Header / data in the spreadsheet file

• Writing data in the text file or excel spreadsheet

  Hello

  I have a silly question to ask questions about the writing of data in a text file or a spreadsheet. I have an example that simulates a sine-swept DAQmx. The output it provides is the (amplitude and phase) frequency response function that is plotted on a graph (see VI) attached. I like to use these data for further analysis by transmitting the data to a text file or a spreadsheet. I've tried a few things, but the thread is broken. I guess I use the sink badly - so I was wondering, can you please advise me on what sink should I use?

  Your help would be very appreciated,

  Thank you very much

  The wire is broken, because you cannot connect this type of data to one of these two functions. The data source type is a table 1 d of the clusters, where each cluster contains two tables. The text file write accepts strings, not clusters. Writing on a file action accepts dynamic data, and while you can convert dynamic data tables, there is no built-in mechanism to convert a table 1 d of the clusters of two matrices.

  What you need to do is to convert the data in a format which can be accepted by these functions. Since you want to have a "spreadsheet" file then you should use writing to the spreadsheet file that creates a delimited text file. Since the frequency data would be the same for the plot of the magnitude and phase diagrams, you can have 3 columns: frequency, amplitude, and phase. You can take off the items using Unbundle by name, and then create a table 2D of each element of the cluster. The real question is to know if you want to save the data at each iteration and if you simply add on the file. The attached figure shows write an initial header and then adding just streaming the data.

• 1059 Error - cannot get 11 channels of data written in the spreadsheet file

  Hello everyone

  Again, it's Luke. I got the 7 fixed error, missing just a specific filepath to save data too.

  I now hit another snag along the way. When I enter data into a spreadsheet box writing, an error comes up saying "error 1059: unexpected file type".

  Anyone have any idea why its doing this?

  The only things that I put in the function box is some specific data on 2 GPS units I use, with a tension from my DAQ and the installation of strain gauges. Information works on my front and information is coming through, but will not save the data in a spreadsheet file, and writes a .lvm file will not work either.

  I will surround a printscreen of the configuration for the block diagram:

  I'm not sure of the exact file extension

  How do you define it?

  You set under whatever file name you put in your control filepath.

  I don't think it makes sense to get an error that says for attempting to write to a text file.

  Any chance you try to write the file to a path that you have not the full access rights to?  I think the error may be 1059, but it's actually be caused by a file windows error.  How about some strange characters in the name of the control that are not valid in Windows file?

• 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.

• 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.

• Writing data in the CSV file?

  I tried, but in vain, to write data in the CSV file, with the column headers of the file labeled appropriately to each channel as we do in LabView (see attached CSV).  I know that developers should do this same in .net.  Can anyone provide a snippet of code to help me get started?  In addition, maybe there is a completely different way to do the same thing instead of writing directly to the CSV file?  (In fact, I really need to fill a table with data and who join the CSV every seconds of couple).  I have the tables already coded for each channel, but I'm still stuck on how to get it in the CSV file.  I'm coding in VB.net using Visual Studio 2012, Measurement Studio 2013 Standard.  Any help would be greatly appreciated.  Thank you.

• 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.

• Modification date in the jpg file properties menu

  My Nikon image download went well, but 4 of the images have the wrong date on them when they were taken.  I think it was off on the camera somehow.  So, when I view it in the Microsoft folder, they are out of use.  Is there a way to change the property case created date on some images in the large folder?

  To change the dates of file or folder, you will need a 3rd party program as freeware "Attribute Changer.
      <>http://www.Softpedia.com/get/system/file-management/attribute-changer.shtml >

  Remember that sometimes the dates of the .jpg files come the EXIF information stored in the .jpg file and you may need some kind of an EXIF Editor to change that.

• Tool to manage data in the DMP file

  Friends,
  
  We currently have this process:
  
  -Export production data using expdp
  -gzip .dmp file and move it via ftp to test servers
  -import data on the test servers
  
  We are trying to create a process where we can remove all the "sensitive data" test, because our data is highly confidential.
  So, we have already designed a procedure that can remove these data after the import.
  
  BUT my question is: there is some King of oracle tool which can allow us to modify the data in the dmp file, even before you start the import operation?
  
  
  Approx. (Test and Production): Oracle 10 g 2 running under Linux
  
  Thank you

  You can protect your sensitive data after importation in the test environment using datamasking grid control functions.

  Another solution, I've used sometimes is create the trigger for insertion in the test environment a sensitive but important data change is slower.

• How to share data in the swc files?

  I can save the shared data (such as dsn) in application.cfm so all cfm files can read.
  
  But how to share data in swc files as application.cfm. I heard application.cfc, may I use share data in the swc files?
  
  Don't you think that if it is correct that application.cfm and application.cfc exist in the site?
  
  Thank you
  
  Mark

  IIRC, you can't use both. If you Application.cfm and Application.cfc in the same folder, CF will ignore Application.cfm.

• How to remove header, time and date of the Subvi "export waveforms to the spreadsheet file?

  I use 'Export waveforms for spreadsheet File.vi' in order to export the labview data into a file.

  However, the default format is the following:

  waveform [0]
  T0 13/11/2009 14:54:34
  Delta t 0.001000

  time Y [0]
  2009-11-13 14:54:34 - 2.441406E - 3
  2009-11-13 14:54:34 - 2.441406E - 3
  2009-11-13 14:54:34 0.000000E 0

  Yet I am interested in only the actual data without header or stamp date and time, for example:

  -2.441406E - 3

  -2.441406E - 3

  0.000000E + 0

  Could someone help me please with the adaptation of the Subvi to my needs?

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

  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.

• How to view the data in the text file to the format column

  Hello

  I am acquiring data from an oscilloscope.

  Wen I save the data in a text file to aid wite spreadsheet string, all the displayed voltage values r first, then values of time... in addition to its delimited by tabs

  How can I view it like the r of time values in a single column and the voltyage of the r-values in the other column

  thanx

  Hello

  I don't know what is exactly the format that you found. I think you should try to use the function Array transpose (from the palette of function table) before you pass the array to write to string of spread sheet function or directly loyal to Terminal son transposes on writing worksheet function and see if you get the desired results.

  PS. : Share your code would be appreciated.

  Kind regards
