• How to read a text file with line breaks

  Hello

  I'm reading a text file in a textFrame.  We read in, but does not include line breaks is just a big long line of text.  I use the following code to read the file.  I tried to insert a \n character after each readln() but that has not helped.  I also tried to create a variable that the readln() was crammed in before setting the textFrame.contents variable, but which does not work either. I'm puzzled. Any help would be appreciated, thanks.

  While (! notesDoc.eof) {}

  noteTextRef.contents += notesDoc.readln ();
  }

• How to read a text file that is longer than 65536 lines and write the data to a spreadsheet Excel and the data to write in a new column, once exhausted 65536 cells in a column?

  I have data to the basic generic text file format that must be converted into Excel spreadsheet format.  The data are much longer than 65536 rows and in my code, I was not able to find a way to see the data in the next column.  Currently, the conversion is done manually and generates an Excel file which has a total of 30-40 complete columns of data.  Any suggestions would be greatly appreciated.

  Thank you

• How can I read only text files in a directory.

  I wrote a program to play the files in a directory, but I want to let him read the text files from the directory.

  String target_dir = "C:\\files";

  File dir = new File (target_dir);

  File files [] = dir.listFiles ();

  System.out.println (Line);

  }

  } {Finally

  If (inputStream! = null) {}

  inputStream.close ();

  }

  }

  }

  }

  }

  }

  You mentioned you want to only read text files.

  If you are referring to a specific set of extensions, you can filter on this basis.

  ex: you want to only read .txt files, you can add an if condition as below:

            if(textfiles.getName().endsWith(".txt")) {
                // Add your code here
            }
  

  See you soon

• How to read the txt file that has words in between?

  Hi all

  I'm using Labview 8.2.

  I would like to read a text file.  I have given (after whenever he was on average more than 100 waveforms) several times recorded on the file.  The idea is to further improve the SNR in post processing by averaging once again the data (which was on average about 100 wave forms).

  I can get LabView to save the data in the file several times, then it keeps joins.

  The problem is to read data from labview, so I can on average now again.  The problem is the labview separates data sets with the following:

  "Channel 1".
  9925 samples
  Date 28/10/2008
  Time 17:16:11.638363
  X_Dimension time
  X 0 - 3.0125000000000013E - 3
  Delta_X 2.500000E - 6
  "End_of_Header."

  Then when I read it, he sees only the first set of data.

  Can someone tell me please how to read all the datasets under labview?

  I am attaching the file I want to read 'acquiredwaveform.txt' and the VI base (really basic btw) to play the file.

  Thank you

  This seems to be a standard LVM-file.  You can read segments of different data using the VI Express LVM loop (make sure that the file retains its extension .lvm).  I modified your example to show this.

  Note that my example is quite inefficient. Table of primitive construction causes a massive memory copy whenever it is used, and you would be probably better on average that you read in.  I made this way to make it more obvious how read segments of a file LVM.  In the process, I noticed that you have a good amount of phase jitter (zoom in on the graph of all the three waveforms).  With an average simple will make you smear on your waveforms.  You can either fix the problem in hardware (recommended) or phase shift your data so it lines up before on average.  If you need help with it, let us know.

• Read a text file in a cod

  I'm sure this must be quite easily, but can someone please tell me how I can read a text file, I want to display as a resource?

  There are methods available for playback of image files, but I have never attempts to read a text file...

  Thank you

  The same as any other file. The most important thing is to get an input stream. After that, you can for example read as bytes and create a string of. It really depends on the content.

  InputStream input is Class.forName("yourClass").getResourceAsStream ("resource_file_name");.

  Then something like:

  data from Byte [] = new ubyte [4096]; or the actual size of the stream
  int len = 0;
  Len = input.read (data);
  If (len == 0)
  {
  System.out.println ("empty folder");
  return;
  }
                 
  Dim str As String = new String (data, 0, len);

  Of course, it's just sort of pseudocode.

• How to save the text file input array

  Hello, I am very new to LabVIEW, so apologies if I use the wrong terminology.

  I did a VI which reads 25 text files from a 3D array.  When I click on run I need to select the files 25 text.  Is there a way I can save the data imported for later calculations without having to select the files each time?

  Here's what I have:

  Thanks for that.  But the user will not have access to these files during execution of the VI.  There are many other paintings that I'll need to save and index for other variables as well, so just for that would use the method of you would be useful to know.  All I really need is a way to save these relatively few values in a table.

  So do you intend to have these values hard-coded into your executable?  This seems dangerous and likely to have you to make updates much.  Believe me when I say you want to have the sitting files with the executable.

  But if you're insistent on this, I would use a global variable.  Have a VI just read all files and build the table for you and write in the global variable.  Then you can right-click on the control on the Panel before global variable 'Create default value'.  Save the variable and build your executable file.

• Not able to read the text file several times - Bug?

  I open the Refnum to a text file by starting my software and I'll keep the file open until the software works. I read a text file when an event occurs. The problem that I'm facing here is when I read that the file 1st time Lily can't read the text of the file but when I read it to get even empty string only. Could someone help me understand why this happens.

  

  A race condition?  What's with the two readings at the same time?  Keep the opened file is not a problem, but remember that there is a file pointer.  If you read empty strings, it's probably because you're at the end of the file.  Use Set leader VI to set Position is for the beginning of the file.

• Read a text file

  I have hopefully a quick question.

  Why doesn't the reading of text file in this example?

  Thank you

  

  When you write to a text file, LabVIEW keep a pointer with the reference so that you have the file open. So after you write 'test' in the file, your new pointer is now at location 4. When you read on, it reads pointer 4 and on.

  Use the function set the file Position in the palette advanced to read the 0 position.

• How to erase a text file...

  Hi all...

  I wud would like to know how to delete a text file...

  Am currently replacing the text file and writing... In fact, I need to open the file (after erasing the content) and write.

  I think that replace the file every time is not a good idea...

  So please let me know how to delete the text file.

  Thanks in advance.

  You can set the file size to zero using "Set File Size" in the palette of advanced file i/o.

• testimonial widget that reads the text file

  Is there someone who makes a testimonial widget that can read a text file? I am considering this is a block for customer testimonials that can read a file of say 50 different clients we wil cut and paste from various places, so that there is always a fresh review illustrated.

  Themes of Muse has some text widgets: one as a ticker-tape driveand displays a (small) number of citations. But none will allow you to modify a file of text outside the Muse of let's say 50 paragraphs and read on the page, one by one, in order.

  There are a lot of scripts to do exactly what you want, like this: alternating Message text box . JavaScriptSource, and many others, just Google: "alternating rotation script of text message". But are you able to manage scripts and HTML codes in Muse ? Maybe some useful script Wizard can cook a place for you or modify an existing one, provide you a text template file and help hair and be implemented in Muse page.

  Don't let them not to edit your output !

  Ask them to help you with a method to ensure within the Muse:

  1. adds a style and script in the header of page (see Page Properties)

  2 Insert the HTML code on the page (under the object menu)

  3 attach the text file on the site (hyperlink, link to the file)

  So, you can change the text file and download all changes with Muse.

  Hope this helps?
