Updating data from a text file in DW is it possible ?

Hello,
I would like to know if there is a way to update
info that I originally input into DW from a .txt file
using the insert tabular data command.
If anyone know if this is possible, I'd really appreciate
knowing this. I don't mean via means of using php, or anything like
this.
I am talking about updating info in cells on a local
computer.
So for example, a .txt file gets updated, and in turn, DW
will auto-update the table content it sees in the updated .txt
file, or other type of data file.
Thank you for any info

It really depends on how you've saved the data. If you have a simple text file with x data in one column and y data in another, then you can use the code below. It's just a Read From Spreadsheet File, and Index Array, and Bundle function. Modify as needed for your actual data. If you get stuck, post a small example of your data file.

How do you read data from a text file into a JTextArea?

I'm working on a blogging program and I need to add data from a text file named messages.txt into a JTextArea named messages. How do I go about doing this?

Student_Coder wrote:
1) Read the file messages.txt into a String
2) Initialize messages with the String as the textSwing text components are designed to use Unix-style linefeeds (\n) as line separators. If the text file happens to use a different style, like DOS's carriage-return+linefeed (\r\n), it needs to be converted. The read() method does that, and it saves the info about the line separator style in the Document so the write() method can re-convert it.

How can I plott data from a text file in the same way as a media player using the pointer slide to go back and fort in my file?

I would like to plott data from a text file in the same way as a media player does from a video file. I’m not sure how to create the pointer slide function. The vi could look something like the attached jpg.
Please, can some one help me?

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

How to parse data from a text file with no convenient delimiters?

I need to read data from a text file. This file contains one line of data with the repeating pattern "time 00 ADVar2: ___ Height: ____ time 01 ADVar2: ___ Height: ___ ..." I need LabView to parse out the "time" and "height" values, build an array with the values, and graph the correlation on an X&Y plot. Does Labview have an automated way to read to the input data file and parse out the correct values, even without convenient delimiters? Thank you.

You actually do have a convenient delimiter: "time". Thus, you can make an array using that as the delimiter. Only caveat is that the first array element will be empty. Then you can conveniently use the Scan From String function in a for-loop. Something like this:

Read data from a text file, one line at a time.

I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.

The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.

How can I use Automator to extract specific Data from a text file?

I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY
Random
Text
161 179
bytes of CODE    memory (+                68 range fill )
16 789
bytes of DATA    memory (+    59 absolute )
1 875
bytes of XDATA   memory (+ 1 855 absolute )
90 783
bytes of FARCODE memory
What I would like to have as a final file:
EXCEL COLUMN1
Column 2
Column3
Column4
Column5
Column6
MM/DD/YYYY
filename1
161179
16789
1875
90783
MM/DD/YYYY
filename2
xxxxxx
xxxxx
xxxx
xxxxx
MM/DD/YYYY
filename3

Is this possible? I can't imagine having to go through each and every file one by one. Please help!!!

Hello
You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);
#     CSV spec
#     - record separator is CRLF
#     - field separator is comma
#     - every field is quoted
#     - text encoding is UTF-8
local $\\ = qq(\\015\\012);    # CRLF
local $, = qq(,);            # COMMA
# print column header row
my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
# print data row per each file
while (@ff) {
    my $f = shift @ff;    # file path
    if ( ! open(IN, '<', $f) ) {
        warn qq(Failed to open $f: $!);
        next;
    $f =~ s%^.*/%%og;    # file name
    @dd = ('', $f, '', '', '', '');
    while (<IN>) {
        chomp;
        $dd[0] = \"$2/$1/$3\" if m%Link Time\\s+=\\s+([0-9]{2})/([0-9]{2})/([0-9]{4})%o;
        ($dd[2] = $1) =~ s/ //g if m/([0-9 ]+)\\s+bytes of CODE\\s/o;

How to read a tab seperated data from a text file using utl_file

Hi,
How to read a tab seperated data from a text file using utl_file...
I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....
Thanks in advance...

