• Error 1: Write to text file

  Hello. I get an "error 1 write to text file" in my program.

  The error occurs occasionally and I can't understand what is causing the error. What is this error? If I ignore it and press to continue the program seems to work and it stores data. The program acquires the data and records to several files. The screenshot of the error is attached.

  Thanks for the help

  I got it. I added a variable additionl to start recording only after that the name references were initilized. It was the problem of race condition, but now I know more about the labview data flow

• Writes a text file from a network computer to another computer on the network.

  It is possible to write a text file from a computer on the network to another computer on the network through labview without using FTP?

  Hi bebo_lm,

  It depends on how they are connected. If you have a 'normal' access to the pc and you can write on a hard drive of the other computer, you can use the writing functions of files or the copy of the file. If they are not connected like this, then you need another service. Why you do not use FTP?

• How to write the text file in Shockwave?

  Someone knows how to write the text file in Shockwave on the disc of the user?
  
  Thanks in advance.

  These Xtras can cause a lot of havoc when used with the intent to hurt.
  What you can do is to write with setpref and store a list of backups and the
  registers itself separately. Next, you need to build your own save/open
  dialog box for the user:
  * Choose a previously saved file to load or replace
  to create a user type the name of a new file to be saved.

  The only thing that remains is that the user can't decide where files
  are saved.

• FrameScript: write to text file

  Hello comrades,.

  When I have to loop through a list of files of the book and write their names in the console of FM, the full list is displayed. However, when I write the list in a text file, 1 file name is written. No idea why?

  ForEach (BookComponent) In (vCurrentBook) LoopVar (v_File) loop

  ...

  Write v_File Console;

  vs. :

  Set vPath = v_UserPath + DIRSEP + "_" 'Test' + ".txt";

  New text file File (vPath) NewVar (vFile_Listing);

  Write Object (vFile_Listing) v_File;

  EndLoop

  Thanks in advance for your comments!

  Roman

  Hi Roman, it works for me:

  The value of sPath = "C:\DATA\Test.txt";

  New file text File (sPath) NewVar (represented);

  Set oBook = ActiveBook;

  ForEach (BookComponent) In (oBook) LoopVar (oBookComp) loop

  Write Object (represented) oBookComp.Name;

  EndLoop

  Close the file text Object (represented);

  You must close the text file when you are finished with it. Maybe that's the problem with your code.

• Dynamic text from the text file problem

  Go step by step to get my data from MYSQL/php... for now, I'm stuck and cannt even get it from a text file I do worng!

  This is the code I use:

  var myLoader:URLLoader = new URLLoader()

  myLoader.dataFormat = pouvez

  myLoader.load (new URLRequest ("trees.txt"))

  myLoader.addEventListener (Event.COMPLETE, onDataLoad)

  function onDataLoad(evt:Event) {}

  for (var i: uint = 0; i < evt.target.data.cant; i ++) {}

  This ["tcname_" + i] .text = evt.target.data ["tcname_" + i]

  }

  }

  My trees.txt file contains the following:

  Plum = tcname_0 & tcname_1 = olive

  I made this as well:

  & tcname_0 = Asian plum & tcname_1 = Amazon lily &

  I have already created a few instances of dynamic text from tcname_0 up to tcname_5

  I tried with having the text in dynamic text or leave it empt anyway... nothing is read from the text file, what I am doing wrong?

  In your trees.text file, you neglected to include the variable of cant, so the loop has an undefined value to life...

  Plum = tcname_0 & tcname_1 = olive & cant = 2

• How to read and write a text file to the folder of the user preferences?

  I'm trying to code for the user to record the plug-in, the first time that the user opens Acrobat after you have installed the plug-in. I want to write a file of registration of preference of the user folder access later to check that they are already registered.

  Is there an easy way to do this? I wrote the code to access the preference of the user folder to search for the file, but I have not been able to code for the write file. All I've found is how to write a PDF file.

  Any suggestions?

• write a text file on Simulator 9800

  I'm writing a log for my application file. I used both FileConnection and openDataOutputStream, as shown in the code snippet bellow. In both cases, I can IOException with the message "file system error (1003). The interesting part is that I am able to open the file for reading well. The file is located in the res folder in my project. I use the path \logs\myfilename for playback using getResourceAsStream (path) and it works fine. But openinig it for writing and update fails. Here's the code snippet I "ve used in the entry:"

  String NomFichierJournal = logs/myfilename"."

