• any API to check if the device memory is encryption enabled or not

  Hi, expert,

  as we know, the blackberry phone, user could activate the encryption of memory of the device and media card encryption. We wonder if there is no API to query whether the encryption is activated or not. I did some research on the internet and I have found no related answer on that. Just wonder if it is not for this as the test of playing a particular file.

  Thanks in advance for your understanding on this.

  Thank you, with your suggestion, I discovered that I could know if device encryption is enabled by creating a new file on the disk (for both memory and the sd card). If the file was created is successful, check the file extension, it should have .rem extension if encryption is enabled. If file creation fails if the phone is locked (not always at default), if the error message would be the specific error message, it would mean that the encryption is enabled as well. However, if it is an another error message, it is determined here. We will have to wait to make sure that the creation of files could manage to check.

  Check in the Device Manager to see if the device re-installed. If it isn't action - Scan for
  hardware changes.

  Also check the BIOS - Setup/settings - often F2 for system start - make sure that the USB port
  is activated. Check with Support from the manufacturer of the system/motherboard, their documentation online.
  and ask in their forums.

• How to check if can device is busy to write or read

  Hi, I'm using NI USB 8472 low speed CAN and I want to check if the device is used.

  because if I send a frame to the device CAN I have a continuous loop, sending another frame and I want to know who I'm not write or read my continuous loop at the same time.

  This loop is made with an asynctimer.

  How can I check if the device is used to prevent writing or reading at the same time?

  Kind regards

  If you choose to use the CVI locking mechanism or the methods of the critical Section of the SDK, the net effect is exactly: a single function that is used by all parts of your program to access a resource atomically. You needn't semaphores here. For example:

  Critical_section cs;         Declare in a scope that includes all threads wanting to use the resource

  void Init (void) {}

  ...

  InitialiseCriticalSection (&cs);)    Do this somewhere soon, before you actually use

  ...

  }

  void CommFunc (...) {/ / This function represents the resource that are not accessible at the same time}

  EnterCriticalSection (&cs);) Stop another thread to run past here

  ... / / Now this block of code can run without fear to be readmitted

  LeaveCriticalSection (&cs);) Finished - let other threads are using the same code

  }

  My main programming in real time, I tend to use the components of the SDK, as described above. Roberto promotes the CVI ones - I think that in this case, their operation is identical.
