  It also seems that you have an incorrect class here.  You are detailNews method is in your ApplicationUI class, but you are trying to call on the ListView, not your ApplicationUI object.

  I recommend having a read through our documentation of signals and Slots , which should help you to achieve what you're trying to do.

• Resize Images coded before adding it to a BitmapField

  I will have questions my image re-sizing. I click on an image using the camera and store it in the images folder. When I retrieve the image I see the picture on the screen but I want it to be smaller, since it occupies the entire screen and more and I have to scroll down. I added the code to scaleImage (see linebelow code red) but no luck. I'm doing something wrong? -Thank you.

  EncodedImage image = EncodedImage.createEncodedImage (dataArray, 0, dataArray.length)

  image.scaleImage32 (1, 1);

  BitmapField bitmapField = new BitmapField();

  bitmapField.setImage (image);

  Add (bitmapField);

  fixed32.tOFP's it. Thank you

• Error 104 when call pushscreen

  Hi all

  I am a beginner with RIM API, and I am developing a small application with Eclipse.

  In fact, I have a 'class hand screen', which shows my home screen, no problem for it.

  I have a button when I click on, it displays a menu with many items, I would like that this element (called 'send') show me a new screen, simply. Yes, it's simple I know but I ' v still a real problem with one exception and I don't understand why...

  Here, the function in my 'main' class who attempts to call one method from another class

  public boolean onSend(){
  
  testecran te = new testecran();
  te.affiche();
  return true
  

  and there, my class 'testecran '.

  public class testecran extends UiApplication {
  
          public void affiche() {
  
              testecran theApp = new testecran();
              theApp.enterEventDispatcher();
  
              };
  
              public  testecran(){
  
                  pushScreen(new UserInterscreen());
              }
  
      }
  
      final class UserInterscreen extends MainScreen{
  
          HorizontalFieldManager _fieldManagerTop;
          VerticalFieldManager _fieldManagerMiddle;
          HorizontalFieldManager _fieldManagerBottom;
          BitmapField _bitmap;
          Bitmap _logoImage;
          BasicEditField _input;
          int displayed = 0;
  
          public UserInterscreen() {
          super();
          LabelField title = new LabelField("Welcome",
          LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
          setTitle(title);
  
          }}
  

  I tried to call an alert of dialogue and it is work... then there is a problem with my "pushscreen" function, I think...

  When I try to run in the Simulator, when I click on my question, in my menu, i ' v this error exactly:

  App error 104

  Eception: RuntimeException

  After many changes, I don't know why it does not work...

  Like SImon, I'm confused by the code you are using.

  I'm working on writing some tutorials designed to initiate people in the development of Java on the BlackBerry.  Attached are the first two (in fact, there is an introduction one but you don't need that).  Remember that they have not officially reviewed by anyone yet so treat with caution.  But I hope that you find them useful and they explain some of the concepts that you seem to be missing.

  At least, I think they will help.

  Please read, review and comment on tutorials and if they answer your questions.

  See you soon

  Edit:

  Attachments deleted.  I hope I can publish soon.

  Thank you

  And which line in your code, you are in when this happens?

  Also all the code you pasted is commented on isn't she.  If you added the comment lines?

  I take that you actually remove all of this but it's confusing isn't.

  But please do not copy and paste your code here.  We are not paid to wade through your code.  Rather try to prove too small a section of code as possible, that shows the problem.  This means not just modify the code you.  If you cannot debug your code and need help, then I think that too is that you benefit to help us. You can do this by reproducing the problem is an autonomous small section of the code.  Then it is easier for us to review and also possible for us to test.  Ok?

  Finally, I think you make too much treatment in the paint.  Paint is often called and if you do as little as possible in there.  He shouldn't layout fields, get values, get the bitmaps and others.

  Here's a simple example:

  Replace this:

  myMap = new MapField (Field.FOCUSABLE) {}
  protected void paint (Graphics graphics) {}
  Bitmap myIcon = Bitmap.getBitmapResource ("stadium_icon.png");

  with this

  myMap = new MapField (Field.FOCUSABLE) {}

  Bitmap myIcon = Bitmap.getBitmapResource ("stadium_icon.png");
  protected void paint (Graphics graphics) {}

  and now you recharge a bitmap for each painting, do you this only once!

  For even if you need paint the location later, when he changes you must reset the field with Bitmaps that you want (for example), and then invalidate the field so that it gets repainted.  So you do that once when the situation changes, not whenever you call paint.

  I suspect that a change like this will solve your problem.

• BitmapField does not display an image bitmap. In fact, it does not display anything at all...

  My problem is simple and fast. I am probably just a stupid mistake, but the BitmapField component does nothing and does not display the bitmap image. I first tried to display a Bitmap using its setBitmap (bitmap Bitmap) method, which did not work. Then I tried to use it's method setBitmap to the Builder, who did nothing at all no more. Then I tried to use setImage using an image encoded if nothing happened again. Yes, both the encoded image and methods of Bitmap.fromBitmap that make new Bitmap objects and EncodedImage POINTENT to real images in my project folder. So what I am doing wrong, I forget to call a method in needed or what? I use Eclipse with the plugin and I use the Blackberry 9550 Simulator.

  First of all, your use setSpace is incorrect. What you are doing here are to define a space around the bitmap image - in this case, the space is bigger than most of the screens, which will ensure that your bitmap image is not actually on the screen. See the description of the API in the javadocs.

