• How to detect the device profile

  Hello

  I want to know if its possible to know the current profile of the BlackBerry device. I want to know if the device profile is set to vibrate. Is it possible (API) that can be used if the device profile is vibrate or strong?

  Is it possible to play the sound in my application when the device profile is silent?

  P.S. It actually makes a lot of sense that there is no way to know the current profile as a single number or a text string. That's because a notification profile can be customized very detailed by the user (on the base by source) and so it is technically impossible to summarize all these customizations in a single number. In addition, profiles can be cloned and copied, turning the profile index in a not so useful concept.

  I guess that the isVibrateOnly and getMasterNotificationVolume methods are a first step in a middle ground between too little and too much detail detail. These two parameters describe the current profile using a small set of useful applications user-model-relevant parameters to decide what to do. Ultimately, most users really care only if there is strong sound notifications issued or not, if virbrate notifications are enabled and if the LED notifications is enabled.

• Boot failure when you attempt to auto detect the USB mass storage devices

  I have two USB mass storage devices.  The sizes are 320 GB and a to.  I had problems at the start to automatically detect a storage device.  After reaching the Office I can usually unplugg the 320 device, reconnect, Windows detects the device.

  August 10, I bought an an external HDD TB to start the backup of my entire C: drive operations.  I rebooted automatically while watching a DVD tonight.  I rebooted the PC and hanged when executing start-up procedure notice of automatic detection procedures.  I held the Start button to shut off the PC. I unplugged the external hard drive, PC rebooted. Start continued without external devices.  I reconnected it the external hard drive upon arriving at the office.

  The purchase of an external hard drive, see the same issue using the smallest disk, tells me that the error is in the operating system.

  Hi Troy382438,

  1. is this startup crashes before windows loads?

  2. you have SP2 installed on your computer?

  If windows hangs at the POST (Power-on-self-test), you may need to update the drivers from the motherboard.

  If windows crashes after windows loads, you can try the following steps.

  Step 1

  Install SP2 if it is not installed.

  Step 2

  Run a SFC (System File Checker) scan.

• MacBook detects the iPhone but doesn't detect photos on the iPhone.

  When I plug my iPhone into my MacBook, Photos detects the device name and the box I choose "Open of Photos for this device." However, none of the photos on the device appear in the main window, not even pictures/videos that have not yet synchronized to iCloud. Why is this happening?

  I'd love to be able to import from and delete the photos on my iPhone using Photos to the MacBook when iPhone is connected, is it possible?

  I iCloud running on the iPhone and MacBook, but this way of synchronization is not consistent - for example most of the photos on my iPhone for August is not synchronized to iCloud, despite pictures before and after, then after having downloaded and is available on my MacBook. Why is this and how do I solve this problem?

  Connect your phone and whie it is connected do a soft on restart

• How can I detect the support version lower than 4.7 touchscreen

  Hi all

  I am developing an app for non touch devices with version 4.5 of departure and now will make the same application for devices supporting contact, so planned to use the Touchscreen.isSupported () - but it is available only from 4.7. But the app should take charge of 4.5, so how do I detect the device is palpable or not palpable in version 4.5?

  Thanks in advance,

  Kitty.

  You can use this code:

  new Canvas() {}
  protected void paint (Graphics graphics) {}
  }
  }. hasPointerEvents()

• Intercept touch green application event when the device is locked

  Hi, I'm new to blackberry. What I want is I want to take a key event (green or red button) when the device is locked and do specific tasks in my application that runs in the background if this button is pressed. Is this possible? How can I do?

  Just to be 100% accurate, it is possible for a keyListener (look to the top of the class) to pick up some events even when running in the background.  It can be different events when the device is locked.  Indeed, the events may be different depending on whether the "locked" screen is currently displayed or not. And the entire lot is dependent on operating system level, in other words, the same device running two different levels of OS will possess differently in terms of what keys can detect a listener in the background.

  So if you have a BONE and a specific device, so it might be something you can do, especially if it is an older operating system.  However if you try to create something that works generically, then know that I've tried and failed!.

  The qosmio g 50 (windows vista ultimate) detects more devices via bluetooth
  Until two days ago, I pointed out quietly via bluetooth mouse. And then, do not know what is success does not detect any more.

  I did a test to see if it could depend on the PC or the mouse.

  I took the phone with bluetooth, I turned and qosmio, is not detect the phone.
  And the phone does not detect the qosmio via bluetooth.

  What checks can I make on the qosmio while ' I detect devices via bluetooth?

  Tank you

  Have you used the FN + F8 key secret to switch on the BlueTooth?

