CD rom only reads or writes data

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• Read or write data in excel

  Hello

  I wanted to know if it is possible to read or write data in excel programmatically? And if possible how to do this?

  I searched a lot on this subject. All forums say how Sung some software. What I wanted to do is, I want to create an application in which I might be able to write data to excel and also read data from excel. Specifically, I can do Java using some jxl. Is there something similar to that?

  Please help me on this since it is a very urgent need for my client.

  Thanks in advance.

  There is no API to write files to Excel on the BB, and I think you will find that this jxl use J2SE functionality that is not supported on the BB, it will be difficult for this port.

  If you plan to be able to put an Excel worksheet on the SD card on the BlackBerry and directly using these data, there still, sorry this is not supported.

  I would investigate export Excel data to SQL and then using SQL on the BlackBerry.

• CD-ROM/DVD-rom cannot read CD - Rs (data or software)

  Windows XP SP3

  32 bit

  Antivirus: Optus (australian) Security

  No anti-spyware and any third-party firewall

  CD/DVD-Rom: 20 x LG GSA-H55N

  Since this CD-ROM/DVD-rom + 3 years now and used to burn/read CD - r.  Since last year, he was not able to read or burn to CD - r (data, audio, old games, software installation CD).  Burning & playback on DVD - r work (with a few issues).  On a previous thread, Chaos_Edit suggested to find the CD-ROM/DVD-rom by Control Panel/Device Manager - DVD/CD-ROM-rom and perform a restart on it.  Unfortunately, there was no Device Manager on my account control panel and can't find the file on my computer.    Any positive HELP is gladly appreciated.  Thank you

  First of all, download your correct terminology.  DVD-ROM (or CD-ROM) is the types of compact discs for read-only.  What you have is a 'internal 20 X Super multi DVD Writer'.

  DVD/CD burners use lasers for CD and DVD.  It is not rare to fail in front of the other.  Otherwise said, simply because your device can read and write DVDs does not mean that it always can read and write CD.

  I have no idea what means "do a reboot on" a CD/DVD burner, whether or not you use the Device Manager.  However, for later use, you can get to the Device Manager at least one of the following ways:

  • Right-click "My computer" and select Properties; Click on the "Hardware" tab Click the 'Device Manager '.
  • Press the 'Windows' key and the 'Pause' key at the same time; Click on the "Hardware" tab Click the 'Device Manager' button (of course only works for keyboards with a "Windows" key)
  • Start > Control Panel > system [or, if you use the 'Category' of the control panel view, "Performance and Maintenance" and then "System"]; Click on the "Hardware" tab Click on "Device Manager".

  I don't know where you buy hardware in ounces, but in general, a replacement CD/DVD burner doesn't have to be expensive.  In the United States, for example,that NewEgg resembles a replacement close enough to what you have for US$ 22.  Be aware that your current device uses an IDE interface rather than the more recent (and now more common) SATA interface.

• Read and write data to the content repository.

  Hi all
  We use the content repository to store a document and images on the web server in the Center.
  So we have created/setup a repository of content on the web center.
  Please proivde me some might document page to get an idea of how I can read and write the date
  content repository.
  You are most welocme to provide some idea /suggestion.
  Thank you
  Arun.

  You are using webcenter spaces or you create a custom application webcenter?

  When you create a custom application webcenter, you can make use of the workflow Documents. Jdeveloper resources catalog, you will find a few flows of Documents job that will allow you to add some components to manage documents in a folder structure.
  You must first create a connection to your content from your application server. This can be done in the Application resources, right-click on the connection and in the context menu, select "content repository". Them you must filll in connection to your content server details. Make sure you have selected "Set as primary connection for document service" because otherwise the document taskflows you deposit on your page will not find a connection.

  Once you have added the connection, you will also find a datacontrol to the content repository. In this way, you can use the datacontrol place the taskflow and you can create several custom tables.
  I'm not sure but I think the datacontrol also include surgery to create the document but I'm not sure...

  And if not enough, you can always do use the webservices provided by content server. In Jdeveloper you can easily create a datacontrol from Web services by providing the wsdl file. UCM provides for services so that you can import the wsdl into your application and you can easily create your own forms checkin, tables...

  Here is some information on how to integrate services document:

• CD-ROM/DVD-rom only reads cd - dell hybrid

  I won a hybrid of Dell, a little over 4 years ago (by Dell). It came with Vista. A year later, I put Win7 32 bit on it, Dell said that they would not support if I did. It worked great and still does... except for the dvd rom. He is not dead with Win 7 tho. He died less than a year ago. It reads and burns CD fine, but it won't read or burn DVDs.

  I can't use my dvd drivers again because he will not read it. Of course I have more support or warranty on this thing. I was wondering if there is a way to get the drivers to see if I can get it running.

  Today, I was going to reinstall the whole system but remembered my DVD rom is not reading and everything is on dvd (if it was on cd, that I could do!

