• 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.

• Detection of folklore in "reading a spreadsheet file.

  Hi people,

  I need help in the detection of expressions of folklore in a "reading a spreadsheet file. I'd like to stop a while loop by plugging the expressions of folklore? the stop condition indicator, but it does not work. For resons design that I can't replace everything in a loop with a for loop and I don't need the while loop. I read something about creating custom detection of expressions of folklore, but I wonder why the builtin work in vi doesn't work and if it is not a simple solution.

  Thank you very much

  A native Excel file is NOT a text file.  It is a format of custom file created by Microsoft.  This is why you must use ActiveX to interact with him.

  The worksheet ' ' folder features found in the work of LabVIEW with text files (delimited by tabs, CSV, etc.).  The text files are a format more generic that can be read by programs such as Notepad.  Tried to use Notepad to open an .xls file?  It does not work.  Excel can open a text file, because it is a generic format.

  So even if everyone automatically thinks "Excel" when they see the word "Spreadsheet", the two are not synonymous.  In the case of LabVIEW, 'Spreadsheet' made reference to a delimited text file.

• Read a spreadsheet File.VI - conflicts of files?

  I hope it's an easy question. Anyone who is familiar with the "File.VI spreadsheet read" how access the files? Specifically, I am writing a VI to read a log file CSV that VI another written in. I want to do that there is no conflict if the other VI is written to the log file at the same time I'm trying to read. I know that I can copy the log file, read, copy and delete the copy to ensure there are no conflicts, but I prefer not to do that from a performance perspective. Any help would be great. Thank you!

  This VI uses the functions of e/s standard file, which is to open the file, read it and then close it. The open mode is set to 'read only', so as long as the other application is not having some kind of lock on the file (you don't specify what operating system you are using), you should be OK with just read the file. Of course, you may not get the latest content of the file, because it depends on when the OS actually flushes out the contents of the buffer to the file on the disk.

• Is VI file reading worksheet one reading % 3F

  I stumbled upon the reading of spreadsheet files VI and I was wondering if this is a read-only?  I am under the impression that it is not because in the Help menu is indicated the following:

  The VI then opens the file before reading it and the farm. You can use the VI to read a spreadsheet file, saved as text. This VI calls the String Array to worksheet function to convert the data.

  I usually use Create/replace and do a read only so I wonder if it is read only or read/write when it opens a file?

  Digging into the VI, I see that it uses the read-only permission to open and read the file.

• Incorporate the binary string in the string spreadsheet file

  Hello LabVIEW wizards...

  So I use scripture to VI file spreadsheet to create a beautiful layout, tabs-delimited report of one of my programs for the acquisition of data file. In one of the cells in the resulting worksheet file that I want to put a binary string of all my control values so when you open the data file all the control parameters used for its manufacture are restored, but the string is hidden when the report is displayed in Excel.

  The problem is that the binary string flattened uses tabs and returns as part of its syntax the Spreadsheet File this VI to Write it's going in all directions. Worse yet, I can't unflatten chain when I open the file text because of "corrupt data or unexpected".

  If I concatenate the string flattened with quotes around it she is superb and is placed in a single cell in Excel, but when I open the file in LabVIEW that she is still several elements in the array. I've isolated the binary string using the file VI text reading and got a subset of the quoted string, but it still unflatten correctly.

  Essentially, I need to know how to get LabVIEW to pull a string literal full of special characters into a spreadsheet file and it unflatten. Any gurus what help you can provide is greatly appreciated.

  Thank you

  I suggest that you change the formatting of your chain shipped by replacing the tabs and returns with other characters that are not considered as commands by the spreadsheet functions. Without knowing how you represent your control binary values, I can't offer specific characters.

  If two non-printable characters exist which do not appear in the control data, it's easy: just find and replace tabs and returns with those characters.  If there is no character, then something more complex needs to be done for example to escape special characters.  Or create two subVIs - one to remove the tabs and returns before writing the string in the file and the other to restore after reading.

• 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.

  Hi weitong,.

  By default, Excel expect point comma as delimiter in csv files. Change your constant from tab to a semicolon and everything goes well...

  Or open the file using the dialog box import Excel and tab as a delimiter in step 1 of the wizard.

  I am currently using create a file (path of the unwired file) so that the user can enter the name of the file "test.txt" to create the txt file. No problem here.

• day: hour: min:second of logging in a writing on a spreadsheet file

  I need to write a timestamp date time format: day: min:second (25:13:23:56) in a spreadsheet file.   Ideally using the output of ' string of Format Date/time ' and enter a 'table to build' there it goes into writing to the worksheet.  The only reason why it's required format is because I already have a program of scientific data logging 10metres upward and running.  It uses the timestamp of a Datetime.vi who takes the form of integer 132356.

  Thanks in advance for your help

  
  

• 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.