It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

How to do import data from the text file into the mathscript window?

Could anyone tell me how to do import data from text file into mathscript window for labview 8?
MathScript Window openned, File, Load Data - it has options: custom pattern (*.mlv) or all files.
Thanks

Hi Milan,
Prior to loading data in Mathscript Window , you have to save the data from the Mathscript window (the default extension of the file is .mlv but you can choose any extension). This means that you cannot load data from a text file that was not created using the Mathscript window.
Please let me know if you have any further questions regarding this issue.

Need to read data from a text file

I need to read data from a text file and create my own hash table out of it. I'm not allowed to use the built in Java class, so how would I go implementing my own reading method and hash table class?

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
[http://java.sun.com/docs/books/tutorial/essential/io/]
*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

Error while loading data from a text file to a datastore

Hi all,
i am a starter in ODI. I am trying to load data from a text file into a datastore. I have put the file on a unix server whose location is defined in the topology manager. when i am trying to "view data" it is giving me error file does not exist at <location where i have put the file>. Please help me

Hi,
1. If your files are on a remote File System, you will need to copy one of your files to the machine ODI Designer is running on to allow ODI to retrieve the metadata information of the file.
2. In Topology create a Physical Schema, the directory you enter for Data and Work Schema should point at this local file.
3. Then define the File Datastore in ODI Designer. Enter a name, browse and select the file and fill in each filed of the Files tab.
* If its a Fixed file, click on the grid icon on the Columns tab to enter the columns and have Automatic Adjustment checked.
* If its a Delimited file, use the Reverse button on the Columns tab to reverse the columns.
* Right click on the File Datastore select View Data, if you can view data, that means the File Datastore has been defined correctly.
* If not, check each tab of the File Datastore to make sure everything is defined correctly and retry.
4. Once View Data is successful, you now change the directories (Data and Work Schema in Topology) to point at the remote File System. These directories must be accessible to the ODI Agent that will be used to run the transformations. The directory can be an absolute path (m:/public/data/files) or relative to the ODI Agent startup directory (../demo/files). It is strongly advised to use a UNC (independent from the execution location) for the path. When running the transformations with "no agent", the directory is relative to the directory where Oracle Data Integrator has been installed.
You need to have a agent process running at the system where your source file resides .
Then while running the odi interface choose that agent .
Thanks,
Sutirtha

Average Data from multiple text files

I am new to labVIEW hence a little help is appreciated:
I have a 100 txt files with two columns (tab separated) for X and Y value.
I need to average the Y values to generate one single txt file and generate X versus Y graph.
So how do I read the data from these text files? (without having to select each one of them individually) and how to average the data and create a XY graph from it?
Thanks in advance
Solved!
Go to Solution.

Use X-Y Graph.
You were able to get two arrays of X and Y points from text file right?

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

Adding data from a text file into a JTextArea

I'm working on a blogging program and I need to add data from a text file named messages.txt into a JTextArea named messages. How do I go about doing this?

then you need to be more specific in what you need help with because those are two commonly used options for reading data in from a file. what have you tried? where is your code failing? what kind of errors are you getting? of course it looks like others in the forum have already reprimanded you for failing to post properly.

Interactive Bar/pie chart and line graph, data from excel/text file -urgent

Hi,
I have a huge data in excell sheet which keeps updating every month. Data basically consists of service provider and there respective subscribers from various regions of the country over the years. The requirement is to give the viewers an interactive page where in they can make various combinations and can compare, cross examine data according to thier choice.
We want the pie chart / bar graph or line graph to be created on the fly according to the combination made by the user.
The site is hosted on a red hat linux server. how can a connection to the excel spreadsheet be made or is it possible to read from the text file if the entire data is exported to a text file.
Is there any ready made tool/code available which can be customised according to the need.
Thanx in advance
Regards
Prakash

I certainly wouldn't pay for the graphing package at the previous link. check out http://www.object-refinery.com/jfreechart/ for a free, open-source, much better looking graphing package.
