I try to convert it to version 2.0:
        text = new Text();
        text.translateXProperty().bind((scene.widthProperty().subtract(iv.layoutBoundsProperty().get().getWidth())).divide(2));
        text.translateYProperty().bind((scene.heightProperty().subtract(iv.layoutBoundsProperty().get().getHeight())).divide(2));
        text.setFont(Font.font(null, 24));
        if(image.isError())
            text.setText("Load Failed");
        else if(!image.isError())
            text.setText("Loading - "+ image.getProgress()+"%");
        if(image.isError()||image.getProgress()!=100)
            text.setVisible(true);
But I don't know what to do with bind. Could you help me?
content: bind (....)
visible: bind (...)
text.textProperty().bind( new When(image.errorProperty()).then(new SimpleStringProperty("Load Failed")).otherwise( (Bindings.format("Loading: %s", image.progressProperty())) ));

text.visibleProperty().bind(image.errorProperty().or(image.progressProperty().isNotEqualTo(new SimpleIntegerProperty(100))));

    If I choice a LUN to be on the area of SAS and dosent it box SAS has of space, for the lun hole, withs are 2 TB, and the free disk space on the boxes of is that of 500 GB, what happen next?
    The move of SAS drive the contents of the box to the other box and then move the lun I want to link to this box.

    The liaison will have higher priority than a lun without binding?

    Once you set up the binding of volume, reviewed operations are are automatically in the background.

    Sabari,

    You might have a problem with your plan file that has been changed after the redeployment and changes in JNDI.
    If you want to solve it:
    1. stop the managed server.
    2 delete the file plan '' element (with all of its content).
    3. start the managed server and check if the DbAdapter is in place (on the deployments of WL).
    If this isn't the case, redeploy from your EM console:
    Go to SOA_Farm-> the application deployment-> resources-> right adapters click DbAdapter-> application-> Redeploy deployment-> click Next-> checkbox selection:
    "Archive or directory exploded is the Server Enterprise Manager running"-> click Browse and navigate to the location of the DbAdapter.rar;
    (under $home/orasoa/Oracle_SOA1/soa/connectors)-> check a box to DbAdapter.rar and click OK. Do not change 'create a new deployment plan when deployment '.
    the configuration is created "-> Click - Next - redeploy.

    4. create the JNDI again.

    * Save a backup to plan before you change.

  • Liaison list

    Does anyone know if there is an easy way (as in the two lines of code max) to bind an ObservableList to the other, so that, when a change is made in that it is carried forward in the other?

    As an example of what I'm after, I have an ObservableList < person > on my controller which I want to connect to the ListView .some list < person >. I'm after something like:
    myListView.getItems().bind(myObservableList);
    I know I could write my own implementation of the link. I'm looking for the link out-of-the-box solution.

    Hi Zonski,

    the answer why are taken in charge of liaison for simple properties, but not for the collections is much simpler than you think: it was all simply not enough time to do it for version 2.0. I am currently working on the binding support for collections, and if all goes well it will be in version 2.1.

  • perfect in InDesign liaison

    How to set up a liaison in InDesign? The final size of the book is 5.5 "W by 8.5" h. roughly 10 pages with coverage.

    With a perfect hardcover book, you need to create a spine for the coverage, even with 20 pages.

    In a previous post, I noticed that you mentioned a spinal column, then you are aware of this requirement. With respect to the preparation, I would create two documents, one for the text - unique pages; one for the cover - spread including the spine.

    What are the advantages disadvantages of liaison n?

    Thank you

    Here are some comments I found:

    Although the link is a powerful mechanism, it is not suitable for all situations. For example, for a user interface complex in which individual parts must be updated, based on the strict schedule, it would be preferable to use a method that assigns properties in the order. Link runs whenever a property is changed, this isn't the best solution when you want the changes to point out only some of the time.

  • Basic questions of liaison

    Noob questions...

    Can you help me understand why the following won't work for me?  I'm so frustrated!

    MyComponent.mxml

    < VBox:etc... >
    [Bindable]
    public var url: String;

    public function setAndCallService (): void {}
    url = " http://localhost: 8888, blah, blah, blah ";
    serv. Send();
    }

    < mx:HTTPService id = "serv".
    URL = "{url}".
    result = "serv_result (Event); »
    resultFormat = "e4x".
    Fault = "serv_fault (Event); "/ >

    private void serv_fault(evt:FaultEvent):void {}
    trace ("serv failure occurred:" + error.text);
    trace ("url" + url);
    Error.Visible = true;
    }

    ... the rest of the file...

    What is happening is that the serv.send () is called and serv_fault is then called and the first track line indicates that no URL was given to the HTTPService component.  and yet the url gets printed by the second layout line correctly as "http://...blah/blah". ""

    If you have any time, may be able to explain why if I [Bindable] set for private property, why I also need [Bindable] by the get setter for this property (and which?  the setter or the getter?

    Thank you very much.

    In addition, if you have the time to explain all of the following...

    1. I know it's probably very stupid, but if the objects are passed by reference in flex, why do I need to bind?  Don't I always saw the single instance (and its updates) whenever I have a reference to it (in various components in which I spent the object)?

    2. If I have a private property in a component, a child component sees this private property, or should it be made public?

    3. If I put either private property [Bindable], why then would I also need to add [Bindable] to the get setter for this property?  And when should I define the getter for Bindable vs the setter?

    Thanks again for all the advance information.

