Write to Spreadshee​t File

Hello,
I am trying to write to a spreadsheet file. 
There are two things which I am trying to do which the current .vi doesn't do. 
1. Ask for a file name outside of the while loop. At the moment this occurs inside of the while loop.
2. Append to file (by setting to True) doesn't work as every time the while loop is iterated in this example it asks me for a new file name. Shouldn't it just append to file without asking for a new file name on every iteration.
Thanks,
Solved!

If you don't specifiy the file path, then the Write to Spreadsheet File asks for the file.  That just the way the function works.  If you go into the Advanced File Functions palette, you will find a File Dialog function.  Put that outside of your loop and pass the resulting path into the loop and to the Write to Spreadsheet File.

  • Error 6 in write to spreadshee​t file

    Hello.  My program reads a 1D array of 12 values, then increments each value as the controlled components activate.  The program then writes the new value back to the file, replacing the old value.  After running for a time, I get the following error message:
    Error 6 occurred at Open/Create/Replace File In Write Spreadsheet STring.vi->Write To Spreadsheet File (DBL).vi->(name of my vi.)
    I read some posts which said that this could be a problem of the file getting too large.  Since I am writing over the same values, how can this happen?
    Does anyone have any suggestions as to what can be done to prevent this error?  If the file is getting too large, how can I prevent this from happening? 
    This is my first time posting.  Is there a better way to attach a pic of a vi/block diagram than what I have done?

    For future reference, it is best if you just post the VI itself.  It will make it easier on us to help.
    Does the file increasing in size?  You can simply look at the file in Windows Explorer to find that out.  It also bothers me that you are rewriting the file so often.  Why not only write the file once the loop is complete?

  • TS1717 unes, i have windows 8, i get the message, "the itunes Library .itl file is locked, on a locked disk, or you do not have write permission for this file.  how did this happen, how do i fix this?

    the message"The itun, library .itl file is locked, on a locked disk, or you do not have write permission for this file". i have windows 8. how why did this happen? how do i correct this and prevent another occurance?  I am able to access itunes on my i5, ipad, and my old i4 that i use solely as my ipod now. At the time  problem occurred, i was connected to ext hard drive that hold over 190GB music, to add to my library. I am now unable to add to my library using my laptop.  any advise/help is greatly appreciated!!

    I just had the same problem and was able to fix it after trying a couple of things I found after a search.
    The solution that worked for me:
    Find iTunes folder - it should be in C:\Program FIles (x86) or similar depending on your operating system
    Right click the entire folder (no need to open it) and click properties
    Click the security tab
    Click edit and highlight the user name under which you logged in.
    Click the box next to full in the allow column, which should check everything
    Click apply
    Open iTunes
    This worked for me.

  • How To Fix: "The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file."

    I can't reopen my iTunes after I have to force quit when it does not respond. I get this message:
    "The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file."
    I've read to do the solutions. I right clicked on both the iTunes and Music folder and went to info for each. On both the lock at the bottom of the Get Info was locked. All of my users including admin can read and write all files within those folders. They are even a shared folder. I clicked on the lock to unlock it, typed in my admin password, and went to the gear to apply to all files inside. After doing that I keep getting the saved message.
    I tried another way that I've found online to move my ituneslibrary folder to the desktop and then open my iTunes. In theory the iTunes is supposed to ask for where the iTunes library is. Once that is prompted you quit iTunes and drag the iTunes Library folder back to the folder from the desktop and reopen iTunes to apprently solve the problem. However, when I move the iTunes Library file to the desktop and try to reopne iTunes the icon just keeps bouncing and when I right click the application does not respond.
    This problem is only resolved if I restart/shut down my macbook pro which is a 15-inch Core 2 Duo with intel. It will be 5 years old in December. I currently have Lion and the latest iTunes 10.5. This problem started in late December. 

    If you hold down the option key when starting iTunes, it will allow you to select a library or create a new one.
    You can create a new one, and then add all of your iTunes music back in by simply dragging the old iTunes music file onto iTunes.

    How to make write access to a file using midlet and HTTP connection?
    I have text file in the Tomcat server and I am able to read it with HTTP connection using emulator, but don't have idea how to make write access to the file. I'd like to write some text to the file.

    Thanks, but could you be more accurate. What methods should I use in the servlet and what methods in the midlet?
    Some links which concern this subject, would be nice too. I have tried with google, no success.

  • ITunes won't open, I get this message: The iTunes Library .itl file is locked, on a locked disk or you do not have write permission for this file.

    iTunes won't open.
    I get this message: The iTunes Library .itl file is locked, on a locked disk or you do not have write permission for this file.

