Read lines from text-file in specified [ITEM]

Hello,
are there any functions integrated in Labview to read a text-file which looks like this:
[ITEM-NAME_01]
parameter1 = here
parameter2 = 1123
parameter3 = a453
[ITEM-NAME_02]
parameter4 = here
parameter5 = 1123
parameter6 = a453
Can this be done easy, or do i have to manually search the file for the "["-character ?
At the end i want a VI where i pass the file-name and the item-name as input, and as output i want one array with the parameter-names and the other array with the values.
How can this be done?
Thanks for your help

Hi OnlyOne,
you are talking about Configuration files?
Look in the file palette, sub-palette "configuration files". It's all in there!

Read lines from a file

With "ApartmentFileHandler" I can write Apartment-objects to a file and read them from a file.
To write I loop through each room in the apartment and write its size
and type. I put 1 Room per line.
To read I read each line of the file and recreate the room stored
there. When there are no lines left in the file I pass the Rooms from
the file to the Apartment constructor and return the new Apartment.
Only one Apartment is stored in each file. (Apartment doesn?t implement
Serializable, so I cant write straight Apartment-objects to a file.)
So in the file, there are stored one "Room" per line: String type,
double size
QUESTION: How am I able to read all lines: first line first -> make a new room of
it, and store to a roomArray? Then second -> do same as I did to the
first.
Now my read()-method doesn't read all lines. How to change it to read next line?
Thanks in advance.

Hi,
I recommend using java.io.BufferedReader in conjunction with java.io.FileReader:
BufferedReader reader=new BufferedReader(new FileReader(filepath));
java.io.BufferedReader provides the method public java.lang.String readLine() throws java.io.IOException which lets you read a complete line from the underlying java.io.Reader object. Furthermore, BufferedReader will - as the name implies - buffer your IO-operations which will help you improve the program's performance. In order to read all the lines contained in a text file you might want to apply a loop:
String line;
while((line=reader.readLine())!=null && line.length()!=0){
//process data in string line (parse into string and double)
Of course, everything must be contained within a try-catch-block in order to be able to handle upcoming IOException objects.

Michael

First of all, when posting code, put it between two tags.
Second of all, the pipe is a special character in regex, so you need to escape it as
.split("\ \|");
Erh. So 2 backslashes before the pipe character. Stupid forum won't post it.

public void NewTail( String i, String f, String l, String m, String p)
if (stu == null)
stu = new ListNode(i, f, l, m, p, null);
else
ListNode temp = stu;
while ( temp.next != null)
temp = temp.next;
temp.next = new ListNode(i, f, l, m, p, null);
}(/code)

then from the class i use
record st = new record();
         FileReader file = new FileReader( "student.txt");
         BufferedReader inputFile = new BufferedReader( file);
         int ID = new Integer( inputFile.readLine()).intValue();
         while( ID > 0)
            String first = inputFile.readLine();
            String last = inputFile.readLine();

Read pixel from text file

Hi, is it possible to retrieve an image just by reading some parameters or its pixel from a text file? If yes, could anyone give me some ideas on how to do that? How do you also retrieve a specific line or value from a text file?
Thanks.

Hi Fred,
it seems you started a new thread for that very same topic - again...
Why can't you keep things in one place? Why do we have to hop between several threads of yours to get all relevant information?
"if I want to read line 13 of my text file"
Same question as in the other thread: Where do you start to count? 0 or 1?
Have you tried to wire a "13" to the ReadLine function?

Read char from text file

I am trying to read in questions, possible answers and the correct answer from a text file.
The text file looks like this
1. what is blah blah blah?
a. something
b. something else
c. none of the above
b
where the last line of the file is a character which is the correct answer.
I can read all these in as a string but I have to read the last line in as a character .
can you please help.

I'm not sure if this is what you need but, take a look:
import java.io.*;
public class questions
public static void main(String[] args)
try
Question a=new Question();
ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream(new File("answers.txt")));
out.writeObject(a);
ObjectInputStream in=new ObjectInputStream(new FileInputStream(new File("answers.txt")));
Question b=(Question)in.readObject();
char answer=b.getAnswer();
System.out.println(answer);
catch(IOException e)
System.out.println(e);
catch(ClassNotFoundException e)
System.out.println(e);
class Question implements Serializable
String q;
String a1;
String a2;
String a3;
char c;
public Question()
q=new String("The Question");
a1=new String("1st possible choise");
a2=new String("2st possible choise");
a3=new String("3st possible choise");
c='c';
public void setQuestion(String que)
q=que;
public void setAnswer1(String an1)
a1=an1;
public void setAnswer2(String an2)
a2=an2;
public void setAnswer3(String an3)
a3=an3;
public void setAnswer(char an)
c=an;
public char getAnswer()
return c;
Ofcource all methods in Question class should be adapted to the needs of your program.

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.
profravi

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.

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.

Read value from text file to JTextField

Hi,
I think this is the right place to post this. Although maybe it is not it could be classed as I/O issues?
I have a JFrame with a JTextField which requires the user to enter a value. When they click a JButton "OK". It writes the value to a text file and closes the frame using FileWriter. If they click clear button it writes the value "" to the file. What I want to do is when the frame opens it reads the value from the text file. I have been trying to use FileReader but have not been able to write the code correctly. Any help would be greatly appreciated.
Thanks

File f = yourfile;
BufferedReader br = new BufferedReader(new FileReader(f));
String value = br.readLine();Alex.

Read url from text file

I am new to Adobe Air. I was able to load a web browser as an Air app with the following line:
<mx:HTML id="myBrowser" width="100%" height="100%" location="http://www.google.com"/>
My question is this: is it possible to add a text file to the project (to be stored locally) that can be read by the application so that the location attribute (URL) can be dynamically populated?
I want the user to be able to change the starting URL by manually editing this text file.
Any help I can get is appreciated!
Note: I am aware that a URL bar can simply be added to the app, but that is really not the solution that I'm looking for. I don't want the user to be able to change the url using the GUI.

Great, thank you for your response!
Could you give me a sugestion on how to aproch the code. Specifically how to read the file itself. Would it require a specific format?
Thanks you.

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

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

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.

How to write a function read line from a file in FDK?

Hello,
I want to write a function that can read a file in line by line in FDK. How do I write it. If FDK could not. Is there any the way? Please help.
Thank you,
Thai Nguyen

Thai,
You can use the "channel" functions for this. I'm far from an expert on channel programming but I've read files line-by-line successfully by going one character at a time, looking for a carriage return.
You can open up the file channel with something like:
ChannelT chan;
FilePathT *path;
UCharT ptr[1];
IntT numRead;
path = F_PathNameToFilePath("C:\\temp\\mydoc.txt", NULL, FDefaultPath);
if((chan = F_ChannelOpen(path,"r")) == NULL)
return;
//read the first character
numRead = F_ChannelRead(ptr, sizeof(UCharT), 1, chan);
...then you can call F_ChannelRead iteratively to build the string in a buffer, looking for a carriage return (ASCII 13) and stopping there. (that is, ptr[0] == 13).
There might be a better way. This is just the way I've gotten it to work. It probably is not a good method for unicode files.
