• The monitoring of test data to write in the CSV file

  Hi, I'm new to Labview. I have a state machine in my front that runs a series of tests. Every time I update the lights on the Panel with the State. My question is, how is the best way to follow the test data my indicators are loaded with during the test, as well as at the end of the test I can group test data in a cluster, and send it to an another VI to write my CSV file. I already have a VI who writes the CSV file, but the problem is followed by data with my indicators. It would be nice if you could just the data stored in the indicators, but I realize there is no exit node =) any ideas on the best painless approach to this?

  Thank you, Rob

  Yes, that's exactly what typedef are to:

  Right-click on your control and select make typedef.

  A new window will open with only your control inside. You can register this control and then use it everywhere. When you modify the typedef, all controls of this type will change also.

  Basically, you create your own type as 'U8 numéric', 'boolean', or 'chain' except yours can be the 'cluster of all data on my front panel' type, "all the action my state machine can do," etc...

• 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.

• Write to the file in Question Spreasheet

  Hi guys. In fact, I have a few questions about the most effective way to do a number of things. This VI aims to collect a tension all the seconds so as determined by the user and then draw the voltage vs the time it was taken. I also want to save all these in a text file.

  Currently, it works pretty well, but I don't know if graphs of my functions as I have (drop voltage and time values in a table and using Graph xy generation with the berries as inputs) are the best way to do it. Because I take only data each max ~ 5 seconds table size will never become a problem? I could run the program for a period of ~ 24 hours is 17280 values in the table at the end of the day.

  I am also having a problem with the way in which the values are stored in the spreadsheet file. How I put it in place now values are added to the current file that is not a problem. However they are not separated by anything when I open the txt file, whether they are in the same column. I know I put something inbetween them such as a tab or comma for excellent to put them in different columns. What is the best way to do with the numbers? Above all, I converted the concatenated strings then a tab/comma at the end of the data point, then get it converted to a number, but it seems that there must be an easier way to do it.

  Other comments randomly on the rationalization etc. my code is appreciated

  Thank you!

  The approach of the producer consumer, I'm guessing that I would simply put the DAQ assistant in its own sequence that takes a point of data every x seconds while the representation graph/writing/etc is it's own loop. Looks like a much more viable approach.

  I wasn't suggesting to the DAQ assistant in its own sequence. Architecture of producer-consumer, the consumer is usually (but not always) a state machine. The state machine gives you much more flexibility than a rigid sequence structure.

  Thanks for the comments smercurio!

  One last thing I wasn't very clear on the problem of delimitter. In fact, I want to insert a delimiter inbetween two tables, not just after them. So, right now, they are put into a single set. Time of tension then below it. I want a delimiter between the voltage and time so that when the file opens tension appears in a column and time appears in the next. While the file drop down a row and repeat the tension. Time. So I think I still need a way to add something to the tension or maybe insert an ascii value between them that will work as a delimmiter?

  Your problem is performing connections to the entry of table 1 d to write it in the spreadsheet file. I had spotted this when you first look at your VI. Table to build that creates the array for writing to a file in spreadsheet should have the opportunity to 'Concatenate entries"not controlled, and you should feed data to the entry in table 2D writing worksheet function.

• 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!

• Extract PDF form data using JavaScript and write in the CSV file

  I received a PDF file with a form.  The form is * not * formatted as a table.  My requirement is to extract form field values and write into a CSV file that can be imported into Excel.  I tried using the menu item "Merge data from spreadsheet files" automated in Acrobat Pro, but the release includes both the labels and values.  I'm mostly just interested in the form field values.

  I would use JavaScript to extract the data from the form and learn JavaScript write CSV file (since I know what should look like the spreadsheet of end).  I got regarding the extraction of the fields in the form:

  this.getField("Today_s_Date").value;

  And the rest of this post: http://StackOverflow.com/questions/17422514/how-to-write-a-text-file-in-Acrobat-JavaScript , I tried to write to CSV using:

  var cMyC = "abc";

  var doc = this.createDataObject ({cName: "test.txt", cValue: cMyC});

  but I get the following error:

  "SyntaxError: syntax error".

  1:Console:Exec ".

