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 do I read from a file and store the information in an array?

Here is my problem:
I am going to have to use a bufferedReader to read a file containing information on 10 vehicles. And after I read that file I want to store the info in Vehicle [] V.
Where should I start?
Thanks
Steve

Thank you for the quick response.
As of right now our code is the same. Now I have to "parse" the information. What exactly do you mean?
My code is as follows:
while((str = br.readLine()) != null)
String[] tokenArray = str.split(" ");
for(int i = 0; i < tokenArray.length; i++)
System.out.print(" Token: " + tokenArray);
System.out.println("\n");
Is that what you mean by parsing?
I am not quite sure what e slpit(" ") is doing. Is there a better way?
And just to make sure I am understanding my own code, I am storing the information from the br in tokenArray. Followed by a series of print statements which output the info.Correct?
Thanks again,
Steve

Scenario to read from txt-file and create a sales order

Hi,

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

Read from txt file and analyse data

hi,
i am having a problem for reading data from a text file and checking whether it is a integer or not.
basically if i have a txt file with the following content:
12 45 345 500 45.67684 33
my output should be:
12 45 345 500 invalid 33
that means if there is a integer number in the file, the integer number will be printed on the screen BUT if there is anything else like a string or a double number, then "invalid" will be printed.
how can i check what kind of datatype it is??
i have the following code to start with:
try
 BufferedReader in = new BufferedReader(new FileReader(FileName));
 String l = in.readLine();
 in.close();
 catch(IOException e)
 System.out.println("IO error");
 System.exit(0);
 }

ok i have tried the following code:
 int index = 0;
 String[] arr = null;
 int nb = 0;
 try
 BufferedReader in = new BufferedReader(new FileReader(nameFile));
 String line = in.readLine();
 arr = line.split(" ");
 for(int i=0; i<arr.length; i++)
 index = i;
 nb = Integer.parseInt(arr);
System.out.print(nb+" ");
in.close();
catch(IOException e)
System.out.println("IO error");
System.exit(0);
catch(NumberFormatException e)
System.out.print("invalid ");
for(int j=index+1; j<arr.length; j++)
nb = Integer.parseInt(arr[j]);
System.out.print(nb+" ");
which works perfectly fine for the following scenario:
txt-file:
12 45 345 500 45.67684 33
output:
12 45 345 500 invalid 33
but what, if I have the following data in my txt file:
12 45 345 500 45.67684 33 23.234 21
then the output should be:
12 45 345 500 invalid 33 invalid 21
how can i solve this???

(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();

Need a VB-Script that read a txt-file and only the lines that are new since last time

Hi,
I need help to write a VB script that read all new lines since the last time.
For example: The script reads the textfile at specific time, then 10 minutes later the script read the file again, and it should now only read the lines that are new since last time. Anyone that has such a script in your scriptingbox?
cheers!

Based on the excellent idea by Pegasus, where is a VBScript solution. I use a separate file to save the last line count read from the file, then each time the file is read I update the line count. Only lines after the last count are output by the program:
Option Explicit
Dim strFile, objFSO, objFile, strCountFile, objCountFile, strLine, lngCount, lngLine
Const ForReading = 1
Const ForWriting = 2
Const OpenAsASCII = 0
Const CreateIfNotExist = True
' Specify input file to be read.
strFile = "c:\Scripts\Example.log"
' Specify file with most recent line count.
strCountFile = "c:\Scripts\Count.txt"
' Open the input file for reading.
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(strFile, ForReading)
' Check if the line count file exists.
If (objFSO.FileExists(strCountFile) = False) Then
    ' Initial count is 0, so all lines are read.
    lngCount = 0
Else
    ' Open the line count file.
    Set objCountFile = objFSO.OpenTextFile(strCountFile, ForReading)
    ' Read the most recent line count.
    Do Until objCountFile.AtEndOfStream
        lngCount = CLng(objCountFile.ReadLine)
    Loop
End If
' Read the input file.
lngLine = 0
Do Until objFile.AtEndOfStream
    ' Count lines.
    lngLine = lngLine + 1
    strLine = objFile.ReadLine
    If (lngLine >= lngCount) Then
        ' Output the line.
        Wscript.Echo strLine
    End If
Loop
' Close all files.
objFile.Close
If (lngCount > 0) Then
    objCountFile.Close
End If
' Ignore last line of the file if it is blank.
If (strLine = "") Then
    lngLine = lngLine - 1
End If
' Save the new line count.
Set objCountFile = objFSO.OpenTextFile(strCountFile, _
    ForWriting, CreateIfNotExist, OpenAsASCII)
objCountFile.WriteLine CStr(lngLine + 1)
objCountFile.Close

Reading from XML file and updating the table ????