    This may indicate a corrupt preference file with iTunes trying to open the wrong location. Try holding down shift as you launch iTunes then choose the correct file, normally <User's Music>\iTunes\iTunes Library.itl. See iTunes: How to open an alternate iTunes Library file or create a new one.

  • Data Acquisition - using local variables to write data to a file

    Hello,
    I am running a Data Acquisition vi (currently in LabVIEW 7.1 but soon to be updated to 8.2) that collects ~100 parameters of data from several sources contained in a while loop. The current configuration (which I did not write) uses very few subVIs and writes to ~100 local variables to store each parameter. It then reads all the local variables and builds an array of all the strings, converts then to a spreadsheet string, then uses the write characters to file function to append to a datafile. I am trying to clean things up and have came up with subVIs to collect the data from the following sources:
    8 serial port sources collecting btwn 8 and 20 parameters each
    ~15 thermocouple readings
    ~10 analog inputs
    ~20 parameters read off an ARINC 429 bus.
    I have come up with a subVI to read each of the sources and have placed the subVIs in the while loop. Each subVI outputs the data that it collects in array or cluster form. I was wondering how best to write each parameter to a CSV file at between 1 and 10 Hz. Should I write each subVI output to a LV and then read them off as was done before (the difference being that I have reduced the # of LVs to ~10 vs >100?
    I should add that precise timing is not that important, so if all the subVIs are not collecting simultaneously (which I understand that they won't be), it does not really matter.
    Thanks.

    Hi jilla,
    jilla wrote:
    What I think that you are saying is to turn the outputs of the 4 subVIs into inputs of a 5th subVI that writes to the data file. Correct?
    Yes.  It may sound like a fine-point, but I beileve it's better to create a VI specifically for formatting data - in your example, 4 arrays IN, a single string OUT.  Then write the string to file as a seperate operation.  GUI-displayed data can go through a similar transformation, the four arrays wired to a subVI which builds output-structures specifically for display.  It's a beginner's mistake to put lots of individual controls and indicators on the screen when groups of them are naturally related (in an object-oriented sense.)  Use clusters to group related controls - this will keep the diagram much cleaner.
    One more question: at what point (either # of data points or frequency of data collection) does it become necessary to use queues? Thanks.
    Well, there's not really a clearly definable "point".  I'd say if your update-rate climbs above 100Hz, or you witness poor program or system performance, then it's time.  The scenario you've described is a fairly simple acquire/display&log loop - and simple is good.   Then-again people can't see/react-to updates faster than about 10Hz - so it doesn't make sense to sacrifice performance - if performance becomes an issue.
    Re: queues:  Queues are sometimes used to buffer data that's "produced" in one place and "consumed" in another.
    Here, if/when logging data, you're logging with every DAQ.  I wouldn't recommend using a queue to transport data from a "DAQ loop" to a "Logging-loop" - those functions can be in the same loop.  Should/could a queue be used to get data from a "DAQ loop" to update the GUI at a lower frequency?  Sure, but a Notifier might be a better choice.   Further, in the (simple?) program you've described, you might use a case structure (True/False) to only update FP indicators every "X" iterations - a simple solution that doesn't require Queues or Notifiers.
    Cheers!

    this may happen on external drives if:
    The external drive was hotpluged (removed) without going the correct "eject" way
    The iTunes library (database) got corrupted
    First Aid for external drive
    Close iTunes
    Unmount (eject) external drive the right way.
    Mount drive again
    Go to Workplace -> right click external drive -> choose "clean up" This will force the filesystem to rescan the file structure of the drive and rebuilding the file system table and journaling file.
    After the tool shows "done" (could last some time depending on size of drive) restart iTunes
    If your iTunes library is on your internal drive, this may happen
    The system was not shoot down correct, e.g. "pulled the plug"
    The iTunes library (database) got corrupted
    First Aid for internal hard drive
    Close iTunes
    Reboot system
    Go to Workplace -> right click external drive -> choose "clean up"
    After the tool shows "done" (could last some time depending on size of drive)
    Reboot system, restart iTunes

  • Need example with write to DATA log file programmatically?

    Hi all,
    I would like to request for an example of writing a datalog (*.DAT) file which could do this.
    Datalog file.
    NAME: AGE: SEX: (header)
    john 16 M (data)
    marie 55 F
    Dolah 34 M
    The program can also let me to add in new data and then store in the same file.dat. The data (hopefully) can be written to the bottom of the last saved entry of data. (eg. after the row Dolah).
    I need to do this so that I can open and read back the datalog file and use the data for other purpose.
    Please help,
    juni

    You've got some examples in Fundamentals>File Input and Output but one of the easiest things to do is to modify Write Strings to Spreadsheet File.vi to write strings as detailed at the bottom of the diagram and then save it to a different place and with a different name.

