• Research within the buffer to the client in the OSMF player empty the buffer to the client

  Hello

  In one skin for OSMF player I have seen that when we seek bar then load and current bar the two becomes equal to the point of pick up and he starts again seek point if loaded bar loading was first superior of the current bar.

  In other words, I can tell when we perform the search operation then bufferLength becomes 0 and start buffering once more from the point of pick up but if we are looking in the memory buffer to the client why must she do bufferLength 0 and empty the old data that has already been buffered.

  Anyone has idea about this issue.

  Kind regards

  Yes, that's correct. The event you want to play can be MediaPlayerCapabilityChangeEvent.canPlayChange.

• Problems with emptying the buffer for profile motion; Errors-70061-and-70137

  I'm trying to generate a movement code that synchronizes a motion profile with data acquisition using breakpoints; the VI (joint) is loosely based on the 25229.vi provided on ni.com.  I use a PXI-7354 controller and running Labview 2011.  I can run the VI once (successfully), complete the desired query, trigger the breakpoint and take data with no error message.  Then if I try to run the same VI immediately after, the engine will move only steps 5 and 6 and then stops. No data is collected, and no error message is displayed.  Then when I run it it a third time, movement and data acquisition complete, but I get error messages in the clear Buffer.vi saying that the buffer is used (error-70061).  I also have error-70137 to the CheckBuffer.vi, which I think is because it is still monitoring the buffer after the failure of the ClearBuffer.vi.

  Do I need to include a clearing of additional buffer somewhere initialization?

  Thank you

  Matt

  Hi MattCS,

  I think you see this undesirable behavior because you are not initializing your shift registers. Data of your last run are still saved in your shift registers so the next time you run it will start where it left off. So if you press stop during execution of the time VI the first it stops and everything works, but then the second time you run the VI the loop will stop after its first iteration since its listing, the old value of the shift register. Also if you ever get an error in the while loop will continue to be there every time that you run the VI. Please try the changes circled in the picture below and see if that helps.

• Portege M500 cannot start when the USB ports are loaded

  We have a M500 that recently seems to be affected by start-up problems when the USB ports are loaded with things like KB and Wireless Mouse USB external adapter.

  When these ports are occupied at the start, all the usual tools seem do not load and the associated icons do not appear in the toolbar at the bottom of the screen. The machine in question XP Professional and has 2 GB of RAM. The machine software is generally updated. Machine seems to start normally when the USB ports are empty.

  Once completed a successful boot USB ports can be occupied and the machine will then seem to operate normally.

  Any thoughts?

  Thank you.

  Hello!

  In your case, I would do a BIOS update and also the chipset driver.
  The two you can find on the Toshiba site. I m not sure but I think you have a model for Canada:

  Have you tested the devices USB on another computer laptop or PC? Maybe the problem is the keyboard and/or the mouse and not the laptop.

  Good bye

• How to clear the output buffer, possibly resize and burn again, before you begin the task of output

  I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

  I have an output buffer that I want to be able to (re) write to without starting the task output.

  More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

  In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

  The generation is not yet started, and not enough space is available in the buffer.

  Set a larger buffer, or start the generation before writing data more than content in the buffer.
  Property: DAQmx_Write_RelativeTo
  Value: DAQmx_Val_CurrWritePos
  Property: DAQmx_Write_Offset
  Corresponding value: 0
  Property: DAQmx_Buf_Output_BufSize
  Corresponding value: 92

  In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

  DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

  Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
  Task name: _unnamedTask<0>

  State code:-200547
  function DAQmxWriteAnalogF64

  I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

  Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

  Is it possible to "remake" the writing of output before you begin the task?

  Thank you

  Michael

  Today I have no material practical to validate, but try unreserving task before writing the new buffer:

  DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

  With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

  I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

  I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

  

  The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

  Best regards

• generate a digital triggering out CH1 (low and high) for the USB-5133

  Hello

  I would like to generate a digital triggering on the USB 5133 CH1, is this possible?  I tried with the PFI 1 successfully but the output is only 3.5 v and I need to 5V, because this trigger signal goes to a box of pulse generates a signal, which is received by the CH0 on the USB-5133. This configuration works on the 5102 OR but because of the treatment, I am obliged to try a new device.