  Please check if the FN key works correctly, otherwise, go to the button start-> all programs-> Toshiba-> Flash Cards Support utility and restart the software.

• USB-6525 NiDaqmx how to detect where the device interrupts the communication

  This could be considered a more generic question for NiDaqmx, but I write a custom control for internal use with the USB-6525 and possibly other devices of i/o using c#.  I use DigitalChangeDetectionEvent to warn me when an entry has changed and everything seems to work very well.  In an effort to be complete, I decided to unplug the USB cable and see the result and found that no error has been detected until I tried a writing output.  This is not acceptable because under normal conditions abstraction entry begins a process that will change output - given that admission never happens, the system is basically hung.

  I tried many things and have spent more time on what I want to admit so I would like to hear suggestions on how to address this problem.  Here are my attempts that I am not satisfied:

  (1) periodically switch (pulse) output that allows to detect the problem, but I may not be an available exit, so this isn't a good situation.

  (2) periodically trying to read the input byte with the same entry workflow, this does not work because I believe that the other player is still active with the DigitalChangeDetectionEvent.

  (3) attempted to take the message of Windows to change hardware, but seems too complex.

  (4) I read on the guard dog, but not sure that it is available on the box USB-6525.  So before I start with this I'd hear rather suggestions of others with more experience.

  Any suggestions please?

  THX, Ed

  Hi IntegroEd,

  Those are all very innovative way to potentially address the problem, and I'm sorry you haven't seen success with them.  Fortunately, the typical way to capture a break between a device of data acquisition and monitoring system is indeed a timer, and the 6525 has the innate ability to use the feature, as seen on page 5 of the user manual.  I suggest you go that route, if another user does not post a peripheral solution specific to your case.  This is a documentation on the implementation of the monitoring-

• Comm port not detected by VISA / MAX after the device power cycle connected

  I have a device communicating via USB virtual comm port. The device and labview program both work very well, most of the time. The program is designed for the automatic connection for the connected equipment. It works perfectly when I unplug and reconnect the USB cable.

  However, if the unit power cycled as the USB cable is connected and the program/vi is running of things go wrong. The device enters a phase of boot loader for a few seconds to the power upward, if labview tries to query the port comm during this phase the comm port is corrupted in some way and is no longer recognized by VISA / NI MAX. However, other programs, hyperterminal, etc device manager can see and communicate with the port when the boot loader is complete. For Labview / NI MAX to see the port I have to physically disconnect the USB cable. The program does not need to be restarted in order to detect the port comm again and, infact, labview is restarted or my compiled program does not solve the problem. Physically disconnect the USB port allows visa / MAX OR see the port is connected.

  It seems to me that there is a problem with VISA where somehow if a device is not correctly identified by VISA during the first attempt it just does not take into account the port until a physical intervention. Is there a way to force VISA to reassess completely all connected comm ports?

  Hello MJanus,

  As far as I know, most of the virtual com ports are not fully supported by VISA so some quirks in its operation are to be expected: http://digital.ni.com/public.nsf/allkb/6E1922B526572CB8862571AA00544057?OpenDocument

  Officially, we do not support the use of com virtual ports, if unfortunately, the feature you have now is probably as good you'll be able to get with this configuration. I know it's not the answer you were hoping to hear and I apologize for the inconvenience, but it is not really possible visa work well with all software virtual com port due to the wide variety of products available.

  Kind regards

• Bluetooth randomly, and now the device is not detected

  Hello

  I bought a laptop 15-J108la want a month ago (8.1 Windows 64). I also bought a Microsoft bluetooth mouse to use with it.

  I first noticed mouse stoped working randomly, maybe 2 times a day. Sometimes it was enough to turn off and on again to get it back, but sometimes I had to reboot.

  I updated the driver bluetooth (Bluetooth 4.0 Driver Intel, 2014-01-18, Version 3.1), the problem persisted, but seemed less frequent.

  After you install an update for the wireless network card device manager today announced that Intel Bluetooth 4.0 device has been failing. Try to dissable and reactivate, but the device has simply disappeared. Now the Device Manager indicates an "unknown USB device" with error 43, and Bluetooth devices are not detected, no matter how many times I reboot.

  Any help will be much appreciated.

  Using the generic drivers provided with windows 8.1 instead of Intel drivers, finally solved the problem.

  No more intermittent, peripheral stranger either.

  I was foolish enough to install the latest driver updated to Intel to see if it has addressed the problem, but it was as bad as before. I had to go back to the generic drivers, once again and voila: everything works like a charm again.

  I hope this helps others.

  And Intel: come on, you should do better!