Hi
I have package which reads the hier.XML file and does Update inserts into the 5 tables
i have table called MAIN_tbl with the column cur_date.
The package kicks if this cur_date is one day less than the hier.XML file DT.
Currently i m manually checking this date's to make sure the Main_tbl cur_date is n sync with
hier.XML file DT.
for example :- hier.xml file DT is "20091020" then main_table cur_date should be 10/19/2009
in order to kicks of the pakage.
what i m looking to do ??
compare the hier.xml DT with the main_table cur_date,
if cur_date is -1(Preivous day) of hier.xml DT then run hier_pkg(Package)
if not then update main_table cur_date to -1(previous day) of the hier.xml DATE
Then later write the above logic to update the main_table in a procedure, and
then call the package from the procedure.
below are the top few lines of the hier.XML file which is relevant to the one which we are trying to do
<?xml version = '1.0'?>
<HIER_POSTING num ="111" HIER_TYP="CD" DT="20091020" Global="Y">
FYI : The hier.XML file is located in UNIX space.
How do i accomplish this. any idea ????
Thank you so much in advance. For giving a thought on this problem!!!

Any thought on this guys ???
Thanks!!

Reading an XML file and write the contents to another xml file in java

Hi,
I am new to xml parsing.My requirement is that I am getting a message (xml) using ibm MQ in the ByteArrayInputStream format.I have to read this xml message and write to another file.
I am creating a POC for this.
First I used simple reading and writing concept but the output is "java.io.FileInputStream@3e25a5 "
Sample xml file
- <Client>
<ClientId>1234</ClientId>
<ClientName>STechnology</ClientName>
<DTU_ID>567</DTU_ID>

public class ByteArrayInputStreamToXml {
 public static void main(String srg[]) throws IOException{
 InputStream inputStream= new FileInputStream("C:\\soft\\test2\\sample1.xml");
 byte currentXMLBytes[] = inputStream.toString().getBytes();
 ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(currentXMLBytes);
 OutputStream out = new FileOutputStream("C:\\soft\\test\\data.xml");
 int read=0;
 byte[] bytes = new byte[1024];
 while((read = byteArrayInputStream.read(bytes))!= -1){
 out.write(bytes, 0, read);
 out.write( '\n' );
 inputStream.close();
 out.flush();
 out.close();
 System.out.println("New file created!");
Please suggest me how can I use DOM/SAX parser ,I can see several code on net for reading xml file using SAX/DOM parser but writing an xml file after reading it using ByteArrayInputStream I am not getting .A help through some example Link will also be helpful for me.
Thanks

 st.quoteChar('\"'); //set the " quote char
 int i;
 while (st.ttype != StreamTokenizer.TT_EOF) {
 i = st.nextToken();
 if (st.ttype == StreamTokenizer.TT_WORD) {
 if (st.sval.equals("href")) {
 i = st.nextToken(); //the next token (assumed) is the '=' sign
 i = st.nextToken(); //then after it is the href value.
 getURL(st.sval); //retrieve address
 in.close();
 static void getURL(String s) {
 //Check string if it has http:// and truncate if it does
 if (s.indexOf("http://") > -1) {
 s = s.substring(s.indexOf("http://") + 7, s.length());
 //check if not mailto: do not print otherwise
 if (s.indexOf("mailto:") != -1) return;
 //printout anything after http:// and the next '/'
 //if no '/' then print all
 if (s.indexOf('/') > -1) {
 System.out.println(s.substring(0, s.indexOf('/')));
 } else System.out.println(s);
}Hope this helps. I used static methods instead of encapsulating everyting into a class.

