• How to store/retrieve 'Date' using persistent data?

  Hello everyone - this is my first post on the BlackBerry Support Forums. I'm trying to provide a lot of relevant information as possible, but if I miss anytihng or I did not understand by asking what I want, please let me know.

  Background:

  I use Eclipse IDE ver 3.5.0 and BlackBerry Java plug-in for Eclipse 1.1. I build my application for BlackBerry JRE 5.0.0.

  Question:

  I want to save a "Date" field for persistent data so that I can recover and display in the format of Date once again (no chain). Here's a more detailed explanation.

  My application has three fields on the main screen. They are

  'Name' - AutoTextEditField

  "Gender" - ObjectChoiceField

  "Date of birth" - DateField

  Using persistent data to store the data entered into these fields, as described in the BlackBerry tutorials (http://na.blackberry.com/developers/resources/A13_Storing_Persistent_Data_V2.pdf), I am able to save and retrieve all of these areas, but only in 'Chain' format.

  Unfortunately, this won't work for me for the following reason.

  I create the Date of birth as follows

  "dateOfBirthField = new DateField (" BirthDate: ", System.currentTimeMillis (), DateField.DATE" ");"

  This creates an interface evolved for Date of birth, where the user can select and edit fields month, Date and year separately. When the user saves the information entered and wants to retirve it again, I want to display the date recorded in the same format so that the user can change again in exactly the same way as described above. But if I save it as a string, I can't fill in the field "Date" with the "chain" recovered. That is, I can't do something like

  dateOfBirthField.setDate (info.getElement (StoreInfo.DOB));

  Where "info.getElement (StoreInfo.DOB)" is similar to what is described in the tutorial.

  I searched the web for a possible solution, but never found any. All I found to date stored as a string and recovered just to see what was saved, but not for the changes resulting.

  Someone please let me know if what I am asking is possible. If Yes, can you please suggest a way to do it?

  Thanks in advance.

  Or it can store any object extra Long, no need to create garbage in chains.

  Long I = new Long (1234556);

  long x = i.longValue)

• Can be persistent data that is stored on PC edition

  Working on the same project and managed to save persistent data. It's fine for the restoration of the database, but I hope to be able to change the data and possibly add more data, then restore it on the device.

  Q1: I use the right method to do this?

  I followed the example in chapert 9 of the development environment Java BlackBerry version 4.1.0.

  Q2: I came across a problem.backing to the top my persistent data is only the Setup program for one of my stores. How can I configure my backup so that the two stores are backed up?

  Thank you.

  [can someone who understands why we need of Html messages and text not just explain to me why the 'tab' and BACKSPACE navigates]

  you to another page, and not only in the icongraphic world?? ]

  At a minimum, you must understand the hierararchies and is that a cast - you can try to search on the term of classcastexception

  confined to sun.com as a good starting point (they have java tutorials large and your question relates to java).

  Anyway, after navigation back here and hoping the r eidot returns after each keystroke, let me see what is on my Clipboard.

  If you take your unknown x and do something like that.

  String nm = x.getClass () .getName ();

  the name should give you an idea what you have - in all the liklihood, it isn't what you expect, but in all cases, you should

  be able to determine if (x instanceof test) is true or false.

  Situations where you cannot know a priori what you (isn't usually a good thing), you can call different trees to help

  castexceptions (although it would probably be better of instanceof tests or same string on the result of above, nm)

  almost never, you want to implement logic nothing exceptional in exception handlers, but it can be easy sometimes).

  catch SomeDumException f)
  {mi.add (new PhluBroMenuItem (app, "without string result", idx)) ;}}

• Persistent data and uninstall an app problem.

  Hello

  I'm checking the storage of persistent data with a very silly application, but maybe I'm do sth wrong as that it does not work as I supposed it should.

  My application only checks if there is some content in the store persistent and if not, it creates. I want to check that when the application is uninstalled, these persistent info will be deleted, but as I just test, it is not.

  This is my code:

   public TestP(){
          String info = "nothing";
          synchronized(store) {
              String currentinfo = (String)store.getContents();
              if(currentinfo == null) {
                  //we create it
                  String contents = "something";
                  store.setContents(contents);
                  store.commit();
              } else {
                  //we retrieve it
                  info = currentinfo;
              }
          }
  
          MainScreen ms = new MainScreen();
          ms.add(new LabelField("Testing Persistance..."));
          ms.add(new LabelField(info));
          ms.add(new LabelField("That's all..."));
  
          pushScreen(ms);
      }
  

  And that's how I create the store

  'com.app.test.TestP' at long---> 0xcdbcc77c2e7ecf8cL
  Bank private static PersistentObject = PersistentStore.getPersistentObject (0xcdbcc77c2e7ecf8cL);

  The first time I run my application, the display will return to "nothing" and the text next time 'something '. It's ok, but when I uninstall my application, the first time also shows 'something', which according to me, that he should not be allowed.

