Reading/getting external .txt files

Hi,
I want to display the content of a .txt files (which is located in the src folder) inside a TextBox (or ChoiceGroup, or Form). How do I do this yea? For instance, the TextBox constructor is TextBox(String title, String text, int maxSize, int constraints) rite, how do I fit in the file reading function or value that I get from reading the .txt file into it yea?
Thanx!

what do u mean by build the .txt file into the jar?{color:#0000ff}http://java.sun.com/docs/books/tutorial/deployment/jar/index.html{color}
i tried the examples from ... ...In future, please do not post on long-dead threads. One of those threads you posted on was from 2002.
Reviewing your initial post and the silly question about the TextBox constructor, I think you are not quite ready for this task. You need to go back to basics and learn the Java language. The Sun Java Tutorials are a good place to start.
This comment is not meant to discourage you, it is a statement of fact. A good foundation is a must for any developer, or indeed in any sphere of activity.

How to read in text string pairs from an external txt file?

I have an external txt file containing 26000 pairs of strings in the format
string1a   string1b
string2a   string2b
string26000a string26000b
all strings are always 4 characters in length. For example,

How can use TestStand 2013 to input this data into local string array varaibles? I also have legacy testers running TestStand 3.5, so I need a TestStand 3.5 solution as well. Thanks in advance for any ideas. Hopefully this can be done in TestStand without the use of LabView or LabWindows/CVI.

Daniel E., thanks for the reply.
     It is very frustrating to have to implement workarounds in order to access text in an external file when using TestStand. TestStand already reads in text ini files, so it would probably take a TestStand software developer all of 1/2 day to write the code and 1/2 day to debug it. Here I will restate the obvious. Engineers have to deal with data, sometimes data generated from other applications. Sharing data in a text file is one of the most basic functions (and one of the easiest to implement). When I think of all the effort needed to support ActiveX, but NI did not see it fit to give TestStand users simple text file read/write functionality, it does not make sense to me. Maybe it was too simple or mundane a task so it did not get developed? Whatever the reason, I think users of TestStand deserve this basic functionality.
     Even if TestStand cannot read the data directly into array variables, it should provide some mechanism to read the text from the file, either line by line or all file text into a string, so the data could then be parsed into the array variables I need.
     I will pursue a CVI or LabView solution. Please also know that I am not directing these comments at you, I do appreciate your reply.

List component and external .txt file

Hi,
Is there a way to load item labels of a list component from
an external .txt file?
Thanks

Thank you very much Marghoob. It worked!

AS3: outputting trace() content to external txt file

the question's in the title. ive got a swf but i've gotta run
it on a nokia n800, which means trace() content will be lost and -
boy! - do i need it!
so how can i set my swf up to output its trace content to an
external txt file?

hello kglad
well, not 'lost' thats misleading, sorry. i mean: the swf
will be running on a browser outside the flash authorising
environment so the output window won't be accessible, therefore i
need a way of printing out the trace() output to another source.
the help files say that trace() can output to the output window OR
to an external txt file. only it doesnt actually go on to say quite
HOW you can output to said external txt file, rather
irritatingly..

Calling a variable from a external txt file that is equal button name

Hello
I have a variable in an external txt file that is = the name
of my button. I have loaded the file in to flash in an object
called my_lv.
How do I make line three in the code valid ?
_root.map.name1900.onRollOver=function() {
this._alpha=20;
txName=my_lv.+(this._name); // this line is wrong!! I need
to place name1990._name in side the ().

do you have an object called "my_lv" and a child object have
named as "name1900" . ie "my_lv.name1900"\
if i am right then...
>> txName=my_lv.+(this._name); //
should be
txName= eval("my_lv."+ this._name)

How to get a txt file output of Bookmarks or Annotations

I just tried to get a txt file report for the bookmarks. but its not working.
var root = this.bookmarkRoot;
var Report = new Report();
PrintBookmark(Report, root, 0);
Report.save("/c/temp/newreport.txt");
function PrintBookmark(Report, Bm, nLevel)
Report.writeText(Bm.name);
if (Bm.children != null)
for (var i = 0; i < Bm.children.length; i++)
PrintBookmark(Report, Bm.children[i], nLevel + 1);
This is the result i got in console.
NotAllowedError: Security settings prevent access to this property or method.
Report.save:5:Batch undefined:Exec
Whats wrong i did?