How to read from excel file and write it using implicit jsp out object

our code is as below:Please give us proper solution.
we are reading from Excel file and writing in dynamicaly generated Excel file.it is writing but not as original excel sheet.we are using response.setContentType and response.setHeader for generating pop up for saveing the original file in to dynamically generated Excel file.
<%@ page contentType="application/vnd.ms-excel" %>
<%
 //String dLoadFile = (String)request.getParameter("jspname1");
 String dLoadFile = "c:/purge_trns_nav.xls" ;
 File f = new File(dLoadFile);
 //set the content type(can be excel/word/powerpoint etc..)
 response.setContentType ("application/msexcel");
 //get the file name
 String name = f.getName().substring(f.getName().lastIndexOf("/") + 1,f.getName().length());
 //set the header and also the Name by which user will be prompted to save
 response.setHeader ("Content-Disposition", "attachment; filename="+name);
 //OPen an input stream to the file and post the file contents thru the
 //servlet output stream to the client m/c
 FileInputStream in = new FileInputStream(f);
 //ServletOutputStream outs = response.getOutputStream();
 int bit = 10;
 int i = 0;
 try {
 while (bit >= 0) {
 bit = in.read();
 out.write(bit) ;
} catch (IOException ioe) { ioe.printStackTrace(System.out); }
 out.flush();
out.close();
in.close();
%>

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
 * @param args [0] = source filename
 * args [1] = destination filename
 public static void main(String[] args) throws Exception {
 if (args.length != 2) {
 System.err.println ("Syntax: java -cp . Kopy source destination");
 System.exit(1);
 File in = new File(args[0]);
 long fileLength = in.length();
 long t = System.currentTimeMillis();
 FileInputStream fis = new FileInputStream (in);
 FileOutputStream fos = new FileOutputStream (args[1]);
 FileChannel fci = fis.getChannel();
 FileChannel fco = fos.getChannel();
 fco.transferFrom(fci, 0, fileLength);
 fis.close();
 fos.close();
 t = System.currentTimeMillis() - t;
 NumberFormat nf = new DecimalFormat("#,##0.00");
 System.out.print (nf.format(fileLength/1024.0) + "kB copied");
 if (t > 0) {
 System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");
}

Can a servlet read a jsp file and display its contents?

Hi,
I would like to know if Servlets can read a Jsp file and display its contents.. Right now for our website, I am using a html file to be displayed after a successful post operation through the Servlets...
-Thanks!

I posted this in another thread.
Here's some code that reads using a URL. This doesn't work with JSPs as the server executes JSP when it connects but it's useful for other file types. Note that the filename is a URI</h1>This is <code>show.jsp</code></h1>
<hr>
<%! String file = null; %>
<%! java.io.InputStream is = null; %>
<%
file = request.getParameterValues("filename")[0];
try {
is = (new java.net.URL(file)).openStream();
} catch (java.io.IOException ioe) { out.write(file + " not found! "); }
java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(is));
String line = "";
%>
<pre>
<%
while((line = in.readLine()) != null) {
%>
<%=line%>
<%
%>
</pre>

How i can to create a vi, which read from configuration file and i could modify this indicator and save the config data??

Hi guys,
I have in my application a subvi which i use to save the configuration of application. I create one file with the last saved configuration, and i would like to open this values and that i could to modify this indicator value, but i cant since to modify i need 'numeric control' and to read the data from file i need 'numeric indicator '...
I thought, use a numeric control and use the values from file to the default values, but i didnt get to find the property node to adjust it. is it possible? or any different way to get it....??
Also, i attached the capture file.. i would like the program DOESNT SHOW the question of
replace the file!!. i would like directly replace the file when i push save.
Thanks, i attached the vi.

Hi Dennis,
Your 'write to sreadshhet mod' suprime the dialog of replace file or not!, i want when i push save, it show the dialog input name of file and show the default sim000 but when i push this sim000 and this file already exist, then show the dialog to replace or not, if i replace Ok not problem, but when i push cancel replace it shows error eof!!!.
Your file, only remove this dialog and only replace the file directly.
i put the capture, when i choose the file to save and the program say to me this file exist and it give me the option of replace or not,i want when i push cancel replace it continues running without get error.
is it possible?.
Thanks.
Regards, Fonsi.
