Write to the spreadsheet file (how to start new lines)

I'm reading signals from a hardware device and try to write it in several columns using Scripture in the spreadsheet file every few seconds.

My problem is every time a new signal comes in, my program seems to overwrite the previous signal when writing to file, when (say after 2 minutes), I go to check the written file, it shows only 1 row of information. How can I fix?

Part of my VI and the output file is attached.

If the program segment shown in your picture is inside a loop, then the section header write overwrites the file each iteration of the loop.  So, you see only the data for the last iteration.  Solution: Move portions header to write and write the names of channel out of the loop or put them in the case of structures that run only when you want a new file or new channels.

  • Write to the spreadsheet file

    Hello

    I try to write in a spreadsheet file.

    There are two things that I try to do what does not the current .vi.

    1. ask a name of file to outside the while loop. For the moment, this happens inside the while loop.

    2. Add to the file (by setting true) does not work as each time the while loop is iterated in this example, it asks me for a new file name. Shouldn't it just add to the file without having to ask a new file name on each iteration.

    Thank you

    If you do not specify the path to the file and then writing on a spreadsheet file asks for the file.  That just the way the function works.  If you go to the range of advanced functions of file, you will find a file dialog box function.  Put outside your loop and pass the path resulting in the loop and writing in the spreadsheet file.

  • Problem with 'Write to the worksheet File.vi' in Labview 8.2

    Hello

    I wrote a vi to reduce the noise of my source of signal (voltage). When I wrote in the spreadsheet file, it saved only 10 rows of data. How can I continue to record the signal until I stop the vi.

    Thanks in advance,

    Michael

    How many samples you take with the DAQ Assistant? Is it ten?

    Please pay attention to the answers. You never want to save more than one iteration until correct you the entry in the spreadsheet file.

    Post your VI if you still have questions after the fixing of the VI.

  • Setup cannot write to the destination file

    I try to install software on Windows 7 that has always worked well in XP and earlier versions of Windows.  When I run the Setup on Windows 7 routine, I get:

    Can someone tell me how to deal with this?  It seems to be a security problem, but I have no idea what to do about it.

  • Is there a file size limit when using read the spreadsheet file?

    I'm reading in a large file, approximately 52 MB, 525600 lines with 27 fileds in each line using "Read SpreadsheetFile.vi". I then explore table 2D-999, which represents bad/no data in this area and the total number of fields with-999 in there. All works on 3 months ' worth of data. The program is giving me a memory error output and stopping in case reading takes place on the file of the year a large. So my question is that the reading of the spreadsheet file has size limitations? Is there a better way to do it? Thanks in advance for the help.

    Or just use Notepad to display the file instead of Excel.

  • "Not able to write to the configuration file" when config editor in the admin tab

    Hi guys,.

    I have install OBIEE 10.3.3.4 on a GNU / linux RH (with OS user obiee) and Oracle Application Server 10.1.3.1 on the same box (with OS user oraias).

    When I want to change some settings in the admin tab of BI publisher (administrator/administrator under the name of login/pass) and click "apply."
    I get the error "could not write to the configuration file. Once I changed the configuration to 777 properties, the error is still there. And I also try to change the SECURITY MODEL to the MEO, but still no use.

    I did a test, for example, when I change something in the admin - JDBC - Oracle BIEE and apply then I got the error. If I update xmlp/DataSource/datasources.xml manually, the change can be seen after that I opened the admin of page - JDBC - Oracle BIEE. That means I have find the right file and the file access properties is ok.

    Other parameters such as the Scheduler Configuration, I had the same error when apply. But the "Test connection" and "Installation diagram" function.

    Can someone give me some advice on this? Thank you

    Scott

    In what way is your xmlp? You are absolutely sure that the user of the OAS (oraias) can write to this file? If you have used another user for OBIEE then your will need to change the owner of the file or put them in the same group, and change the file permissions.

    I run an application in run in continuous mode.

    One of the variables change over time (it is inside a while loop and is part of the task of data acquisition). I want to record all the values this variable can take during execution and save them in a spreadsheet file?

    How this can be done?

    Give this example look on.  I am open a file before the beginning of my main loop and its closure after the main loop.  Inside the loop, I am formatting my data in a string of tabs.  I then save this string in the file.
