Writing to a File Using JFile Chooser!

pls, iam developing a word processor and i am implementing JFileChooser for my file I/O , the OpenFile program works well, but the save File program is not working well any Way?
Thanks.

if it's not an applet, try:
JFileChooser fc = new JFileChooser();
int result = fc.showSaveDialog( this );
if ( result == JFileChooser.APPROVE_OPTION )
String str1 = fc.getCurrentDirectory() +
System.getProperty("file.separator") + fc.getSelectedFile().getName() ;
File f = new File( str1 );
if ( f.exists() )
int answer = JOptionPane.showConfirmDialog(null,"Do you want to save the changes made before closing","Confirm Dialog",
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE,null);

Writing to a file using log4j

Hi ,
I am facing an issue in rolling out file on an hourly basis. I have a source file , say usagelog_date.log which records logging, then after an hour an hour I have to separate that file , give it a different name say usagelog_date.10.log , I copy the contents of the source file into the rolling file, and make that source file empty. But after making that file empty when I am writing to the file using some threads simultaneously, I get some blank characters first and only after that the logging starts, that increases the file size to a large extent.
My java code which does this separation is as follows.
package com.proquest.services.usage.helper;

How To use JFile Chooser in a Tabbed Pane Dialog

I have created a tabbed pane dialog. In one of the tabs I want to add a JFile Chooser.
How can I approach this problem. also Do I have to use a JDialog with a frame or can I create a JDialog without using a frame and create a instance from the main function.

I have created a tabbed pane dialog. In one of the
tabs I want to add a JFile Chooser. Since JFileChooser is a JComponent you could add it to any Container like any other JComponent.
Maybe you have to do some init by hand which is done normally by the show*() methods of JFileChooser. Taking a look at the source of showDialog() should help.
Hope that helps,
Alex

Reading and Writing large Excel file using JExcel API

hi,
I am using JExcelAPI for reading and writing excel file. My problem is when I read file with 10000 records and 95 columns (file size about 14MB), I got out of memory error and application is crashed. Can anyone tell me is there any way that I can read large file using JExcelAPI throug streams or in any other way. Jakarta POI is also showing this behaviour.
Thanks and advance

Sorry when out of memory error is occurred no stack trace is printed as application is crashed. But I will quote some lines taken from JProfiler where this problem is occurred:
          reader = new FileInputStream(new File(filePath));
          workbook = Workbook.getWorkbook(reader);
          *sheeet = workbook.getSheet(0);* // here out of memory error is occured
           JProfiler tree:
jxl.Workbook.getWorkBook
      jxl.read.biff.File
             jxl.read.biff.CompoundFile.getStream
                   jxl.read.biff.CompoundFile.getBigBlockStream Thanks

Writing data into files using VHDL Textio

Hi
I was trying to write nos. from 1 to 8 into a text file using the below program.
process
type IntegerFileType is file of integer;
file data_out: IntegerFileType ;
variable fstatus: FILE_OPEN_STATUS;
variable coun: natural:= 1;
begin
file_open(fstatus,data_out,"myfile.txt",write_mode);
for i in 1 to 8 loop
write(data_out, coun);
coun := coun + 1;
end loop;
file_close(data_out);
wait; -- an artificial way to stop the process
end process;
But getting the below attached result..
Can you please help me out what could be wrong with the program.
Thanks & regards
Madhur

Do you want the numbers in the file to be human readable ASCII?
Then you'll need to convert your coun to a string.
declare another variable of type line (type access to string).
do a write() to the line, then a writeline() to the file.
natural'image(coun) will convert coun to a string.
Google should help you find example code that will help.

Writing to a file using an applet?

Applets run on restricted security priveelege. Unless you sign your applet, you cant access the files from the applet.

Writing to a file using labview

hello,
so i wrote this vi to write some data to a text file and that part works correctly.
the problem i'm having is that, it doesn't append to the file. so for each data point that it writes it requires a new file.
in otherwords, if i need to write 10 data points the program prompts each time for 10 different file names.
how do i resolve this so that the program will write all the 10 data points to one file, by appending each time.
e.g. data points: 29.5, 34.2, 21.34, 543.2 ... etc
i want something like this:
29.5
34.2
21.34
543.2
etc
thanks

If the path is correctly wired, it should not prompt you for another file. Make sure you wire the path to a shift register so it is available the next time the "write charaters ..." is called.
You can do the "exception" in many ways. Some examples:
--Check if the file exists, and if so, append.
--Use a shift register initialized by "false", then wire it to the append terminal. Feed a "true" to the shift register on the right.
However, you should consider using some of the lower level file I/O and open the file only once, then keep writing data and close it only at the end. The high-level "write characters to file" would need to do a lot of extra work because whenever it is called it opens the file, writes/appends data, then
closes the file again.

