new File("students.dat"));
          // Set up scanner to input file
          // Set up the output file stream
          // Print a header to the output file
          outFile.println ();
          outFile.println ("Students on Academic Warning");
          outFile.println ();
          // Process the input file, one token at a time
          while (FileScan1.hasNext())//there is another line...
              {               // Get the credit hours and quality points and
               // determine if the student is on warning. If so,
               // write the student data to the output file.
          // Close output file
     catch (FileNotFoundException exception)
          System.out.println ("The file " + inputName + " was not found.");
     catch (IOException exception)
          System.out.println (exception);
     catch (NumberFormatException e)
          System.out.println ("Format error in input file: " + e);
}I am pretty sure the layout is good to go, but first and foremost that try statement is hanging me up. Could someone give me some suggestions about how i should set this up.
i want to read in this students.dat file, then output another file called warning.dat.
Thanks i really appreicate the help.

no, i was really hoping to just see if the way it is
set up it will be doable, that way i wouldn't be
working on code that was impossiable to sort through
properlyFair enough.
One thing I'd suggest is that if you're really basically only going to be printing the exceptions, and since that is the top-level method (main) --
I'd instead just add some "throws" clauses to main, get rid of the try/catch stuff, and just let the VM handle the exceptions for you. It will print them, just like you're doing, except that it will also print the stack traces, which you are not doing.
If you're going to handle exceptions, it's better to actually do something about them rather than just print them - otherwise you might just as well let the runtime do that for you.

How to create a text file or XML file and add content through code into it...

Hi Everyone,
How to create a text file and add content through the code to the text file eform javascript ......orelse can we create a text file in life cycle designer...
Else say how to create a new XML file through the code and how some content like Example "Hello World".

You can create a text file as a file attachment (data object) using the doc.createDataObject and doc.setDataObjectContents:

http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.528.html
You can then export the file with the doc.exportDataObject method:

This won't work with Reader if it hasn't been given the file attachment usage right with LiveCycle Reader Extensions.

Read from .txt file and output the content as two arrays

I am using the contoured move to control the x-y stage. The trajectory datas for x and y axis are generated using my interpolation program and it is stored in a .txt file as two columns. What I want to do is read .txt file and output the content of this file as two arrays. Is there anyone has any ideas? Thanks, the .txt file is attached.

Hi Awen,
This is quite easy to do, you can merely use the "read from spreadsheet file" function to get a 2D array (2 columns and n rows) and then use the index array function to get whatever row/colums you want..
Hope the attached VI helps you

How can I read a file with ASCII Special Character into a SQL table using SSIS 2008?

I've tried everything to read this file and am getting no where. Help how can I read this file and load a SQL table?
RS - AscII - 30 (Record Separator)
GS - AscII - 29 (Group Separator)
Thank you for your assistance - Covi
Mark Covian

We can use script component as source/transformation to read the text file and assign the contains to a string. Split the string by chr(30) i.e RS and finally stored into an array or write to the output buffer of the script component.
For example on how to use script component refer this link

Mike,
you were right, you may not specify the extension of a file.
Another thing i detected is that the loop of my data start with the index 1 instead of 0 !!!
In this scenario, i have to read all the lines of the file and each time i should do a SQL-query,
so that i can use the result to build my sales document.
Do you know if it this is possible or have you any idea how to do this ?
thx,
Mario

How to recognize string in txt file and set it as variable

Hi,
I have txt file and somwhere in it string starting with:
data directory....:
How (using batch file) find it in the text, read and set the value as a variable? I mean the string is:
data directory....: c:\datadir
where what I mean value is in this case "c:\datadir". So I want batch file to read the txt file, find string starting with "data directory....:" and then set "c:\datadir" as a variable.
Best, mac

It's not very intuitive to do this sort of thing in a batch file. If you have the option to use PowerShell instead, I'd highly recommend it. It's the new way for performing command-line tasks in Windows, and there's no need to struggle with the old command
prompt anymore.
Here are PowerShell and batch examples of doing this type of string parsing:
# PowerShell:
$dataDirectory = Get-Content .\test.txt |
ForEach-Object {
if ($_ -match '^\s*data directory\.*:\s*(.+?)\s*$')
$matches[1]
break
$dataDirectory
# Batch file:
@echo off
setlocal EnableDelayedExpansion
set DATA_DIRECTORY=
for /F "tokens=1,* delims=:" %%a in (test.txt) do (
set PROPERTY=%%a
set PROPERTY=!PROPERTY:~0,14!
if /I "!PROPERTY!" equ "data directory" (
set DATA_DIRECTORY=%%b
:RemovingSpaces
if "%DATA_DIRECTORY:~0,1%" neq " " goto :SpacesRemoved
set DATA_DIRECTORY=%DATA_DIRECTORY:~1%
goto :RemovingSpaces
:SpacesRemoved
echo %DATA_DIRECTORY%
endlocal

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.
