• How to register for an event when the device is connected to the PC in USB mode or sync

  I develop application on blackberry with phonegap.

  I want to hear event when the BlackBerry device is connected to the PC by USB MODE or sync.
  I saw mediagallery and applications Filemanager showing the dialogue that the application cannot be used when connected to the PC in USB mode.
  I want to display dialog similar to my request.
  Can anyone please help on how to do it.

  I saw blackberry webworks API

  public static Boolean blackberry.system.isMassStorageActive)

  who says if massstorage is active or not.

  But I can't keep on request this API every time. I'm looking for an API that gives me the reminder.

  Can you please help.

  On the side of Java, this can be done by implementing a FileSystemListener and the rootChanged method:

  public void rootChanged(final int state, String rootName) {
      if (rootName.equalsIgnoreCase("sdcard/")) {
          if (state == FileSystemListener.ROOT_ADDED) {
              /* SD Card is available. */
          } else if (state == FileSystemListener.ROOT_REMOVED) {
              /* SD Card is not available. */
          }
      }
  }
  

  I was not able to find a corresponding WebWorks API or API community well, so I think you need to create your own custom extension to implement this feature of the listener.

• How can we save the event when Photoshop is stopped?

  Hi all!!

  I have to perform actions on the record of events of a document. I had no problem doing the same thing. But, in the course of the different tests save event trigger scenarios, I fell on the situation in which a document without title is open and the user closes Photoshop. At this point, Photoshop prompts the message "do you want to save the document? Regardless of the user's selection ('Yes' / 'No'), the plugin is unable to obtain registration event, perhaps due to the termination of the application. I get the message of kSPInterfaceShutdownSelector directly. Don't stop to save event reminder.

  How can I make sure that my save event callback is executed each time a user saves a document?

  Thank you!

  You must analyze the close event descriptor. Locate the key keySaving

• How to get an onChange event when the user clicks a button?

  Hello
  
  I'm new to APEX and have the following problem:
  
  Implementation:
  There are two text elements, one for the zip code and the other for the city.
  
  When you change the zip code, the city will be changed accordingly with the data from the database.
  
  I've implemented an "OnChange" in the zip code for this element.
  
  Problem: The on change event is executed only if the user leaves the text with a tab element or click on another piece of text.
  
  When it hits the "next page" button directly the city is not changed.
  
  Pointers for a solution please.

  Well, depends on how your button is built but, in any case, Javascript supports the onclick event on the element for each HTML.
  Model based buttons are often created as links using the indicator A, but which prevent you from adding an onclick on her event.
  In this case you must choose if you want to cancel the default action, or you prefer to perform the default action (the doSubmit in general) as well as the onclick event.
  The order of execution is
  1. the onclick event
  2. default action

  If you return false from the associated with onclick the function Manager, the default action will be canceled if you return true, he will be executed.

• How to listen to a closed screen event

  Hi, do achieve the example that I gave to 2 screens, I would class to know when App screen1 is closed and act at this time, how can I do this?

  import net.rim.device.api.ui.UiApplication;
  
  public class App extends UiApplication{
  
      public static void main(String[] args)    {        App  app = new App();        app.enterEventDispatcher();    }    public App()    {        pushScreen(new Screen1());        pushScreen (new Screen2());    }}
  

  Screen1.Java:

  import net.rim.device.api.ui.component.LabelField;import net.rim.device.api.ui.container.MainScreen;
  
  final class Screen1 extends MainScreen{
  
      public Screen1()    {        super();         setTitle(new LabelField("Screen1"));    }    public boolean onClose()    {     setDirty(false);      return super.onClose();    }
  
  }
  

  Screen2.Java:

  import net.rim.device.api.ui.component.LabelField;import net.rim.device.api.ui.container.MainScreen;
  
  final class Screen2 extends MainScreen{
  
      public Screen2()    {        super();         setTitle(new LabelField("Screen2"));    }    public boolean onClose()    {        setDirty(false);      return super.onClose();    }}
  

