Write to text file qeustion

Hello all,
My first question about writing to text file is does the file need to be opened? i know you have the option to create, replace, open..., but does it need to be opened in order to properly write data to the file? Also if my application is running with a disk streaming file setup and i open the file that it is writing to will this cause an error or cause labview to lose control of the file and possibly stop writing to the file?
Thank you,
Matt

Feel free to experiment.  Try writing to a file from multiple locations at once, and you'll see race conditions where data could be lost.
The reason for the Open, Write, Close type of software is because generally you are in a loop continually writing to a file, and the extra overhead of a Open and Close can be limited to when the software starts and closes, instead of having to open a new reference and close it every time you want to write to the file.  Just open the reference once, work with it in a while loop, then close it once, must more efficient and better for applications that write many times to disk.
Is it necessary?  No you can just use the Write to Text file giving it a path and data to write, but behind that function it will need to open and close the reference each time.

  • Write to Text File.vi Output file all but first line start with tab

    The attached PNG shows the code used to build up concatenated strings into a string array for the first four lines, thence to a string Array, to Spreadsheet String.vi and, finally, the use of Write to Text File.vi
    The lower right corner shows the result loaded into a spreadsheet. Note the 3 blank entries marked by a filled red rectangle. Examination of hidden characters shows there is a tab at the beginning of lines 2, 3 and 4.
    There is no tab shown in the code. How do those tabs get there? How do I stop them?
    I have tried with the option "Convert EOL" both on and off with no difference.
    The Help states that an OS-dependent EOL character is appended to each line. I can't imagine the Windows EOL character includes a tab.
    Solved!

    I am still puzzled as to why those additional tabs were added by Array to Spreadsheet String.  I'm holding in my hand a printout of an old LabVIEW 8 program with that construction, which is known to work properly.
    Makes complete sense when you look at your code.  You build a string, including an end-of-line character, and put that string into an array.  Then, when you run it through Array to Spreadsheet String, it puts a tab after every array element, and new line at the end of each row in the array.  The first element of your array contains a new line but Array to Spreadsheet String doesn't know about it; it still inserts a tab between that array element and the next one, giving you the tabs.

  • Write to text file problem

    I have a write to 'text file' in a sub vi. It is a popup where user can change his program.
    For some reason, only the first time it is called, it actually writes to the text file.
    As long as the sub vi is in memory, and I call it again and press ok to write to text file, nothing happens.
    I've tried 'close file', but that doesnt help. Deleting the files from the disk before again calling the sub vi doesnt help either, it wont write
    to file again. Is this a bug or am I missing something?! Im on labview 2010

    Post your VI (along with sub-VI's if any).

  • Write to text file. Append to existing file. Create file if file doesn't exist.

    Hi folks,
    up to LabVIEW 7 there was a wonderful "Write to Text File" vi which allowed the option "Append to File". Now, in LabVIEW 8, this old vi is not longer supported anymore. Instead, I am suggested to use a new "Write to Text File" vi. This vi does not offer the option "Append to File" anymore. Rather it is proposed in the online help that one should use the "Set File Position" in order to append text to the file. This much less straightforward than the old solution. Furthermore, I miss an option which would create the complete path if it doesn't exist yet.
    To summarize: Isn't there really any smart "Write to Text File" vi available which offers both the options "Append" and "Create path if file does not yet exist". Of course, I could write such a file on my own but I am sure that it is of such general interest that it already exist. In any situation, when a log file shall be written, the wanted vi would be ideal.
    Thanks a lot,
    Peter

    Ray,
    I know that the old vi is still available. See the screenshot which I attach to this message. What I am missing is an option "Create file or even complete path if file or path do not yet exist.". Is there any reason why NI doesn't provide neither this option nor a simple "Append to file" functionality in the new "Write to Text File" vi?
    Regards,
    Peter

  • Write to text file returns no error even if the underlying file is deleted

    Hi,
    I'm using a CompactRIO and writing to a text file underneath the C drive.
    I'm running into an unexpected situation when I am trying to error check my file handling.  I assumed that if the underlying file being written to that was created by open/create/replace vi and written to with the "Write to Text File" vi, would return an error if I delete the file from underneath it in the file system., yet there is no reported error and the function carrys on seemingly successfully writing to a file that has been deleted.  
    Anyone know why this happens and how to potentiallly remedy?

    Ouch, this obviously isn't ideal but is probably down to the filesystem on the CompactRIO.
    I would consider putting in a check - doing something like getting the file position from the file might return an error if the file no longer exists.

  • "Write to text file" when button is pushed?

