  • "too many threads error" in blackberry OS-4.5

    - by SWATI
    hi in my application i have 20 icons(bitmap fields) on the home screen When i click on any icon an HTTP request is made in a separate thread. I have used invoke later method wherever necessary to take care of multi-threading problems. But still the number of threads goes beyond 16 and an error pops up indicating too many threads error and applications needs to be restarted!! can anybody tell me how to destroy these threads when they are no longer in use. I don't understand why they don't destroy on their own as usually they do.

  • Blackberry (Java) - Setting scrolling be not focused on objects on the screen

    - by paullb
    I have a mainscreen which currently scrolls (and I have the arrows on the right) but the scrolling seems to be focused on the ButtonField objects that I have on the page. Is there any way to set the scrolling to be non-focused scrolling (moving a few pixels each time). Is there a way to set this? Other ideas I have had (which sound hacky so I want to avoid): - Placing NullFields around to scroll - Manually listening to the trackwheelRoll event and moving appropriately

  • RIM blackberry Record 3GP video

    - by pankaj_shukla
    Hi All, I am writing an application that can record a 3GP video. I have tried both MMAPI and Invoke API. But have following issues. Using MMAPI: 1. When I record to stream, It records video in RIMM streaming format. when I try to play this video player gives error "Unsupported media format.". 2. When I record to a file. It will create a file of size 0. Using Invoke API: 1. In MMS mode it does not allow to record a video more than 30 seconds. 2. In Normal mode size of the file is very large. 3. Once I invoke camera application I do not have any control on application. Here is my source code: _player = javax.microedition.media.Manager .createPlayer("capture://video?encoding=video/3gpp&mode=mms"); // I have tried every encoding returns from System.getProperty("video.encodings") method _player.realize(); _videoControl = (VideoControl) _player.getControl("VideoControl"); _recordControl = (RecordControl) _player.getControl("RecordControl"); _volumeControl = (VolumeControl) _player.getControl("VolumeControl"); String videoPath = System.getProperty("fileconn.dir.videos"); if (videoPath == null) { videoPath = "file:///store/home/user/videos/"; } _recordControl.setRecordLocation(videoPath + "RecordedVideo.3gp"); _player.addPlayerListener(this); Field videoField = (Field) _videoControl.initDisplayMode( VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field"); _videoControl.setVisible(true); add(videoField); _player.start(); ON start menu item Selection: try { _recordControl.startRecord(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } On stop menuItem selection: try { _recordControl.commit(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } Please let me if I am doing something wrong. Thanks, Pankaj

  • jQuery on iPhone/Android/BlackBerry

    - by Floetic
    I don't have any of the devices to test at the moment. I guess I'll start using the emulators later on. We're looking to offer mobile support. I was wondering how jQuery or even javascript renders in their respective browsers. What works? What doesn't? Any tips? Advice?

  • BlackBerry - Convert EncodedImage to byte []

    - by user324884
    I am using below code where i don't want to use JPEGEncodedImage.encode because it increases the size. So I need to directly convert from EncodedImage to byte array. FileConnection fc= (FileConnection)Connector.open(name); is=fc.openInputStream(); byte[] ReimgData = IOUtilities.streamToBytes(is); EncodedImage encode_image = EncodedImage.createEncodedImage(ReimgData, 0, (int)fc.fileSize()); encode_image = sizeImage(encode_image, (int)maxWidth,(int)maxHeight); JPEGEncodedImage encoder=JPEGEncodedImage.encode(encode_image.getBitmap(),50); ReimgData=encoder.getData(); is.read(ReimgData); HttpMultipartRequest( content[0], content[1], content[2], params, "image",txtfile.getText(), "image/jpeg", ReimgData );

  • How to put reminder in Blackberry calendar

    - by anta40
    I need to put several reminders in the BB calendar. The idea is several hours, or days before a promo expires, the alarm will remind it for you. Here's my code so far: long ONE_HOUR = 3600; long ONE_DAY = 24 * 3600; try { EventList eventList = (EventList)PIM.getInstance().openPIMList(PIM.EVENT_LIST, PIM.READ_WRITE); BlackBerryEvent bbEvent = (BlackBerryEvent) eventList.createEvent(); FavoritePromo promo; if (eventList.isSupportedField(BlackBerryEvent.ALARM)){ for (int x = 0; x < promos.size(); x++){ promo = (FavoritePromo) promos.elementAt(x); time = (StringUtil.strToDate(promo.getExpireDate())).getTime() - value; bbEvent.addString(BlackBerryEvent.SUMMARY, BlackBerryEvent.ATTR_NONE, promo.getTitle()); bbEvent.addDate(BlackBerryEvent.ALARM,0,time); bbEvent.commit(); } } } catch (PIMException e){ } Every time i run it, an "IllegalArgumentException" is always thrown. I'm not really sure what goes wrong here...