  Ideally, I don't want to use a third-party tool online to make, because the data are sensitive.  But please let me know if you have any suggestions.  The ideal output is a CSV file that an end business user can open in Excel to see the format of spreadsheet of his choice.

  Did anyone done this before?  Open to hearing alternatives as well.  Thanks in advance!

  The code you have posted works fine for me in the JavaScript console, so I suspect the problem is something else. Where did he put the code and y at - he seized another code?

  In addition, if CSV is not a strong requirement, I would say that you use delimited by tabs instead. Fields normally cannot contain tab characters, this is a good qualifier to use. It will be also more reliable when you import in Excel. If you need to process the field data that may contain quotes, you need prepare correctly the string data and can use a JavaScript library like this: https://github.com/uselesscode/ucsv

• Write to the file of accounts, data from customs (intersection POV) in the rules of HFM

  Hi all
  
  I'm trying to use scripture to deposit into the HFM rules. I am able to get the entity, scenario, year, time, and Timestamp to save to a file (see code below). Is it possible I can get accounts, customs and crossing of data also to write to a file and make the analysis of perfromance? Basically, how can I have the whole POV in a log file and test the rules.
  
  f.WriteLine txtStringToWrite & '-for:-"& HS. Entity.Member & "-" & HS. Scenario.Member & "-" & HS. Year.Member & "-" & HS. Period.Member & "" & Now()
  
  Thanks in advance. Looking forward to hear from you.
  
  Chavigny.

  The account, PKI and custom dimensions are not part of the point of view that the entity, period, year, scenario and value. The only way that you can write these dimensions in a file is to call them in a table, as HS. OpenDataUnit, or list any. It is the only way to get the context for intersections.

  If you try to write data to a file, you'll end up with a file that is at least as large as the database itself and could be a very slow process. If that is your intention, you would be better to simply analyze the database. Write to a file should be used only for debugging.

• 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.

  Who helps?

• ImageSnapshot object - how to write in the file

  Hello
  I'm working on the creation of an AIR demo program that takes an image loaded into one image mxml component and take a snapshot of this image with a button, he can evolve into a thumbnail size and recorded on the local drive.
  
  I took this original code of blog.flexexamples.com, added a ByteArray (ba) and on the instantiation of the ImageSnapshot 'takeSnap' object, I've included a miniature of the scale (height and width). When I run the debugger and create a breakpoint at the end of the captureImg() function, it is said that the bytesAvailable for the takeSnap object and purpose of the ba are 0. However, the runtime, given in the text box when the event is triggered. Then. I don't know how to take the data of the ImageSnapshot and switch to a filestream. The documentation says that the jpeg encoder contains the metadata, but it does not have a method to write to the disk. Thank you. I'm really stuck!
  
  
  

  OK guys, please, I get an error at the end of the file, but I don't know if I should open the filestream first, whether it is better to catch this error when capturing the bytearray (ba). I need to write this produce. All my attempts this morning creating a corrupted file. Thank you, Jed

• 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.

• Write to the table, adding additional rows in the csv file

  Hi all

  I created a program that measure current over time.  It works well, but when I write to the spreadsheet, there are additional lines between the row of data.

  I've created a header file, which is passed into the while loop where the data entered in a table and then entered in the worksheet.  If I simply display the table, there is no additional lines, but when I open the file csv in excel, there are more lines.  I'm pretty new to labview, but everything works the way I want to (it's a simple program) apart from that.

  There is a trolley or jump back in your chain of row data.  You can get rid of that by adding a "trim whitespace" function between the function of "visa read" and "replace the subset of the table.

• Write to the file

  I am constantly writing data in 2 columns in a spreadsheet file in a loop of the consumer. I would like to topics (string format) at the top of the worksheet. I have attached an extract of my code showing what I'm doing now... I want these positions to be written to the file once and write the data in the same file under the relevant headings. However, currently my headers are written to the file with each iteration of the loop instead of writing just once.

  I tried a few different variations of my extract attached code, including by combining data and position in a table and using a write to the worksheet vi, but a similar output occurs

  I looked at the previous threads highlighting similar problems, but found nothing that helped me with my problem

  Stroke

  Move writing the header outside the loop or put it in a case statement that she writes only on the first iteration using the loop counter.
