Is it possible to see what eventListeners currently exist?

I currently have a function in which an event listener is added (addEventListener (Event.ENTER_FRAME, create an Animation), but I call the function repeatedly in my program it gives me an error:)

ArgumentError: Error #1063: incompatibility of County of Argument on Projectv017_fla::MainTimeline / createAnimation (). expected 0, got 1.

Which I suppose is an error saying that this event listener already exists. Is this correct? If so, I was wondering if anyone knows if there is a way I can see if the listener already exists so I can write an if statement around the addEventListener method so that it creates that the event if listener is not already exist. I want to do this because I want to add and remove the event listener sometimes in my program because I don't need to always be running, but want to be enabled or disabled.

What is the syntax of your function? It should be:
function createAnimation(e:Event):void {}

If you want to check if the listener is:

hasEventListener (Event.ENTER_FRAME)

  • Firefox Sync on different offices-list of sync'd data-is it possible to see what we have sync in our accounts?

    Good day to you, members of the community!
    Have a very small but very important (I think, not only to me) question.
    It will be possible to see in https://accounts.firefox.com/settings?uid=etc what we sync'in (I want to say list of tabs, password section, session, etc.)?
    For example, we have submenu in 'History' - 'bookmarks of other devices.
    There I can see what bookmarks I have on the other device.

     But no way to see passwords, preferences, history, active session. Will the devs introduce such features in next versions of Sync?

    In addition, some possibilities to separate one single device from others? (I have 4 PCs, 2 of them I need to synchronize only the Favorites, tabs & passwords, the other 2 - only the bookmarks & tabs). Now, if I want to work with such a way, I need to create 2 different profiles for each pair of these PC synchronization.

    Sorry, the data saved on the server is encrypted and cannot be read by anyone as it is a server or even outside of a Firefox browser. The encryption is done on the upload to the server for synchronization and encryption is done when the data comes back from the server synchronization that happens in an installation of Firefox. The 'key' stays inside Firefox, it is not sent to the sync server - no one has access to this 'key', but you, and it's inside Firefox stored in the Firefox account credentials in the password field.

    As much as this is possible in the future - slim to no chance. To make this possible sync will have to be completely rewritten to change the encryption protocol. Something simply not developers to Sync ever wanted as a feature.

    Each installation of Firefox can be put in place for what is synchronized in Options > Sync. Select all or all - tabs, Favorites, passwords, history, modules, preferences.

    Separate what sync gets had however you want or use 2 different accounts of synchronization for each pair or the PC. You can even setup the same version of Firefox on a PC with separate profiles and have separate data on each profile with a separate for each profile synchronization account. But the combination you put 2 and 2 data synchronization, but 2 is becoming more in sync would have can be made with a single account. Deselect the option just data types, you want synchronized on 2 devices.

    In which your question 2nd separate or different add-ons by device; Deselect the option modules if you do not want add-ons that you want to synchronize or when they are synchronized to do not what they are deleted when you uninstall an add-on on another device (or deselect Add ons on the device that you want to remove an add-on so that 'action' are sent to the server synchronization, and then to other devices).

  • Is it possible to see what information shows on the LCD remote?

    Hello

    I was wondering if there is a way to see what information shows remote on the LCD screen.

    We have servers on an external data store and wanted to check a few errors on a server.

    Is it possible to do?

    Nothing that shows the actual error LCD text but the LCD is just a relay of messages stored in the recorded material that can be seen in OMSA.

  • Reader SDK: is it possible to see what text the user has selected?

    I use Adobe Reader SDK with c#, by looking at the characteristics of communication monitor.

    I can open a document in the reader and allow the user to the user the reader as select text tools, etc.

    Here's the problem: I want my application to know what text that the user has selected.  And I would like to know the name of the field that the user has selected, not only the text of the field.

    PIA of Microsoft Office went something like this:

    currentDocument.GetSelectedText ();

    Is it possible to do with IAC or javascript or plug in the Player SDK features?

    If this is not the case, can it be done with the Acrobat API?  I've looked through the two sets of documents and have not found what I needed.

    Thanks for any help!

    To write a plug-in for Adobe Reader, you will need to go through 2 separate steps.

    Step 1 - Download the SDK Adobe Acrobat (from here http://www.adobe.com/devnet/acrobat)

    and build your plugin against the Acrobat product, following the documentation to ensure that you use only the API that does not exist in the player program. The documentation tells you what version of the Adobe ACrobat program or Reader is required for the function and that the function can be called in Reader.

    Second step: apply for a certificate of reader allow your plug-in to be loaded by the player, the link is on the same web page as the link above. This step can be started until you have created your plugin, and I recommend that start you this process before you develop your plug-in like Adobe may refuse to give you the certificate in which case your development would be lost.

    Only once you have authorization form Adobe can you do your job of plug-in with the reader app.

    Once you have done these two steps there are a lot of people on this forum who can help you with specific problems you may encounter.

    If you are not sure of having the knowledge to build the plug-in, there are a lot of people that you can hire to create the solution for you.

  • Is it possible to see what is running in the system idle process?

    Too often, my laptop computer Windows 7 system slows down to a crawl. Lambasts the drive. And Windows 7 will be smart enough to know that things are bad, but not smart enough to know exactly which slows down things. It is simply asking if I want to use an interface that uses fewer resources.

    If I look at the screen in a program called Process Explorer, it is said that most of the cpu is used by a process called the system idle process. But you cannot stop this process. I need more information. What is past in the idle system process that slows down my system to a crawl, alarming even Windows 7 and stolen my hard drive - it's what I want to know.

    Anything that slows down your computer, it is not System Idle
    Process. "System idle process" is not at all no problem. Means "idle".
    "not in use." It's just the name of the system is done when
    It doesn't do anything. It's there just to make the total to add up to

  • Is it possible to see which computers are currently active on creative cloud on an individual account?

    I've traveled a lot with different host families and I've lost track which computers have creative cloud on it. Is it possible to see what computers it subscribes to or is active on? And is there a way to disable remote?

    Without checking the preferences menu in the desktop application of Creative Cloud on each machine there is no way for a client to see where they are currently signed. As Justin says that if you are connected on two machines and try to connect to a third computer, you are given the option of force (remote) disconnect from all other desktop platforms - but until then you do not have this option.

    To clarify what mentioned TSN, forms PDF that are used and saved by the application on a Mac are corrupt in a number of ways. When a form that has been corrupted by the Preview is opened in Acrobat/Reader, one of the symptoms is exactly what you describe. If you have access to Acrobat and the original form, empty, not corrupted, you can export the form data in a data file (e.g., FDF) and import the shape of FDF data in the blank form.

  • The search by using the search bar IS NOT to bring out all its on the page. He sees the shots, but don't highlight, so I don't see what it is.

    When I search a Word using the search bar, Firefox highlights all the hits on the page. (Sometimes it highlights some.)

    Apparently, he sees shots, because it climbs to everyone that I click Next. But it is not to highlight the successes. I don't see what Firefox has found.

    I'm afraid that it is a problem of Windows 7 (I'm not a fan of Win7).

  • Is it possible to read the voltage/current SMU after the closure of the original session?

    What is the method, or is it still possible reading the voltage and current of an SMU SMU-4138 measurements after the original configuration session has been closed?  I have a (relatively) long Teststand sequence that sets up the EMS to provide power to the ESA, then conducts tests and along the way I have to take the readings of SMU.  I was always under the impression, it is advisable to open and close the EMS quickly set up, but the 3-State programming model does not allow a way to jump into the running state of Init with channels VI, except through committed and engaged States and thus any stop in the process. The power measurement VI only works if you are in the Running State. Seems like a no-brainer, so what Miss me?

    It's BAD advice.  You open at the beginning of your program, you do whatever it takes with it inside your test (configure, read, etc.) program and you don't log off not until you stop your program.

  • If we do not have labview in system then is it possible to see the published web site vi?

    Mr President

    I'm new with labview software so I know more about it, please tell me about it.

    I want to know that I released a vi using web publishing tool then is possible to see on a system where we have no install LabVIEW. or if it is possible then how and what are the limits?

    For each computer that has not installed LabVIEW, you must download and install the free LabVIEW runtime engine that matches the version of LabVIEW of VI.

    Here is the link to the runtime LabVIEW 8.6.

    What version of LabVIEW you have?

  • Is there a way to see what's on my CF card before formatting when an SD card is also loaded into my 5dm 3

    I save raw to my large Jpeg on SD card and CF card.  If the SD card will stay in longer while I change maps CF.   I want to see my CF card to review before formatting.  This time, I eject the SD card to see what's on the map see  Is this possible?

    Thank you

    If you press the image playback, you can view the images on the two cards.

    If you look at the monitor when it s list shooting modes and the settings, press 'Q' and use the 8-way browser to highlight the area displays the icon for the maps 1 & 2 (#1 is the card slot CF.)  #2 is the SD card).

    Once the box is highlighted, use back line or main line to change what card is using the camera.  Press the 'Set' button to select your choice.

    When you press the 'play' blue button to review your images, it will make the selected map point.

    ALSO, if there is only one card in the device, the device will automatically switch on this map.  (for example if you eject the SD card, then press play (the image review), it will force the camera to display the images in the CF card, because it's the only card on the left of the camera.
