Write and read a text file

Hi I'm using Flash Cs5 exporting to Air 2
I can write a text file, but am struggling to read in back in. Here is my code so far. Any help would be greatly appreciated
import flash.filesystem.File;
import flash.filesystem.FileMode;
import flash.filesystem.FileStream;
var settingmike="mike57"
var filef:File = File.documentsDirectory.resolvePath("settings6.txt");
var streamf:FileStream = new FileStream();
streamf.open( filef, FileMode.WRITE );
streamf.writeUTFBytes(settingmike);
streamf.close();
filef = null;
streamf = null;
var fileff:File = File.documentsDirectory.resolvePath("settings6.txt");
var streamff:FileStream = new FileStream();
streamff.open( fileff, FileMode.READ);
streamff.readUTFBytes(settingmike);
//I want to see it in a text field called my_textfield
//my_textfield.text=streamff
thanks

this is what works for me when reading an XML file created by the app:
var inXML:XML = new XML();
var ckFile:File = File.applicationStorageDirectory;
var nativeFile:File = ckFile.resolvePath("myFile.xml");
var stream = new FileStream();
stream.open(nativeFile, FileMode.READ);
inXML = XML(stream.readUTFBytes(stream.bytesAvailable));
stream.close();
hope that helps.

    Extra Question::::::: Is it possible to write records to a text file. If you have not idea what I am talking about then ignore it.
    Manny thanks,
    your help is much appreciated though you don't know it!

    Do 3 things.
    -- Look through the API at the java.io package.
    -- Search previous posts for "read write from text file"
    -- Search java.sun.com for information on the java.io package.
    That should clear just about everything up. If you have more specific problems, feel free to come back and post them.

    What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
    I already created a class called Class packet:
    public class packet {
        private int timestamp;
        private int user_id;
        private int packet_id;
        private int packet_seqno;
        private int packet_size;
        /** Creates a new instance of packet */
        public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
            this.timestamp = timestamp;
            this.user_id=user_id;
            this.packet_id=packet_id;
            this.packet_seqno=packet_seqno;
            this.packet_size=packet_size;
    }then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
    any idea and sample code will be appreciated.

    Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
    Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

    Hi
     I am the new user of LabVIEW version 7.1 for testing automation application. I have to measure 33 signals ( mostly analog like temp, pressure, etc...) from NI USB 6210 DAQ system and write in master file for future verfication.From real data or from master file back up have to write  one more file if only the signal reaches steady state , which will used for analysis and same signals to be read from this file parallely & make a waveform and/or table display format.
    Pl. help me to shortout this problem 
    note: I have plan to ugrade labVIEW version 2011 shortly, so let me know doing parrel acquistion write and read file for data analysis in same VI in version 7.1...... 

    Parallel operations in LabVIEW are very simple.  Just code it in parallel and it will work.
    Try taking a look at some of the examples in the NI Example Finder (Help > Find Examples).  There you will find example for writing to and reading from files, as well as data acquistion in parallel with other operations.
    You might need a producer/consumer architecture is you are acquiring data very quickly.

  • Read from text file and seperate column

    hello,
    I have a problem reading my text file. This text file is downloaded from weather link. All data will be changed upon the selection of user. my problem is I can read the data column by column but i cannot retrive the right column header for each data. I also attached the test file.

    Hi
    Sorry, I missed that one. The file formatting is strange though. It uses spaces to separate columns but also within columns. I attached a modified VI that tries to take care of that, but it fails at the columns "Solar Energy" and "Hi Solar Rad.". This is very difficult to read programmatically as there's one space each between "Solar", "Hi", and "Solar" again. So how do we distinguish between column separator and space within column?
    Is download.txt the original file? Or was it probably modified by an editor that would replace tabs by space characters?

