Reand and write object data to / from file

Hi
I have my application data stored in a hierarchical set of objects. I want to store that information to a file and later retrieve it to objects again. The object data consists of Strings, Doubles, etc., but it may contain other data as images. How can I implement this?
Can someone point me out in the right direction? I have seen a serializable approach, but I don't know if it's the right option for me.
Thanx!

I'd still say that's your best bet (unless you feel you need a table and JDBC). As for image data, unless you're going to manipulate them and change their contents, just put them in a folder and use a MediaTracker

  • What is the best combination of read and write objects to binary files ...

    Hi everyone,
    what are the best combination of read and write objects to read/write a record of customers from a binary file. I should be able to use StringTokenizer. I am bit confused with all these Stream reader and writers.
    abdul

    You are, indeed, confused:
    o StreamTokenizer works on character input, not binary input.
    o Readers and Writers in general work on character streams, not binary.
    That leaves you various input streams and output streams for reading binary data.

  • Question around UTL_FILE and writing unicode data to a file.

    Database version : 11.2.0.3.0
    NLS_CHARACTERSET : AL32UTF8
    OS : Red Hat Enterprise Linux Server release 6.3 (Santiago)
    I did not work with multiple language characters and manipulating them. So, the basic idea is to write UTF8 data as Unicode file using UTL_FILE. This is fairly an empty database and does not have any rows in at least the tables I am working on. First I inserted a row with English characters in the columns.
    I used utl_file.fopen_nchar to open and used utl_file.put_line_nchar to write it to the file on the Linux box. I open the file and I still see English characters (say "02CANMLKR001".
    Now, I updated the row with some columns having Chinese characters and ran the same script. It wrote the file. Now when I "vi" the file, I see "02CANè¹æ001" (some Unicode symbols in place of the Chinese characters and the regular English.
    When I FTP the file to windows and open it using notepad/notepad++ it still shows the Chinese characters. Using textpad, it shows ? in place of Chinese characters and the file properties say that the file is of type UNIX/UTF-8.
    My question : "Is my code working and writing the file in unicode? If not what are the required changes?" -- I know the question is little vague, but any questions/suggestions towards answering my question would really help.
    sample code:
    {pre}
    DECLARE
       l_file_handle   UTL_FILE.file_type;
       l_file_name     VARCHAR2 (50) := 'test.dat';
       l_rec           VARCHAR2 (250);
    BEGIN
       l_file_handle := UTL_FILE.fopen_nchar ('OUTPUT_DIR', l_file_name, 'W');
       SELECT col1 || col2 || col3 INTO l_rec FROM table_name;
       UTL_FILE.put_line_nchar (l_file_handle, l_rec);
       UTL_FILE.fclose (l_file_handle);
    END;
    {/pre}

