  I'm runing the Project One (first part) and record information to be stored, and then I WANT TO runing the project two (part two), but I received an error message telling me there are two same defined the class in the system, I try to change the class name of StoreInfo in two project, the last of error messge disappeared , instead of a CastClassException error, I am so sad...

  For a long time debugging I found some interesting things, look at the below codes to two projects, please read the name of the StoreInfor class, not StoreInfo.

   private MenuItem getItem = new MenuItem("Get", 110, 11) {
      public void run() {
        synchronized (store) {
          _data = (Vector) store.getContents();
          if (!_data.isEmpty()) {
            StoreInfor info = (StoreInfor) _data.lastElement();
          }
        }
      }
    };
  

  Now the _data class name is StoreInfo@xxxxxx (using _data.getClass () .getName ()) and class StoreInfo project two was renamed to StoreInfor, of course, I received a CastClassException error.

  I finished the story, and I need some guys to help solve this problem, tks a lot! ~

• Problem in the use of the JDE 4.7 NumericTextFilter.ALLOW_DECIMAL

  Hello

  I wrote the code for the decimal entry as

  public NumericTextFilter numFilter = new NumericTextFilter (NumericTextFilter.ALLOW_DECIMAL);

  private AutoTextEditField test = new AutoTextEditField ("","", 8, BasicEditField.NO_NEWLINE | ") Field.FIELD_HCENTER);

  test.setFilter (numFilter);

  Here's my problem while using the virtualKeyboard Strom I m not able to type '1' textpad and when I click 1 entry appears as "." (DECIMAL)

  and when I m tilt blackberry in landscape mode so I m get '1' and '. " at different place and I m able to type.

  is there some their in blackberry os. 4.7.0.75 for this their.

  can we know what is theirs.

  Respect,

  Neev

  This is a known bug in version 4.7. It is fixed in a future release - I believe in 4.7.0.86.

  The only work around is to rotate the phone to get the view of the landscape. The keyboard works properly in this view.

• AutoTextEditField context

  Hello, bb forums!

  I am new to the development of bb and on these forums.

  And currently, I am facing a problem.

  I have AutoTextEditField. And I have the class that implements FieldChangeListener.

  I call the method fieldChanged() of the receiver after a series of methods setText() .

  fieldChanged (message, 123);

  Which framework should I use?

  * now I use 123, and it works perfectly, but is there an appropriate?

  I think you will find that it is a constant definition, like FieldChangeListener.PROGRAMMATIC, if the change has been performed internally by the program, or '0' if carried out by the user.

• MacBook Pro display problem

  Hello members of the community.

  As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

  The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

  I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

  It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

  I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

  In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

  I have the entry level MacBook Pro with the retina, last generation.

  Any constructive contribution welcome!

  See you soon.

• with IOS 10.0.2 - 5s iphone Bluetooth problems

  Since upgrading ISO 10.0.2 my M50 from PLT Plantronics (helmet unique headset) do not reliably connects with my iPhone 5 more. I have to go to the settings, activate bluetooth turned off/turned on, touch the device on the bluetooth page, etc. Once it connects successfully, it will reconnect (if I turn off the headset and turn it back on) for a short period. The next day he does not connect itself but I play with bluetooth on the iPhone again.

  It has always worked perfectly before the 10th of IOS.

  And, as I noticed others mentioning, the volume is much lower with IOS 10. The maximum volume is much lower. I can barely hear it now, more normal background noise, while driving.

  I did:

  Forget this device for the PLT M50 and paired again (several times)

  I did a Reset Network Settings

  I don't know what else to do - but it's a 10.0.2 IOS issue.

  Hello AppleUser2k,

  Please ask questions about your problems of connection between your iPhone and your Plantronics headset since you upgraded to iOS 10. I understand how important it is to have your Bluetooth devices connect with your iPhone with reliability. Here's what I recommend.

  The first thing we want to make sure is that all your data is safe. You can perform a backup in iCloud or iTunes using this article: backing up your iPhone, iPad, and iPod touch.

  Once your data is safe, try the troubleshooting steps in this article to help: get help to connect a Bluetooth accessory with your iPhone, iPad or iPod touch device should also check with the manufacturer that the device has all the drivers and firmware to work with the new version of iOS.

  If you have checked everything and that you have installed the latest firmware or driver and always are problems, please be aware of your surroundings when you encounter these problems. If you can isolate the time or location, you see the problems, you can isolate the cause. You can even see this help article to ensure that you are not affected by outside interference: the potential sources of Wi-Fi and Bluetooth.

  Thanks again and have a great rest of your day.

• Problem activation ISO 10 September 2016

  After my Ipad iOS 10.0.2 update I could not activate because it says I am not access with the original Apple journal. Makes no sense. I bought the new Ipad in seven of 2013 Dabs.com. She has been linked to my Apple account 10 days ago (I deleted my profile by own Apple support Web site suggestion as a way to fix my problem, the other restoration/upgrade to the Ipad with ITunes update). I contacted the support of Apple (I have two numbers in case Apple). Asked Apple support to provide a proof of purchase I made. Told me now the reception that I provided does not correspond to my Ipad, but Apple isn't going to help with all the details to help to regularize the situation. The Ipad is mine and well was linked to my account from the date of purchase in September of 2013 until I removed it at the suggestion of site specific help from Apple. I now do not have access to my ipad £460 for more than 10 days and have lost money and time talking to 4 different cooperatives of Apple, after 6 calls and none seem able to deal with a ridiculous situation. Alexandre Vitorino (Apple) seems to have the best handle on weird how this situation is. Please can someone fix this? A software update on an Ipad that I own shouldn't stop me using it and then force me to prove that I admit actually before I use it again! I'm a professional businessman who uses it for meetings of the Council. I have a receipt for my camera and get treated like a kind of criminal.

  My sincere sympathy for those who can't find their original receipt or forget their original log-in Ipad because Apple does not help, you and your Ipad will be also useless mine is currently!

  If you are in the same situation please confirm to this post. I can't be alone, if she feels like it!

  Lock activation occurs when the ID of original Apple blocking it does not match with your current Apple ID.

  Until you can bring a receipt valid from an Apple reseller or authorized, it's nothing you can do.

  BTW, the polling stations in this Apple-owned forums is prohibited. You can review the terms of use.

  For example, you specify that the device does not display the lock screen, correct? Do you use Touch IDS? If so, try to put your finger on the device to see if it's what he wants.

  See you soon,.

  You can not. The only way is if the previous owner release form their iCloud account. If they will not do for you, it means nothing to you.

  but he remains arrested with 519 photos

  I tried to fix the bookstore. restart analysis but still stuck to 519 phoos.

  Does anyone have the same problem and a solution?

  Thank you

  How long it has been blocked? You have a very large library so I keep the Mac awake and fed and the Photos doesn't work does not and give him a few days - usually messing slows it rather than speeding it and is a 'restart Yvert"command
