Load a file into ByteArray

Hi all

First of all, I would like to thank everyone on this forum. You may not know it, but you helped me get up now with my request.

Forgive my stupidity, as I'm a noob with ActionScript. But what I try to do is to read an excel file that I have stored in my src file. Its called "t1.xls".

I use a library called as3xls and this is what my code looks like:

var xls:ExcelFile = new ExcelFile();
var ba:ByteArray = new ByteArray();

var f:File = File.applicationDirectory;
f = f.resolvePath("t1.xls");

ba = tempFiles.data;
xls.loadFromByteArray(ba);

ExcelFile class is a class that comes with the as3xls library.

I get an error when you do this, which is basically telling me that my ByteArray is null. I don't know much, but I suspect that I do not read the file correctly. As I said earlier, the file, "t1.xls" is located in my src folder.

I would like to know if I'm reading the file correctly, and if I do something wrong, how do I make a ByteArray from a file in my src file.

Thanks in advance

Hello

You must first load the file until you can access the ByteArray of this file data.

Here's a simple example:

private function onClick(e:Event):void {
    loadStatus = "Loading file";

    _xlsFile = File.applicationDirectory.resolvePath('sample.xls');
    _xlsFile.addEventListener(Event.COMPLETE, onFileLoaded);
    _xlsFile.load();
}

protected function onFileLoaded(event:Event):void
{
    var ef:ExcelFile = new ExcelFile();
    ef.loadFromByteArray(_xlsFile.data);
    loadStatus = "Loaded sheets: " + ef.sheets.length;
}

You should also know that as3xls is using the Flex framework classes then you will not be able to use this library in your project in pure AS3/QNX.

Here is the example of Flex Hero project where you can see the complete example.

You will need Flash Builder Burrito to open the project.

  • Loading a file into a global variable problem - really a global var text?

    How to access these values after the loading of the external file, after charging?

    Thanks in advance.

    The statement you quoted all Adobe documentation is correct.

    If you want to load the data into the tables before anything else happens, then have everything that happens to run via the function completeHandler... when the data is loaded and processed in the tables.

    the command: loadFile() runs before the trace ("2:" + images [4]); command.  The loadFile function is processed and loading process BEGINS... but begins loading does not delay the main treatment to continue down the line - the loading itself becomes a secondary/background task.  The order was to run the function loadFile and the processing of this function has been completed.  If you don't believe, then add a trace...

    function loadFile (): void

    {

    vars.dataFormat = pouvez;

    vars.addEventListener (Event.COMPLETE, onComplete, false, 0, true);

    Vars.Load (new URLRequest("images/fnames.txt"));

    trace ("implementation");

    }

    If you add this trace, you will see the execution of function loadFile is completed and the following line in your code is then treatment... trace (2...)

    The addEventlistener method does not stop anything.  The addEventListener method code is assigned a monitor, not a traffic controller... it's say the monitor to indicate when the loading data are complete.  It does not do anything to stop the execution of the program.

    So if you want to wait until the data is loaded before anything else... it goes...

    function onComplete(evt:Event):void

    {

    var urlVars:URLVariables = evt.target.data;

    images = vars.data.images.split(",");

    tnails = vars.data.thumbnails.split(",");

    1 make sure of course active loads (for example, lesson1.swf) are added to your panel of ' all files '.

    2. If the loaded file contains actionscript code that is not running, use:

    var mv:Loader = new Loader();

    var lc:LoaderContext = new LoaderContext(false,ApplicationDomain.currentDomain,null);

  • How to load multiple files into multiple tables using a Controlfile?

    Hello world

    I have four different tables with similar structures, get the data from four different data files. I would like to use one control file to load the data from four different files from four different tables.

