Read data from text file one by one using for loop

Dear Forum
I want to read data of single colum of text file inside the for loop one by one(for each iteration value must be replaced by another value of text file).This value is used by a formula inside for loop. also after completion of iterations the values must be plotted on xy graph. How to do it.? please help me.

It's not very efficient to read a file line by line. Much simpler to read it all at once and then auto-index the results inside a for loop. The image below shows a generic solution to your problem. This assumes that the data in the file is in a single column.
I would also recomend checking ou the learning LabVIEW resources here.
I would aslos suggest that since this type of question is not specific to either NI-Elvis or the LabVIEW SE, you should post similar questions to the LabVIEW board. If you have problems, attaching a sample of the text file would help.

Import data from text file to a table using t-sql

Hi,
I am trying to import data from a text file to a table using the below query but it is returning an error.

Charting data from text file in LabVIEW 5.1 for Windows

I am having some difficulties trying to figure out how to plot a chart with
data from a file. I would like to be able to read data from a text file
into a chart using LabVIEW 5.1 for Windows. I have looked in the help
within the program and online. I have also looked in the user manual and
the book "LabVIEW for Everyone". Could you please give me specific
instructions on how I would construct the program to be able to do this.
Thank you.

Hi Ellie,
It depends on how data is stored in that txt file. Usually you load the data into an array either using or , the array if necessary and send it to the graph indicator in required form. If you want a more detailed answer, send me a sample data file ([email protected]).

Student in distress: Read data from text file to fill a JTable

I'm already late 2 weeks for my project and I still can't figure this out :(
The project is made of 3 classes; the main one is Viewer.java; it creates the interface, Menu.java that manages the menu and the methods related to it and finally JTableData.java that extends JTable ( This is the part that I don't really understand)
In the class MENU.JAVA I wrote the method jMenuOpen_actionPerformed(...) for the button OUVRIR (Open) that let's me select the file to read, then puts the content in a 2D table. Here' s my problem: I have to somehow update the content of the table created in VIEWER.JAVA with the content read from the file (cvs file delimited by ";") using a JTableData object (?)

Hi, Salut
you should use JTable's DataModel to update your table.
data[row][column] = currentLineTokens.nextToken();
jTableInfo.getModel().setValueAt(data[row][column], row, column);
jTableInfo.repaint();BEWARE CSV files and StringTokenizer, i've had problems with it (for example ;;Test; is not tokenized "", "", "Test")
StringTokenizer ignores separator when in first position, and ignores double separators. I use this piece of code before tokenize a String :
private static char _separator = ';';
private static String checkCsvString(String s) {
         * V�rification du s�parateur inital, perdu par le StringTokenizer et
         * pourtant bien important
        if (s.startsWith("" + _separator)) {
            s = " " + s;
         * V�rification des doubles s�parateurs, perdus par le StringTokenizer
        int index;
        while ((index = s.indexOf("" + _separator + _separator)) >= 0) {
            s = s.substring(0, index) + _separator + " " + _separator + s.substring(index + 2);
        return s;
    }hope it helps

Read data from text file and displaying on Webdynpro

Hi all,
I need some help. I have a text file with set of name, phonenumbers . I want to know how to display the data using Webdynpro. Could some one help me. help is appreciated and I promise to award points for right answer.
Thank you
Maruti

Hi Maruti,
just open the file and loop on the rows, here an example::
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
FileReader f = new FileReader("c:
FileName.ext");
while ((s = in.readLine()) != null)
//Here you can put the line into a WD context structure, i.e:
wdContext.currentContoEconomicoFormElement().setField(s);
}catch (Exception e) {.....}
in.close();
f.close();
For any others questions, please, let me know.