Problem writing to excel file using report generation toolkit

hello everyone, i have this report generation toolkit... and i want to output DAQmx Analog I/P data on to an excel sheet. the DAQmx is programmed to collect

can anyone please help me? i am using the MS Office Report Express VI.
Now on LabVIEW 10.0 on Win7

@All, I got rid of the express VI, decided to work on the custom low level VIs instead. however, i have a new problem now...
I have a case statement wherein, the user selects if he wants to start generating a report. once the program enters tat loop, the program speed reduces!
can anyone please tell me why is it happening? i ahve attached the vi... also another question.. in this VI, i am capturing the unwanted data into the graph as I am indexin the graph input. how can i make a logic
that the graph captures the data only when I am switching the CREATE REPORT button (which is in the while loop). is there a way that I can append the data to the graph without creating a new graph every iteration? please let me know
thanks

Writing an XML file using a Servlet

Hello, I'm trying to code a servlet that receives a POST from a HTTP and output its data to a XML file, the problem is that I get the following error:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
XML document must have a top level element. Error processing resource 'http://localhost:8080/XMLSender/xmlsend'.
I don't know what happens, because I'm NOT trying to show the content, just to save it, I post my code here so anyone can help me, please. Thanks in advance.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class xmlsender extends HttpServlet

writer.write("<body>" + cadenabody + "</body>");
writer.write("</root>");
writer.close();
It still do not create my file "salida.xml", still don't know why. Any help is welcome.

Writing to remote files using an applet.

I programmed a basic game as an applet for a web site, but it really needs some kind of high score functionality.
I plan to store the high scores in a file in the server. Reading information from the file is no problem at all, but updating the file with new highscores runs into security problems. Obviously I can't simple use a simle file writer to do that. What is the proper way to do this?
One possibility which came to my mind is to make the applet open a ftp connection to the server and upload the new highscores file to the server. but that would mean hardcoding my password into the applet code.
Please keep in mind using servlets or any other programs running on the server is out of question.
Any help greatly appreciated,thanks in advance.

Why not host this applet on another free server which supports mysql/postgresql/etc and store it in a database? Any hosts/tools needed, just ask - there are several good freeware.

Writing Objects to file using Externalizable

Hi,
I'm trying to write an object to file. My sample code is:
public class Junk implements Externalizable{
private static java.util.Random generator = new java.util.Random();
private int answer;
private double[] numbers;
private String thought;
public Junk(String thought) {
this.thought = thought;
answer = 42;
numbers = new double[3+ generator.nextInt(4)];
for (int i=0; i<numbers.length; i++) {
numbers[i] = generator.nextDouble();
public void writeExternal(ObjectOutput stream) throws java.io.IOException {
stream.writeInt(answer);
stream.writeBytes(thought);
for(int i=0; i< numbers.length; i++) {
stream.writeDouble(numbers);
public void readExternal(ObjectInput stream) throws java.io.IOException {
answer = stream.readInt();
String thought = stream.readUTF();
and the class with main() is:
package MyTest;
import java.io.*;
public class SerializeObjects {
public SerializeObjects() {
public static void main(String args[]) {
Junk obj1 = new Junk("A green twig is easily bent.");
Junk obj2 = new Junk("A little knowledge is a dangerous thing.");
Junk obj3 = new Junk("Flies light on lean horses.");
ObjectOutputStream oOut = null;
FileOutputStream fOut = null;
try {
fOut = new FileOutputStream("E:\\FileTest\\test.bin");
oOut = new ObjectOutputStream(fOut);
obj1.writeExternal(oOut);
//obj2.writeExternal(oOut);
} catch (IOException e) {
e.printStackTrace(System.err);
System.exit(1);
try {
oOut.flush();
oOut.close();
fOut.close();
} catch(IOException e) {
e.printStackTrace(System.err);
System.exit(1);
The output I get in test.bin contains some junk ascii codes. The only item that is written correctly in the file is the string.
Is there anyway I can write correct data into a file?
My output needs to be a readable text format file.
Can anyone help please?

obj1.writeExternal(oOut);This should be
oOut.writeObject(obj1);However,
The output I get in test.bin contains some junk ascii
codes. The only item that is written correctly in the
file is the string.If you don't want 'junk' don't use Externalizable and ObjectOutputStream at all, just use PrintStream/PrintWriter.println().

Writing to a file using url

Hi all,
I have build an applet which I am going to put in a web. Right now I am working locally and I'm able to read file's using this code:
url = new URL("http://localhost/file.txt");
            is = url.openStream();
            BufferedReader bufRdr = new BufferedReader(new InputStreamReader(is));
            while((line = bufRdr.readLine()) != null)
              //do things
            bufRdr.close();
            is.close();
        }Now I would like to be able to write in this file. How could I do it?
Thanks!

Using HTTP to open a local file will only work if you have a web server running locally, and if that server happens to know how to find and deal with that file.
If you want to use that same web server to write files locally, then your local web server will need to have functionality to write files.
So your first issue is dealing with that. How you do this will depend on what web server you're currently running.
Using a web server might not be the best approach, by the way.
