• 'Invalid Thread access' - WSDL in OSB consumption

  Hello

  Creating a business service I'm trying to define the type of service using WSDL. I get the error "Access thread not valid" with no further details.

  The URI is available in my browser and works when I import it in jdeveloper. through soapUI, I can able to test this service.

  The interesting point here is that I am not able to ping the server. (cmd-> name of ping service). My doubt is here (as to invoke third-party service) should they open any port for us or not.

  Please me tips

• Berkeley DB Java Edition - multiple threads accessing the database

  Hello
  
  I would like to access (read & write) a Berkeley DB of multiple threads (process/FMV anyway).
  
  Can I use a single com.sleepycat.je.Database object for all threads, or should I create an instance of each?
  
  Or is there another way to do it?
  
  Thank you

  The object database can be used by multiple threads, you can use a single instance or multiple ones, as suits you best. Of http://docs.oracle.com/cd/E17277_02/html/java/com/sleepycat/je/Database.html.

  The database handles are free of threads and can be used simultaneously by multiple threads. '

  If you read the javadoc, you can find any other comments on the use of the classes from multiple threads.

• Why error invalid memory access loading newdev.dll

  My wireless device is connected to a usb port. No problem. Any other usb devices that I connect to a usb port causes the error message in the title

  Hi Gene Henley,

  1 did you change on your computer before the show?

  2. Since when you receive this error message?

  Follow the following troubleshooting methods:

  Method 1:

  The newdev.dll is a file system that is provided by Microsoft, I suggest that you try System File Check to repair corrupted system files.

  Check out the following link to run the System File Check.

  Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)

  Note: It can ask windows of difficulty CD and allowing SFC to do more than minor repairs. Could some of the files saved on your computer are deleted when fixing corrupted files.

  Method 2:

  Perform the following troubleshooting steps.

• Control DB access

  Thanks in advance.

• Create a data streaming from C++ stream and read it in LabView

  Hi all.

  I'm working on a project that is to connect to a tracker of movement and reading data of position and orientation of this in real time. The code to get the data is in c ++, so I decided that the best way to do it would be to create a c++ DLL that contains all the functions necessary to first connect to the device and it reads the data and use the node to call a library function to power the Labview data.

  I have a problem, because, ideally, I would like a continuous flow of data from the code c ++ in Labview, and I don't know how to do this. Put the node function of library call for a while loop seems like an obvious solution, but if I do it this way I'd have to reconnect to the device whenever I get the data, which is quite a bit too slow.

  So my question is, if I created c ++ function that creates a data stream, could I read that in Labview without continually having to call a function? I would rather have only to call a function once, and then read the data stream until a stop command is given.

  I'm using Labview 2010, version 10.0.

  Apologies if the question is badly worded, thank you very much for your help.

  This method resembles an excellent suggestion, but I have a few questions where I don't think I understood fully.

  I understand the basic principle is to use a call library function node to access a DLL that creates an instance of the device object and passes a pointer too in labview. Then a separate call library function node would pass this pointer to another DLL that could access the device object, update and read the data. This part could be in a while loop, then continue on reading the data until a stop command is given.

  That's all. I'm including some skeleton for example code. I am also including the code because I don't know how you experience multi threading so I show how you can use critical sections to avoid interactions between threads so that they do not lead to questions.

  My main concern is that the object can get out of memory or be deallocated since it would not take place to any namespace or whatever it is.

  As you create the object with the new, the object expire not until the dll is unloaded or the process (LabVIEW) closes. If the object will remain valid between condition LabVIEW dll calls not a not unload the dll (who does if the screws are closed). When that happens, I don't know exactly what happens to the active objects (that is, if you forgot to call close), I guess the system recovers the memory, but the device could still be opened.

  What to do to make sure that everything is closed when the dll before I could call unloads close and remove the object is whenever I create a new object in the dll that I add to a list when the dll is unloaded, if the object is still on the list, that I'm deleting it.

  I also have a more general question of programming on the purpose of the buffer. The buffer would essentially be a large table of position values, which are stored until they can be read in the rest of the VI?

  Yes, see the code example.

  However, according to the frequency with which you need to collect data from the device you have this buffer at all. That is, if take you a sample on every 100ms, then you can remove all threads and buffer related functions and instead to read data from the read feature itself like this:

  double CDevice::get_data()
  {
      tracker->update();
      return tracker->getRawData(0);
  }
  

  Because you need only a buffer and a separate if thread you collect data at a high frequency and you can not lose any data.

• Variable single process shared w/o (without) FIFO between deterministic loop.

  Hello

  Why we cannot use variable shared unique process without FIFO to communicate between deterministic loop?  In other words, why it is always recommended to use FIFO for communications between the deterministic loops?

  Thank you

  Ajay.

  It is called sharing resources.  When you use a variable shared unique process, only one thread accesses it at a time.  So what is happening is a tent to read, but B is busy writing on it.  So wait, adding a jig.

  With the RT FIFO active, you don't have this problem.  One can read from the FIFO as B adds another element.