    I want to use the function "write to text file" when a button is pushed, and write only once.
    The same goes for "read from text file

    Hello!
    Look at the following examples shipped with LabVIEW Professional and LabVIEW Full. Event structure example is not installed with Base package. 
    Open up 'Example Finder', click on the 'Search' tab, enter keyword 'events' and you fill find several examples. The ones of interest for you is 'New Event Handler.VI" and 'Old Event Handler.VI', where the first uses the event structure and the other uses the standard state machine architecture.

  • Write to Text File - unflatten channel string

    Hi all,
    This is my first post on the forums!  It's been very helpful for me but I have not been able to find a solution to my (simple) problem.
    Operating system: Windows 7 (64-bit)
    Labview 2012 Full Development
    I'm using the DAQmx unflatten channel string to get the names of the channels, and when I Write to Text File, I get the names of channels to be displayed vertically, ie a new row for each channel in a column.  I'd like to "transpose" this, but obviously you cannot transpose a 1d array.  Any ideas on how I can do this?
    Any and all ideas are appreciate, thank you in advance,
    -AK
    Solved!
    Go to Solution.

    Show us how you are doing this.
    My guess is that once you get the data, you have linefeed characters separating the channel names rather than some other delimiter such as a comma or a tab.
    Depedning on how you are going from the channel names to the file (a string, an array of strings, Write to Spreadsheet File, Write to Text file, ....) will determine the best way to fix the problem for you.

  • Write to text file while scrolling table issue

    Hi all,
    I have a LabVIEW application that logs data using 'write to text file' every second. This is a bckground task in a sub-VI. On the main screen I have several tables that have scrollbars. Every time the file is written the scrolling of a table is effectivley canceled. It is then necessary to click on the scrollbar again to re-start scrolling the table. I guess this is an issue with the OS but not sure yet. I have not tested other operating systems yet. I thought I would try the forum first. Has anyone else experienced this issue? Any ideas on how to fix this?
    I have tried using list boxes instead of tables but the same issue exists.
    I'm using windows 7 and LabVIEW 2011.
    Thank you.
    Certified LabVIEW Architect

    Hi Steve, thanks for offering to help. Right now I'm on a machine with LabVIEW 2010 and XP and the issue does not exist. But I have created a little test VI that should demonstrate the issue once running on LabVIEW 2011 SP1 and Windows 7. I can't confirm this VI will demonstrate the issue until later today when I can test it on the problem system myself. Feel free to give it a go and let us know what you find, or wait until I confirm the attached VI will demonsrate the issue (10 to 12 hrs time).
    Thank again.

  • From PLSQL - Need to write a text file

    I need to write a text file from data retrieved from many tables in PLSQL to the UNIX box.
    Thanks

    You can use package UTL_FILE to write out to a file. Your DBA has to make initialization changes to support this. They might already have it setup. Run this query:
    SELECT value
    FROM v$parameter
    WHERE name = 'utl_file_dir';
    To see whether it has been configured properly. The value is the directory where you can create and write files.

  • How do I read and write to text files on a remote computer's hard drive

    I would like to read and write data to a text file on a remote computer. This is easily accomplished using one of the file functions such as "write characters to file.vi". If I am already connected to the remote computer, all I need to do is specify the path to the particular file and it will work fine.
    My problem is that I want to connect to the remote computer programatically within LabVIEW (I do not want to have to use the computer's OS to establish the connection. Is there a function that I can use to do this?

    Yariv,
    You should really start a new thread with a new question like this, so that more people see it. Some people look primarily at threads that have no responses yet. Also, don't post the exact same question in multiple places. Or, if you must cross-post to some other forum, make sure to mention it in your question text.
    I'm happy to be a brick in your Western Wall, but I'm not sure what the main objective is here. Is the main problem really getting access to the "X bytes received in Y seconds at Z bytes/sec" string? Or is it accomplishing the file transfer? And what OS and LabVIEW version are you running?
    I think your problem is that you the LabVIEW System Exec command does not allow for the degree of interactivity that you need if you want to issue a sequence of commands to a command-line executable. However, under Windows XP (and, presumably, other Windows versions, though I can't check), you can tell the FTP executable to use commands from a textfile script by using the -s switch, and you can override the prompts during multiple file transfers with the -i switch:
    ftp -i -s:FILEPATH SERVERNAME
    If you issue a command in this format to System Exec, and make sure to create a file at FILEPATH with your command sequence (one per line), then you should at least accomplish the FTP actions. This won't give you the transfer details in the standard output, unfortunately. However, if you just want a general sense of how much was transferred and how quickly it happened, you can code that in LabVIEW by getting the resulting file sizes and using Tick Count before and after the System Exec call to see how long the transfer took.
    Hope that helps,
    John

  • How can I write to text file colorful texts

    I save system events in a text file,for example when system give warning message i want to write it red

    As others have mentioned, if you want to view text in different colors with an viewer/editor tool outside of LabVIEW, you must provide the necessary formatting for that tool.
    If it works for your application to view the file using LabVIEW you can do this:
    1) Place a unique key in each line that identifies an error.
    2) Display the text in a Listbox and color each line based on that unique key.
    You can fairly easily provide a stand alone viewer if needed.
    This technique can also be expanded to provide multiple colors.

