Print the contents of a collection

I have a collection that is defined as below

type t_collect1 is table of tab1% rowtype directory index;
v_collect1 t_collect1;

I try to print the contents of this collection as below

I'm looping v_collect1
dbms_output.put_line (v_collect1 (i));
end loop;

I also tried one of the columns in the collection, showing as

I'm looping v_collect1
dbms_output.put_line (v_collect1 (i) .col1); -where col1 is a specific column in the table tab1
end loop;

Can help find anyone, how we can print the contents of the collection?

  • You want to print the contents of the textfield.

    I want to print the content of the text field with a button. I know how to print a clip. If I turn the text field in a clip, I can't type anything in it, and then I need to print an empty textfield... Help, tip? Thank you.

    There should be no problem converting your textfield to a movieclip and then by typing in it.  you do not really change it to a movieclip, you just add it to the timeline of the movieclip.

    but your textfield must already be in a displayobjectcontainer and so can be added to your printjob.  for example, if your textfield (for example, tf) is on the timeline in the scope, you can use:

    var pj:PrintJob = new PrintJob();

    b.addEventListener (MouseEvent.CLICK, f);

    function f(e:MouseEvent):void {}

    If (pj.start ()) {}

    try {}

    pj.addPage (this, Rectangle (tf.x tf.y tf.width, tf.height)) of new;

    } catch (error) {}

    handle the error

    }

    PJ. Send();

    }

    }

  • Print the content of a dynamic text

    I can't print the content of a dynamic text

    The clip is: var dates: text_box = new boite_texte();

    Its content is generated by function:

    function onTxtComplete(e:Event):void {}

    .....

    dates.labelOut.text += (Heading1 + "\n\n" + day1 + "\n");

    }

    and appears regularly.

    Now I want to print the contents of dates.labelOut.text

    It works :

    function onPrint(e:MouseEvent):void {}
    var Note: String = "SOME DUMMY TEXT" + "\n\n\n";

    ...

    }

    But not with dates.labelOut.text :

    function onPrint(e:MouseEvent):void {}
    var Note: String = "SOME DUMMY TEXT", "\n\n\n" + dates.labelOut.text;

    ...

    }

    It is a problem of syntax?

    If the trace() works, then printing might work:

    var Note: String;
    button.addEventListener (MouseEvent.CLICK, onPrint);

    function onPrint(e:MouseEvent):void {}
    var today: Date = new Date();
    var Note: String = "EXPRESSION on a daily BASIS" + "" + date + "\n\n\n" + dates.labelOut.text;


    trace (score)

    var printNote:PrintJob = new PrintJob();

    If (printNote.start ()) {}
    try {}
    var pageSprite:Sprite = new Sprite;
               
    var noteText:TextField = new TextField();

    noteText.multiline = true;

    noteText.wordWrap = true;
    noteText.width = printNote.paperWidth;
    noteText.height = printNote.paperHeight;
    noteText.text = notes;
        
    pageSprite.addChild (noteText);
    printNote.addPage (pageSprite);
    } catch(e:Error) {}
    trace ("there was an error");
    }
    printNote.send ();

    pageSprite = null;

    }
       
    }

    For example, Bi Publisher generates a pdf file in the apex that allows to print the content of a blob.

    Let's say you have a record with test.xls in a blob, then I take the test.xls off the record and have bi publisher print it.
    Thank you

    Why would you want a PDF print on an Excel file? Why not just open the Excel file in the browser and print it like that? BI Publisher would not understand the content of the Excel file because it includes xml...

  • Windows Media Player - print the contents of the library

    Hi guys

    I have a pretty extensive library of music stored on my PC and run on Windows Media Player 11.

    My wife just bought a new MP3 player and I want to select these pieces she wants synched on his device.

    I want to do it is have a print to track quotes as they appear in the WMP library so that it can go through and mark the tracks you want she wants. At the moment I can't find a way to do this other than by entering a series of screen shots and pasting in Word.

    Any suggestions there or the will of the screenshot is the only way.

    I want to avoid having us as well sitting there scroll down the list and choose the tracks as they appear.

  • Print the contents of the database or by creating a pdf file of him

    Gidday guys

    Today I am researching using AS3 AIR to format and print data from a database.

    He needs to...

    -take the data and is in the shape of a selection of page formats

    -print it on the printer, or save it in pdf format

    I wonder if someone with experience can you please push me in the direction of research just to answer to...

    -What is the process of taking data and formatting in an object to print into a pdf file?

    -is the purpose you do for printing a sprite? It is for multi page printing, you create several sprites that contain your data in the format in a particular way and then create a multipage out of them.

    Bravo for your advice.

    Without having to rely on the user having a PDF driver installed on your computer, you will need a library like AlivePDF for him do print in pdf format.

    A workflow can be: recover your data via php/Flashvars > fill your prepared model document > use AlivePDF to print to PDF.
