• Reading single line of the text file

  I want to print a single line instead of the file around so I read that I need to store the contents of the file into an array and then get the index of the line. Problem is that I couldn't find any information on how to do it. Can someone give me a shot. Thanks in advance.

  This isn't a problem with encoding. You just need to do a little extra accounting and adjust start and end indices to remove these characters. To treat the "\r\n" of line termination style, you can maintain a flag (initially false) to indicate that the previous line ended with a \r; If a line begins with \n, it should be treated as the end of a line (empty) if the flag is true (in which case it should be ignored).

  If you want to extract all lines (not just the first), then it may be easier to do this accounting while avoiding a separate function. Something like this (untested):

  // read the file into a byte array 'data'; then:
  Vector lines = new Vector();
  boolean endCR = false;
  int start = 0;
  for (i = start; i < data.length; ++i) {
    if (data[i] = 0xD) {
      lines.addElement(new String(data, start, i - start));
      endCR = true;
      start = i + 1;
    } else if (data[i] = 0xA) {
      if (endCR && i == start) {
        start++;
        endCR = false;
      } else {
        lines.addElement(new String(data, start, i - start));
        start = i + 1;
      }
      endCR = false;
    }
  }
  String[] results = new String[lines.size()];
  lines.copyInto(results);

  Hello CAs,
  Welcome to the community of Sony.

  What is the model number of the digital book reader?

  The reader supports text formats (.txt) as well as the two following formats:
  -File EPUB (.epub) EPUB (version 2.0 of PAHO) taken in charge
  -PDF file (.pdf) support is based on the PDF 1.6 specification.

  The default language on your Reader Digital Book setting does not affect the language in which the book is. Reading in a foreign language, you will have to buy them specifically in this language.

• READ TXT FILE IN STEPS

  Hello friends,

  In the past, you have helped me a lot!

  Please, I'm reading the variables in a txt file attached. Variables appear between the lines 5187 to 5236 (49 lines). Below the threshold of 5241 to 5290 (49 lines). After the same variables of the line to line 8342 8293 (49 lines) and line 8347 8396 (49 lines). Among the variables, there is a 3106 line spacing. And so on!

  The Knight of OR helped me a lot to solve part of the problem. His tips were very helpful!

  I would like some advice to unify the txt file variables in just a chart. Is this possible?

  Could change the attached vi.vi?

  Thank you

  The format of your example tab.txt file in do you need?

  If not, I do not consider using a format such as LabVIEW Config File VI or a common standard such as XML.

  If you don't need the exact format in the example, then you will need to write your own parser for him.

• Read last line of a log of the file using UTL_FILE

  Hi all
  
  My environment is--> Oracle 11 g Database Release 1 on Windows 2003 Server SP2.
  Requirement is-> reading last line of a log file with UTL_FILE.
  
  I am reading the last line of a log file that is generated by our own application. I am able to get the last row using the script but the problem below is in the log file, has some blank lines at the end so I get the output as white.

• How to display random lines from txt file

  Good morning (or evening all). I am creating an application and want to display random lines of a text file. I know how to create a text file using file connections, but how can I read the random lines of her?

  OK I got it.

  For beginners like me to have a problem in the future, I was not specify my path correctly. It is not enough to land your .txt in the /res folder and wait for the Simulator to load. You must load from SD card or device memory.

  Use the method found here:

  http://www.weask.us/entry/J2ME-BlackBerry-read-write-text-file

  to use it's as simple as that

  StringfName = "file:///SDCard/Blackberry/text.txt";

  String printLine = readTextFile (fName);

  label.setText (printLine);

  Somewhere in your project directory create a directory called SDCard (I did in my res folder).

  In the Simulator go to switch SD card, then load Select Directory and select the new directory of the SD card. This will create the structure of the SD card in the Simulator. Simply move your .txt in the SDCard/Blackberry directory and run your application.