First of all, a Report is a PDF that you can generate with JavaScript, not a text file. It might be better to create a text data object (doc.createDataObject), which you can then export (doc.exportDataObject).
Edit: corrected mistake

How to read an external XML file in a indesign Plugin?

Hi All,
Can you please guide in reading an external XML file in a indesign Plugin in MAC system. I am an windows user.We are using this file for reading some inputs.
Thanks,
Daniel

Hello Daniel,
I am uncertain about the actual question. If you are developing a plug-in or otherwise interfacing with the guts of ID, I suggest asking the question in the SDK forum:
InDesign SDK Forum
Otherwise, what is it you are wanting to know concerning importing XML into InDesign?

Apostroph and euro sign not read corectly from txt file

apostroph and euro sign not read corectly from txt file.
my code is like this:
FileInputStream fis= new FileInputStream(x+".html");
BufferedReader br=new BufferedReader(new InputStreamReader(fis,"UTF-8"));
String Line="";
while ((Line = br.readLine()) != null) result+=Line;
br.close();
fis.close();
I use UTF-8 because the file contains also French characters.
What's the problem?
THANK YOU!

Dynamic Text with external .txt files

I need help getting dynamic text to display. I've used the
following tutorials (among others).
http://www.kirupa.com/developer/mx/dynamic_scroller.htm
http://www.kirupa.com/developer/mx/multiple_dynamictext.htm
In Flash 8 on last frame of maintimeline of movie, I have a
layer with a background image, 2 buttons and a dynamic textbox
(made scrollable) with scrollbar component. Textbox is given a var
of "content", and an instance name of "textBox", which is
referenced in scrollbar parameters.
I have created 3 text .txt files, and saved them to same
folder with movie .swf file. Text in files is preceeded by
"content=" on line preceeding text to correspond with var of
dynamic textbox. The files were created in Rich text format on Mac
OSX4.11 and saved with .rtf extension, then file extension was
changed to .txt (wouldn't save as .txt)
I've added the following actionscript to this last frame:
loadText = new LoadVars();
loadText.load("TEXTintro.txt");
//creating the loadVarsText function
loadText.onLoad = function(success){
if (success){
textBox.text = this.content;
else{
trace("Error loading external content");
Buttons have an instance name assigned with the following
actionscript:
on (release) {
loadText = new LoadVars();
loadText.load("TEXT1.txt");
loadText.onLoad = function(success){
if (success){
textBox.text = this.content;
else{
trace("Error loading external content");
When I test movie, I can see buttons on last frame of movie,
but they don't load any text when pressed, and "undefined" text
appears in upper left corner of text box before I press either
button.
I am getting the following Output errors:
**Error** Scene=MoonOfWintertime, layer=TextBox,
frame=2500:Line 1: Statement block must be terminated by '}'
on (release) {
**Error** Scene=MoonOfWintertime, layer=TextBox,
frame=2500:Line 11: Syntax error.
**Error** Scene=MoonOfWintertime, layer=TextBox,
frame=2500:Line 1: Statement block must be terminated by '}'
on (release) {
**Error** Scene=MoonOfWintertime, layer=TextBox,
frame=2500:Line 11: Syntax error.
Total ActionScript Errors: 4 Reported Errors: 4

No more output errors, buttons still not working, but I got
my intro .txt file to load in textbox that loads with frame using
the following code I tried from another tutorial:
loadText = new LoadVars();
loadText.onLoad = function() {
textBox.html=true;
textBox.htmlText = this.textContent;
loadText.load("TEXTintro.txt");
Tried the following code with buttons, but doesn't work.
Other code suggestions?
on (release) {
loadText = new LoadVars();
loadText.onLoad = function() {
loadText.load("TEXT2.txt");
on (release) {
loadText = new LoadVars();
loadText.onLoad = function() {
textBox.html=true;
textBox.htmlText = this.textContent;
loadText.load("TEXT1.txt");
}

Yes thats because its part of larger code.. it is just a method within my code.

