• Add data at the end of a specific line in the text file

  Hello

  I'm trying to add data at the end of the last 4 lines of the text file attached with the ' table to add.  4 rows (422.5800 entry), I would add the first entry of the 'Array to add' entry, on the 5th line to add the second entry of the 'Add picture' and so on.  How can I do this?

  Any help will be appreciated.

  Sincerely,.

  hiNi.

  After re-reading your post, I think that's what you really want to start adding after the first 4 rows.

• Need help: UTL_FILE read and write in the text file

  Hello, I'm on version 11 GR 2 by using the UTL_FILE function to read a text file and then write the lines where it starts with the word "foo" and put an end to my writing in the text file where the line with the word "ZEN". Now I have several lines that begin with 'foo' and 'ZEN' allow a paragraph, and in this paragraph, there is a line that begins with "DE4.2". Therefore,.
  I need to write all of the paragraphs that include the "DE4.2" line in their beginning and end of lines 'foo' and 'ZEN '.
  
  FOR EXAMPLE:
  
  FOO/234E53LLID
  IT'S MY SECOND LINE
  IT'S MY THIRD LINE
  DE4.2 IT OF MY FOURTH LINE
  IT'S MY FIFTH LINE
  ZEN/DING3434343
  
  FOO/234E53LLID
  IT'S MY SECOND LINE
  IT'S MY THIRD LINE
  IT'S MY FIFTH LINE
  ZEN/DING3434343
  
  I'm only interested in writing the first paragraph tha includes line DE4.2 in one of the paragraph of lines not the second ther that does not include the "DE4.2".
  
  Here is my code so far:
  
  CREATE OR REPLACE PROCEDURE my_app2 IS
  Utl_file.file_type INFILE;
  outfile utl_file.file_type;
  buffer VARCHAR2 (30000);
  b_paragraph_started BOOLEAN: = FALSE; -flag to indicate which required paragraph is started
  
  BEGIN
  -Open a file to read
  INFILE: = utl_file.fopen ('TEST_DIR', 'mytst.txt', 'r');
  -Opens a file for writing
  outfile: = utl_file.fopen ('TEST_DIR', "Out.txt", "w");
  
  -Check the file is open
  IF utl_file.is_open (infile)
  THEN
  -lines in the file in loop
  LOOP
  BEGIN
  UTL_FILE.get_line (infile, buffer);
  APPLICATION STARTING POINT-
  Buffer IF LIKE 'foo %' THEN
  b_paragraph_started: = TRUE;
  END IF;
  -SEARCH FOR GRADS APPS
  IF b_paragraph_started AND buffering LIKE '% 4% ' THEN
  UTL_FILE.put_line (outfile, buffer, FALSE);
  END IF;
  -REQUEST FOR ENDPOINT
  Buffer IF LIKE '% ZEN' THEN
  b_paragraph_started: = FALSE;
  END IF;
  UTL_FILE.fflush (outfile);
  
  EXCEPTION
  WHEN no_data_found THEN
  EXIT;
  END;
  END LOOP;
  END IF;
  UTL_FILE.fclose (INFILE);
  UTL_FILE.fclose (outfile);
  EXCEPTION
  WHILE OTHERS THEN
  raise_application_error ("-20099, ' UTL_FILE unknown error");
  END my_app2;
  /
  
  When I run this code I get only one line: DE4.2 it ME LACK THE WHOLE PARAGRAPH
  
  PLEASE ADVISE...

  I agree with reservations of Justin on the length of a "paragraph" and the number of users that are running at the same time, so here is a version without the collections.

  CREATE or replace PROCEDURE my_app2 IS
     infile utl_file.file_type;
     outfile utl_file.file_type;
     buffer VARCHAR2(30000);
     b_paragraph_started BOOLEAN := FALSE; -- flag to indicate that required paragraph is started
     b_toprint BOOLEAN := FALSE;
     l_para_start pls_integer;  -- start of "paragraph"
  BEGIN
     infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r');
     outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w');
     LOOP
        BEGIN
           utl_file.get_line(infile, buffer);
           IF buffer LIKE 'FOO%' THEN
              b_paragraph_started := TRUE;
              l_para_start := UTL_FILE.FGETPOS(infile) - (length(buffer) + 1);
           END IF;
           IF b_paragraph_started and buffer like '%DE4%' THEN
              b_toprint := TRUE;
           END IF;
           If buffer like 'ZEN%' THEN
              IF b_toprint THEN
                 UTL_FILE.FSEEK(infile, l_para_start);
                 utl_file.get_line(infile, buffer);
                 while buffer not like 'ZEN%' loop
                    utl_file.put_line(outfile,buffer, FALSE);
                    utl_file.get_line(infile, buffer);
                 end loop;

  You may need to change the length (buffer) + 1 depending on your platform and if you want a blank line s NLE out paragraphs, add another call to put_line after that outside of the loop in the fi l_toprint block.

