You need to give more detailed information about the UI and how you wired it up.
Bay the way, why do you use en execute command line to do this? You can manipulate a jar (or zip) directly.

How to write text file in Shockwave?

Does anybody know how to write text file in Shockwave to
user's disk?
Thanks in advance.

Those Xtras can wreak to much havoc when used with the wrong
intent.
What you can do is write with setpref and store a list of
saves and the
saves itself seperatly. Then you'd have to build your own
save/open
dialog to let the user:
* pick a previously saved file to load or overwrite
* have the user type the name of a new file to save.
Only thing that remains is that the user cannot decide where
the files
are saved.

Hi,
here is a commented program stanza
var v = this.getField("myTextField").value;
// Get the contents of the file attachment with the name "MyNotes.txt"
var oFile = this.getDataObjectContents("MyNotes.txt");
// Convert the returned stream to a string
var cFile = util.stringFromStream(oFile, "utf-8");
// Append new data at the end of the string
cFile += "\r\n" + v;
// Convert back to a stream
oFile = util.streamFromString( cFile, "utf-8");
// Overwrite the old attachment
this.setDataObjectContents("MyNotes.txt", oFile);

Read/Write text files in LabVIEW

We have developed an instrument control and data acquisition system for a mass spectrometer using LabVIEW FPGA. Currently we have 6 counters on the FPGA, counting for 1 second intervals and transferring data to the host using a FIFO.
The data, as a local variable, is used in several different parallel loops on the host. One of these is coded to write the data to a text file. Unfortunately everything we have tried has failed. It is proving impossible using either the write to file VI provided with labVIEW, or to use the Open file, write and close file utilities. Each attempt has failed. Yet when running a dummy code we can write to files. The dummy code consists of 6 random number generators running in one loop and the write to file VI in a second loop. The random numbers are transferred across the loops as local variables.
Can anyone offer any advice as to what we might be doing wrong. We're beginning to feel as though we are banging our heads against a brick wall and getting very frustrated.
Many thanks in advance for any suggestions.

Hi Paul,
you neither say, what is failing nor do you show any code... How should we help then?
"impossible using ... the write to file VI"
Well, usually they work just fine.
"Each attempt has failed."
In which way? Error number given? Did you use the debuging tools, like probing, breakpoints and highlighting?
"as local variables."
It seems you're not properly do program "real" LabVIEW code

Read and Write Text Files

How do I add text from an input text box from flash to a text
(.doc) file when you press an OK button. I want to make the button
have an:
on (release) {
//script
Lets say the URL is "/scene_detail.doc". I can also use .txt
files, but I'd much prefer someone to tell me how to do this with
DOC files. Thanks in Advanced!

Flash cannot write files. You must have some sort of
serverside script do
this, something like ColdFusion, php, asp, perl or cgi.
There is a sample here that writes to an XML file with php:
http://www.kirupa.com/web/xml_guestbook.htm
Here is one that writes to a text file with perl:

Hi how to write text file continuosly

hi i know how to write a text file but if i write something and close the
whole program, then when i open the program and do the samething,
i wanna write something contiguosly, write the next line of the very last saved line..
but..i tried couple of times,but the written sentence just overlapped,,,and
can't write continuously,,,
how to solve it............

Are you saying you want to create a file the first time you run a program, and append to the file the second time? If so, check the constructors for the class you are using to write the file. There should be one that takes a boolean flag telling it you want to append instead of overwrite. Set the flag to true.
For example:
http://java.sun.com/j2se/1.5.0/docs/api/java/io/FileWriter.html#FileWriter(java.lang.String, boolean)FileWriter(String fileName, boolean append)
Constructs a FileWriter object given a file name with a boolean indicating whether or not to append the data written.

How to read\write text file into oracle database.

