binding of events and get accessor function

I found this snippet, when I was walking in a Flex3.6 project:

                [Bindable(event='currentPageChanged')]
          public function get currentPage ():int {
               return this._currentPage;
          }
          
          protected function set _currentPage (value:int):void {
               if (this._currentPage == value){
                    return;
               }
               this.__currentPage = value;
               this.dispatchEvent(new Event(BookEvent.CURRENTPAGE_CHANGED));
          }

          protected function get _currentPage ():int {
               return this.__currentPage;
          }

What is it meant to do by declaring an event that can be bound above the getter function immediately?

Thank you very much.

Here's the documentation:

If you omit Bindable in Flex - change of ownership will not by the application.

Apart from Flex, it makes no difference for him is not used in any case.

  • Get accessor can be linked

    I have a getter bindable which returns an ArrayCollection collection.

    [Bindable]
    public function get myArr():ArrayCollection {
         return _myArr;
    }
    
    public function set myArr(value:ArrayCollection):void {
         _myArr = value;
    }
    

    documentation:

    ""a call to ArrayCollection.addItem() , ArrayCollection.addItemAt() , ArrayCollection.removeItem() , and ArrayCollection.removeItemAt() all trigger data binding " "

    The Bindable Get accessor will trigger an event when I do this?

    _myArr.addItem(myItem);
    

    No, it won't, as _myArr is a private property. You must use myArr.addItem (myItem)

    No, var age: int = classname.age; will be re-run.  But lets think about that for a second, when classname.age is changed, what is the State of 'age', he might be out of range, or specify a different value, and so on.  DataBinding usually manifests in mxml components tied to the data they represent.  If you want to link 'age' classname.age then you must use BindingUtils and implement binding yourself, it is not difficult but can be weird with its syntax in the beginning.

  • Get-view datastore and get-function data store

    Hey, my first time posting here.

    Creating a function which takes as input pipeline and processes that each entry through process in a function. I want the function to be able to take the 'get - view - viewtype datastore' and 'get-datastore' as input.

    Obtained in what concerns obtaining the opinion of the GET and get-datastore work separately in the service, but when I want the function to be able to take one or the other input that I can't make it work.

    Here is the function at this moment, not really work for one of the entries.

    Check the type of the object in the variable $datastore.

    Something like that

    if($datastore -is [VMware.VimAutomation.ViCore.Impl.V1.DatastoreManagement.VmfsDatastoreImpl]){
    # From Get-Datastore
    }
    elseif($datastore -is [VMware.Vim.Datastore]){

    I no longer get suggested words when composing a message text on my iphone 5.  How to get back to get this function works

    Make sure that the text is on. You can do this on the keyboard (if you have several) by pressing and holding down the button to change between them.

    Alternatively you can go to settings > general > keyboard and make sure predictive is turned on (the switch must be green).

    If you see the image below, press the small white bar above the buttons T and Y and slide upward slightly.

  • the event structure cannot combine with other events and run only once

    Why it will always get stuck when I combined the 'new user add' event to the event of 'Login '?

    It works for me when I separate the two, but the 'Add a new user' button can work but only once for the structure above, program will be blocked on the second time that I press the button "add a new user".

    It has already been said, you must use that a single structure of the event and not 2. Also, avoid using local variables (better store data in a shift register and not in an indicator) how you do it, it can cause bad racing conditions.

    Actually here you just don't another data storage since you have a file. Don't store data file to the root of the C drive, you do not have write permission. Use the default data folder or the folder of the application.

    I have attached a simple example. I guess that's a work at home? Please make my account help: try to understand why your VI does not work and try to find a solution by yourself. Modify my sample and play with him. This is how you learn LabVIEW. If something is not clear, post here, and we can explain/help.

    Edit: has the 'connection' event, I don't check against whether the file exists or not. Difficulty of this part, gives too little practice.

  • Windows does not correctly - open cursor freezes and gets to abnormal termination

    Cursor freezes. Then I can just turn off the computer at the tower. Windows then reopen correctly. Sometimes I'm asked to select 'normally open', sometimes prompted to opt for the option "repair". Sometimes takes up to 15 attempts before getting the chance.  Then the process repeats itself afterwards. There is nothing wrong with the cursor. Help!

    The best way to combat the freeze is to be patient and select Ctrl + Shift + Esc to bring up the Task Manager. Click on the Applications tab, place the cursor on a running application, and then click end task. Be patient as the task manager should have priority over a problenmatic that runs application. It usually does, but he needs time. If you continue to use the Power On / Off button you will make things worse.

    Can you identify which application is causing the problem?

    Event Viewer reports

    1. normally, when an error occurs on your computer looking in Event Viewer should be your starting point to find a solution. More related system errors are recorded and get an exact copy of the relevant report is important. Unfortunately, is not easy to understand reports and most of the users computer need help with their interpretation. I have to say later interpretation.

    2 Event Viewer includes three main newspapers of Windows. Here's the Application, security, and system. For purposes of troubleshooting system is by far the most important.

    3. to access the system log, select Start, Control Panel, administrative tools, Event Viewer, in the list on the left of the window select Windows and the system logs. Place the cursor on the system, right click and select filter current log. Check the front of the error and click OK and see you only reports errors. Click the Date and time column header to sort. You may need to click a second time to see the last report above.

    4. a tip for posting copies of error reports! Run Event Viewer and double-click the error you want to copy. Click the copy button to place a copy in the Clipboard and close Event Viewer. Now start your message and paste it into the body of the message. Make sure that it is the first dough right out of the event viewer.

    5. He cautioned against three types of reports, information, and reports errors. In most situations, it is the error reports that offer the best information but sometimes WARNING reports provide useful clues.

    6. all reports have stamps date and hour and when troubleshooting, it is important to focus on the latest reports. Reports of studies from the point when the computer is started, and then check if a similar report appeared in the previous session. If errors do not repeat investigation as to why they happen is wasted effort.

    7. in the individual reports the most important information is the event ID and Source such as these help when looking for help on the internet. The description is just as important and copy the exact text to use as search criteria greatly helps achieve better results when using Google. Not paraphrase descriptions when other people asking for help.

    If you have any software backup as totalrecovery pro 9 or norton ghost, they prevent you from creating a manual restore point.  I have 9 pro full recovery and everything I do is to disable the Recovery Manager when I want to create a manual restore point.  There is no problem with system restore points created they work very well it is the manual of who are the problem.

  • Complete used Windows 7 install and get a physical picture of the blue screen

    Monday my computer was play music on a hard disk when it entered into sleep and started screaming.

    It meets all of the keyboard controls, so I reset by holding down the power button.

    Since he refuses to load windows 7 but also put white dots on my screen at regular intervals when the system goes through its parameters.

    He enters the window of windows beginning it loads the logo entirely with three batches of 3 blue stripes run from top down in the background, but don't effect the logo or the words at all but then says that there is a windows error and can not load.

    Asked to do a system repair that may be defective and so I tried to reinstall the operating system instead. The screen has once again a lot of blue lines wavy background through the normal screen of windows 7, which is at the back of the repair of the system window.

    I wipe the partitions drive and begin the installation. It goes through the whole plant, until this happens at "Completing installation" then it blue screens says physical dump but blinks in and out and can not read. The rear crossbar start load windows logo, then opens pop-up box saying "installation could not complete due to an unexpected error, please click ok to reinstall windows" and then he turns around and does the same thing again and I'm going around and around.

    The graphics card can't be gone because on some screens (like the logo screen to motherboard to get into the Bios etc) there is no error at all, it seems to be nothing to do with black Bios windows or windows screens it puts these error lines. Also the motherboard doesn't mean that there is an error or a fault with it either.

    I checked and reformat the hard drive and it works without error.

    Tested my 4 GB of ram, who also spent and no mistake. There's nothing wrong with the power supply.

    I'm concerned, it's something with my card graph and map mother, or is - something in the BIOS?

    WD - 500 GB HDD

    Corsair XMS3 - 4 GB of ram (2x2gb 1600 mhz)

    Asus P7P55D-E motherboard

    Sapphire Pure 950w

    Processor i5

    I don't know what to do other than replace the motherboard?

    I CAN'T get to the office so no start menu stuff please as I can't do it. So I can not download the minidumps or update my system. Unless someone knows how can I update the Bios and drivers without current initialization?

    Thank you for your advice. Thanks to everyone for their advice. I got my system running a bit once the new parts increase.

    I did some experiments.

    I put my brothers old graphics card in my computer and loaded with the operating system without problem.

    Does not perform all the updates no bother. I tried my card on day of reclamation, but once again before you complete the download, it crashes and we're back in the loop.

    So I think that the map was officially.

    I ordered some new parts and make and upgrade with certainly a new graphics card.

    But it works now.

    So, if anyone has the same problem.

    Find another computer and write a check for the new bios for your motherboard and do a flash upload if your motherboard has this function as mine did.

    Get out of your hard drive and get the data off it by plugging in a new computer.

    Reformat and reinstall the operating system.

    If you have problems with your screen such as lines and points like I did then your operating system won't load and you will get "nvlddmkm.sys" your graphics card is totalled.

    If she does not do and update on your graphics card.

    That's all you can do.