  Assuming that the file itself readable, you can try using the fourth parameter of FOPEN.

  declare
  f utl_file.file_type;
  s CLOB;
  begin
  f := utl_file.fopen('OUTPUT','outputfile.txt','R',32767);

  utl_file.get_line(f,s);
  dbms_output.put_line(s);
  end loop;
  utl_file.fclose(f);

• Read a .txt file

  I try to know how to read a .txt file and simply set its contents to a variable. Is this possible?

  [Edit] right after the announcement that I found this page which seems like it could be in the sense that I want to go but I have not checked completely yet: http://ExtendScript.blogspot.com/2009/06/read-tab-delimited-text-file.html

  Just post the link for future researchers or if someone will say ' Hey! This isn't what you're looking for! "

  For anyone interested, was the answer to me:

  var fileToParse = file ('path');

  fileToParse.open ('r');

  var dataToGet = fileToParse.readln ();

  fileToParse.close ();

  I need only the line, that's why my example above is so simple.

• Read the lines of the file of the file

  Hello, I followed the example of the http://odiexperts.com/?p=918 here but I get you lines of the file. I want to read these lines and store it in the database.
  
  First, I created a new procedure, with 2 stages and 1 option (called 'count' predefined: 0), then:
  
  ----------------------------------------------------------------------------------------------
  Step 1:
  
  Command in the Source file
  Command on target Jython
  
  filesrc = open('c:\\path\\filename.tag','r')
  first = filesrc.readline)
  lines = 0
  all first:
  lines += 1
  first = filesrc.readline)
  filesrc. Close()
  County = lines
  If the < 1 lines:
  raise "\n cannot further process the file contains lines"
  
  Step 2:
  
  Command on the Source undefined
  Command on target Oracle
  
  INSERT IN TEMP_ROWS_COUNT ('header_count', 'body_count', 'foot_count', 'session') VALUES (#header_num_rows, '< % = odiRef.getOption ("count") % >', #foot_num_rows, '< %=odiRef.getSession ("SESS_NO") % >')
  
  ----------------------------------------------------------------------------------------------
  
  When I run this procedure, it will return no error, but the result of 'count' is always 0. Other values are ok.
  
  What I am doing wrong?
  
  Thank you.

  Hi Angel,

  I wrote the jython script to modify according to your needs. I hope this helps.

  # importing required libraries 
  
  import os
  import string
  import java.sql as sql
  import java.lang as lang
  import re
  
  # program to read the file 
  
  filesrc=open('/home/oracle/test_script.txt','r')
  lines=0
  first=filesrc.readline()
  while first:
       lines +=1
       first=filesrc.readline()
  
  filesrc.close()
  count=lines
  
  # PROGRAM TO INSERT INTO TABLE 
  
  sourceConnection = odiRef.getJDBCConnection("SRC")
  sqlstring = sourceConnection.createStatement()
  sqlstmt= "INSERT INTO ODI_TEMP.TEMP_ROWS_COUNT VALUES ('header','"+ str(count) +"','footer','<%=odiRef.getSession("SESS_NO")%>')"
  
  sqlstring.executeUpdate(sqlstmt)
  
  sourceConnection.close()
  

  Please change the name of the ODI_TEMP to your required schema schema,
  also change the header and footer of your required variables

  co-pilot on source - choose the technology database where there are the TEMP_ROWS_COUNT and the required schema
  and in order to target the above codes.

  I hope this helps. Please let me know if you need any help or code change more to incorporate any logic.

  Thank you

• Cannot read txt file correctly on the cRIO RT after deployment system

  As shown in attachment VI works fine on my system cRIO9073 during execution of the Project Explorer and press the arrow. But unfortunately it no longer works when it is deployed (having a build). This VI is part of a larger project, but I was able to trace the issue to this VI, where something goes wrong with the reading of the text file. I now use the case of fake (not shown), where I have temporary added the txt file content in a string constant. Of course, it's a good solution, but not flexible.

  Anyone have an idea what's not here?

  I use NEITHER-RIO 3.1.0 - January 2009 version as the version of the software on the cRIO system.

  Hello

  I don't know that you still have this issue, but I think that you cannot use this property (axis type) node in your cRIO. If please remove it and try again to see what would be the influence.

  I'll hear it on your part.

  Kind regards
