  Experts or those who have recovered from the same problem. Please help me.

  Thanks in advance.

  Hello

  Maybe your CD/DVD drive becomes faulty... What do you think?

  But before you think to a new disk, you must remove the server - and lowerfilters in the registry. You can follow the workaround from Microsoft:
  http://support.Microsoft.com/kb/314060

  Also, make sure that the CD/DVD drive lens is clean. You can use a microfibre cloth to clean. This rag doesn't scratch the lens.
  Check this box!

  Finally and above all, there is no special driver for CD/DVD drive. It s a part of t Windows and can be updated.

• Read and write the empty file - InputStream

  Hi all

  I have a problem with the playback of a file.

  This is my code:

  I create my file and put my datas:

  try {
          String filePath = "file:///store/home/user/locations.txt";
      FileConnection filecon =(FileConnection)Connector.open(filePath,Connector. READ_WRITE);
  
      // Always check whether the file or directory exists.
      // Create the file if it doesn't exist.
      if(!filecon.exists()) {
          filecon.create();
      }
  
      OutputStream out = filecon.openOutputStream();
  
      out.write(data.getBytes());
  
      filecon.close();
  
  } catch(IOException ioe) {
  
      Dialog.alert(ioe + "");
  
  }
  

  Then I want to read my data but my inputStream is empty and I don't understand why...

  String filePath = "file:///store/home/user/locations.txt";

  Welcome to the forum.

  Can't see anything obviously wrong.

  I suggest for now you change to use the SD card instead of the store and run in the Simulator with the SD card simulated as a directory.  You can browse the Windows directory and if, in fact, the file is created as expected.

• A reading from an arbitrary point in the buffer

  With the help of the DAQmx API, is there a way to read part of the buffer from some indexes (non-zero) to aribitrary?  I would like to combine this technique with the recall of DAQmxRegisterEveryNSamplesEvent, so that I can post a video screen to the GUI of what the system during a long acquisition.

  There are two properties in DAQmx can be useful for you: the Offset and the RelativeTo property.  Changes in parameters offset in memory where read buffer begins, and the RelativeTo parameter determines what is this offset with respect to (for example the first sample or the most recent sample).

  Int32 __CFUNC DAQmxSetReadRelativeTo (TaskHandle taskHandle, data int32);

• Problem reading the buffer full

  I made a simple VI and it works pretty well. The only problem is that when I give it some commands that I can't read all of the buffer. The best example is based on the command 'instr name' the answer is supposed to be "instr name / SO2 Analyzer / monitor SO2" (with the / a new line). However, when I press the button the command execute, I get only the first part of the answer, and then when I press once again I get the second part, and so on. Is it possible to ensure that the whole of the buffer is read?

  Any help is greatly appreciated

  Look for VISA help configure a Serial Port. See the entries called "Termination character allow" and "chariot of termination? When set to true, the option enable playback VISA expires as soon as the tank of the term (default is 0xA or LF character). You will need set the option activate to forgery and just the VISA to the Serial Port bytes.

• 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:

• Write the Image on Socket

  Hello
  I am trying to send and receive images on a socket. I know that I could send as normal files, but all the examples I found on the internet save images locally. I don't want to save the images, I want to just use them as background to a JPanel (when I get a new, it replaces the as the background). So I wrote the following code:
  Server-side:
  for (int i = 0; i < files.length; i ++) {}
  BufferedImage image = ImageIO.read (files);
  ImageIO.write (image, "jpg", os); OS - the OutputStream
  }
  
  Client side:
  {}
  If (is.available () > 0) {//is-l'InputStream
  BufferedImage image = ImageIO.read (is);
  Border PaintedBorder = new PaintedBorder (image);
  panel.setBorder (border);
  Panel.repaint (); the last 3 lines define the background image, I tested it and it works, there is no problem here
  }
  } while (true);
  But it reads as the first image, and after that the client reads images null and the server usually stops the sending of the second image. Could you tell what I did wrong? I don't know, if the client and server sync somehow?
  Thank you.

  You should definitely use a buffer around the input jack on the client side.

  On the server, you can not assume that fis.read () fills up the buffer. You need to write a loop:

  int count;
  while ((count = in.read(buffer)) > 0)
    out.write(buffer, 0, count);

  Thank you!

  Ok. So, let's think about how to add that.

  You've read online from the source file. You will need to extract one or more columns of this buffer (I'll assume that ID is a primary key, so you only need to extract the key)
  Then, you will need run a query on the ORG table with this extracted key, i.e.

  SELECT id || ', ' || value || ',' || chem
    INTO w_buffer
    FROM org
   WHERE id = <>
  

  And then, you will write the buffer to the file as usual.

  If you were to lets you read data from external tables, you can eliminate all UTL_FILE calls to read data and just attach the source to the ORG table file, i.e.

  <>
  FOR x IN (SELECT o.id, o.value, o.chem
              FROM org o,
                   source_file s
             WHERE o.id = s.id)
  LOOP
    <>
  END LOOP;
  <>

• read and write performance vm information top 10

  Hello

  I wonder if it is possible to have some information about reading and write the totals of the IOPS / s and latency? The only one i have now in Explorer 'storage '. "VM performance top 10" is average information and tip of the Ops / s and latencies. I need information of reading and writing of the virtual machines instead of the totals.

  Thanks in advance.

  GER.

  EDIT: I noticed that the discussion is started in the wrong forum. I use VoP server explore FREE

  Hello

  Unfortunately, the free tool there is no distinction between read and write IOPS / s or latency.  They are grouped in a single total.

• Size of the buffer of size/write DAQmx

  What is the strategy privileged in regards to writing data in the buffer output for a digital output or analog DAQmx?

  I ask this because in the old days pre-DAQmx, you were supposed to flow of data in the buffer in buffer half lengths, so you would write buffer_len samples on the first entry, begin the proofreading work then write half puts in memory buffer on subsequent writing, the idea being that you write half a buffer while the output card has been reading of the other half.

  It doesn't seem to be something to indicate this technique is even longer when you use DAQmx, but he still linger of links that mention the teqchnique.

  What is the way NOR recommended, and if it has changed, why?

  Thank you

  Hi ToeCutter,

  Currently there is no need to think about buffers at a level very down the DAQmx digital to analog output.

  DAQmx handles it for you as soon as you call the function "Write DAQmx".

  

  You can provide data to write DAQmx in a variety of forms (from waveforms and ending with the raw data).

  It may be different depending on the application.

  Please take a look in the manual of DAQmx writing VI:

  http://zone.NI.com/reference/en-XX/help/370469AA-01/lvdaqmx/mxwrite/

• 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 into the buffer variable published network shared

  

  I use a shared variable that is published in the network buffer to write data to an RT target and read data buffered by the host application.

  I followed a different behavior regarding data buffering using Variable vs reading read the shared Variable node.

  There is no problem the shared variable node read but using the results of reading variable function of loss of data, such as access without alkaline reserve. I can read only some of my data values.

  I see no difference in access in the buffer in LV2009 help.

  against

  Any help is appreciated

  Christian

  Hi Christian,

  The behavior you describe is because the client side PSP buffering is not applied to the Variable API shared in LabVIEW 2009.  It was a design decision, but eventually, we hope to include this feature in a future version of LabVIEW.  This bug here as you pointed out is the lack of documentation for it.  Corrective Action Request # 202159 has been filed for this issue.

  Let me know if you need assistance working around this issue.