Applescript to read data from text file

Hello all, I am writing an Applescript to read a file and put that file's contents into a variable. However, when I use the applescript command "read", I get the error:
The text file reads "4.65". I need to extract that number to show up in a dialog box. This is the code I have so far.
set milefile to ("Macintosh HD:Users:RyanSiebecker:Documents:Scripts:Source-Files:Running-Files:milefile.tx t")
set theFileContents to (read file milefile)
I am stuck and I cannot find any other way to do this.
As always, any help is appreciated.
Thanks, Ryan

Have you noticed that your file name's extension (".tx t") has a space in it? Though that mismatch would get a -43 Not Found error, not EOF.
Your code ( with and without the gapped extension) works here.
Maybe the path isn't perfect?
To make a perfect path easily, start with this:
set milefile to POSIX file ("") -- note the null string ("")
Then arrange your windows so that you can drag the icon representing your file from wherever it is in the Finder's world into your AppleScript Editor's window, and carefully drop it right between the ""s.
If you miss, don't worry. It'll be selected, so just Cut and then Paste it between the ""s. You'll get a perfect path, only with slashes instead of colons. The "POSIX file" specifier converts it to "colon notation", still perfectly.

There was also a question on this over at AskTom
(asktom.oracle.com) about a week ago complete with sample code.
The pointer to the sample code is here:

Admittedly it's about Win95, but the principles should apply.

Read data from Excel file and diaplay in Webdynpro

Hi all,
I need some help. I have a Excel file with set of name, phonenumbers . I want to know how to display the data using Webdynpro. Could some one help me. help is appreciated and I promise to award points for right answer.
Thank you
Maruti

Hi
i can explain you to read data from Excel file
First You have to download the jxl.jar file. You can get this file from the Below site
<a href="http://www.andykhan.com/jexcelapi/download.html">jexcelapi jar</a>
It will be in Compressed Fromat So Unzip it to get the Contents
After Unzipping The File You will get a Folder (jexcelapi/jxl.jar)
Now in NWDS open web dynpro explorer, Right Click Your Project, a popup menu will appear and in that click Properties
You will get window displaying your Project Properties
On Left Side of the window You Will Find "Java Build Path"
Click That "Java Build Path" and you will get 4 Tabs Showing ( Source,Projects,Libraries,Order and Export)
Click Libraries Tab
You will find options many options buttons
In that click the Button "Add External Jars"
You will get Window in order to fecth the jxl.jar file from the location you had stored
After selecting the jxl.jar i will get displayed and click ok
Now Open Navigator
Open Your Project
You will find Lib folder
Copy the jxl.jar to that lib folder
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
You have Upload the Excel file from the Server Using the File Upload UI Element
This Coding will extract 3 columns from the Xls File

Reading data from flat file Using TEXT_IO

Dear Gurus
I already posted this question but this time i need some other changes .....Sorry for that ..
I am using 10G forms and using TEXT_IO for reading data from flat file ..
My data is like this :-
0|BP-V1|20100928|01|1|2430962.89|27|2430962.89|MUR|20100928120106
9|2430962.89|000111111111|
1|61304.88|000014104113|

1|38475.65|000023640081|
1|49749.34|000032133154|
1|35572.46|000033093377|
1|246671.01|000042148111|
Here each column is separated by | . I want to read all the columns and want to do some validation .
How can i do ?
Initially my requirement was to read only 2 or 3 columns so i did like this ...

But now how can i do ? Shall i use like this select Statement for all the columns ?

Sorry for that ..
As per our requirement ...
I need to read the flat file and it looks like like this .

I have to check the file :-
Validation are 1st line should start from 0 else it should raise an error and insert that error into one table .
The for 2nd line also same thing ..it should start from 9 else it should raise an error and insert that error into one table .
Then the 3rd line should start from 1 else it should raise an error and insert that error into one table .
After that i have to do a validation like i will read the 1st line 2nd column .. It should be like this BP-V1 else raise an error and insert that error to a table . Then i will check the 3rd column which is 20100928 , it should be YYYYMMDD format else same thing ERROR.
Then like this for all columns i have different validation .......
Then it will check for the 2nd line 3rd column . this is an account no .1st i will check it should be 12 char else ERROR .Then I will check that what user has imputed in the form.Like for example User putted 111111111 then i will check with this 000111111111 which is there in the 2nd line . I have to add 000 before that Account no which user imputed .
Then the lines which is starting from 1 , i have to take all the 2nd column for all the lines which is starting from 1 and i have to do a sum . After that i have to compare that sum with the value in the 1st lines ( Starting from 0) 6th column . It should be same else ERROR ...
Then same way i have to count all the lines which is starting from 1 . Then i have to compare with the 7th column of 1st line . It should be same . Here in this file it should be 9.