Hello,
I am having text file called getInfo in c:\temp folder. I would like to populate data from text file to data base. How to proceed. Could anybody help me out.
Thanks,
Shailu

Here is a web page with easy to follow instructions regarding external files: http://www.adp-gmbh.ch/ora/misc/ext_table.html.
Now I understand what all the excitement is over external tables.
"External tables can read flat files (that follow some rules) as though they were ordinary (although read-only) Oracle tables. Therefore, it is convenient to use external tables to load flat files into the DB." -from the above link.

How to read/write text file to db2 by using java code

Hai
I created the table to insert a clob data as follows
db2 => create table ctest(datas clob(65536))
DB20000I The SQL command completed successfully.
db2 => describe table ctest
Column Type Type
name schema name Length Scale Nulls
DATAS SYSIBM CLOB 65536 0 Yes
1 record(s) selected.
I tried the following java code to insert a clob data.
public static synchronized Connection getConnection() throws Exception {
Connection m_connectionDatabase = null;
try {
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
// Get the connection to the database.
m_connectionDatabase = DriverManager.getConnection(
"jdbc b2 ps","","");
}catch (Exception e) {
throw new Exception("Failed to connect to the database. ", e);
return m_connectionDatabase;
public static void main(String a[]) {
File file = new File("d:\\a.txt");
InputStream fis = new FileInputStream(file);
Connection con = getConnection();
PreparedStatement pstmt = con.prepareStatement("insert into ctest values(?)");
//try 1
pstmt.setAsciiStream(1,fis,(int)file.length());
// try 2
pstmt.setCharacterStream(1,fis,(int)(file.length()));
// try 3
pstmt.setBinaryStream(1,fis,(int)(file.length()));
// try 4
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setBytes(1, b);
// try 5
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setString(1, new String(b));
pstmt.executeUpdate();
pstmt.close();
fis.close();
Result:
If the file size is less than 32kb, it inserted successfully.
but if more than 32kb, it throws follwing exception
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0352N An unsupported SQLTYPE was encountered in position "1" of the input list (SQLDA). SQLSTATE=56084

Read a large size text file

how can i read a large size text file in multiple parts without lossin any data ?
Ben

Why are you afraid of losing data? There's no reason that you would lose data if you are reading a large text file.
You should use the various Reader and Writer classes in package java.io to read and write text files. Here's an example of how you can read a text file line by line:
BufferedReader r = new BufferedReader(new FileReader("myfile.txt));
int lineno = 1;
String line;
while ((line = r.readLine()) != null) {
System.out.printf("%d: %s%n", i, line);
i++;
r.close();

Overwriting Text Files?

I've got a program that writes text files ... cool. Up until now, I've been tagging the text file names with a time stamp so they don't overwrite each other between program runs. Now I'd like to (under certain criteria) actually overwrite some of these files.I know that I can overwrite the files simply by giving them the same name...(see implementation notes) ...but do I need to be concerned about the old file? ...like causing fragments or whatever?... I have a hard time imagineing that the code that writes (or in this case overwrites) the files will handle that.
Implementation notes: I basically, use a BufferedWriter chained to a FileWriter ... then I close it when Im finished.
BufferedWriter bw = new BufferedWriter(new FileWriter(myFileName));
bw.write("stuff");
bw.newLine();
bw.flush();
bw.close();

...but do I need to be concerned about the old file?No.
...like causing fragments or whatever?Yes, it probably will. No way around it.

Load text file into applet

hi,
I am new to java and really need some help.
I want to load / read a text file in my applet line by line
the text file looks like:
P,161,127,3,ff6599c2
P,161,127,3,ff6599c2
P,161,128,3,ff6599c2
P,161,129,3,ff6599c2
etc.
the code I tied and did not work looks like:
class read
     public void main( String[] args)
          int i;
          if (args.length < 1)
               System.out.println("Please enter file: read<datei>");
               System.exit(-1);
          try
               BufferedReader in =new BufferedReader(new FileReader( args[0]));
               String line = new String();
               while((line=in.readLine())!=null)
                    System.out.println( line );
          catch(IOException e2)
has anybody an idea how to do it?
Thanks a lot
Silke

