• Cannot write to the file of measure

  Hi all

  I'm acquires data from the analog input using the DAQ with Embedded controller PXI8186 Wizard of PXI6259
  I'm writing a file format xlxs using writing to express vi measure, every time I have applied no file has not been created
  I tried several files such as C:\test.xlxs and C:\Users\name\Desktop\data test\test.xlxs directory
  not yet a single file created on my host pc or PXI-8186. After that I implemented the program displays window "are you sure? Your data will not be saved to a file"and have two choices to choose Donot save or try again
  I really want to create the file on the host PC if possible help pls thanks in advance.

  Better subject.

  You try to deploy the express vi into your RT controller? You should try using the low level screw and you can use the shared variable to transfer the data to the host. The method that you try may work only when you have the card in your PC. Also, you will get only the latest data saved to your file as you write the last item coming out of the execution of the loop. Try to restructure your code and check examples of LabVIEW.

• Write to the file of measurement with a loop For using the value of the dynamic data attributes

  I looked and looked, but couldn't find a solution for this.

  I currently have 15 points of different data that I try to write in an Excel file.  I have all combined in a table and lie with the function "write into a file position.  However, the column names are always "Untitled", "Untitled 1" etc.  I then used the function 'Set the Dynamic Data attributes'; but for this I have to do 15 different functions "set data dynamic attributes.  It was suggested to use a loop with the function 'Set the Dynamic Data attributes' inside of her, but I can't find how do.

  I have several arrays consisting of 15 different values for 'Signal Index' 'Name of Signal' and 'Unit', but also a unique 'get Date/Time In Seconds' related to 'Timestamp '.  The problem is that the error I get when I try to connect the output with Scripture at the entrance to measure file:

  The source type is dynamic data table 1 d.  The type of sink is Dynamic Data.

  How can I fix it?  I have attached a picture of my installation; Sorry if this is gross (I'm new on this!).  Thank you!

  It will get rid of the error, but it is not quite correct. What you need to do after that is to click on the output or the tunnel entry and select 'replace with the shift register. In addition, the array of values that you have wired to the Signal Index is wrong. Arrays are 0 based. Just wire the iteration Terminal here. And, finally, take the size of the table and this connection to the N terminal are stupid. Don't wire nothing to this.

• Write to the file of text formatting issues

  My apologies if I touch on a topic that is discussed elsewhere.  I have two questions, which seems to be related, I'll have to overcome the difficulties.  I date of blood collection, converting it to a temperature and then writes the timestamp, temperature, voltage, and original tension to the file.  Currently, when I write these values to the date and time of the file appear on a single line, temperature and tensions appear on the next line, and then there is a space before the pattern repeats.  In addition, before data are collected I write information in a header, and if you look at the .csv file attached, you will see that the data are that all offset a column to the left.  Any ideas how I can fix this problem?  My code is probably speaks for itself, but I really am a novice, so any general idea in the non-jargon terminology will humbly accept.  Cheers, Peter.

  GEO,

  Do not build your strings in an array of strings.  An array of strings are written a / line in the function "write text to a file.

  Use the function to concatenate strings and string together a tab character between the date/time and the first value.  The "write text to file function will add its own chain of end of LIFE at the end of writing.

• Why even after having changed the permissions can't write to my files?

  I moved files on "users / shared" on the imac 27 "my father Yosemite retina.  He got last June but was not able to migrate because of her old imac was in Florida and North Carolina.  So, I migrated the old imac again with time machine backup charges a few months after getting the computer.  Now, I'm trying to merge the 'old' on the new computer account with the migrated account 'new', I restored it with time machine from the old imac.  I thought I was smart "passage" large libraries of film and photo of users / shared and that the account migrated from old imac. (on the same computer again) But I have no write permissions for files on the migrated account.  And making matters worse, while I can't write to files, I'm still able to corrupt them trying to change permissions and try to load them with i-movie and what not.  So now, I have a 6 GB corrupted movie library and not backup.  I tried it duplication and corrupt also.