To read data from exel file into sap

hi all,
How to read data from exel file into the internal table in abap?

ENDIF.
for HAS_FIELD_SEPARATOR Use
'X': Fields are separated by tabs.
SPACE: Fields are not separated by tabs. In this case, the table must contain only one column or all columns must be contained in the file in their entire length.
Hope it helps...

Dynamic Internal Table for reading data from external file

Hello All,
The task was to create a internal table with dynamic columns,
Actually this is my first task in the WebAS 6.20, my program is based on input file provided by user with certain effort. this file can have different effort for a one yr to five year frame..
I needed to read the raw data from file, based on months create a internal table to hold the data, after this i need to validate the data...
I have browsed thru dynamic internal table topic, but couldn't find any dynamic appending structure, the dynamic structure would contains 12 month fileds.
can any one help me in getting my task completed..
Thanks
Kumar

Hi,
I see that you posted the same question a couple of days ago at Dynamic Internal Table for reading data from external file Didn't Charles's response address your problem?

Read data from xml files and populate internal table

Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...

<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
 xmldata type xstring .
DATA: mr TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
 IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
 SOURCE XML xmldata
 RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
 WRITE: / struct_accontextdir-context_id,
 struct_accontextdir-context_name,
 struct_accontextdir-context_type.
 NEW-LINE.
 ENDLOOP.</pre>
 
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
 IMPORTING e_content = xmldata ).
 Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
 SOURCE XML xmldata
 RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
 CALL TRANSFORMATION id
 SOURCE shiv = t_internal_tab
 RESULT XML xml.
 CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
 
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

Read lines from text file to java prog

how can I read lines from input file to java prog ?
I need to read from input text file, line after line
10x !

If you search in THIS forum with e.g. read lines from file, you will find answers like this one:
Hi ! This is the answer for your query. This program prints as the output itself reading line by line.......
import java.io.*;
public class readfromfile
public static void main(String a[])
if you search in THIS forum, with e.g. read lines from text file
try{
BufferedReader br = new BufferedReader(new FileReader(new File("readfromfile.java")));
while(br.readLine() != null)
System.out.println(" line read :"+br.readLine());
}catch(Exception e)
e.printStackTrace();
}

Cant get data from text file to print into Jtable

Instead of doing JDBC i am using text file as database. I cant get data from text file to print into JTable when i click find button. Goal is to find a record and print that record only, but for now i am trying to print all the records. Once i get that i will change my code to search desired record and print it. when i click the find button nothing happens. Can you please take a look at my code, dbTest() method. thanks.
void dbTest() {
DataInputStream dis = null;
String dbRecord = null;
String hold;
try {
File f = new File("customer.txt");
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
Vector dataVector = new Vector();
Vector headVector = new Vector(2);
Vector row = new Vector();
// read the record of the text database
while ( (dbRecord = dis.readLine()) != null) {
StringTokenizer st = new StringTokenizer(dbRecord, ",");
while (st.hasMoreTokens()) {
row.addElement(st.nextToken());
System.out.println("Inside nested loop: " + row);
System.out.println("inside loop: " + row);
dataVector.addElement(row);
System.out.println("outside loop: " + row);
headVector.addElement("Title");
headVector.addElement("Type");
dataTable = new JTable(dataVector, headVector);
dataTableScrollPane.setViewportView(dataTable);
} catch (IOException e) {
// catch io errors from FileInputStream or readLine()
System.out.println("Uh oh, got an IOException error!" + e.getMessage());
} finally {
// if the file opened okay, make sure we close it
if (dis != null) {
try {
dis.close();
} catch (IOException ioe) {
} // end if
} // end finally
} // end dbTest

Here's a thread that loads a text file into a JTable:
http://forum.java.sun.com/thread.jsp?forum=57&thread=315172
And my reply in this thread shows how you can use a text file as a simple database:
