Read a non english word from text file

While Reading thai charater from text file which was sent by QAD(a different application),
We are reading 60 char using substr() function.
If the data is English word it reads correctly with 60 char.
But if it is in thai characters it returns more than 60 char.
In oracle all NLS Char set has been already set.
Can anyone help in this issue
thanks in advance

Maybe you should use SUBSTRC, SUBSTR2 or SUBSTR4 depending on the character set of your database. See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96540/functions119a.htm#87068

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.

Reading first word from text file

Hello all,
I created a program which I can type in a line and store it into a file. What I need my next program to do is read and display just the first word from each line on the text file.
Here is what I have:
import java.io.*;
public class ReadFromFile
public static void main (String args[])
     FileInputStream firstWord;
          try
              // Open an input stream
              firstWord = new FileInputStream ("FileofWords.txt");
              // Read a line of text
              System.out.println( new DataInputStream(firstWord).readLine() );
              // Close our input stream
              firstWord.close();
               System.err.println ("Unable to read from file");
               System.exit(-1);
}

what i would like is my program to get the first word of every line and put it in my array.
This is what i have attempted.
import java.io.*;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
public class testing {
     String[] tmp = new String [2];
     String str;
     public void programTest()
          try
                         BufferedReader in2 = new BufferedReader(new FileReader("eventLog.log"));
                         while ((str = in2.readLine()) != null)
                              tmp = str.split(" ");
                              System.out.println(tmp[0]);
                    catch(IOException e)
                         System.out.println("cannot read file");
public static void main(String[] args)
             testing B = new testing();
             B.programTest();
}//end classAny help is most appreciated

Read and average n data from text file

I acquire numeric data from the oscilloscope [reading a waveform] that is stored in one column in a text file.
I need to read in selectable amount of data points to average/plot them.
So basically I wanna have a text file with millions of data points but I wanna plot say only every 1000. data point. I have tried many things I found here on the forum but as I am new to LabView, none of them really worked.
Does anybody have a suggestion.
Thanks.

It should work, however I gave it less than five minutes testing.

Reading a non-english character

Hi, I have a trouble with reading a non-english character from a html page.
I'm taking the word from the html page, and compare it with itself,
like this
string.equals("BİTTİ")
but it returns false.
is it possible to correct this?

specify an encoding for your inputstream reader:
BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream("infilename"), "8859_1")); for example

Power Shell - Read from text file

Looking to see how to output select data from c:\test\test.txt file to c:\test\output.txt based on the following condition.
Select data from text file that has a category of "Salads" and only return the name of the Salad to a text file.
test.txt contains the following data
1062,9971,Small Salad,,"40:""Salads"
1063,9972,Large Pizza,,"60:""Pizzas"
1065,9972,Large Salad,,"40:""Salads"
Desired output
Small Salad
Large Salad

Here's a couple options. Import the file as a CSV file, but only import the first three sections between commas. For instance, the first line of your test.txt file would import as 1062, 9971, and Small Salad. Then check for the word salad and write it out
if it exists. Here's an example.
$File = Import-Csv -Path C:\test\test.txt -Header One,Two,Three
Foreach ($Entry in $File) {
If ($Entry.Three -like '*salad') {
Write-Output $Entry.Three
As well, you could import all the contents of the file by changing the -Header parameter to One,Two,Three,Four,Five. Doing this, however, will mangle the data in Five because of the double quotes: "40:""Salads" would become 40:"Salads.
Then you could do this the way to wanted to do this, by checking the category of salads. Here's an example of this, as well.
$File = Import-Csv -Path C:\test\test.txt -Header One,Two,Three,Four,Five
Foreach ($Entry in $File) {
If ($Entry.Five -like '*salads') {
Write-Output $Entry.Three
Update: There are ways to read it in as a text file using Get-Content and then scanning each line, but because your source file has comma deliminators, it makes better sense to read it in as a CSV. To write this to a file, replace the Write-Output command with
Add-Content -Value $Entry.Three -Path C:\test\output.txt

Why does Read from Text file default to array of 9 elements

I am writing to a text file starting with a type def. cluster (control) of say 15 dbl numeric elements, that works fine I open the tab-delimited text file and all of the elements appear in the file. However when I read from the same text file back to the same type def. cluster (indicator), the read from text file defaults to 9 elements?? Is there a way to control how many elements are read from the file. This all works great when I initially use a cluster of 9 elements and read back to a cluster of 9 elements.
Solved!