  I do something wrong?

  How persistent store information can be removed on an uninstall of the application?

  Concerning

  Your persistent data are of type String, which is a common object of the rim.  It is not necessary for the BB to delete your data - another application can use it.

  However, if you used one of your own classes - even if it comes extends the string and does nothing else - then it will be deleted when your Application is removed, because with your driveway application, there's nothing on the device which includes that Object.

• Problem of persistent data object

  Dear Sir.

  Hello

  I am writing a module that implements the earpiece of the phone, simply

  and I would use persistent object to store information

  But I am facing the following problems:

  When I use the persistent objects, the Simulator to show that there is no instance of the application,

  as my program doesn't include any GUI,

  would my recognized program just as a Moudle and the persistent object should point the data store with an application?

  Thank you very much

• Force the persistent data that is not retained on App upgrade

  Hello

  I'm developing a new version of an existing application. The earlier version of the data stored in the persistent store of the device. When a user installs the new version of the application, they get a prompt saying something like "the persistent data is stored on the device. You want to keep these data? ».

  If the user answers Yes, the application will continue to use the old data which has been made persistent by the initial version of the application. This isn't what I need to happen.

  If the user answers no, the app will wipe the old dat and rebuild the store persistent with my current data. It is the course of action I want to request each time.

  Since there is no way to guarantee that each user will select 'NO' to this prompt, is it possible to configure the new version so that the data is not retained automatically?

  What other options are there for dealing with this situation?

  Thank you

  The f

  If the application can access the old data, why not just remove them when the application runs? In order to distinguish, again, you can design new data to contain a signature value that is not present in the old data. (For example, you can set your local record store to have record 1 always contain version store data, in a format that is not likely to be present in earlier formats.)

  An upgrade does not (usually) follow the same procedure with regard to the persistent data as a sequence of uninstall/install. However, there are occasional messages here on updates apparently lose persisted data that was supposed to be preserved. I did not understand everything exactly what are the causes which, but it has not considered the norm.

  P.S. If you use RecordStore instead of Persistable, custom classes are not relevant. The record store is deleted when all the MIDlets in the MIDlet suite, who created the store folder is uninstalled.

• ClassCastException JVM error 104 on A14 storing downloaded persisted data example

  Hello world

  I've been running examples of demonstration programs using Eclipse. I'm ok with A10 write your first application and UI A11, but on trying to run A13 storing persistent data, I get FMV 104 Eception ClassCastException error.

  The code is exaclty as in the downloaded example, so I can't imagine what the problem is.

  Someone else had a similar problem please.

  Thanks a lot for your help

  I have actually used this particular article, but I didn't need to compile. Once I realized the syntax is relatively simple, in my humble opinion.

  Good luck with the rest of your development,

  If anyone knows what I m hurt you showme how please!

  Two thoughts:

  1. If you have changed somehow the object type that you want to keep, you must remove the Simulator files before running again.
  2. How about you provide a clue as to where the class cast exception that happens? You are more likely to help in this way.

• Creating folders in the view of data with powercli store

  Hello

  We try to automate some parts of a build script and we want to create a folder in the view of data warehouses to move all the local disk.  the only place that I can create a folder has been the point of view of Cluster, DataCenter and VM.  is there a way to do this?

  Thank you

  This is a hidden folder named "datastore".

  You can do

  $dsHome = Get-Folder -Name datastoreNew-Folder -Name MyFolder -Location $dsHome
  

  Note that there is 1 folder "data store" by the data center.

  If you have more than 1 data center in your vCenter, you need to indicate what you want "datastore" folder from the data center.

  $dc = Get-Datacenter -Name DC$dsHome = Get-Folder -Name datastore -Location $dcNew-Folder -Name MyFolder -Location $dsHome
  

• Persistent data in the copy/paste

  I have what I think it's a very simple problem I had a bit of difficulty to solve. I have a few persistent data added to kFrameListBoss that is not survive a copy and paste. Paste a picture containing my in a new document entitled results in the new framework with default values. I looked at the example of BasicPersistInterface and read by all relevant parts of the documentation for the SDK, I could find, but I don't see anything that indicates a special action that must be taken to ensure that data are copy/paste correctly.

  What might be missing?

  I doubt that kFrameListBoss.

  You can add persistent data on kDrawablePageItemBoss?

  I think that kFrameListBoss is recreated by the dough.