    1. you may always use liaison. For example, in your example, I don't think that you need a separate URL or link property.  Just use the property of the HTTPService directly.

    2. the other components will not be able to see the private properties. So you could make public or expose it via get/set functions.

    3. because you actually define two different properties. Private property and the property defined by the get/set functions.
    You should probably only to the get/set functions public bindable (not private property). And no matter if the [Bindable] is specified before the get/set (in most cases), as it applies to the property, not the functions.

  • jdev11 - how the code filter additional liaison with radio buttons?

    Using JDev 11.1.1.0.2, ADF BC for model, ADF Faces JSF to view, deploy to WebLogic 10.3 appserver, database Oracle 11

    I asked for help (a do my work ask), that I'm the only developer JDev in our shop, and I looked at this problem too long and now have obscured the problem. I don't really want the answer (rather the skills needed to solve this problem), but it will ;-)

    Installation program:
    ExecwithParam base where the logic is stored in the AppModule. At this point, there is only a single binding TechID variable, which is passed to four of your different and updates the where clause and calls on each VO of the AppModule executeQuery. Works great so far!

    Need:
    Add additional time based filter: Group of buttons on the Radio for the last 30 days, 60 days, 90 days, choose a date. If choosing a date is sΘlectionnΘe, then the user selects a date with a date picker, and all records by this date are used.

    Support:
    There is a date variable in each query, and a common type of DATE filterDate may be added to each to filter with somedatefield > =: filterDate in each VO

    Thoughts:
    I like to break things in simple parts, so how about starting just the radio button.
    My thinking goes like this:
    Add another variable of filterDate liaison to each of your. Add this to the App Module.

    So, how can I set up a radio button so that I can get the value of the selected and then button that convert a SYSDATE - value and which use th e App Module logic? I continue to think of the big picture end of case and forget everthing. I know that's not difficult, but just ask me for some advice.

    At one point, I was thinking to add a clove of support to the option button, then wasn't sure if it was the best way and don't know how I would get the value in the AppModule. Part of the problem is that I came across a mental block. If I add the components that aren't linked data, as a selector of dates, or checkboxes, radio buttons, etc.. How can I get the values in the AppModule? I've seen many examples of data to related components, but do not know how to mix and match the binding with just a rich component controls base such as an input control. (This may better ask in a different thread).

    Finally, what of the big picture, the part about the addition of the datePicker - of ideas?

    Like cable TV, characters hosted - the kind that are related in my case the code! (Reference of American humor, must be familiar with USA cable TV channel (I'm addicted to the show House))

    Thank you, Ken

    Ken,

    A small correction to your last sentence - you don't want to refer to the support of the AM bean - you want to refer to the AM of the bean to support.

    If you want a very simple way: find the service for your AM method in the data control palette, drag-and - drop it on your page as a button JSPX. JDeveloper will automatically add a binding for the action in the pagedef. Then, double-click the button that results and create a new method of bean of support for her (in front of JDev, don't remember what we call the dialog box) - given the option, say JDev to put the code to link to you - then the resulting method should have the code that calls the method via the definition of the page. Simply add a bit of extra code to determine and set the date.

  • Challenge + liaison between in contact with

    Hi, Ive just receive my new defy + after using the normal challenge for a few months.

    I can't seem to find a way to "connect" my contacts, before I was able to connect for example facebook a contact contact in my address book so that they would appear as a single person.

    Im not sure if this is something android or what...

    Your help is appreciated.

    Steve

    The option is still there, but in a deeper menu.

    When you open a contact, press the menu button, then "edit contact", then the button menu once again, there is an option to 'join '. Once joined, you will find an option to 'split' the common contacts again.

  • ActiveX (MintController): Error 1057 after liaison with driver

    Hi, I'm relatively new to LabVIEW and have tried to order a Baldor servo motor using Mint of ABB ActiveX controls. I spend a refnum of the ActiveX container in an invoke node called "SetMicroFlexE100Link" which sets up the connection to the e100 driver Microflex we use. It works very well. Just after that, I send the same refnum to another invoke node to get the status of relay of the driver and the program generates an error (see attachment image for block diagram and messages). According to this tutorial, what I should be enough, so I'm puzzled as to why I get these errors.

    Any ideas on what's happening would be greatly appreciated. Thank you!

    Any help out there?

    Thank you.

    Vincent,

    Hello.  First of all, I wanted to mention that the NI GPIB library is not officially supported on systems time real LabWindows/CVI.  Your customers use it more in the earlier applications of CVI RT?  Can you tell me what features they use?

    While the NI GPIB library is not officially supported in CVI RT, errors of link that you see in CVI 2009 were not intentional.  You can tell your customer to copy the file gpib.lib to the location of the CVI 9.0:

    \National Instruments\\bin\msvc\gpib.lib

    the location of CVI 2009:

    \National Instruments\\bin\msvc\gpib.lib

    This should fix the problem.

    If your client has never repair or reinstall their installation of CVI 2009, they will have to make this change again.

    We intend to fix this in the next version of LabWindows/CVI.

    I have a card OR cameralink and want to handle the integration of a camera time using the controls of the camera series.  Is it possible to place orders of series using other software like MatLab (heresy I know)...

    My experience using MATLAB is absent, but if you can call the C API for IMAQ, then you should be able to do.  You can take a look at the help of the reference of the NOR-IMAQ function and specifically examine the functions of Communication series under features low level.

  • Where is the connection of the equipment to the TTL 0 on the expansion of liaison camera card OR?
