Deny access from deleting *.txt file?

HI all,
I have created a *.txt file from xcode with objective c using NSFileManager.Also i gave permission to this file like below,
[NSDictionary dictionaryWithObject:[NSNumber numberWithUnsignedLong:0000u] forkey : NSFilePosixPermissions];
so that there is no read/write permissions.This is working fine too.
Apart from above,i want to deny users from deleting this file..How can i mention this in objective c.?Please help..
Thanks
Athira

Hi Athira,
You'll have more luck in getting a response to this if you posted in on the Apple Developer Forums.

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Problem on reading and writing from from a *.txt file

I get Problem on reading and writing from from a *.txt file. The following is the read() method...
The software said the DataInputStream is depreciated. Can anyone help me please?
public void read()
    File file = new File("C://Documents and Settings//Charles//My Documents//Brunel//EE2065//Assignment and Lab//Assignment 4 and Lab 4//data.txt");
    FileInputStream in = null;
    String str = "";
    try
      in = new BufferedReader(file);
      //in = new FileInputStream(file);
      for(;;)
        str = new BufferedReader(in).readLine();
        //str = new DataInputStream(in).readLine();
        if(str == null)
          break;
        System.out.print(str);
    in.close();
    catch(IOException e)
        System.err.println("execution error: " +e);
}

Thank you for your reply. I have made some change. However, there is an incompetable type found error.
in = new BufferedReader(new InputStreamReader(in));The following are all of the code.

        //str = new BufferedReader(in).readLine();
        //str = new DataInputStream(in).readLine();

How to retrieve IndividualStrings from a txt file using String Tokenizer.

hello can any one help me to retrieve the individual strings from a txt file using string tokenizer or some thing like that.
the data in my txt file looks like this way.
Data1;
abc; cder; efu; frg;
abc1; cder2; efu3; frg4;
Data2
sdfabc; sdfcder; hvhefu; fgfrg;
uhfhabc; gffjcder; yugefu; hhfufrg;
Data3
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
i need to read the data as an individual strings and i need to pass those values to diffarent labels,the dat in Data3 i have to read those values and add to an table datamodel as 6 columns and rows depends on the data.
i try to retrieve data using buffered reader and inputstream reader,but only the way i am retrieving data as an big string of entire line ,i tried with stringtokenizer but some how i was failed to retrive the data in a way i want,any help would be appreciated.
Regards,

Hmmm... looks like the file format isn't even very consistent... why the semicolon after Data1 but not after Data2 or Data3??
Your algorithm is reading character-by-character, and most of the time it's easier to let a StringTokenizer or StreamTokenizer do the work of lexical analysis and let you focus on the parsing.
I am also going to assume your format is very rigid. E.g. section Data1 will ALWAYS come before section Data2, which will come before section Data3, etc... and you might even make the assumption there can never be a Data4, 5, 6, etc... (this is why its nice to have some exact specification, like a grammar, so you know exactly what is and is not allowed.) I will also assume that the section names will always be the same, namely "DataX" where X is a decimal digit.
I tend to like to use StreamTokenizer for this sort of thing, but the additional power and flexibility it gives comes at the price of a steeper learning curve (and it's a little buggy too). So I will ignore this class and focus on StringTokenizer.
I would suggest something like this general framework:
//make a BufferedReader up here...
do
String line = myBufferedReader.readLine();
if (line!=null && line.trim().length()>0)
line = line.trim();
//do some processing on the line
while (line!=null);So what processing to do inside the if statement?
Well, you can recognize the DataX lines easily enough - just do something like a line.startsWith("Data") and check that the last char is a digit... you can even ignore the digit if you know the sections come in a certain order (simplifying assumptions can simplify the code).
Once you figure out which section you're in, you can parse the succeeding lines appropriately. You might instantiate a StringTokenizer, i.e. StringTokenizer strtok = new StringTokenizer(line, ";, "); and then read out the tokens into some Collection, based on the section #. E.g.
strtok = new StringTokenizer(line, ";, ");
if (sectionNo==0)
//read the tokens into the Labels1 collection
else if (sectionNo==1)
//read the tokens into the Labels2 collection
else //sectionNo must be 2
//create a new line in your table model and populate it with the token values...
}I don't think the delimiters are necessary if you are using end-of-line's as delimiters (which is implicit in the fact that you are reading the text out line-by-line). So the original file format you listed looks fine (except you might want to get rid of that rogue semicolon).
Good luck.

Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.

How to calculate the number of vowels from a txt file. Pls give me a hand!!

Guys! How do i calculate the number of vowels from a txt file? I have to create a program to count the number of words, sentence, and vowels. So far I had managed to count the number of words. Now I need help on counting sentence and vowels! Pls give me a hand guys!

I first have to read from the file not the string.I
know how to read from a file. Now the problem ishow
to compare a character from a txt file!You fail to understand, that you have read the data
from the file into a string. Now loop over all
characters in the string. Forget about the file.
KajOr forget the scanners just as others have told you. Just read the file character by character using a FileReader.

Reading integers from a .txt file and computing means

I have a program that uses for loops to produce ten integers (1-10) are returns the average mean, geometric mean, and harmonic mean.
Now i need to change this program to read integers from a .txt file and return the same data. Basically i need to change my for statements that are incrementing to read the text file.
Thanks guys.

You haven't asked a question. You haven't posted code. What are you expecting here?
But I guess I'll take a stab at it and say you should look at the Scanner class
http://java.sun.com/javase/6/docs/api/java/util/Scanner.html
or BufferedReader
http://java.sun.com/javase/6/docs/api/java/io/BufferedReader.html
I'll never understand what makes people come to the forums, create an account, and ask a lazy question, when they could get a great answer much quicker through Google.

