• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.

• Stream of 6537 s on the drive with another card as well.

  Hello, we are planning to have a platform that has 3 PXI 6537 s and another card for playback of a sync signal (North Atlantic Instruments 75 3). We capture cards PXI 10 MHz and the 3 75 between 10 and 20 Hz, regardless if we taste a bit faster than that, but we can't go much more slowly. We need to store the result in a known file format so we can analyze it later.

  From the example of reference for data streaming of double PCIe 6537 s example of disc (http://zone.ni.com/devzone/cda/epd/p/id/5315), it seems simple enough to add another PXI card.  We are OK with that.

  What is the best approach to take the card sync?

  Our first choice is so far:

  To read a value from the sync every time it happens around the loop of the producer; i.e. every 20ms. This will taste at 50 Hz, but that's OK. Store us the values in a table of fixed value size zero and push the table on the queue at the end of the case 'true '.  It's easy enough but... The 3 1 d Raw U32 DAQmx readings work quite quickly to allow the Syncro values to the queue, in the 20ms window? (We have operated there should be about 16 MB of data per card for each reading). If not, is it close enough that he could be twisted so that sync data can be queued as well?

  Our second is:

  We plan to read data in sync in a zero arbitrarily large array initilized, especially if we know the size when write us data to the file. This can be filled at 20 Hz, in what I'll call (or the love of argument) a producer of the second loop. We could protect access using semaphores. In the loop of consumption, we read the three blocks of data, then data sync; That is to say:

  • read three lots of the queue database
  • lock the semaphore
  • write the content of the table
  • zero the content of the table
  • unlock the semaphore

  Does anyone know of a decent/better way to do this?

  Are we on track?

  Thank you

  Jon.

  Hi Jon,

  Yes, I think that your hypothesis is correct.

• 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.

• Unable to read the security descriptors data stream

  Whenever I start my computer runs CHKDSK - it says checking file system on E: and then he said that it should be checked for consistency. It works until stage 3 when he says 'impossible to read the security descriptors data stream' how to fix this?

  I tried chkdsk e:/r and it runs before step 3 when I get the "unable to read the security descriptors data stream" and it goes no further.

  I also tried fsutil dirty query e:- but it says something about a parameter incorrect and not if the volume is dirty or clean.

  Then I tried chkdsk e:/f/x - that always gives me the same mistake about it being an incorrect setting.

  As far as I know there is absolutely nothing on E:, I didn't even know that there was an additional drive. Right now I have it turned off so that I can use my computer. It seems to work fine without it. I read an article that said that if I can't fix e: with chkdsk which I have to do a low-level format of the reader? What's my next step? And I can do without the XP disc?

  The syntax

  fsutil dirty query e:

  is correct (except, of course, you try to use from the Recovery Console, where the fsutil command is not available).  Are you logged on as a user with administrative rights when you use fsutil?

  Similarly, the switches /f and/x are not available for chkdsk in the Recovery Console.

  See Recovery Console controls.

  Click on desktop then right-click on E: drive icon and select Properties.  What is indicated for:

  • File system
  • Space used
  • Free space
  • Capacity

  Now double click the icon for E: are shown files?  If not, click Tools > Folder Options > view and select the radio button "Show hidden files and folders" and uncheck "Hide protected files (recommended) operating system.  Now that you see all the files?

  Everything you read 'low level of shaped' is nonsense.  Any modern PC drive cannot be low level formatted by end users.  You can read this, but there is really no necessary even to "zero fill" your drive E: http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=203931 (I have not checked to see if the WD tools rescuer has similar characteristics to SeaTools for DOS).

  If you are convinced that there is nothing of value on E (for example, installation of backup or restore), you can either format by right-clicking on the drive icon in my computer and selecting "format" or you can start disk management as described previously and use either in electronic format or delete the partition completely.  If you delete the partition, space becomes "unallocated".

  Because I guess C is your system drive (where Windows is), you may be able to use the diskpart tool to extend the partition F to use the unallocated space left if you decide to remove E well it's much easier (and safer) to do with disk management third-party tools such as Easeus Partition Manager free : http://www.partition-tool.com/personal.htm

• network data stream

  Good afternoon

  I need to send the data generated in the vi, by network data stream.

  The problem is that I found no example that does something similar, and this is my first time using Activex with Labview. Can someone explain me how to send Activex data via the network stream please and if possible help me find a solution to the attached vi.

  I think I need to convert the data somehow after control of the room before using the writing and reading items, I tried with strings and arrays unsucessfully, I really think I'm missing something.

  Thank you in advance!

  Erika

  Erika,

  What do you think?  You try to play an .avi file, a .mpg or what?  IMAQdx has functions that can play video and output files 'images', and you can deliver these images via TCP/IP on another computer using network flow.  Indeed, there are cameras that capture video and output via TCP/IP - IMAQdx is used to capture the image directly from the camera and can view or save a file from .avi (for example).

  You have the Vision Module installed on your system?  In your Palette of block diagram, it will appear under the Vision and movement and should include IMAQ (or IMAQdx) and utilities of Vision (which contains the Palette under files to make the reads and writes of video files).  See if you can use this to display your video...

• NTFS alternate data stream

  Hello:

  I am trying to write a code that works with other data in NTSF streams. Similar to this Microsoft makes This example . The attached VI is a simple example of code - open the second stream "metadata" and write something. However, open them VI LabVIEW (2009 SP1) always returns error when I try to open the stream.

  So, he knows that LabVIEW (at least 2009) does not work with NTFS streams? If possible, please tell me how.

  Thank you

  -Ilya.

  Ilya,

  I agree - ADS is tantalizing close to a very elegant solution.  I hadn't really looked at their use for something useful - I always considered them a breach of security and a hold-over of formerly Mac resource fork.

  Another suggestion that may or may not work for you:

  Have you looked into the TDMS files?  They were designed to be a solution to this type of problem - if you don't have to sacrifice performance for convenience to keep everything together metadata is stored with the binary data.  I think that how LabVIEW implements TDMS read and write is faster that in general, you would be able to achieve since we are able to bypass some of the regular windows caching etc.  TDMS is not specific to LabVIEW but to be able to open files in Excel or offline like DIAdem analysis tools.

  You can find more info about TDMS here if you're interested - http://zone.ni.com/devzone/cda/tut/p/id/3727

  In any case, good luck.

• Defining the new path for the data files for restoring using the VALUE of NEWNAME FOR DATABASE

  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -----------| Holy Cow |-----------------------------
  
  
  So I had to rename each file as below
  

  $ mv 1 /fnup/hwrc/oradata/spikey/system01.dbf
  $ mv 2 /fnup/hwrc/oradata/spikey/sysaux01.dbf
  $ mv 3 /fnup/hwrc/oradata/spikey/undotbs01.dbf

  I would have been better in execution of the order for each data below file

  SET NEWNAME FOR DATAFILE

  Now, I think, there is no advantage in using NEWNAME SET of DATABASE to. Only the disadvantages. I did anything wrong above?

  Martin;

  On the issue of the VALUE of NEWNAME FOR DATABASE, you must specify at least one of the first three of the following substitution variables to avoid collisions of names: %b f % U. see semantic entry for TO 'filename' for a description of the possible substitution variables.

  You use %f

  %b
  
  Specifies the filename without the fully qualified directory path. For example, the datafile name /oradata/prod/financial.dbf is transformed to financial.dbf. This variable enables you to preserve the names of the datafiles while you move them to different directory. During backup, it can be used for the creation of image copies. The variable cannot be used for OMF datafiles or backup sets.
  
  %f