  Channel 0 and 1 are only entries then you will not be able to use them to generate a signal.  All of our products current digitizer that are recommended for new designs use 3.3V CMOS logic levels for PFI lines in output mode.  Your best bet to generate a digital triggering 5V would be to use an external buffer that can accept 3.3V CMOS levels as an input, but is under voltage of 5V.  Here are some that might work for you, but there are many others: http://www.onsemi.com/PowerSolutions/product.do?id=M74VHC1GT126DT1G adding a buffer in line with the trigger signal will add delay, so you will need to ensure that it is acceptable for your application.

  Hope this helps,

• DAQmx error: DAQmx Every N samples transferred the event buffer is not d support channel types

  Hello

  When I move my code in my application hangs when it comes to DAQmxRegisterEveryNSamplesEvent with the following error

  DAQmx error: DAQmx Every N samples transferred the event buffer is not d support channel types

  Status code :-200980

  Any idea?

  Greetings;

  When you're talking about an alternative, do you mean a sleeve of spare or chassis or an alternative in the code?

  If it's a matter of code, then you probably need to change your software architecture to adapt the capacity of the installation. In order to avoid to use the FIFO and so have the problem you are experiencing, you avoid needing to register for this event? A few examples on different architectures is on the following link:

• How the buffering is the USB-6008/6009 has?

  How many readings can be stored internally until the unit overflows.  Pointers to info that describes this would be appreciated.

  Thank you.

  512 bytes.  256 samples.  This is specified in the USB-6008 user manual.  See Specifications, input analog, AI FIFO (page 24).

  You can also always determine this programmatically.  Create a task of the desired type and query the size of the buffer in a property DAQmx buffer node.

• Cannot eject my external drive after emptying the trash

  I have a very specific question and I was wondering if someone else he met.  This is for Windows XP.  If I delete a file from my external USB drive (happens to all readers regardless of the brand, size, etc.) and empty the trash, I can't remove the disc.  This only happens with this particular scenario
  but so far is happening on 2 PC's, I have at home.

  I checked for file handles and there is no open file handles.  I tried to wait a while but still not good.  My only solution is to shut down the PC and remove the disc.

  It would be great if I can find a solution to this problem very weird.  Thank you all.

• How to upgrade the already encrypted files on the USB HDD with new XP Recovery certificate

  I backed up the files encrypted in My Documents on a USB drive on which these files are also encrypted state. My computer crashed so I reinstalled the operating system. I wanted to send records encrypted USB HD to my computer or tried to copy projecteurDu and paste them into My Documents. I could not do this because I got "an error occurred in the application...". access privilegesDo i., access is denied. "I created a new recovery certificate and put in place a recovery agent. From there how I update the previously encrypted files on th USB HDD with the new recovery certificate? I'd appreciate a step by step procedure. Can I select the USB drive in the command line and run cipher/u on this drive or make the command/u of encryption on the computer without connecting to the USB HDD

  Sorry to say that my bet is that you never gain access to these files again.

  When you created the files encrypted, Windows creates a key for decryption to access these files and stored, encrypted in your certificate store.  When your system crashed, the decryption key has crashed with it.  Without this key, you will never have access to your encrypted files.  If you have recovered from a backup image-style, you should be able to access these files.  If you've recovered by installing Windows from the installation disc, then you have created a new and different installation with different Secure ID (SID) and a certificate store empty.  A recovery agent will only retrieve encrypted files that were created after that recovery agent was in place - as a new certificate.  What you really need to do, it's your old certificate to restore the backup that you created when you started using EFS.  The following article is mandatory for anyone using the EFS file system.  Special attention to the paragraph entitled "why you should back up your certificates.

  "Best Practices for encrypting file system"
   <>http://support.Microsoft.com/kb/223316 >

  If you do not have a return to the top of your certificate, then things look dark.  There is a program called "AEFSDR' whose 'professional' version comes through what has not been overwritten on your hard drive in search of remains of certificates that could be delivered together to recover.