  Second, you SHOULD check the return of getBitmapResource(). If it returns NULL, then the resource was not available. What you're doing here can hide a problem.

• Bugs in EncodedImage and BitmapField

  Hi guys,.

  I was badly put to scale down a large image (1600 x 1200) taken

  w / BB to fit on the Pearl camera. I use api EncodedImage for scale

  and send it to BitmapField. But this cause a system reboot. When I

  use BitmapField with the image without scaling, I will get an out of memory

  exception and my app will not work again.  BitmapField will work only w /.

  small images.

  I had a problem with that, and it seems that, on some devices, an error arithmatic will cause the device to reboot. This is probably due to an argument of the wrong size on the Bitmap you generate. Values getWidth() and getHeight() will return a value of Fixed32 with some height and the width of the image resizing product (even if it is false). I solved the problem by encapsulating all the numbers in a Fixed32 object and using the Fixed32.div () method.

  E.g.

  Bitmap b = EncodedImage.getEncodedResource("myImage.png").scale32 (Fixed32.div (Fixed32.toFP (1600), Fixed32.toFP (w_scale)),)

  Fixed32.div (Fixed32.toFP (1200), Fixed32.toFP (h_scale)));

  Hello

  I found the error.

  It's in the URL sent by the server.

  The URL consisted of http://google.com

  But the format required to retrieve the image on several device would be http://www.google.com.

  Thanks for anyone who tried to help him.

• Not able to focus BitmapField

  Hi gurus

  I searched for this error but have not been able to find a solution.

  I have a HorizontalFieldManager where I add BitmapFields. These BitmapFields have FOCUSABLE, no problem with that style.

  What I'm trying to do, it is only when the user focuses on a different field, outside the HorizontalFieldManager and then returns to the HorizontalFieldManager, enforcement "remembers" field was centered in the HorizontalFieldManager, much as the menus of Twitter and Facebook on their BB applications.

  To do this, I'm saving SelectedIndex when the Manager is blurry:

     protected void onUnfocus(){
          BitmapField focusedField = (BitmapField) getFieldWithFocus();
          if (focusedField != null) selectedIndex = focusedField.getIndex();      
  
          super.onUnfocus();
      }
  

  It works very well, I'm able to get the selectedIndex property. So what I try to do next is to focus this field when the manager gets concentrate:

   protected void onFocus(int direction) {     
  
          BitmapField fieldToFocus = (BitmapField) getField(selectedIndex);
          if (fieldToFocus != null) fieldToFocus.setFocus();              
  
          super.onFocus(direction);
      }
  

  I see that fieldToFocus is recovered succcesfully, is not null and the selectedIndex property is valid, but when I run the method

  fieldToFocus.setFocus()
  

  It is for me a StackOverflow Exception.

  I tried many other ways and have not been able to understand how to fix it. I also tried to comment the last line on the onFocus event: super.onFocus (branch);

  But it does not work.

  Help, please!

  a Board exception stackoverflow on a loop without end. maybe onFocus is called again when you run setFocus? Avoid it along with a check on the target area.

  I would also call great.

  Hello

  I think that the string you give to the new Image (string) must be a URL, not a single file path.

  So if you have a file, it would be something like:

  File file = ...;
  Image image = new Image(file.toURI().toURL().toExternalForm());
  

  Hope this helps,

• Uninstall software update Apple says error in seller contact package package unstaller

  Try to get itunes working to make a backup of my faulty iphone before repair.

  First-itunes does not start says error. I'm trying to fix it, who said success but same error when you try to start it.

  Then uninstall completely worked. Then reinstall that seemed to be over except for a message "an older version of Apple software update already exists" then he went down and install itunes apparently had not been completed.

  Then I try to remove the update from the apple software and executed by an error in the installation program - it says there is an error in the installation and contact the supplier of the installation package. Same error if I run the uninstall command line program.

  Try to repair the Apple Software Update of programs & features Control Panel and then try to update iTunes again.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

  I'm new to apple and get a syntax error when you use SUMIF.  In my table, I just need column F to test the value of column E.  If it is greater than 0, then divide by 20.  Thank you!

  In cell F1

  = E1/if(E1>0, 20, 1)

  fill down as needed

• An error in this Applescript that I can't understand

  Hi, I searched some forums and found this script below which I modified. It works great except for a single statement:

  runScript If = 1 then number error -128 I want the script to do is, when a USB drive is mounted and is in the ignoredVolumes as "USB Untitled" I want the script to stop. What I can't understand is, runScript is set to 1, "Untitled USB" Monte, runScript is not changed, why don't the script stops with an error "user cancelled"? On the other hand, if a key USB Monte is not in the ignoredVolumes, runScript is set to 2 and copy the file I want it. What hurts? It's probably something that will be very obvious when I see the answer.

  Thanks for any help with this problem,

  Mike.

  The way in which your external block If is currently based, the script can't do anything when this book is in the ignoredVolumes, it can not yet test the runScript value. Try something like this:

  If the present book is in the ignoredVolumes then

  game runScript to 1

  on the other

  if (the present book as text is not '. ') DS_Store') then

  if there are alias (POSIX (' / Volumes / "& the present book) as text file ) then game runScript to 2

  end if

  end if

  
  

  Of course, you need to remove a "end if' the end of the script.