    - by Jessica
    I have a screen with two RadioButtonField objects. By default, the first RadioButtonField shows a rectangle around it to show its selected, and the rectangle moves if you change the selection to the other RadioButtonField or other buttons and textboxes on the page. What I would like to know is...is there a way to hide this border that shows the selection/border?

  • Blackberry - Programmatically extract/open zip file

    - by KKlucznik
    I have looked online with mixed results, but is there a way to programmatically extract a zip file on the BB? Very basic my app will display different encrypted file types, and those files are delivered in a zip file. My idea was to have the user browse to the file on their SDCard, select it, and I extract what i need as a stream from the file. is this possible?

  • Programatically add a wifi network on the BlackBerry

    - by Ridz
    Hi, As opposed to manually setting up a Wifi network(scanningaddingset encryption settings, etc) I'm trying to create an app that once the user enters his login credentials will automatically add the wifi network complete with the necessary network settings. Maybe i've been searching using the wrong keywords but I havent stumbled upon anything about this. I'm wondering which class(es) I should be looking at. Is this even allowed by the API?

  • SQL Developer Data Modeler v3.3 Early Adopter: Collaborative Design via Excel?

    - by thatjeffsmith
    As you may have heard last week, we have a new version of Oracle SQL Developer Data Modeler now available as an Early Adopter release. Version 3.3 has quite a few new features and I’ll be previewing them here. Today’s topic is our new Excel integration. It builds off of last week’s lesson: Search, so you may want to go read that first. They say it takes a village to raise a child. I say it takes a team to build a data model. You have your techie folks, your business folks, your in-betweeners, and your database geeks. Who gets to define how customers are represented and stored in your database? That data lives forever, so you better get it right from the beginning, or you’ll be living in a hacker’s paradise for years to come. Lots of good rantings, ravings, and advice on this topic in general on Karen Lopez’s (@datachick) blog. But let’s say you are the primary modeler on a project. You dutifully interview the business folks for their requirements. You sit down and start to model and think you’re pretty close. Now you need someone to confirm your assumptions and provide some feedback. Do you send your model over? Take a screenshot and blow it up on a whiteboard? Export to HTML and let them take a magic marker to their monitors? Or maybe you bite the bullet and install your modeling software on their desktops and take the hours or days required to train them up on how to use the the tool. Wouldn’t it be nice if they could just mark up their corrections in Excel and let you suck the updates back in? This is what we have started to build in Oracle SQL Developer Data Modeler. Let’s say you have a new table called ‘UT_STARTUPS.’ It looks a little something like this: A table in Oracle SQL Developer Data Modeler What I would like to do is have my team or co-worker review how I have defined those columns. Perhaps TIMESTAMP is overkill or maybe the column names themselves aren’t up to snuff. What I am going to do is now search for all the columns in my table, then export that to Excel. So do a search for UT_STARTUPS. Search, filter, then Report With the filter set to ‘Columns,’ if I do a report I’ll be only getting the columns that are resolving to my search term. So as long as my table name is unique in the model, I should get what I’m looking for. Here’s what I see when I click on the Report button: XLS or XLSX, either format is just fine I want to decide how the Column data is exported to Excel though, so I’m going to create a report template that I can use going forward. So click the ‘Manage’ button and setup a new template. I’m going to call mine ‘CollaborativeDevelopment.’ The templates allow me to define what properties are included in the reports. Once this is set, I’ll have the XLS file generated, and get to work Now let the Excel junkies do their stuff Note that not ALL of the report properties are update-able (yes, I made up a new word there) via Excel. We’ll have the full list of properties documented going forward, but in my Excel sheet, note that I can’t change the table name or the data types for the columns. I’m going to update some column names and supply ‘nice’ comments so the database users know what’s what. Here’s my input for the designer/architect/database dude: Be kind, please rew…use comments. Save the file, email it back to your modeler. Update the model from Excel That’s right, it’s a right mouse click from your model in the tree If everything goes right, you’ll see a nice confirmation message: It’s alive! Another to-do item on tap – making this dialog more informative. We’ll be showing exactly what in your model was updated from Excel. Let’s take another look at the model now Voila! Why are we doing this again? The goal is to reduce the number of round-trips from the modeler and the business process owner. One is used to working with Excel – why not allow them to mark up their changes in the tool they already know? This is an early adopter release and I anticipate this feature getting a good bit of tuning up before we release. Why don’t you download 3.3, give it a whirl, and let us know what you think?