  Good luck

• No room left even if I delete songs - using Mac, empty the trash

  I use my Sansa Clip to listen to audio books only. Lately even if I delete the books there is a msg saying no left when I try to add more space.  I'm emptying the trash on my Mac that I use to manage files Sansa.  Memory says 3750 used, 22Mo left, no matter how I delete! Help?

  Is that what you're emptying the trash of Mac with the connected Sansa?

  Have you always used a Mac? If you also use the Sansa with a Windows computer, then it may have been connected in MTP, which is invisible to the Mac mode. You must connect to a Windows computer and delete the files from there.

  Then go to settings system/settings/USB Mode and make MSC.

  If you just want to start over, you can go to Settings/System Settings/Format and use it. It will remove everything you put on the Sansa.

• Problem with the files not showing (after changing the USB mode)

  I have a sansa fuze 4 GB. version V02.01.09A. OS: Vista Service Pack 1. My rocket was working fine until about a week ago, when it stopped charging. but after installing the new norton 360 sansa is more appeared in my computer or Windows media player at all. I tried updating the driver but it says that the pilot was already up to date. I tried other USB ports again (front and rear), did not work. I decided to change the USB mode and it has finally started to load again in MSC mode.

  now, for the problem I currently have and, when I click on sansa via my computer and go to the music folder, it says "this folder is empty". I unplugged and watched in my music list, and all the music is there. I tried to put a new song on the player, disconnected, and when looking through the songs of the player the new song is here. I reconnected it, the new song is in the music folder, but the other songs are not listed. In addition, I have a microSD card that is listed as "o" in the car, all the songs I had on this appear, but not those on memory internal to the sansa.

  How can I get again list all music files in the folder?

  Note: I do not sync as it has only some of the songs I want on my sansa. the way I add songs is to copy and paste to the folder of the sansa player

  Okay, I don't know why or how, but it works now in MTP mode. I saw you are solutions, but I decided I'll just change the mode before trying to have ideas. until I reconnected it I also removed the microSD card, and it worked perfectly (make a backup of my songs). the problem could have the sd card in all this time?

• Windows does not recognize the USB flash drive

  Hello
  My USB does not work when I plug. It seems that Windows recognizes the device because it is found in the Solution Explorer window, but if I want to create a folder or a file on the USB key I have the following message:
  "Cannot find this article.
  It is no longer in < %3="" null :="" optext=""> . Check the location of the components and try again. " < br=""> also the files that are copied to the USB flash drive are not visible in Explorer and it looks like the drive is empty.

  I want to emphasize that the same (Kingston) USB flash drive works perfectly under Windows XP operating system on another computer so it may not be a problem with the device. The same problem also appears when you use a different USB (another manufacturer).

  Thank you!

  Hey, 101 a.

  , I just posted a fix I found for my USB flash/go to work again.  It was a very simple solution, too.

  I unplugged all USB devices first, then tried my USB jump drive again.  IT WORKED! I've narrowed the problem to the new printer that I use.  It's a Mono Dell Laser MFP 1125.  Whenever it is plugged into a USB port, my USB doesn't work.  All other devices work, but not the USB is the printer is connected

  I don't know what done to block the flash/USB key, but unplug printer allows the jump command to work again.  I will contact Dell on what did the printer driver to block the flash player.  Just an info on the fix I found.

• BitLocker without TPM refuses to recognize the USB key at startup.

  I have a Windows 7 PC, I'd need to BitLocker, but it fails to recognize the USB key at startup. I've resorted to skip verification and now enter the recovery key every time you start (this PC has a lot of data on what should be confidential), but it's not ideal.

  What is curious to me, is that the computer will start perfectly fine from a USB key, or produce a message of type "non system disk or disk error", if the USB key in question is not bootable. So it is not a matter of lack compatibility USB BIOS. When Bitlocker should read, yet there is no actifvity on the USB key. It seems to just try to read the empty floppy drive then give up.

  The PC is an all-in-one RM with an Intel D915GX motherboard.

  I tried two different USB, 64 megabytes cheapo player drives I usually use as a Bitlocker key and a 2 GB Cruzer Blade. I mucked with some of the BIOS settings but not in a particularly organized way. And I checked the key file is saved on the disk. Everything I did, Bitlocker will not always see the USB.

  Any suggestions?