    Regardless of what you think of my reply I'm trying to help you.
    I think you need to reread my reply because I can't find ANY relation at all between what I said and what you responded with.
    I wish things are the way you mentioned and followed text books.
    Nothing in my reply is related to 'text books' or some 'academic' approach to development. Strictly based on real-world experience of 25+ years.
    Unfortunately lot of real world projects kick off without complete information.
    No disagreement here - but totally irrevelant to anything I said.
    Till we get the complete information, it's better to work on the idea rather than wasting project hours. I don't think it can work that way. All we do is to lay a ground preparation, toy around multiple options for the actual coding even when we do not have the exact requirements.
    No disagreement here - but totally irrevelant to anything I said.
    And I think it's a good practice rather than waiting for complete information and pushing others.
    You can't just wait. But you also can't just go ahead on your own. You have to IMMEDIATELY 'push others' as soon as you discover any issues affecting your team's (or your) ability to meet the requirements. As I said above:
    Your problems are likely:
    1. lack of adequate requirements as to what the vendor really requires in terms of format and content
    2. lack of appropriate sample data - either you don't have the skill set to create it yourself or you haven't gotten any from someone else.
    3. lack of knowledge of the character sets involved to be able to create/conduct the proper tests
    If you discover something missing with the requirements (what character sets need to be used, what file format to use, whether BOMs are required in the file, etc) you simply MUST bring that to your manager's attention as soon as you suspect it might be an issue.
    It is your manager's job, not yours, to make sure you have the tools needed to do the job. One of those tools is the proper requirements. If there is ANYTHING wrong, or if you even THINK something is wrong with those requirements it is YOUR responsibility to notify your manager ASAP.
    Send them an email, leave a yellow-sticky on their desk but notify them. Nothing in what I just said says, or implies, that you should then just sit back and WAIT until that issue is resolved.
    If you know you will need sample data you MUST make sure the project plan includes SOME means to obtain sample data witihin the timeline needed by your project. As I repeated above if you don't have the skill set to create it yourself someone else will need to do it.
    I did not work with multiple language characters and manipulating them.
    Does your manager know that? If the project requires 'work with multiple language characters and manipulating them' someone on the project needs to have experience doing that. If your manager knows you don't have that experience but wants you to proceed anyway and/or won't provide any other resource that does have that experience that is ok. But that is the manager's responsibility and that needs to be documented. At a minimum you need to advise your manager (I prefer to do it with an email) along the following lines:
    Hey - manager person - As you know I have little or no experience to 'work with multiple language characters and manipulating them' and those skills are needed to properly implement and test that the requirements are met. Please let me know if such a resource can be made available.
    And I'm serious about that. Sometimes you have to make you manager do their job. That means you ALWAYS need to keep them advised of ANY issue that might affect the project. Once your manager is made aware of an issue it is then THEIR responsibility to deal with it. They may choose to ignore it, pretend they never heard about it or actually deal with it. But you will always be able to show that you notified them about it.
    Now, I updated the row with some columns having Chinese characters and ran the same script.
    Great - as long as you actually know Chinese that is; and how to work with Chinese characters in the context of a database character set, querying, creating files, etc.
    If you don't know Chinese or haven't actually worked with Chinese characters in that context then the project still needs a resource that does know it.
    You can't just try to bluff your way through something like character sets and code conversions. You either know what a BOM (byte order mark) is or you don't. You have either learned when BOMs are needed or you haven't.
    That said, we are in process of getting the information and sample data that we require.
    Good!
    Now make sure you have notified your manager of any 'holes' in the requirements and keep them up to date with any other issues that arise.
    NONE of the above suggests, or implies, that you should just sit back and wait until that is done. But any advice offered on the forums about specifics of your issue (such as whether you need to even worry about BOMs) is premature until the vendor or the requirements actually document the precise character set and file format needed.

  • Write the data into a file in 10 ms interval within 10 sec

    Hi,
    I'm trying to write the data into a file when I press a OK button and the data should write in a file every 10ms interval. After pressing the OK button the process will stop after 10 sec.
    I've attached my VI.
    Problem is that I'm getting the result every ms. How can I get the data every 10ms? So it'll come 1000 data within 10 sec.
    For other calculations purpose I'm using Amplitude and Level Measurements block to get the mean DC voltage, so when I change the Samples to Read and Rates, the process is getting stuck.
    Any kind of suggestion is appreciable.
    Thanks,
    Chotan

  • How do I read from a text file that is longer than 65536 lines and write the data to an Excel spreadshee​t and have the data write to a new column once the 65536 cells are filled in a column?

    I have data that is in basic generic text file format that needs to be converted into Excel spreadsheet format.  The data is much longer than 65536 lines, and in my code I haven't been able to figure out how to carry over the data into the next column.  Currently the conversion is done manually and generates an Excel file that has a total of 30-40 full columns of data.  Any suggestions would be greatly appreciated.
    Thanks,
    Darrick 
    Solved!
    Go to Solution.