From the LabVIEW Help: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/array_to_cluster/
Converts a 1D array to a cluster of elements of the same type as the array elements. Right-click the function and select Cluster Size from the shortcut menu to set the number of elements in the cluster.
The default is nine. The maximum cluster size for this function is 256.
Aside: so, how many times has this question been asked over the years?

How to open saved files using 'read from text file' function

Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?
Here are some screenshots on part of my program
let me know if you guys would need more information / screenshots thank you!

Ohmy, thanks altenbach. oh yeah i forgot about those sub VIs. will upload them now. Was rather demoralized after reading the comments and really struck me on how weak i'm at on labview really hope to get this done. But of course i have to study through and see how it works. Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.
( ps . cant connect it now unless my program is working otherwise labview will crash )
( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )
The sample code of ThoughtTechnology is named as attachment.ashx.vi. too bad i cant use it and present it as my project

LabVIEW for ARM 2009 Read from text file bug

Hello,
If you use the read from text file vi for reading text files from a sdcard there is a bug when you select the option "read lines"
you cannot select how many lines you want to read, it always reads the whole file, which cause a memory fault if you read big files!
I fixed this in the code (but the software doesn't recognize a EOF anymore..) in CCGByteStreamFileSupport.c
at row 709 the memory is allocated but it tries to allocate to much (since u only want to read lines).
looking at the codes it looks like it supposed to allocated 256 for a string:
Boolean bReadEntireLine = (linemode && (cnt == 0));
if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;    //BUFINCR=256
but cnt is never false since if you select read lines this is the size of the file!
the variable linemode is also the size of the file.. STRANGE!
my solution:
Boolean bReadEntireLine = (linemode && (cnt > 0)); // ==
if(bReadEntireLine) {    //if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;
and now the read line option does work, and reads one line until he sees CR or LF or if the count of 256 is done.
maybe the code is good but the data link of the vi's to the variables may be not, (cnt and linemode are the size of the file!)
count should be the number of lines, like chars in char mode.
linemode should be 0 or 1.
Hope someone can fix this in the new version!
greets,
Wouter

"LabVIEW for ARM guru and bug destroyer"

I have another solution, the EOF works with this one.
the cnt is the bytes that are not read yet, so the first time it tries to read (and allocate 4 MB).
you only want to say that if it's in line mode and cnt > 256 (BUFINCR) cnt = BUFINCR
the next time cnt is the value of the bytes that are not read yet, so the old value minus the line (until CR LF) or if cnt (256) is reached.
with this solution the program does not try to allocate the whole file but for the max of 256.
in CCGByteStreamFileSupprt.c row 705
if(linemode && (cnt>BUFINCR)){
cnt = BUFINCR;
don't use the count input when using the vi in line mode. count does not make sense, cnt will be the total file size. also the output will be an array.
linemode seems to be the value of the file size but I checked this and it is just 0 or 1, so this is good
update: damn it doesn't work!

Trying to parse a file-read from text file.vi

I'm attempting to read a txt file that has tab separated data. In the fourth (or any) column is the only data I need. The data is a string of numbers (23.454).
I've used the Read from Text File.vi and the Read From Spreadsheet.vi and I just don't seem to have enough LV background to extract the pertinent data into a graph. any suggestions?

(It is silly to use "delete from array" if all you want is a column. The correct function is "index array")
Joe's idea above basically works fine. Here's a quick adapdation (the node before the graph is "index array" from the array palette.).

Set a timeout for "read from text file"

I Need to read from a text file on a remote pc and use the read from text file function to do this. It wotks but sometimes this pc is down causing long wait times in my vi.
Is there a way to set a timeout for the read from text file function, or is there an other solution?
Thank you

You could check that the path is valid first before you attempt to read the file. hen put the file read in a True-False case structure based on the results of the check. You can use the function "Check if File or Folder Exists" It checks whether a file or folder exists on disk at a specified path. This VI works with standard files and folders as well as files in LLB files. The function is found in the File I/O --> Advanced File Functions palette.

Read from text file vi won't read file...

I am very new to LV programming so I hope you forgive any stupid mistakes I am making.   I am using Ver. 8.2 on an XP machine.
I have a small program that stores small data sets in text files and can update them individually or read and update them all sequentially, sending the data out a USB device.   Currently I am just using two data sets, each in their own small text file. The delimiter is two commas ",,".
The program works fine as written when run in the regular programming environment. I noticed, however, as soon as I built it into a project that the one function where it would read each file sequentially to update both files the read from text file vi would return an empty data set, resulting in blank values being written back into the file. I read and rewrite the values back to the text file to place the one updated field (price) in it'sproper place. Each small text file is identified and named with a 4 digit number "ID".   I built it twce, and get the same result. I also built it into an installer and unfortunately the bug travelled into the installation as well.
Here is the overall program code in question:
Here is the reading and parsing subvi:
If you have any idea at all what could cause this I would really appreciate it!
Solved!
Go to Solution.

Hi Kiauma,
Dennis beat me to it, but here goes my two cents:
First of all, it's great to see that you're using error handling - that should make troubleshooting a lot easier. By any chance, have you observed error 7 when you try to read your files and get an empty data set? (You've probably seen that error before - it means the file wasn't found)
If you're seeing that error, the issue probably has something to do with this:
Relative paths differ in an executable. This knowledge base document sums it up pretty well. To make matters more confusing, if you ever upgrade to LabVIEW 2009 the whole scheme changes. Also, because an installer contains the executable, building the installer will always yield the same results.
Lastly, instead of parsing each set of commas using the "match pattern" function, there's a function called "spreadsheet string to array" (also on the string palette) that does exactly what you're doing, except with one function:
I hope this is helpful...

'read from text file' erases the file

I am trying to read text in from a text file. This is the exact code I am using. For some reason the output from 'read from text file' contains all the text that was originally in the file, but after the code executes the file is empty. I have several other vi's which use the same code and the file is fine. But whenever I run this code in this one specific vi the text file gets erased.

What is in the rest of that "specific vi"? I just tried the code you show, in v2011, and it works as expected, doesn't clear file.
What version are you running? Can you add an error out, or make sure error output is on in your LabVIEW configuration?

Read from Text File - Help Bug?

Hi - I am currently working on LV8 and I think that there is some misunderstanding potential in the help file. To be more exact in the help to the "Read From Text File" VI.
The description for "count":
" ... If count is <0, the function reads the entire file. The
default is –1, which indicates to read a single line if you placed a checkmark
next to the Read Lines shortcut menu item and to read the
entire file if you removed the checkmark next to the item. "
If count is lower than zero, the function reads the entire file. That sounds clear to me.
The default is -1, which indicates to read a single line if you placed a checkmark next to the "Read Lines" shortcut menu item. Now what? Does it read a single line or the whole file?
.. and to read the entire file if you removed the checkmark next to the item. I thought it reads the whole file if I use -1 ?
the VI itself behaves as I'd expect it to:
* If I place a checkmark next to Read Lines and put -1, I get an array containing the lines
* If I remove the checkmark, I get only a single string item.
Now where is the error? Is the VI not working properly or only the description a little bit ... strange ?

?hein??
?what?
Both you guys lost me..
And I drink coffee without sugar (being sweet enough, already)
Here is what I get from Context Help on the Read From Text File:
Read from Text File
Reads a specified number of characters or lines from a byte stream file. By default, this function reads all characters from the text file. Wire an integer value to count to specify how many individual characters you want to read starting with the first character. Right-click the function and place a checkmark next to the Read Lines option in the shortcut menu to read individual lines from the text file. When you select the Read Lines option in the shortcut menu, wire an integer value to the count input to specify how many individual lines you want to read from the file starting with the first line. Enter a value of -1 in count to read all characters and lines from the text file.
Humm.
New feature (again).. If you select checkmark the Read Lines option, it will not send the text to a sting indicator, as shown in the attached image. If selected, then it's expecting to write lines to an array of strings... WHY??? I don't know.. I'll ask..
Strange... LV8 is full of mysteries...