<PRE>
First off you need to create a class which extends the
Applet class. The applet class does not have the
method "public static void main(String args[])". Instead it has a method "init()". In the "init" method you should
write the code that you would write in "main". The "init"
method is only executed once. When the applet is first downloaded. Here is a sample code, but there is one other factor to note. Applets have trouble accessing
files on computers. This goes above and beyond the
applet sandbox which locks up an applet. In my experiences I have only managed to read and write text
files to the desktop through applets. The program can
be used by entering the file name in the text field
at the top of the applet and then clicking the "Read File"
button at the bottom of the applet. This code segment is untested and it has been some time since I have done
applet programming but it should work. You may have to
edit the security policy file(security.policy) to grant permission to your codebase before this functions properly because it involves reading from the file system. The grant should look something like this(if you are running under unix/linux I believe you would substitute"file:\\\" with "file:/"):
grant codeBase "file:\\\<Directory Path that contains
the MyApplet class" {
java.io.FilePermission "read", "*"
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
<Applet Code="MyApplet" width="300", height="300">
</Applet>
class MyApplet extends Applet
implements ActionListener {
TextArea ta=new TextArea();
Button readFB=new Button("Read File");
TextField tf=new TextField();
public void init() {
setLayout(new BorderLayout());
Panel tempPan=new Panel();
tempPan.setLayout(new BorderLayout());
tempPan.add("West", new Label("File Name:"));
tempPan.add("Center", tf);
add("North", tempPan);
add("Center", ta);
add("South", readFB);
readFB.addActionListener(this);
setSize(300, 300);
show();
public void actionPerformed(ActionEvent ae) {
String action=ae.getActionCommand();
if(action.equals("Read File")) {
String strFileName=tf.getText();
BufferedReader br=new BufferedReader(new FileReader(new File(strFileName)));
ta.setText("");
String nextLine="";
while((nextLine=br.readLine())!=null) {
ta.append(nextLine+"\n");
br.close();
ps: be careful when modifying security policy file.
It will affect all applet code that is loaded from the
codeBase specified. If no codeBase is specified it
will apply to all codeBases leaving you vulnerable
to malicious applets. Good luck.

HOW TO WRITE AND READ FROM A TEXT FILE???

How can I read from a text file and then display the contents in a JTextArea??????
Also how can I write the contents of a JTextArea to a text file.
Extra Question::::::: Is it possible to write records to a text file. If you have not idea what I am talking about then ignore it.
Manny thanks,
your help is much appreciated though you don't know it!

Do 3 things.
-- Look through the API at the java.io package.
-- Search previous posts for "read write from text file"
-- Search java.sun.com for information on the java.io package.
That should clear just about everything up. If you have more specific problems, feel free to come back and post them.

How do I read from a text file that is longer than 65536 lines and write the data to an Excel spreadsheet and have the data write to a new column once the 65536 cells are filled in a column?

I have data that is in basic generic text file format that needs to be converted into Excel spreadsheet format. The data is much longer than 65536 lines, and in my code I haven't been able to figure out how to carry over the data into the next column. Currently the conversion is done manually and generates an Excel file that has a total of 30-40 full columns of data. Any suggestions would be greatly appreciated.
Thanks,
Darrick
Solved!
Go to Solution.

No need to use nested For loops. No need for any loop anyway. You just have to use a reshape array function. The picture below shows how to proceed.
However, there may be an issue if your element number is not a multiple of the number of columns : zero value elements will be added at the end of the last column in the generated 2D array. Now the issue depends on the way you intend store the data in the Excel spreadsheet : you could convert the data as strings, replace the last zero values with empty strings, and write the whole 2D array to a file (with the .xls extension ) using the write to spreadsheet function. Only one (minimal) problem : define the number of decimal digits to be used;
or you could write the numeric array directly to a true Excel spreadsheet, using either the NI report generation tools or ActiveX commands, then replace the last elements with empty strings.
We need more input from you to decide how to solve these last questions.
