confusion about 'this '.

AS2 code

this.firstChild.childNodes;

What does "this" object and what would be the conversion on AS3.

'This' is the reference to the current instance of the class.

for example:

class A

{

public void callMe()

{

trace ("this is the current instance of a" + this);

}

}

Now suppose I have write a snippet of code as below.

var Temp1 = new A();

var temp2 = new A();

Temp1.callMe ();  'This' method callMe here will refer to the object "temp1".

Temp2.callMe ();  'This' callMe method now appoint "temp2" object.

Inshort 'this' variable refers to the current object that is to be executed.

Back to your point 'this.firstChild.childNodes', this is referring to the class where the code is written.

I guess that you extend the XML class to customize the feature their.

Hope I'm not too complicated... Tell me if this helped...

  • Completely lost and confused about this thing of VM...

    Hello... I'm eager to try this thing any virtual machine so that I can try windows 10. I can't just update windows 10 because I use my laptop for school and there are too many conflicts, glitches, or whatever you want to call them between the programs that I use for school and windows 10. in any case and through my school I have access to the Dreamspark site and downloads (if you are not familiar with what is, I think that its really irrelevant necessarily anyway). Well, I burned the iso image to a disc and I have a folder of virtual disk on my computer so I think that means that I have downloaded the program, but when I open it and try to run it it always says that to restart or insert media that tells it where boot them from. so I try to run the components of integration of the iso image and he tells me the same thing. I am completely lost and totally frustrated and hope that someone can better explain the proper procedure, I should take to do this "thing"!  the operating system running on my laptop at the start is Windows 7 Professional 64-bit. Don't know what other info would be relevant, so if I left out anything important, just ask and I will specify.  Thanks in advanced for any help.

    I'm not familiar with the Microsoft Dreamspark program, but install Windows 10 on a Virtual Machine on a host Windows 7 is pretty simple using VirtualBox, a free application.

  • Confusion about this internet security software is necessary

    I'm getting cofused on how internet security, antivirus software, I should have on my computers.

    I have a desktop computer XPS 420 new with 4 GB memory and 750 GB hard drive and a laptop Inspiron 6000 with 1 GB of memory and 60 GB hard drive.  They are currently networked via a Netgear WNDR3300 wireless router.  My HP C6280 printer is connected to the network.  The new '' runs under Windows VISTA SP1 and the laptop, Windows XP PRO SP2.

    I'm trying to get my software installed on the new office.  For years I used the Norton Antivirus software, and then more recently the Norton Internet Security software.  But when I got the installation of the network, it Norton is in contradiction with the old rounter Netgear WGT624V3-, on the recommendation of the technician fixing the system, so I started using Trend Micro Internet Security.  That worked fine until I upgraded to Trend Micro Internet Security PRO 2008, and it took so much of my computer's resources (especially my old Dell Dimension 8250) runs.  Also, with the old Netgear router, I had to disable the internet as security options was a conflict.  So I experimented on the laptop with a free version of AVAST and Ad-Aware SE Plus.  These two worked together pretty well, and I had all decided to replace the Trend Micro software on the old desktop until I finally decided to buy the new computer.

    Now, I'm in a quandry again.  With the Netgear WNDR3300 router, I have their security WPA - PSK, put in place.  My VISTA Dell supplied with Windows Defender.  Tonight, I tried to install Trend Micro Internet Security PRO 2008 but was told by VISTA that Trend Micro is not compatible with my version of the operating system.   I asked the population of Netgear if I still needed to install software of internet security in addition to the protection in view of their security options AVAST antivirus software and told me I should.  Currently, I have only the AVAST Home edition on the new office.

    What are some of your recommendations? I'd go back to Norton?  Is Windows Defender and AVAST with the Netgear security option enough? Any suggestions will be greatly appreciated.


  • Confused about "additional control Points.

    Hello

    I'm confused about this sentence from database Concepts 11g Release 2 (11.2)

    Additional control points

    An additional control point is a type of thread control point in part intended to avoid writing a large number of blocks online redo log switches. DBWn checks at least every three seconds to determine if he has to do. When DBWn written stamps Sales, it advances the position of the control point, causing CKPT write the position of the control point to the file control, but not for data file headers.

    I thought that a checkpoint is written datafileheader and controlfile, this happens for example after a switch logfile - right?

    So, why not in the case of additional control point? For best performance?

    Additional control points to reduce the time to recover, as more data is committed to the files of data, right?