    Here's the DOF of the tables:

    CREATE TABLE Product_Sales(  
    Year_of_Sale NUMBER,  
    Product_Type VARCHAR2(25 CHAR),  
    Product_Group VARCHAR2(25 CHAR),  
    Category_Type VARCHAR2(25 CHAR),  
    Category_Group VARCHAR2(10 CHAR),  
    Product_Count NUMBER,  
    Product_Amount NUMBER(19,2),  
    Category_Count NUMBER,  
    Category_Amount NUMBER(19,2)  
)  



    CREATE TABLE Retail_Sales(  
    Year_of_Sale NUMBER,  
    Product_Type VARCHAR2(25 CHAR),  
    Product_Group VARCHAR2(25 CHAR),  
    Category_Type VARCHAR2(25 CHAR),  
    Category_Group VARCHAR2(10 CHAR),  
    Product_Count NUMBER,  
    Product_Amount NUMBER(19,2),  
    Category_Count NUMBER,  
    Category_Amount NUMBER(19,2)  
) 

    You still have products_sales instead of product_sales in when your article, so it does not load anything in the product_sales table.  You have not reset the position for the first after subsequent field in the table and when clauses, then it starts looking for the first field to the position you left it in the previous section, instead of 1, so he can't find anything and does load all the data in the household_sales table.  You need to reset the position 1 for each combination of table and what clause after the first.  The first argument is optional.  Please see the corrected below control file.

  • A way to load external files in applications WebWorks

    Hi all

    I am facing the following problem.

    My application is able to play the animation sequences of 16 colors on a screen of matrix of LED 34 x 18.

    I am working on a set of tools that make it relatively easy for people to create their own animations play in my application. I'd love to see what other people come up with.

    But here's the problem: how they load these new animations in my application? On Palm WebOS, it is possible to load a file from any Web host on this platform, I can simply tell the user to put a file on their Web host and enter the URL in my application.

    However, on the PlayBook every domain must be added explicitly permission in the file config.xml for the APP. Therefore, it is impossible for users to load their own Web host files in my application.

    Before I spend more time perfecting these tools for end users (I already use the myself but right now they are a little gross) so I need to know if it will be possible for users to put the files they have created with my tools on their playbook and whether it will be possible to load a file into my application at a given time for example by offering a "Browse" button which exposes the local file system to select a file.

    Is it possible (going to be)? If so, I also opened a repository for people to present animations created then possibly include in next updates of the application.

    Let me know!

    p.s. the app can be seen here.

    In the entertainment section you can see the various animations that I created with my tool. They are stored in a JSON file.

    You can whitelist ' *' to allow access from all domains.

    I think that this limits the possibility for all areas of access to the api specific blackberry however.

    I'm sure it's documented somewhere in the WebWorks getting started guides?

  • Muse is unable to load the files, only on the main computer

    Hi all

    I wonder if anyone has experienced this before, or has ideas on how to solve this problem.

    Worked on a site yesterday.  Hibernated as usual.

    Have went to use the program today to find that it hangs on the bird's eye view on any Web site file I load.

    No errors, it remains just completely inadmissible and needs to be forced to leave.

    The strange thing is my carry around portable can load the file perfectly (the same exact, located in a network Bank).

    I tried to record a new version of the computer that works.  My main computer crashes again.

    I tried to load the file into the pre-release, always falls down.

    I tried uninstalling the computer.

    Restart the computer.

    Installation.

    Still crashes.

    Tried to move the files locally.

    Still crashes.

    I checked the Windows Update, it did not do anything in this period.

    Am quite perplexed.

    Any suggestions would be greatly appreciated.

    I thought I'd try the system restore in Windows to see if it would help.  Went to restore a file from 2 days ago.

    System restore corrupted my Windows even more and because my main drive was Bitlocker protected, he has me very very grumpy and Windows was over.

    30 minutes of trying to fix, my computer now has a new installation of Windows.

    The good news is that muse is working again.

    TL:Dr: If you have a problem with Muse, wipe your entire computer, it suits him.