  String outputfilename = "file:///" + logfilename;
  fconn = (FileConnection) Connector.open (outputfilename, Connector.READ_WRITE);
  OS = Connector.openDataOutputStream (outputfilename);

  The lineis commented on the second method I used. I have two cases, she out exceptions. For reading, I use just the relative path "/ logs/myfilename ' and it works. But it does not work for writing and forums it seems that I had to add the "file:///" which I did, but to no avail. I think there must be a setting I'm missing in the Simulator. I'm really working in the dark regarding the structure of the file on a blackberry Simulator system. A simple example of application is required to read and write to the local file system. It is the most popular activity, I guess that would do any nontrivial blackberry application.

  Thus, any response expertise on this subject will be much appreciated.

  I think you're a little confused about the BlackBerry file system structure.

  Try to browse the root directory and list the names of the directories you will find.

  Once you do this, you will get a better understanding of the file system.

  What I meant by SDCard/store is adding SDCard or store after file:///.

• Write to text file - question

  How can I add on top of file .txt 'caption', for example I want in my example add "date" and "time".

  Date time

  All you had to do is put in the header before the loop. It is here, but it's in LabView 2009. Tell me if this does not work on yours.

• Write continuously measure file problems

  I'm a new user of labview, so forgive me if it's simple, and do your best to not to judge my program because it is a work in progress. I tried to create an acquisition of data using a controlled box of activex and the complexity of a single loop slowed down so much that it doesn't work properly. I changed a loop of consumers/producers now, but when I try to start logging, it connects everything first and will not continue record all instances more unless I keep the enqueue switch. I do something wrong or is there a better way to do it?

  Your VI shows that you need the "enqueue element" button lit in order to the data in the queue to your consumer loop.  It is set to 'switch' action instead of "closure", which means it will remain lit once pressed until what you press it again to turn if off.

  But I think the problem you encounter, it's that you have a structure of the event in the same loop that has no timeout on it.  Event structure is sitting there waiting until that event occurs, then it lets you iterate, the loop can come back to wait on the structure of the event.  Events that are recorded in the event structure are stop, change the value;  Start logging, change the value; and the change in the value of several of your digital controls.  So unless one of these events occurs, your producer loop will keep a break.  I would recommend either a value of timeout on the structure of the event, or displacement of the structure of the event out of the loop and put in its own loop 'user interface '.

• Write in the text file on request

  Hello

  I've been struggling with the "write to text file" in the part of the attached .vi button

  I want to be able to say my program when I press on the Boolean key it should collect 1 sample point only from the mean.vi - now that I managed to do a Boolean-button that starts the collection of data and then I have to press the button again when I 'think' now, I collected a data point using the structure of the case.

  Can someone help me to collect the data a not that when I press the Boolean?

  Thank you!

• Write to the file text File.vi out all but first line begins with tab

  The PNG attached shows the code used to accumulate strings concatenated into an array of strings for the first four lines, then to a string in the array to the worksheet String.vi and, finally, use write to Text File.vi the lower right corner shows the result in a spreadsheet. Note the 3 empty entries marked by a filled red rectangle. Examination of hidden characters shows that there is a tab at the beginning of lines 2, 3 and 4. There is no tab shown in the code. How these tabs to get? How can I stop them? I tried with the option 'Convert EOL' on and outside, without any difference. The help says that an EOL OS-dependent character is added to each line. I can't imagine that the EOL Windows character has a tab.

  The tabs are from the table to the string of worksheet function.  You build a chain of worksheet, complete with tabs and CR.  Just drag a concatenate the strings in his place and it will work.

  I would bag all constants of the tab and the CR.  Build an array of 2D with just the values strings (without tab, no CRs), happening in the array to function SS.

• How to put more than 100 acquisitions to "write text file.vi?

  Hello

  I work with labview for about a week and I need help.

  I use the "write to text file.vi" in one of my screws and now I've discovered, that the number of acquisitions in this VI seems to be limited to 100.
  but I need a larger number (around 10,000). So I need to know how to increase the number.

  If you need more information, tell me and I've got the poster!

  Your database server is likely to be Unix or Linux, right? Which means that it uses a single character (LF) to "new line", rather than Windows that use two characters (CR - LF) to 'new line '.
  (If you open your file with WordPad instead of NotePad it will probably look OK.)

  UTL_FILE. Put_line uses as a "new line" everything that uses the o/s database server.

  So if you want to write a file to be used specifically in Windows, you can make your own "new line" rather than using the servers.
  Use PUT rather than PUT_LINE and simply add the two characters that Windows uses to "new line":

  UTL_FILE.PUT(F,
                    I.1||'|'||
                    I.2||'|'||
                    I.3||'|'||
                    I.4||'|'||
                    I.5|| CHR(13) || CHR(10) );
