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.

  • Retriving data from a text file using vbs

    Hi all,
    Im relatively new at this, but want to delve right into it.
    I need to look for a string of text in a log file.
    When that string of text is found, I want to get the next 4 lines of text immediately after, see my example below:
    Example found text string
    first line after found string
    second line after found string
    third line after found string
    forth line after found string
    any help would be greatly appreciated,

  • 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.

    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

  • 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.

  • Need to read data from a text file

    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.

    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?

  • 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:

    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 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.