    See in this case as you are dealing with Files and database. you need read the File by using the I/O Streams. if you have to select some particular values you can go Random access file.Once you have retrived values. You can go for the second part that is make a jdbc connection to database, and use simple SQL statements to populate those values into the table.
    How this will give you a better picture

  • Issue : Read a text file and print the same

    Hi, My requirement is to read a text file and print it the same way.
    import java.io.BufferedReader;
    import java.io.FileReader;
    public class CatFile {
    public static void main(String[] args) throws Exception
         FileReader file = new FileReader("D:/Test/Allfiles.txt");
         BufferedReader reader = new BufferedReader(file);
         String text = "";
         String line = reader.readLine();
         while (line != null)
              text += line;
              line = reader.readLine();
         System.out.println(text);
    The text file i used contains
    A
    B
    C
    but my output is ABC.
    What change should be made to print it the same way in the txt file ?

    Hi EJP,
    I modified the code based on your suggestion and now its working as expected. Thanks
    Modified code :
    import java.io.BufferedReader;
    import java.io.FileReader;
    public class CatFile {
    public static void main(String[] args) throws Exception
         FileReader file = new FileReader("D:/Test/Allfiles.txt");
         BufferedReader reader = new BufferedReader(file);
         String text = "";
         String line = reader.readLine();
         while (line != null)
              System.out.println(line);
              line = reader.readLine();
              text += line;
    }

  • Read multiple text files and sort them

    I am trying to read multiple text files and store the data from the file in vector.
    but for days. I am with no luck. anyone can help me out with it? any idea of how to sort them will be appreciated.
    Below is part of the code I implemented.
    public class packet {
        private int timestamp;
        private int user_id;
        private int packet_id;
        private int packet_seqno;
        private int packet_size;
        public packet(int timestamp0,int user_id0, int packet_id0,int packet_seqno0, int packet_size0)
            timestamp = timestamp0;
            user_id=user_id0;
            packet_id=packet_id0;
            packet_seqno=packet_seqno0;
            packet_size=packet_size0;
        public void setTime(int atimestamp)
            this.timestamp=atimestamp;
        public void setUserid(int auserid)
            this.user_id=auserid;
        public void setPacketid(int apacketid)
            this.packet_id=apacketid;
        public void setPacketseqno(int apacketseqno)
            this.packet_seqno=apacketseqno;
        public void setPacketsize(int apacketsize)
            this.packet_size=apacketsize;
        public String toString()
            return timestamp+"\t"+user_id+"\t"+packet_id+"\t"+packet_seqno+"\t"+packet_size+"\t";
    }Here is the data from part of the text files. ( the first column is timestamp, second is userid, third is packetid.....)
    0 1 1 1 512
    1 2 1 2 512
    2 3 1 3 512

  • DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file

    Hi
    DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file
    Two main
    sections:
    1)     
    Perform
    write and read operations to and fro different spread sheet files, such that
    each file have a single row of 32bits different binary data (analogous to 1D
    array) where the left most bit is the MSB. I don’t want to manually enter the
    32 bits binary data, I want the data written or read just by opening a file
    name saves with the intended data.
          2)     
    And
    by using test patterns implemented using the digital pattern generator or  build digital data functions or otherwise, I need to
    ensure that the     
                binary data written to a spreadsheet file or any supported file type
    then through the NI-USB 6509 is same as the data read.
    I’m aware I can’t use the simulated
    device to read data written to any port but if the write part of the vi works I
    ‘m sure the read part will work on the physical device which I’ll buy later.
    My Plan
    of action
    I’ve
    created a basic write/read file task and a write/read DAQ task for NI USB 6509
    and both combine in a while loop to form a progress VI which I’m confuse of how
    to proceed with the implementation.
    My
    greatest problem is to link both together with the correct functions or operators
    such that there are no syntax/execution errors and thus achieve my intended
    result.
    This
    project is one of my many assignments for my master thesis, so please i’ll
    appreciate every help as I’m not really efficient with LabVIEW programming but
    I prefer it because is fun and interesting if I get to know it.
    Currently I’m
    practicing with LabVIEW 8.6/NI DAQmx 8.8 Demo versions and NI USB 6509
    simulated device.
    Please see
    the attached file for my novice progress, thanks in
    advance for the support
    Rgds

    What does your file look like?  The DAQmx write is expecting a single U32 value, not an array of I64.