  Declare an interface:

  public interface ScreenClosedListener {
  
     public void notifyScreenClosed(MainScreen screen);
  
  }
  

  Add features to the Screen1 class.

  import net.rim.device.api.ui.component.LabelField;
  import net.rim.device.api.ui.container.MainScreen;
  
  final class Screen1 extends MainScreen {
  
      private ScreenClosedListener listener;
  
      public Screen1(ScreenClosedListener listener) {
          super();
          setTitle(new LabelField("Screen1"));
          this.listener = listener;
      }
  
      protected void onUndisplay() {       listener.notifyScreenClosed(this);    } 
  
      protected boolean onSavePrompt() {
        // if you want to always close the screen
        // without questions just return true
        // there is no need in setDirty(false)
        // in onClose() method
  
        return true;
      }
  }
  

  Add features to the App class, make the screen closed event listener

  import net.rim.device.api.ui.UiApplication;
  
  public class App extends UiApplication implements ScreenClosedListener {
         // compose Screen1 instance and pass to the constructor    // the reference to the App clas    // which is ScreenClosedListener implementation     private Screen1 screen1Instance = new Screen1(this); 
  
      public static void main(String[] args) {
          App  app = new App();
          app.enterEventDispatcher();
      }
  
      public App() {        pushScreen(screen1Instance);
          pushScreen (new Screen2());
      }
  
     public void notifyScreenClosed(MainScreen screen) {
  
           // check the event source object         if (screen==screen1Instance) {     // act accordingly here     }   }
  
  }

• How to raise an event when a file is created.

  Hello!
  I need labview wait until a file is created in a certain folder (by the other program) and then to perform a task.

  Is this possible?

  I have no idea how to implement it.

  Thank you!

  Use the file Info feature.  From time to time, repeat until you do not get an error.

  I saw an example somewhere where someone used .NET to get an event when a file has changed.  I have no idea where he is or how it was done however.

• on my key board when I try to type a letter that has a number or a symble on it it type the number or the symble how to fix this?

  on my key board when I try to type a letter that has a number or a symble on it it type the number or the symble how to fix this?

  Make a lot of assumptions here...

  Keyboards only I know who have numbers/symbols on the letter keys would be a laptop or netbook without a numeric keypad.  Assuming that this is the case, the most likely cause is that you have the 'digital Locks' active.  To return to a regular keyboard, you must disable the NumLocks.  On a laptop, how to do varies from a Builder (in other words, if that doesn't work, download or consult the manual of your computer)... but usually this is done by pressing the "FN" key at the bottom of the keyboard while pressing the 'Num Lock' key, which is usually on the box at the top right of the keyboard.

• How to navigate to another screen when I click on BitmapField what listener I have to use?

  Hello

  My requirement is I need to add icons to image in horizontally and when I click on the icon of the image it must navigate to specific screen, so I use BitmapField to display image icons and I added to HorizontalFieldManager but how to navigate to another screen when I click on BitmapField (the image icon) who listens to I have to use?

  Please suggest useful links.  Advanced thanks.

  Concerning

  Sunil.G

  Personally, I prefer to do the treatment that you need directly on the ground rather than using a listener.

  The following code is an example:

  BitmapField bmf = new BitmapField(Bitmap.getPredefinedBitmap(Bitmap.HOURGLASS), Field.FOCUSABLE) {
      protected boolean navigationClick(int status, int time) {
          Screen myScreen = new ();
          UiApplication.getUiApplication().pushScreen(myScreen);
          return true;
      }
  };

  How can I default to LR, when clicking on the cloud creative app. ?

  Hi Ron,

  What do you mean exactly? The creative cloud App is just that - a stand-alone app that manages your subscription CC, including the app updates and active such as files and fonts.

  You want an icon to click to run Lightroom? In this case, you would start Lightroom (not CC App) and either "pin to taskbar" (Windows) or "Keep in Dock" (Mac). If you need help doing that, just tell us what operating system you are running. If this isn't your question, please clarify what you are asking.