  So my question would be "why is it when I add to the new migration full privileges to user for these files, I always failed to write about them?  Now instead, I wonder if there is a way I can fix the corrupted film library file.  Film - I tried and failed on the double.    I tried available i-movie file to 'all' as well as the addition of the new migrated user full privileges to it.  While I was able to do it without error (it seems to take the changes) or the new migrated user or former user on the new computer can write to the file (i-film library) at this stage.

  Every article help I read says just to click on info and change the privileges for what I did.  So I'm pulling my hair out.

  Hope that I was not too confusing in the way that I want to talk about the two different accounts.

  Reset user - file property See post by Linc Davis

  You may need to restore the permissions on your user account. To do this, start on your recovery partition (hold down the command and R during startup) and open Terminal from the Utilities menu. In the Terminal, type: 'resetpassword' (without the), press return, and then select the admin user. You do not have to reset your password. Click the icon of your Mac hard drive at the top. In the list box below, select the user account that has problems. At the bottom of the window, you will see a box labeled restore Home Directory permissions and ACLs. Click the button to reset there. The process takes a few minutes. When you're finished, restart.

• Issue of table + write to the file

  Hello, I am using USB-6009 with Labview 8.5

  I searched and passed tutorial table and still confused about acquisition of data...:)

  So here's what I'm doing (simple)

  I have two tension analog (AI0 AI1) returns through the DAQ assistant

  and I would like to follow up respectively and finally want to write them in lvm format or csv format...

  Question 1.

  Can I have an example of table VI with the DAQ assistant? all the tutorials I went on

  they are only about numbers--not the dynamic data...

  I think of... convert data into DBL and reorganize somehow to each table to the graph of the monitor

  Question 2.

  so I cut the data by using the table to display the monitor, then I will add both the value of the data in table

  to write to the file? or... is it possible to write in the file directly from the Daq Assistant, write on the file VI?

  Quesetion 3.

  If so, could you tell me how this writing on a file to save the data? 1st column with odd rank-> AI0

  1st column with the same line-> A1... something like that?

  Thanks, I spent about 3 hours of that, google them, read the help of labview and helped a lot

  1. you should be able to double-click the convert to Dynamic Data and convert the waveform in a table.

  2. just connect the output of the VI DAQmx Express write it on the Express VI of LVM.

• Quickest to write data to file

  Hi all! [This is my first post here so please be kind =]

  I am creating a data acquisition + digital output system and spin in data acquisition issues AND writing of data in a PDM file.

  -The module must divide an interval of 10 seconds in blocks of 20 500 ms. The data will be acquired during all the 10 sec interval and written to the file.

  -During the first block (block 0), a digital output is set to high

  -Based on the number of peaks detected at the entrance during blocking 0, another digital output will be so turned on during the channels meeting the condition of the art for the duration of a given number of blocks (user-defined).

  -At the end of 10 seconds, this process will be a loop

  If you look at my code, the while loop with playback function normally has a "write on a file of measure" vi in there, however, when he's here, I get the error: "tried to play back samples that are no longer available. You can fix this by increasing the size of buffer, etc.. »

  As soon as I take this writing to file out of the loop, the module works fine without error, IF I do not use a program in the background, like the Chrome (this also triggers the same mistake).

  I need this program to run at a minimum of 24 hours, so it is important that this can work for a long period of time. An idea that I thought was of buffering data and then write to file both after 10 seconds... but am not sure how to implement it. In addition, I don't know if something about the way I wrote the code kill processing power and causes this error.

  Any help is greatly appreciated!

  
  

• Add data at the beginning of the text file

  Hello

  How can I do to add the data to the top of the file instead of down as the attached VI?

• Add data in the header of a .wav file

  Hello guys,.

  I seek your help for a small problem that I can't spend during my internship.

  Here's what I want to do: I acquire signals that I write a .wav file. What I would do then is to reopen this .wav file and add data in the header, such as the sensitivity of the microphone for example. I am doing this is because it's one of our program of works, it can resume the pressure vs time signal using this information. I already have the hex code I need to add, but I was not able to determine if such a thing is possible or not after a day of research ideas would be greatly appreciated. I wonder if Matlab might do the trick but I prefer to stay with the 'normal '... screws

  Thank you very much for your help.