• Problem with end of line in the text file.

  Using LabVIEW 2010 on W7 64 bit in the USA.

  I have an application in which I write in a text file.  I use the function "Write to a text file" to write the text and "Reading a text file" function to read again.  My problem is with the end of line character.  The text that I write is a long chain, not an array of strings.  While building this chain, I insert the constant EOL of the palette of channels function to indicate that a new line is planned.  My tests showed this EOL constant values of consecutive bytes 13 and 10.  After writing all the text in a file, I can open the file with Notepad, or Word, or something else, and it is displayed correctly.  When I read he returned with the function of text file reading, I'm trying to parse the string by searching for the same constant EOL, but it does not work.  A closer examination of the extracted string from the file reveals that the value of end of LIFE has changed for only 10.  The location of the byte to 13 disappeared.  I know there is a note on the writing of the function of text file add/change the EOL characters, which are the default values of the system, but the note specific tables.  I manually put the value in the string.  Does anyone know why this happens and how to fix it?

  Thank you.

  The help of reading from text file function

  The function converts all characters in end of line break characters online platform, dependent unless you right-click the function and remove the check mark next to the menu item Convert EOL .

  Right-click your reading and uncheck the EOL conversion.  I recommend to do the same thing to your writing to text file feature.

• How to concatenate strings with the lines of a text file

  Hello
  I tried concatenate strings with the lines of a text file, but something is wrong with my code and I belive is the agruments I use in the cycle for. If anyone can help me I will appreciate it very much.
  My code is:
  [code]@echo off
  the value "input=C:\Users\123\Desktop\List.txt".
  for /f "usebackq tokens = *" % in (' input % ') do)
  the value 'str1 = C:\some directory\ ".
  the value ' str2 = %% ~ F '.
  the value "str3 = .pdf".
  the value "str4 = str1% str2% str3%.
  echo.%STR4%
  ) [/ code]
  and the text file is something like:
  121122 [code]
  122233
  123344
  124455 [/ code]
  But I get only one wrong answer and I have to run it like 3 times to get a real result and it is a mistake, the first two are empty spaces and gives the third one as the last line of the text file but repeated n times, where n is the number of lines in the text file.
  Result:
  [code] C:\Users\123\Desktop>concatenate.bat
  C:\Users\123\Desktop>concatenate.bat
  C:\Users\123\Desktop>concatenate.bat
  C:\some directory\124455.pdf
  C:\some directory\124455.pdf
  C:\some directory\124455.pdf
  C:\some directory\124455.pdf
  C:\some directory\124455.pdf
  C:\Users\123\Desktop>[/code]
  So if anyone has an idea about what is wrong please let me know.

• 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?

• Adobe Reader highlight tool is more full of text, simply create a line around the text

  The highlight in Adobe reader tool no longer works as before.  Instead of filling the text, as it is used, the tool creates just a line around the text.  This makes it much harder to identify strengths.

  I am running Win 8 and using Adobe Reader XI version 11.0.09.

  I have attached a screenshot to illustrate.  The way the tool used to work, they testify as I want it, highlight all the text in the document.  As it is it currently works, is shown on the first line of the text, where a part of the text was highlighted with the tool as it works now.  I have just created a yellow line around the text.

  I checked how the highlight settings are both the former highlight text and the new text, and they look identical.  Percentage of the color settings and opacity are the same.

  

  Very frustrated.  Any help appreciated.

  Try to run a repair from Acrobat (via the Help menu) installation.

• Odd number of columns in the text file

  Hello everyone

  From an Excel (.xls) file, I saved (tabs-delimited text) file and open in Labview. The file has only 2 columns (apparently), but my VI says he has 12! I tried to find any character 'lost' in the file but it's all in the first two columns.

  However, if I open the .xls file, save the text file delimited tab, open this tab delimited text file using excel, hit save and then open in my VI, the VI will tell me that the file has only 2 columns. Strange.

  Enclosed please find my VI (I tried two different methods to load the file and got the same results).

  Hi Ali Afzal,.

  I think that the attached example can work for you. If not, then try the solution with sending the data to a parallel running the loop and store it there.

• Playback/record to the text files using HTML5 as a basis for the code

  Hi, I'm new and I did some research and I found a variety of solutions that seemed a little more complicated than I want. I would like someone to direct me to something that could teach me how to do two things.

  (1) read the text files (essentially my difficulty is how to interact with the file system of playbook for reading files and how to save text files with output 2).

  It is not necessary to try and catch.

  Thanks in advance!

• 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 write to several lines in the text element?

  I tried to write 2 lines in the text element, however only return one row:

  Try this:
