PatternRepository and only want only one instance of the application target to run

That's what I'm doing:

1 app is started manually from office.

2 registered PatternRepository point for a regular expression (be great if it only applied to my application, do not know how to do this, however).

3. If the RegEx showing in one of my ActiveRichTextFields, ApplicationMenuItem

4 ApplicationMenuItem pushes screen on stack.

I have most of this work except for step 4. creates a new instance of the application.

public class VocabApp extends UiApplication {

    private static ApplicationMenuItem[] _menuItems = new ApplicationMenuItem[1];
    static VocabApp app;

    public VocabApp() {
        this.pushScreen(new DictionaryScreen());
    }

    public static void main(String[] args) {

        //we only want to register/run when started from desktop
        if(args == null || args.length == 0)
        {
            _menuItems[0] = DictionaryScreen.synonymItem;
            ApplicationDescriptor appDesc = new ApplicationDescriptor(ApplicationDescriptor.currentApplicationDescriptor(), new String[]{"pattern-recognized"});
            PatternRepository.addPattern(appDesc,"{[a-zA-z ]*}",PatternRepository.PATTERN_TYPE_REGULAR_EXPRESSION,_menuItems);
            app = new VocabApp();
            app.enterEventDispatcher();
        }
        //This block will execute when one of our application menu items is invoked.
        else if(args != null && args.length > 0 && args[0].equals("pattern-recognized"))
        {
            app = new VocabApp();
            app.enterEventDispatcher();
        }
    }
}

I know that the code works as it should, I'm trying to figure out what to do:

//This block will execute when one of our application menu items is invoked.
        else if(args != null && args.length > 0 && args[0].equals("pattern-recognized"))
        {
            app = new VocabApp();
            app.enterEventDispatcher();
        }

.. .to make sure only one instance of my application is running at a time.

TIA,

Matt

Here, I'm a bit confused.

Your comparison of menu templates you run your application with the arg: "recognized cause.  An application is distinguished by the descriptor and the args.  If different args is different Application.  So this initiates a new Application.

But only once.  If you're still running, it does not start a new.

With this information, can you describe your problem yet?

    Hello, can someone help me with the installation of Adobe Flash Player?

    I tried too much to install but get this message "that only one instance of this application can run.

    I see all the Adobe apps, I tried to remove all of the adobe files and still nothing.

  • Only one instance of the same function call button?

    I have 4 instances of the same key on a single layer on a timeline of the "coverflow_mc" mc named 'ThatsMe_btn_a' to 'ThatsMe_btn_d' IE the same button, same position... He just changing the name of the instance on 4 key frames. Why he calls the function fine for button but not to b, c or d? There is a stop on each of these frameworks and I can see the SWF that it prevents the correct images.

    Picture 7.png

    function thatsMe() {}

    right = new Sound();

    right.attachSound ("right");

    right.start (0,1);

    trace (subTotal);

    }

    _root.coverflow_mc. ThatsMe_btn_a.onRelease = function() {}

    subtotal = 2

    thatsMe();

    };

    _root.coverflow_mc. ThatsMe_btn_b.onRelease = function() {}

    subtotal = 1

    thatsMe();

    };

    _root.coverflow_mc. ThatsMe_btn_c.onRelease = function() {}

    Subtotal = 3

    thatsMe();

    };

    the other buttons do not exist when your code runs.

    to remedy this, make sure that the other buttons exist when your code runs.  You can disable their visible property, so they cannot be seen.

    SQL * more command is

    After you give this command, if the first column in the output is called no., then SQL * more he will not show if it is the same as that on the line just above.

  • I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    Yes, you can have a one word title, by assigning a paragraph style title to this one word. No, you cannot change the text in a Table of contents, but you can change paragraph style font attributes (line) and add for example, a head of points between the types of OCD paragraph and page numbers. No part of the table of contents will not provide hyperlinks in exported PDF documents.

    When you look up in the menu bar, you can see the word iPages, or simply Pages. There is no product of iPages.

    Hi Please help me how to use cascade, if I don't have only one table with the customer name and the name of the product in the ADF... I use Jdeveloper 11.1.

    For the client, I used customer VO with client list to fill but to populate the product that I use bind variable PrODUCT_NAME select distinct from TABLE where client_name =: bindCustomer

    so first of all, I need to set the variable of liaison on behalf of the selected customer.

    Can you please tell me how to set this variable binding in this case.

    After you set the LOV to your product attribute, correspondting VO in the LOV will appear under view accessors.

    Change the accessor of the view, you will see the variable binding. Set its value to the customer field of the parent object.

  • Cannot install Flash Player as "only one version of this application can run.

    I had problems with Flash Player earlier today and decided to uninstall it (from Windows 7) and reinstall from scratch.  I uninstalled and tried to reinstall it but now I get the following message appears: cannot install Flash Player as "only one version of this application can run" I tried to uninstall I checked to see if there was still a program to install but it does not exist. I checked my files in Windows and there are several files called Install_Flashplayer _16x32... files. I assume that they are created whenever I tried to install Flash Player.  I thought to delete many files install FlashPlayer but decided to ask for help before taking this step.

    Browser: Firefox 35.0.1

    Windows 7 Home Premium

    64 bit OS

    I managed to install Flash Player and it works. I deleted all the installation files except one who did not want to be deleted, then I started to install Flash Player, until I got the message about the conflicting demands. I then used the Ctrl + Alt + Delete to open the Task Manager, then closed all tasks except the Flash Player one. Flash Player finished the installation. Then, I opened a TV Player in Firefox and was able to play a program that requires a Flash Player.

    Why don't I have to use the Task Manager to close applications. I don't remember the last time that I used it ut think that it was a year ago, when my computer would not shut.