Security restrictions , how to read access a txt file supplied in a jar

I had written a simple application which uses file handling to display random line from a file on a swing window
but I do not know how to give my web application permission to access a file
when I set security permission to all, then error says the application cannot load because the code require unrestricted acess to system resources and is unsigned, I don't know how to get that certificate and I am only doing it for learning purposes.
when I remove security permissions then it says

Another few things I noted when I looked at it.
1) There is a stray thread going after the JOptionPane is dismissed. The VM does not end, and the console (if you have it configured to pop-up for JWS apps.) stays on-screen.
2) If all the jokes are prefixed by '* ' I would recommend removing it from every line of the source file and either re-adding it at runtime, or (preferably) not adding it at all (since it is redundant).
3) Reconfigure the app. into a loop, and offer the user a JOptionPane with "Another Joke"/"End" instead of "OK".
4) You can always remove that debugging line I inserted in the code to show the path to the Jar - it was just intended as a 'sanity check' during testing.
5) Why is it Java 1.6+? JOptionPane was introduced in Java 1.2 with the first Swing implementations, and the I/O is compatible with Java 1.1.
>
Thanks again!!!!>Thanks are best expressed (to me) in the notation of a helpful/correct answer (which you have done), and the assignation of (the remaining) dukes*. ;-)
* After all - checks the title - we have gotten entirely around those 'security restrictions' in a sandboxed application. The reason being that File objects are rarely the correct choice, for applets or JWS apps.

How to read data from txt file respectively

Hi,
I am triying to form an equation between two known points. I want to do this with the attached VI, the most critical point is that I will read the x1, y1, x2 and y2 coordinates from the same .txt file. They will be written in a .txt file and I will send them to the appropriate channel (x1, y1, x2 and y2) respectively. How can I get data in a rule from a .txt file?
Could anyone please help me with this issue,
Best regards.

read from txt file.vi ‏8 KB

Dear RavensFan,
Thank you very much for your helps, I am bit new to labview so I usually can not find the appropriate functions easily. And a new problem has rised in my application. I should write the A, B and C numbers in the respective series to the file 2.txt. I am able to write them in a straight forward case but I want to write the next triples (A B C) in the next row. Like this;
A1 B1 C1
A2 B2 C2
A3 B3 C3
So how can I put new line constant and space constant to my VI?
Waiting for your valuable helps,
Best regards,

Why are you creating the score array inside he while loop? What's that for? It looks like it's for all the scores, but if you have 3 lines, then you're creating 3 different scores arrays--one with 1 element, 1 with 2 elements, and 1 with 3 elements.
For all but the last one, you're creating it, populating the last element, then throwing it away.
For the last one, you create it, populate the last element (leaving the first three with their default value of 0) and then that's what gets printed.
When you have this kind of problem, print out a bunch of relevant stuff (and even some stuff that you think is not relevant) at each step of the way, so ou can see what your code is doing. Yout THINK you know what it's doing, but obviously you're mistaken. If you can't figure it out from staring at it, then you'll have to let the code itself tell you what's really going on.
You'll have to create the array before you start the while loop, which means you'll have to know ahead of time how many scores you have, or know some maximum that you could possibly have and make it big enough to hold that many.
Or,instead of an array, you couse use a List, such as java.util.ArrayList.

Reading an external text file in WAR file

Greetings,
I have a question. I have an web application that writes a text message and 0's and 1's based on checkboxes. Then I have a JSP that reads this text file and prints the message and enables/disables links based on the 1's and 0's. I don't have any problems with this when testing from localhost, but when I deploy to a server the application isn't reading the file. The text file and WAR file are in the same folder, same directory. I've tried using both relative and absolute paths to read the file, but to no avail. Is there an easy way to read an external file from a WAR file or is there an easier solution. Thanks
Nick

You should not try to force your text file to live in the same directory as the WAR file. Instead, you should remove that kind of dependency and instead be using something like System.getProperty("java.io.tmpdir") to use the temporary directory to create and delete these files.
Edit: I also bet you don't even need to create & read a file here. You could probably store the information in one of the contexts of the web app, such as in a Session. I'll assume you know what that means.
By creating a file, you are also running the risk of multiple threads (simultaneous users) vying for the same file name, thus walking on each other's data.