  • Is it possible to read/write to text file without deleting it?

    I know how to read from a text file and how to write to a text file. The problem that i have is i need to use a text file to store data for my application to read and also for my application to write. I would like it if i could write two programs really, one reads, the other is used to update the text file. This file is a list of verbs. I thought about using databases but i couldn't get them to work. I downloaded MySQL server 5.0 and installed it. I then downloaded the driver from http://www.mysql.com/products/driver and ran the auto installer. it said everything worked out perfectly but when i try these lines:
    Class.forName("com.mysql.jdbc.Driver");
    I get a SQLException that says no suitible driver
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    ( I thought this driver came with the JDK but i guess not, i just read about it in a java book)
    I get a ClassNotFoundException
    that just says sun.jdbc.odbc.JdbcOdbcDriver
    So yeah, SQL is pretty much not working. I need a solution to my problem, either by using text files, or a different type of database. I heard you could use excel to create a database but i have no idea how and i hear microsoft access could also do this, however i don't have microsoft access and i don't intend on paying for it. So, here are my questions:
    1st, is there a tutorial on using excel databases in java programs
    (if not)
    2nd is there a way to read/write/update a text file without deleting it?
    (if not)
    3rd is there a way to get SQL working, i have windows vista this could be the problem
    (if not)
    4th what could i do to store information on the hd for reading and modifying later?
    thanks, lateralus

    A database might be overkill just for a list of words.
    Thoughts:
    <ul>
    <li>What is the extent of your "file updating"? If you are just appending to the file, opening it in append mode will keep the file from being clobbered.</li>
    <li>Otherwise, why not create new files instead of editting them? The file names could include a version number or timestamp, allowing the reader to select the newest one.
    </li>
    </ul>

  • Fail to write the text file

    hi,
    I met a problem when I try to store data to text file. That's the description:
    - To read some objects from the binary file
    - To update object state, do some operations
    - To output some properties of the object to text format file.
    That's a part of my code:
    {color:#0000ff}
    //------ begin ---------//
    // ".cluto" is a binary file where store the number of objects as the first object and a set of docVector object
    File cluto = new File (config3.getOutputPath (), config3.getOutputFileType () + ".cluto");
    ObjectInputStream reader1 = new ObjectInputStream (new BufferedInputStream (new FileInputStream (cluto), BUFFERSIZE));
    // output text file definition
    File rlabel = new File (config3.getOutputPath (), config3.getOutputFileType () + ".rlabel");
    BufferedWriter rlabelWriter = new BufferedWriter (new FileWriter (rlabel), BUFFERSIZE);
    // get the first object in ".cluto", the number of objects in the input binary file
    Integer vectorNumber = (Integer)reader1.readObject ();
    // temporal variable
    docVector tVector;
    for(int i=0; i<vectorNumber.intValue (); i++) {
    tVector = (docVector)reader1.readObject ();
    tVector.dimsPruning ();
    tVector.updateDimsWeight (config1.getWEIGHT_TYPE ());
    rlabelWriter.write (tVector.vectorLableToString ()); // tVector.vectorLabelToString() return a string!
    reader1.close ();
    rlabelWriter.flush ();
    rlabelWriter.close ();
    //------ end --------//
    {color}
    The program works and creates the file ".rlabel", but a binary file instead of text file! Anyone have ideas about this problem?
    Thanks

    Sorry, I means ".rlabel".
    Good news, I fix the problem. In my old code, the I/O stream keeps always opened when I write huge data to the file (See "for" loop). And after the loop, I close the stream.
    Now, I open and close the stream in each loop. The problem is resolved.
    that's the new code:
    // this function is used to write a string to a file
    /* write a string to a file */
    public void writeStringToFile (String content, String fileName) {       
    BufferedWriter writer = null;
    try {
    writer = new BufferedWriter (new FileWriter (fileName, true));
    writer.write (content);
    writer.close ();
    } catch (IOException ex) {
    ex.printStackTrace ();
    String rlabel = "test.rlabel";
    for(int i=0; i<vectorNumber.intValue (); i++) {
    tVector = (docVector)reader1.readObject ();
    tVector.dimsPruning (prunedTerm);
    writeStringToFile (tVector.vectorLableToString (), rlabel);
    //------- end ----------//
    I don't know whether the open/close operations in a large loop cost a lot.
    Thanks