    No need to use nested For loops. No need for any loop anyway. You just have to use a reshape array function. The picture below shows how to proceed.
    However, there may be an issue if your element number is not a multiple of the number of columns : zero value elements will be added at the end of the last column in the generated 2D array. Now the issue depends on the way you intend store the data in the Excel spreadsheet : you could convert the data as strings, replace the last zero values with empty strings, and write the whole 2D array to a file (with the .xls extension ) using the write to spreadsheet function. Only one (minimal) problem : define the number of decimal digits to be used;
    or you could write the numeric array directly to a true Excel spreadsheet, using either the NI report generation tools or ActiveX commands, then replace the last elements with empty strings.
    We need more input from you to decide how to solve these last questions.

  • Read and write compressed data from blob in ADF

    Hi All,
    I have a requirement where i need to compress/zip the file, if the file is greater than 2MB and store in database.
    And i need to extract it from database in download dialog as zip file.
    Please suggest me, i m using JDev 10.1.3.5 and using inputFile component or please redirect me to any examples or demos.
    Regards,
    R N V Prasad

    Hi
    I am first uploading file and if the file is more than 2MB, i am compressing it. i used the below method for compressing.
    public void zipFile(String inputFilePath,String outputFilePath,String outFileName){
    long fileSize;
    long twoMBFileSize=2097152;
    String outFileLocation;
    try
    byte[] data = new byte[1000];
    File file=new File(inputFilePath);
    FileInputStream fis=new FileInputStream(file);
    BufferedInputStream in = new BufferedInputStream(fis);
    fileSize = file.length();
    System.out.println("File size.."+fileSize);
    int count;
    outFileLocation=outputFilePath+outFileName;
    System.out.println("outFileLocation..."+outFileLocation);
    ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(new FileOutputStream(outFileLocation)));
    out.putNextEntry(new ZipEntry(outFileName));
    while((count = in.read(data,0,1000)) != -1)
    out.write(data, 0, count);
    in.close();
    out.flush();
    out.close();
    catch(Exception e)

  • Setting up position of front panel objects using input from file

    I am working on a project and i have got the following query.
    i have a front panel with lot of objects like knobs,dials,push buttons etc..
    the entire panel will be the console to the user and as he changes the various
    positions of the objects their values will be written in to a file.
    now after a days work when the system is restarted again the next day
    the values of various objects should be read from the file and the front panel objects should be set in their position according to it
    in short the objects(knobs,buttons etc) should both act as o/p i.e when user interacts with them and they should also act as i/p when their position will be set from
    file.
    how can i achieve this.any help regard
    ing this would be greatly appreciated

    You should separate the read portion of this vi from the write portion of the vi. You want to execute the read portion of the vi only at startup and the write portion of the vi only at shutdown. So you'll be reading the file and writing the output to the property nodes, running your program, and then taking the value of the controls and writing to file. I have attached an example of how this might work. You might also do this with a state machine structure to control the data flow.
    Hope that helps

  • What is the fastest way to record and write image data?

    Hello,
    I am new to labview and am using the IMAQ software package to record and write data from a CCD camera to the hard drive. The end goal is a program that records and saves as much data as possible as quickly as possible, for experiments lasting on the scale of days. I have been experimenting with the snap, grab, and sequence methods of recording. To save the image data I was told by NI customer support that TDMS streaming would be the fastest method. I have also been experimenting with the TDMS VIs, however I have found the IMAQ Write File 2 VI to be faster in practice. Am I doing something wrong with the TDMS file structure? Is there a more efficient way to convert IMAQ image data to a dataform that can be written as TDMS? I am posting two of my programs to provide a clearer example of what I am trying to do. The first takes a snap of the image and appends it to a TDMS file. The second is the fastest I have found so far and uses Grab to record the images and the IMAQ Write File VI to save them. 
    Thanks