  • Java.util.logging: write to one log file from many application (classes)

    I have a menuapp to launch many applications, all running in same JVM and i want to add logging information to them, using java.util.logging.
    Intention is to redirect the logginginfo to a specific file within the menuapp. Then i want all logging from all applications written in same file. Finally, if needed (but i don't think it is), i will include code to write logging to specific file per app (class). The latter is probably not neccessary because there are tools to analyse the logging-files and allow to select filters on specific classes only.
    The applications are in their own packages/jars and contain following logging-code:
            // Redirect error output
            try {
                myHandler = new FileHandler("myLogging.xml",1000000,2);
            } catch (IOException e) {
              System.out.println("Could not create file. Using the console handler");
            myLogger.addHandler(myHandler);
            myLogger.info("Our first logging message");
            myLogger.severe("Something terrible happened");
            ...When i launch the menuapplication, it writes info to "myLogging.xml.0"
    but when i launch an application, the app writes info to "myLogging.xml.0.1"
    I already tried to leave out the creation of a new Filehandler (try/catch block in code above) but it doesn't help.
    Is it possible to write loginfo to same specific file?

    You should open/close it somehow at every write from different processes.
    But I personally prefer different file names to your forced merging, though.

  • Configure log4j to write to different log files conditionally

    Hi folks,
    Is there is way log4j could be configured to write to multiple log files conditionally? Let me try to explain what i am trying to do.
    I have two classes DatabaseChecker and FTPChecker extends Checker class. Within Checker class, there is a method logTestResult(CheckerType c, boolean isFailed, int retry, int isMaxRetryExceeded). Depending on the CheckerType(database or FTP), I need to write log outputs to different files (dbchecker.log or ftpchecker.log). How do i configure log4j to do this?
    I've seen how to configure log4j based on classes from different package, but not sure on this one. Any clue would be much appreciated.

  • How to read the data file and write into the same file without a temp table

    Hi,
    I have a requirement as below:
    We are running lockbox process for several business, but for a few businesses we have requirement where in we receive a flat file in different format other than how the transmission format is defined.
    This is a 10.7 to 11.10 migration. In 10.7 the users are using a custom table into which they are first loading the raw data and writing a pl/sql validation on that and loading it into a new flat file and then running the lockbox process.
    But in 11.10 we want to restrict using temp table how can we achieve this.
    Can we read the file first and then do validations accordingly and then write to the same file and process the lockbox.
    Any inputs are highly appreciated.
    Thanks & Regards,
    Lakshmi Kalyan Vara Prasad.

    Hello Gurus,
    Let me tell you about my requirement clearly with an example.
    Problem:
    i am receiving a dat file from bank in below format
    105A371273020563007 07030415509174REF3178503 001367423860020015E129045
    in this detail 1 record starting from 38th character to next 15 characters is merchant reference number
    REF3178503 --- REF denotes it as Sales Order
    ACC denotes it as Customer No
    INV denotes it as Transaction Number
    based on this 15 characters......my validation comes.
    If i see REF i need to pick that complete record and then fill that record with the SO details as per my system and then submit the file for lockbox processing.
    In 10.7 they created a temporary table into which they are loading the data using a control file....once the data is loaded into the temporary table then they are doing a validation and updating the record exactly as required and then creating one another file and then submitting the file for lockbox processing.
    Where as in 11.10 they want to bypass these temporary tables and writing it into a different file.
    Can this be handled by writing a pl/sql procedure ??
    My findings:
    May be i am wrong.......but i think .......if we first get the data into ar_payments_interface_all table and then do the validations and then complete the lockbox process may help.
    Any suggestions from Oracle GURUS is highly appreciated.
    Thanks & Regards,
    Lakshmi Kalyan Vara Prasad.

  • I've just opened iTunes on my Mac with an error "The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file.". I created a shirred library so that all users on my Mac can access the same library. Help?

    I have just opened ITunes on my Mac and the following error occurred "The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file.". When I setup my Mac I created a shared user area to contain my ITunes library so that I could share it with another user logged onto my Mac. However the error above gives me the impression that the library file is locked... I've checked and it does not seem to be locked under the "get info" fie information. Has anyone come across this before and found a solution?

    You also need to make sure you have both read and write permission for the file, or for the whole iTunes folder for that matter.  That's also done in Get Info for the file or folder concerned.
    Read the part about changing permissions on the iTunes folder in: https://discussions.apple.com/message/11583914