    There are many types of control points. One that will be updated on the headers of data files would be a complete control and would be applicable to the entire base. The additional control point is induced to keep on enhanching a counter that would ensure that only certain limited stamp Sales would be recovering. That's why a moment of the additional control point, data file headers are not being updated. Control file is probably updated with a "pointer to disk" which mentions the point up to which the dirty buffers are written in files (from the buffer cache) data and where to start the recovery, if necessary. Log file switch will cause a thread control point which, for one instance, would be considered a Global checkpoint only. The additional control point would be for various other reasons such as setting a value for the parameter Fast_Start_Mttr_Target etc.

  • I'm confused about my billing

    I have Adobe Creative cloud and I went to the student. I understand that the $12 plan / monthly is only for the first year, but when he jumped to $65 per month which was a pretty big leap (especially for someone who is still a student) and so I called Adobe customer service. I was told that I had changed my plan in October, something I never remember to do, but the representative I spoke with said she would get back on the plan of the student for $21 / month, and I will get a refund of $27,23. I realized that I was not getting a full refund because I was already at middle of January so I was fine with that too. The same day I receive a supplement of $21,23 and no refund. I remind them again and asked what was going on and said it was a policy of the company to charge the monthly fee for the new plans from the outset. I asked the officer if that's the case, why I do not get a full refund for the $65 I paid this month. She said it was because I was already in the month of January and this is what she was allowed to give me. I asked what month the charge $21.23 is for. She said it was for January. I told him that he didn't add up because according to its share of January has already been used and paid and cannot be refunded but I'm being charged for the total amount of January again under the student rate she changed her of me. I should get a full refund, as new charges $ 21.23 should cover the entire month or if I can not pay the full amount of $65 then I should get an amount proportional instead of a full $21.23 since according to its share of January is already paid and cannot be refunded. Even if I don't get a refund later, all I'm really going back to the day of $5,59 if you take into account the $21.23 I'm running at the front which is practically nothing in Exchange to go through this ordeal. I would have been better off I don't got no refund and just got charged for the month next February. She said she would take the case to his superiors to be studied by a higher office and gave me a case number. I am still confused about this because it just didn't seem like a good way to do business. I feel like I'm being charged twice for the days of service used. None of this makes no sense to me.

    Hello

    I'm confuse about autonomous OBIEE and OBIEE integrated this model two...

    Are these two situation based on the same application (and then after that install US based on the standalone OBIEE, BI applications it become integrated model)

    or are they two separate applications but integrated OBIEE this model can support BI applications?

    Kind regards

    Anne

    Hi Anne,.

    It's the difference,

    Autonomous OBIEE - has no any solution of BI preconstruitse, we build the solution based on our requirement with the suite of products.

    Integrated OBIEE or OBI Apps - are built on standalone. It provides this stand-alone version features all, moreover, it has predefined solutions.

  • BlackBerry smartphones, I am new and confused about things 'connection '.

    I am a new BlackBerry - I have a Curve 8320, I am a small business owner, and I'm not connected to a BES. I use the BB Desktop Manager to synchronize with Outlook and to back up my BB and I did pretty well on most things, but I have still a few things that I leave me puzzled. In this forum, I will ask my "questions of confusion" about data options.

    I have a data plan "pay as you go" with AT & T, my provider, because there is practically no cell reception at home where I work. (I not use my BB for email since I was at my computer most of the time). I have a home network set in place and I have incorporated a router that supports wireless. I have connected a netbook to the wireless network and used to surf the Internet, so I know that my wireless connection works. I also managed to create a wireless connection on my BB to this network and on the home screen, it appears the name of my wireless network when I am here at home, so, I know that the device is connected to my network.

    BUT I don't think that I'm really using my home wireless network... I tried the other day browsing the Internet, and then AT & T told me that I hired data charges - I thought that I should not have if I wasn't using their network. Either I am wrong all assuming that they don't charge me if I use my network or I have something set up properly on my BB... someone can provide some guidance?

    Then, I don't really understand what BIS... I searched through the KB and couldn't find something that sets actually BIS... could someone please explain what BIS?

    Finally, can someone please explain the difference between "mobile network" and "wi - fi"? Apparently, if I disable "mobile network" I have no connection at all, including wi - fi. Is that the way things should be? But, I can turn off wi - fi and always get a connection (if I go out too far from my house, South possible and face).

    Thank you... and now I'm leaving the Forum of BB Desktop Manager to ask some questions here!

    Thanks to all who responded... I now have a much better understanding of the work of the whole thing "data". I disabled my LAN connection, which should avoid all charges. The part that confuses me the most, is that AT & T said would not have to pay to use my own wi - fi, but... it doesn't seem to be the case. So, McDonald's and Starbucks will work very well for me.

  • Confusion about the requirements for the 2015 CC software

    I currently have Windows 8.0 (64 bit) which is so satisfactory and stable.  I have not upgraded to 8.1 Windows because I can't install same normal updates for Windows 8.0 without experiencing freezes system that only restore points can heal.  So for now, I would stick with what I have.  But the problem is the confusing requirements for various programs within the pile of creative cloud applications:

    Premiere Pro: Microsoft Windows 7 Service Pack 1 (64-bit) or Windows 8 (64-bit)
    Photoshop: Microsoft Windows 7 with Service Pack 1 or Windows 8.1

    Illustrator: Microsoft Windows 7 with Service Pack 1, Windows 8 or 8.1 Windows

    Dreamweaver: Microsoft Windows 7, Windows 8 or 8.1 Windows

    Hearing: Microsoft® Windows® 7 with Service Pack 1 (64-bit), Windows 8 (64-bit) or Windows 8.1 (64-bit)

    So what I'm confused about is the fact that Windows 8.0 is not listed for Photoshop, but Windows 7 and Windows 8.1 are.  Does this mean Photoshop CC 2015 is not compatible with Windows 8?  And that means that Premiere Pro is not compatible with Windows 8.1 since only 7.0 (SP1) and 8.0 are listed, I would have preferred the upgrade of software CC WITHOUT update Windows since I am picky on my installation of Windows 8 stable pipes now solid as a rock.  Fortunately, Illustrator, Dreamweaver, and hearing are compatible with all three, it seems.

    Can someone clear up the confusion, please?

  • Confused about trandata

    Hi all

    I'm confused about additional logging.

    I have golden gate replication, but in primary db.

    Is this related to archive the recording? It works even if I'm not on the archive log?

    Installing Oracle: orcl

    Enable supplemental logging (required on primary database only)

    SQL > alter database adds additional log data;



    Hello

    One of the main reasons to enable additional logging is to generate logs for the update statement. As insert and remove implies the change to an entire line (addition or deletion of a complete line) and all the columns it while updating can occur on a column of a row.

    Additional logging on the side of database source to some of the columns are very well required to ensure that these changes to the columns that are supplemental logging enabled will be applied with success in the target database. With the help of these additional columns, oracle decides the lines that need to be updated on the destination side. This is so the extra logging is more imperative for replication.

    Just bought a Nikon d750 and confused about adobe LR4 and PS6 support for RAW files. I have 8.7 DNG, but I was wondering if LR and PS will import direct soon thanks for all the tips

    Support for the Nikon D750 was introduced in the last version of LR 5.7 and ACR 8.7 Novemder 18 2014.

    New updates for LR 4 were arrested when LR 5 was released on June 9, 2013. No other updates of bug fixes and new camera support.

    Nada, LR 4 will never support Nikon D750. The Nikon D750 was introduced on the market in September 2014 some 15 months after further development of LR 4 was arrested.

    You can use the Adobe DNG (free download for packing) program to convert your Nikon D750 Nef (raw) files in Adobe's DNG format which will allow you to import those into LR 4. This is the crutch provided by Adobe to allow the processing of raw files with versions out-of-date LR and ACR.

    You can also update the ACR for PS CS6 version 8.7 plugin that can also work with the raw files of the D750. For direct support in Lightroom, you will need to upgrade (paying) to version 5.7.

  • Confused about the new creative cloud

    Hi all

    Since I read adout the new creative cloud I'm confused about what will happen to my license for Adobe Lightroom. Will they remain still desktop apps as well or I have to pay for an annual license, if I want to use new versions of Lightroom?

    I am a casual photographer and I like to use Lighroom for my photos, but I don't think that pay for an annual license because I'm not spending a lot of time, image-editing.

    Can someone clarify this for me?

    Thank you very much

    Lucian

    5 Lightroom does not have subscription only, you're fine. There is no sign that it will even happen in the foreseeable future either.  It's just the ex-Creative-Suite that all talk.

    Target market of Lightroom is different from the Creative Suite/Cloud. CC is a good deal for the majority of its base of users (next door), while the majority signed without major complaints.  Lightroom has a huge customer base amateur, and they would be much more difficult to convince us to go subscription only. They would be likely to lose most of customers of Lightroom at the moment, and they are not completely stupid.

    Hello world
    I have some confusion about rman restore and recover procedures. I read doc available in this regard and google as well. A few more questions unanswered in my mind.
    1. do the restore backup command restore controlfile also alongwith datafiles.
    2 database is running in noarchivelog mode. Suppose one of say users.dbf data files has been removed. control files intact. the same seq # is available since the last log backup. Now to restore the database, I use the following steps.
    1 rman > shutdown immediate
    2 rman > startup mount
    3 rman > restore database
    4 rman > restore database
    5 rman > alter database open;

    I'm wrong. This is the one. In this scenario, the steps above can be used.

    3. even when logseq is not available when the database is saved, I take the following steps.

    If after the last COLD backup is there not get command of newspaper (this means journal seq number is the same), so you can restore your database since the last backup and can retrieve it. And if thi does not need perform full restoration/recovery. At instead step 3 with DATA RESTORE (or RESTORE TABLESPACE USERS) file and step 4 instead with RECOVER DATAFILE (or RECOVER TABLESPACE USERS) and after that you can open the database by using ALTER DATABASE OPEN. If you have lost datafile users.dbf it means that this (tablespace) datafie has been automatically disconnected.

    3. even when logseq is not available when the database is saved, I take the following steps.
    1 rman > startup nomount;
    2 rman > restore controlfile autobackup.
    3.RMAN > change the editing of the database;

    6 rman > alter database open resetlogs;
    It is a right. can I adopt this procedure in my scenario.

    Yes you are right in this case. There, you have to restore/recovery complete database, because of your database running in NOARCHIVELOG mode. But after database restore (step4) you can just issue RESTORE database and can open with RESETLOGS options also. Also if you have incremental backups can run NOARCHIVELOG mode even RETRIEVE the NOREDO of DATABASE then you can open the database.

  • Confused about related files function

    Just got a new copy of Dreamweaver CS5.5, and I was crossing a line by David Powers - tutorial

    http://www.Adobe.com/devnet/Dreamweaver/articles/first_website_pt2.html

    Everything made sense until I came to this part:

    "If your screen is wide enough, the best way to work is in split view, using the functionality of the related files in Dreamweaver. Close the check_cs5.css by clicking on the X in its tab, leaving just open index.html'.

    OK, that is no problem, but I'm a little confused about using the Dreamweaver related files feature.

    "Click check_cs5.css on the toolbar of associated files just below the tab for index.html."

    Huh? Related toolbar files? The screenshots, it shows differ slightly from my interface, and I was wondering if maybe something has changed with the new version of Dreamweaver, or if I don't have a pref set correctly. Just below my tab for index.html are the buttons "Code, Split and Design." His shows "Code Source" followed of a button to the name of the css file.

    His splitter window resulting shows the design on the right side and the code css on the left. The best I can do is the design on the right and the code for the index on the left page.

    What I understand here. Any help would be appreciated.

    Thank you

    PflipX

    There is no related files in the HTML code in the screenshot above (no tag). Thus, any related files bar appears.

    You have not set the file check_cs5.css to the HTML page.

    The rule of #main_image has been created inside the HTML document rather than in the style sheet external check_cs5.css. See the definition of the rule in the new dialog box CSS rule.

  • Confused about the extension of the Sprite class

    Howdy-

    I learn programming with object oriented ActionScript and am confused about the class Sprite and OO in general.

    My understanding is that the Sprite class allows you to group a set of objects that you can manipulate all the objects at the same time.

    I explored the Open Flash Chart code and note that the main class extends the Sprite class:

    Base/public class extends Sprite {}

    What this lets you do?

    Also, on a related note, how to draw, say, a line once I extended?

    Without extend Sprite I could write:

    var graphContainer:Sprite = new Sprite();

    var newLine:Graphics = graphContainer.graphics;

    ...

    And it works very well. Once I have extend the Sprite class, I'm lost. How can I modify this code so that it still draws a line? I tried:

    var newLine:Graphics = this.graphics;

    My understanding is that since I extend the Sprite class, I should still be able to call its method chart (or property? I have no idea). But, he screams at me, saying "1046: Type was not found or is not a constant of compilation: graphs.»

    A number of things.

    First of all, I would not use this approach in your table constructor. Setting the width and height only makes sense if you adjust the width and height of the existing content, and the table (Sprite) does not at this time here. If you want to give the table a 'size', you could do it like this:

    public function Chart (width: Number, height: Number) {}
    This.Width = width;
    This.Height = height;
    put in a background invisible to this size:
    this.graphics.beginFill (0,0);
    this.graphics.drawRect (0,0,width,height);
    }

    There are other ways, including putting in a form or a Sprite of child as a child for the background so that clear will not erase the background of the chart. This way you could have properties for the background in your table class and update the background as a child DisplayObject instance... a few ideas to think to...

    Then, after that, your chart should be functional...

    Then back in your scenario, you could do this:

    import graphics. Table;

    Stop()

    var myNewChart:Chart = new Chart (300,200)
    myNewChart.render ();
    addChild (myNewChart)