    Hi
    For me it is no surprise that the second VI is faster then the first one, the reason is you can not compare this two VI with each other.
    In the first VI you work with TDMS files, in the second with png files. That would be much faster, because TDMS files need a lot of diskspace.
    Second point, why do you open, write and close for eacht iteration of the for loop a TDMS file in your first VI? That need really a lot of resources, so it coudn´t be fats as well.
    Save your converted pictures in one array, an after the acquisition you can save it in one TDMS file. When you need for each picture a TDMS file you have to know that this need some time to do this.
    So now for the architecture of your first VI, please look to the LL Sequence.vifrom the examples (C:\Program Files\National Instruments\LabVIEW 8.6\examples\IMAQ\IMAQ Low Level.llb\LL Sequence.vi), there you can see how an acquisition of a number of images have been to do.
    When you like it really fast, you make a producer/consumer architecture (see examples in LabVIEW for that).
    So in the first whileloop you acquire the images, write into a queue and in the second, parallel whileloop you read the queue and save the images. (see attachment)
    Hope that helps
    Kind regards

  • Read a bfile and write its contents in a file stored in my hard disk

    I will try to describe my problem as clearly as I can.
    I have created a table that includes a LOB column "BFILE"
    Then I'm trying to READ the BFILE stored in our database using the
    DBMS_LOB package.
    so far so good.
    Now I want to write these data that I have read in the step above in a file
    saved in my local disk. The problem is, since the file in databse is
    stored as binary and I read Raw Data , I cannot create an exact copy of this
    file. It seems that It doesn't write the RAW data in the binary format.
    I have used the DBMS_LOB.READ to read the data and it works fine.
    Now I want to create a file in my local disk and dump the data that I have
    read from the BFILE that has been initially stored in the database.
    Is there any solution to this problem?
    I hope to hear from you soon
    Thanks in advance

    ignore me now.... I answered my own question a short while

  • How to write xml data to a file

    Hi all,
    We have a requirement of writing the xml data into a file in given directory in the server. Generating the xml data using the sql query below.
    SELECT XMLELEMENT ("ROW",
    XMLELEMENT ("CELL", xmlattributes ('EBIZCZMDL_01' AS "colname"), inventory_item_id),
    XMLELEMENT ("CELL", xmlattributes ('EBIZFFMT_01' AS "COLNAME"), attribute29),
    XMLELEMENT ("CELL", xmlattributes ('COMMON' AS "COLNAME"),inventory_item_id || '' || attribute29 || 'ITM')
    AS "RESULT") "XMLDATA"
    FROM apps.mtl_system_items_b
    When we try to write the the data from this query to a file using UTL_FILE.put_line, the script gives the error
    PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
    If somebody can help us pls.......
    Thanks in advance

    Hi Odie,
    We are looking at the xml data to be like the below:
    - <xref xmlns="http://xmlns.oracle.com/xref">
    - <table name="NAPP_ITEM_ITEMID">
    - <columns>
    <column name="EBIZFFMT_01" />

    </row>
    </rows>
    </table>
    </xref>
    We have managed half way trying to get the structure. As we are new to this XML Programming.
    The call to dbms_xslprocessor.clob2file is within the cursor loop for the given SQL.
    DECLARE
    l_file_name VARCHAR2 (30);
    l_file_path VARCHAR2 (200);
    CURSOR xml_cur
    IS
    SELECT XMLELEMENT
    ("ROW",

    xmlattributes ('EBIZCZMDL_01' AS "colname"),
    inventory_item_id

    attribute29
    XMLELEMENT ("CELL",
    xmlattributes ('COMMON' AS "COLNAME"),
    inventory_item_id || '' || attribute29 || 'ITM'
    ) AS "RESULT"
    ) "XMLDATA"
    FROM apps.mtl_system_items_b
    WHERE attribute29 IS NOT NULL;
    BEGIN
    l_file_path := '/usr/tmp';
    l_file_name := 'TEST_XREF4.xml';
    FOR xml_rec IN xml_cur
    LOOP
    dbms_xslprocessor.clob2file(xml_rec.XMLDATA, l_file_path, l_file_name, nls_charset_id('UTF8') );
    END LOOP;
    END;
    Please see the above code snippet and help us if we are doing something wrong.