  • 4.2.3/.4 data support assistant - slow when loading large files

    Hello

    I use the load data wizard to load csv files into an existing table. It works very well with small files up to a few thousand rows. When loading 20 k lines or more loading process becomes very slow. The table has a unique numeric column to the primary key.

    The primary key is declared to the "shared components"-> logic-> "data loading tables" and is recognized as 'pk (number)' with 'case sensitve' set to 'No '.

    When loading the data, these Setup executes the following query for each line:

    Select 1 "Klaus". "' PD_IF_CSV_ROW ' where upper ("PK") = upper(:uk_1)

    which can be found in v$ sql view during loading.

    It makes the process of slow loading because of the superior function, no index can be used.

    It seems that the setting of "case sensitive" is not rated.

    Removing the numeric index for the key primary and with the help of a function based index do not help.

    Explain plan shows an implicit conversion "to_char":

    UPPER (TO_CHAR (PK) = UPPER(:UK_1)

    It is missing in the request, but perhaps that it is necessary for the function based index to work.

    Please provide a solution or workaround to load data Wizard work with large files in a reasonable time.

    Best regards

    Klaus

    You must have the correspondence of PK to be "exactly - case-sensitive" (or something like that)

    In addition, I was already on the slowness with Oracle Support when dealing with important content.

    They are aware of the problem.  Only around is known to break up the data into smaller segments.

    (I'll have to track down the correct ID for reference...)

    My observation:

    APEX data loader makes a slow-by-slow transformation of the data instead of treatment in bulk.

    You will need to break up the data, or to build your own data loader.

    Thank you

  • How to load several files DBF table 1 target using only 1 interface?

    Hello, I am a beginner in ODI and I have a problem.

    I have several DBF / Foxpro files that is stored in a directory like this:
    2010_10/account.dbf
    2010_11/account.dbf

    All DBF files have the same structure, but stored in a different folder (the folder name is < year > _ < month >)

    I managed to create an interface to load a DBF unique for the target table and the source table is hardcoded in the interface. Ideally, the interface will take place once a month.

    How can I use the same interface to load other DBF files?

    I know, if the data source is a text file, you can link the resource name to a variable, and the variable can be set to a file name. But I can't do since I use a JDBC driver to connect to the DBF file.

    Any help will be appreciated

    Hello

    I have no idea on the DBF files, yet...

    What is create a variable to build the 'months' and then pass this variable to OdiFileCopy, move this file to a specific directory. Then run your interface to load this file into your database. Once the work is successful, you can delete the file using OdiFileDelete (optional)

    Thank you

  • APEX 5: FILE item type to BROWSE not load file into the table apex_application_temp_files

    Also added a button load that submits the page. But when I check the apex_application_temp_files of APEX sql workhop table, nothing appears.

    Hi Pierre,.

    has added a dynamic action, submitting travel item.

    How can you submit just the element go? How your dynamic action look like?

    But when I check the apex_application_temp_files of APEX sql workhop table, nothing appears.

    It is by design, because the sight of apex_application_temp_files limited to your current session. In your case at the session of constructor and not your application.

    Add a process to the page that contains the item "Browse file" when you use

    select *
  from apex_application_temp_files
 where name = :page item name;

    to access your downloaded BLOB.

    I load this XML data file into a single table using an external Table. Could someone help me please with coding.

    Thank you

    Reva

    Could you please help me how to insert my XML content into that.

    Same as before, try a plain old INSERT:

    insert into xml_pecos

    values)

    XmlType (bfilename ('XML_DIR', "test.xml"), nls_charset_id ('AL32UTF8'))

    );

    But you'll probably hit the same limitation as with the binary XMLType table.

    In this case, you can use FTP to load the file as a resource in the XML DB repository.

    If the XML schema has been registered with the hierarchy enabled then the file will be automatically inserted into the table.

    Could you post the exact statement that you used to save the scheme?

    In the meantime, you can also read this article, I did a few years ago, it covers the XML DB features that may be useful here, including details on how to load the file via FTP:
