A component can use dataservice a main of the application?

I have several components that require the same dataservice and collection arraycollection to populate a control on each component.
Here's how my dataservice and arrayCollection collection are declared and populated
private var ds:DataService;
collection of private var items: ArrayCollection;
private var point: ItemTable.

items = new ArrayCollection collection;
DS = new DataService ("someDS");
DS. Fill (items);
Item = new ItemTable;

I would like to have this in my main application and then let my components to use. How can I call this dataservice and collection arraycollection of my main app for my components?

I think that using parentDocument.items, etc. or Application.aplication.items you could do that, but I wonder if the fact that they are private may prevent access. They might have to be public.

  • You can use migration assistant to transfer the time machine backup external hard drive?

    Hello. I just bought a new macbook pro with a 256 GB flash drive to replace my previous macbook pro that had a breakdown of all the systems. My problem is that I have a time machine backup that is greater than 256 GB (it's almost 450 GB) and I try to find out if I can use migration assistant to transfer all the content directly on an external hard drive, then move the content I want on my hard drive from the external hard drive? My goal is to let my music and photos on the external hard drive and for all port hardware I need for work.

    I don't have access to another mac with storage well enough that I have the old HD so could potentially be installed in an external enclosure and extracted files directly from there if it's easier.

    What I intend to do in the long term is to buy a big external hard drive network and put all my photos, music etc over there and use the laptop as expected - that is for files from day to day - then it will be just a short-term problem.

    Any advice would be really appreciated.

    Thank you

    Nick

    Migration Assistant is user to transfer data from one computer to the other.  If I read your post correctly, you want to copy your data from Time Machine on another HARD disk.  Thia may be useful:

  • How can I call or even use a class library inside the application that has been downloaded along with the app?

    Hi all. I have a question?

    I have an application and a library.  Inside of the app have a lot of calls of this library (easy to say my app that is dependent on the library).

    I tried the following scenario: in the main application I added logic to download the library programmatically. But something I missunderstood around that. So, I'm first to download my application that depends on the library then I thought to check in the constructor, if the library exists then activate the app if not then download the lib and restarts the device.

    My problem now is if I call a list of class of the library, then the app not working and would be lifted except that «the application contains errors of audit»

    So, how can I avoid this? or even

    How download this lib from the app and have other methods inside this app called library which is not yet downloaded?

    Thank you in advance. A sample will be apreciated.

    No, which would require a second application, such as an installer

  • You can use an external microphone for the animation of the character of adobe.

    I searched the internet and I can't find a way to use an external facilitator of adobe mic, so background noise is not as bad and my voice will be heard better, I used the mic in other software and it works as it should, so my question is can you use an external microphone for computers in the adobe character animation If so, how can you do?

    Yes, I use a USB microphone all the time. It should detect it automatically, but if not, you can go to the host character > preferences and select as input device.

  • You can use multiple computers to change the project of the elements of the first?

    I use first Elements 10.  I built a new project on my desktop, because the Office has a firewire port to capture video from my camcorder and my laptop is not a firewire port.  The project is stored on my home network.  I seem to be able to do editing very well using the desktop computer that the project has been created, but it will not directly charge on the cell for editing.  Premiere Elements is configured the same on both computers.  I guess my question is - Premiere Elements stores something on the computer on which the project was created on not stored on the network drive?    How can I fix the problem so that I can edit on my laptop? The laptop is a high-end Dell XPS with an i7 processor that I use for other projects of creation, so the capacity of portable computers is not a problem.

    Thank you

    Bill

    If I have a very fast NAS and the network, I found that to effectively edit a project, I want my project, and active at least an external FW 800 (same drive letter of the operating system on each computer) and an eSATA would be even better.

    I do all the time and my transportation projects between my laptop by the pool and work stations in the editing room.

    I've set up each project, with all assets (or Copies, as most of my goods are stored on the NAS), in a hierarchy of files for this project. With the drive letter set the same on every machine I migrate seamlessly and with zero problems. Mega-projects, with 1, in thousands of dollars in assets, loading quickly - unlike when working on the network, or of the SIN.

    But with a little planning, you should have zero problem.

    Good luck

  • Can I share my workouts with the application of the activity?

    I got the Apple Watch and love, that the design of the application of the activity, it is nice to remember to get up every hour to my work.  The problem is that I use a lot of apps to track my training because one size does not fit all, and I don't wear my watch $400 so I exercise (I have a striped Mio Alpha 2 for that).  So I have training in the gym followed my pace heart with Wahoo Fitness and followed my weight training with Strong.  After I finished my training, I synchronize Wahoo health or myfitnesspal app.

    Then I put on my Apple Watch and I do not see this workout on the implementation of the activity.  I'm just ignoring the activity app because it does not recognize the exercise I do.  How to share the workout with the application of the activity data?  Or, at least, how can I push workouts to my application of health for the purposes of the activity?

    Hello

    It is not currently possible to share training sessions with the app of the activity in the way you describe.

    The application of the activity titles activity undertaken while wearing Apple Watch. He that follows in general everyday wear and also reflects training sessions which are recorded through the application of integrated training (or Apple Watch of third party apps, if they are able to update the rings of progress).

    Health and fitness data (including training sessions) of Apple Watch, iPhone and any other source is grouped within the health on iPhone app. These data are not (and cannot currently be) back in sync app Apple Watch activity.

    If you want Apple to consider changing how data is shared between the health app and app activity, you can do so here:

  • Can not import a copy of the application to our workspace. The page is not found

    Hello
    We have an existing schema and workspace called track 2 and everything was fine. We could export a copy of the application of prod and import it under a different number, so we could test some changes.
    Then, we created a new workspace and schema called track3 and I tried to export a copy of prod and its import in track3 workspace.

    It gave the error:
    The page is not found
    The page you are looking for has been removed, had its name changed, or is temporarily unavailable.

    The URL, he found himself on after that the error was http://ourServer:7778/pls/apex/wwv_flow.accept

    In troubleshooting, we went back track 2 environment and cannot import copy of this old workspace more either.
    This has happened before on another post (contract), I was on and fixed it himself.
    Then we tried to bounce the server HTTP, did not work. I tried to bounce the database server has failed.
    What can do us?

    Please, any help is appreciated. Bill

    To debug the problem using SQL * Plus, you must connect as KMX2 in the production database. If the script fails, there will be no harm. You can remove the validation of the end of the script and replace it with a restore where the script is not and you want to ensure that there are no changes to your db prod.

    Don't you think that the version 3.2 upgrade would fix our problem?

    I do not know.

  • Can CSA produce an inventory of the applications?

    Can produce CSA and an inventory of the applications installed on a protected host?

    Yes, if you enable investigation of Application deployment, you will get an inventory of installed applications (what you see in Add/Remove programs on the PC).  In addition, CSA also follows the processes running on the machine, then you will see applications that are not "installed", but run as just transient process.