  I'll probably have to go buy an external dvd rom/writer this week, but thought I'd see if there was anything I can try before doing this.

  If the drive reads CD but not DVD, it's a hardware problem. There is no driver will fix a hardware problem.

• Satellite P500/01R reads the data, but cannot write data on CD files

  I recently bought a laptop Satellite P500/01R. I am able to read a data CD, but can't write data on CD files. The CD is read/write.

  Any ideas?

  Hello

  Have you tried different burning software?
  I m using Nero and in my opinion one of the apps better combustion.
  Here, I can choose between CD, DVD, DL or Blueray (only possible if the CD/DVD drive also supports this).

  Have you also checked diffΘrents CDs from different manufacturers?
  You should do this since not all disks are 100% compatible.
  I had several problems with different CD or DVD in most of the cases it was a compatibility issue, I tried TDK and this kind of drive is compatible with my CD/DVD drive
  I m using the standard of R.

• DVD/CD RW do not read audio CDs or data or save a blank CD, but that it's ok to read and write DVDs

  My DVD/CD RW drive will not respond to CDs of any type, void, audio or data.  It whirs for a few seconds and then more nothing.  No AutoPlay (even if she is selected and in the registry as a value of 1), and if I try to click on the drive, the old hourglass stand forever and if I click on new does not, unless I have the disc, it erases then back to normal.

  The drive works fine for DVD reading and writing.  I tried to little nearly every thread relating to problems of CD, and I ran out of hair out! I uninstalled it, unplugged, repluged, rebooted, reinstalled, you name it! PC has updated the driver when I try to update.  I did all the advice regedit I saw and still nothing!  Anyone?  Please?

  Hello

  You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
  Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
  correctly.

  A CD/DVD cleaner might help.

  CD have a tolerance + - and your can read/write on the edge outside these discs
  tolerances. They may be delivered, but it is generally more economical to replace the disk.

  ===========================================

  This troubleshooting could not help if there is alignment and/or wear issues however it
  a shot.

  Step 1: Please do all the same underneath if you did some before as is often total
  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
  below.
  
  Then, work your way through these - don't forget the drive might be bad, could be a coward
  cable or slight corrosion on the contacts (usually for a laptop) and other issues.

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
  ends. Remove and replace, do not just tight. For laptops, you can often clean power and

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

  Check with your Maker system and a device for the two possible firmware updates and

  Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive

• HP DVD Writer does not read or write DVD, but only the CD

  My HP DVD 1135t burner does not read or write DVD but only the CD. What is the problem? Please help me.

  CD/DVD players use different lasers for reading/writing DVD from the CD.  All indications would point to your laser DVD as having failed.  You could try to remove your drive and install it in another computer to see if the problem follows your player or your computer, but my bet is that the drive must be replaced.

• Qosmio E10: The drive only reads DVD-R double layer / DVD + R

  Hey all,.
  I was wondering if someone could forward that request to the person responsible slimdrive firwmares to Toshiba.
  He finds that the carpet * a UJ-830 s drive not reading DUAL LAYER DVD-R / DVD + R (although it reads DVD-ROM OK DVD9).
  This disc, Mat * a UJ - 830 s equips the Qosmio E10.
  I have searched everywhere for a firmware update without success, so Toshiba are my only remaining chance.

  There is an update of the firwmare in of the Qosmio E10 driver section but that's UJ - 831S (and it does not work on UJ-830 s) :/
  Thanks for reading.

  Hello

  AFAIK this unit has a DVD Super Multi drive and it must use media suite:
  CD-ROM (Read) CD - R(read/write) CD - RW(read/write) DVD-ROM (read)
  DVD-R(Read/Write) DVD - RW(read/write) DVD + DVD + R(read/write) RW(read/write) DVD - RAM(read/write)

  In addition, these speeds are available:
  Maximum speed CD-ROM(24x:read) CD-R(24x:write) CD-RW(10x:write) DVD-ROM(8x:read)
  DVD-R(8x:Write) DVD - RW(4x:write) DVD + DVD + R(8x:write) RW(4x:write) DVD - RAM(3x:write)

  Maybe this drive can t use the double layer? I think he uses a normal DVD

  Good bye

• Qosmio X 500 does not write data to any CD

  I have a Qosmio X 500 with windows 7 (64-bit) home about this, my CD-Rom used to work fine, now it reads and serious DVD and blue-ray, but it will not read or burn CDs.

  I have no more or less than the registry filter.
  How can I solve this problem?

  Hello

  Have you tried different CDs from different manufacturers?
  Try the CD R TDK.
  I use this kind of CD and never had any problems, but had problems to write data to the other CD.

  In addition, you can try to clean the laser lens you can use a piece of hydrophilic cotton and a very small little alcohol which should be good enough.

  By the way: fire what app do you use? In my opinion Nero is great software, one of the best software in this segment.