  To insert data into the middle of a file, you will need to rewrite the entire file after that point, as Gerd said in the linked post.  I would do the following:

  1. Search for the location you want to put your new piece
  2. Read 65 000 bytes from forward and store in a local cache (shift registers work well for this, or just a wire at this point).
  3. Write your new piece, taking note of how long it is
  4. Give your data buffered less the length of your new song
  5. Read a 65 000 other bytes and put it in a new buffer
  6. Write the end of the old buffer and a part of the new buffer until you get to 65 000 bytes
  7. Repeat 4 to 6 until you reach the end of the file
  8. Update the offsets in the header to match the new locations of piece, since you have moved things

  You can probably do it with both data pads in a pair of registers at offset in a loop.  The 65 000 bytes is chosen for best performance.  You can use other sizes, but your speed can suffer.  Let us know if you encounter any problems.

• collect the data to write to the file

  Hello everyone!

  I was wrong of wich pretty depressing problem my mind... for a few days. I have a VI with while the witch loop is part of the largest project... my goal is to collect data and save them to file after 1000 while loop activities... be more specific - after all done loop 1000 moves I want to write to the file, the number of strokes (in the 'Number' of an attachment photo) and the result of the value ('table') should be a kind of table (2columns 1000 lines)... I can't do more while ower loop all the VI because it allows the other VI to work... Can you suggest me sommething?

  .. .to while say you the activities of the do loop iterations?...

  Yes, it's wright, I couldn't find the wright expressin at the end of the night.

  OK I will try to write to the table line by line... I'll check up is it posible to add to an existing spradsheet of the file a line of data for 1000 times after each iteration of the loop... it might be more reliable because each iteration of the loop is device once in a 30 min, and if your PC loses power I lose all data.

  Thank you so much for the ideas!

• Rules - write to the file how each Const mean?

  I have a subroutine in my rules to write to the file.
  
  It contains a line indicating: Const ForReading = 1, ForWriting = 2, ForAppending = 8
  
  What do each of them?
  
  To write?
  Read?
  Add?
  
  I used to use Add, but he seemed to be putting items duplicated in the file everytime I ran it.
  
  Then, I tried writing and he gave me a single record.
  
  Thank you!
  
  
  
  
  Here are all of the subroutine:
  
  Void WriteToFile (txtStringToWrite, FName)
  On Error Resume Next
  Const ForReading = 1, ForWriting = 2, ForAppending = 8
  Dim fso, f
  Set fso = CreateObject ("Scripting.FileSystemObject")
  The value of f = fso. OpenTextFile ("C:\Hyperion\Extracts\" & FName, ForAppending, True)
  f.WriteLine txtStringToWrite
  f.Close
  On Error GoTo 0
  End Sub ' WriteToFile

  By adding the means adding the same file - the number of times you run the rule he adds in the same file.
  Write clearly means the first file and the wirte.

• error: could not write the destination file (1 003)

  I am trying to export 40 photos of Photos.  I just installed OX El Capitan.  Only 13 of them get downloadable.  For the rest, I get this message: error: could not write the destination file (1 003)

  I tried to manually fix the library but still does not work (command + option + opening photos).

  And I do not have a backup on icloud photo library I have a backup on an external drive...

  You try to export the originals of your photos or revised versions?

  When you try to export photos to?

  You try to export to a folder on your system drive or a folder on an external drive?  If an external drive, which is the file system? And how the player is connected?

  You have permissions to write to the folder, when you export to?

• message cannot write to the file destination 1016

  I try to export photos to a memory card and I get a message "cannot write to the file destination 1016. I was able to export several photos, then I could not export more. Help

  In general, memory cards are in FAT format that hold a number very limited file to the root - the safe way to put photos on a memory card is select them in Photos and export to a folder on the desktop and then use the finder to drag this file to Gendarmerie, unlocked memory card