All table components seem to need a database. I do not use any database. I run exe files that give output to txt files. How to solve it?
I appreciate any help in this regard...
dr.mohan rao

there may be another way. This is some thing some thing I can recommend. You can create property type of ObjectListDataProvider in session or application based on the scope you required. Create web bean class with property you want to show in the column (say col1, col2, col2). Initialize the list property like similar below
List dataList = new ArrayList();
ObjectListDataProvider mytableprops = new ObjectListDataProvider();
try {
//start loop read data from your txt file
//create instance of web bean for each line
//add web bean instance into dataList
//end of loop readind data from txt file
oldpins.setList(dataList );
oldpins.setObjectType(NotificationProfileBean.class);
} catch (Exception ee1){;}
return oldpins;

What is the 'quickest' way to read char data from a txt file

Hello,
What is the 'quickest' way to read character data from a txt file stored on the phone to be displayed into the screen?
Regards

To be even a bit more constructive...
Since J2me does not have a BufferedInputStream, it will help to implement it yourself. It's much faster since you read large blocks at ones in stread of seperate chars.
something line this lets you read lines very fast:
while ( bytesread < filesize ) {
         length = configfile.read( buff, 0, buff.length );
         // append buffer to temp String
         if ( length < buff.length ) {
            byte[] buf = new byte[length];
            System.arraycopy( buff, 0, buf, 0, length );
            tmp.append( new String( buf ) );
         } else {
            tmp.append( new String( buff ) );
         // look in tmp string for \r\n
         idx1 = tmp.toString().indexOf( "\r\n" );
         while ( idx1 >= 0 ) {
            //if found, split into line and rest of tmp
            line = tmp.toString().substring( 0, idx1 );
         /// ... do with it whatever you want ... ////
            tmp = new StringBuffer( tmp.toString().substring( idx1 + 2 ) );
            idx1 = tmp.toString().indexOf( "\r\n" );
         bytesread += length;
      }

Importing accents from a txt file

Hi everyone
I have the following proble that I can't solve for now:
I've got a pdf file with forms
I've got an excel file that I export to txt (tab delimited text file)
When I import the data from the txt file to the pdf everything is fine but the french accents (é or è or à). For example the "é" becomes a " ,".
I thinks it might be related to unicode or utf but I don't know how to export properly then import those characters.
Any idea ?
Thanks
Florent
PS: I'm using Excell 2011 on MAC and Acrobat 9 Pro.

Done that already, no luck.
I've saved in all the txt formats possible in my Excel.

Importing Text From A .txt File

Hey guys,
I'm looking for a way to import text from a .txt file but I'm totally lost. If someone could point me in the right direction that would be awesome

Hi Prails
This script is basically what you asked:
#target illustrator
#targetengine main
function copyText(){
    var textFile = File.openDialog ("Select the file");
    if (! textFile.exists || app.documents.length==0){
        return;
    textFile.open("r");
    var txtContent = textFile.read();
    textFile.close();
    var doc = app.activeDocument;
    var textItem = doc.textFrames.add();
    textItem.contents = txtContent
copyText ();
Basically what you need to do is declare the text file, open it, read the content and close it. Then, you create a new text item in the Illustrator document and write the content once catched into the text item.
You could continue to work with the variable "textItem" in my example script if you want to set properties like the size, color of the text, position and so on. Also, if you want, replace the first line of the function var textFile = new File ("~/Desktop/Test.txt"); by var textFile = File.openDialog ("Select the file"); so the scripts opens a dialog to ask you the file you want the copy the content.
Hope to be helped
Best Regards

Reading Last line(record) from a txt file ina java

Hi,
I want to retrive the last line from a txt file.Can anybody help me??
Thanx in advance

In order to read the last line you must read all the lines before it. To read lines you can use the BufferedReader and LineNumberReader classes.
Here's an example of how to read lines of text from a file:

Reading a PublicKey \ PrivateKey type from a txt file

Hi,
i want to read a PublicKey \ PrivateKey type from a txt file and input it into a method.
How can i read the data from the file while keeping or converting back to PublicKey \ PrivateKey type?
I'm working with the following:
generate = KeyPairGenerator.getInstance("ECDSA", "FlexiEC");
generate.initialize(ecParams, new SecureRandom());
KeyPair keyPair = generate.generateKeyPair();
............continues
**and then i write the keys to the a simple txt file.**
thanks!
Edited by: sk16 on Apr 8, 2010 10:03 PM

So, if i work with the two above is it ok, like:
generate = KeyPairGenerator.getInstance("ECDSA", "FlexiEC");
               generate.initialize(ecParams, new SecureRandom());
               KeyPair keyPair = generate.generateKeyPair();
               // Pub. and Priv. key objects.
               PublicKey publicKey = keyPair.getPublic();
               PrivateKey privateKey = keyPair.getPrivate();
               // Write keys to separate files.
               FileOutputStream fos = new FileOutputStream(publicKeyFile);
               fos.write(publicKey.getEncoded());
               fos.close();
               FileOutputStream fos1 = new FileOutputStream(privateKeyFile);
               fos1.write(privateKey.getEncoded());
               fos1.close();
and then for example>>>
DataInputStream in = new DataInputStream(
          new FileInputStream("publicKeyFile.txt"));
          byte[] encodedPublicKey = new byte[1024];
          in.read(encodedPublicKey);
          in.close();
          X509EncodedKeySpec encodedPublicKeySpec = new X509EncodedKeySpec(encodedPublicKey);
          KeyFactory keyFactory = KeyFactory.getInstance("ECDSA", "FlexiEC");
          publicKey = keyFactory.generatePublic(encodedPublicKeySpec);
