• allocation of an array of 2d in labVIEW and move to the DLL function to obtain data

  Hi all!

  I searched a lot about this, but one cannot find any solution. Please find attached the vi that I try to get a unit of 32 channels data,

  100000 samples per channel with 14-bit resolution. And please also find enclosed the header for my dll file. (in the header, it is the GetBuffers function).

  There is not a lot of data, it is a little more then 6 MB in the task of LAbVIEW Manager eats about 30 MB more memory, then it should. Are there explanations why?

  Because there is much more data in a single channel (million samples or more)

  Then I will try to allocate a 2D to data array, but when I try to run my LabVIEW vi crashes.

  Could you please help?

  Best regards

  Tomzi

  Dear Tomzi!

  To allocate the data in a table in LabVIEW, you must always initialize, as in a you must have a valid entry on cell (x-, y - 1) have a size of table of (x, y). It is usually best to use the function Array initialized for this purpose.

  There are ways to pass arrays 2D to DLLs, cand find you examples of both in examples > communicate with external Applications > external Code using the > integrating DLLs > DLL.vi call. Basically, LabVIEW can pass in the form of a big table 1 d 2D tables, so you'll need to spend too much table size index it. If you pass the array 2D handles it is preferable to use the typedef that LabVIEW generates for you, something along the lines of

  / * LabVIEW created typedef * /.
  
  typedef struct {}
  
  	Int32 dimSizes [2];
  
  	Double elt [1];
  
  	} TD1;
  
  typedef TD1 * TD1Hdl;

  I hope this helps.

• Call the library function does not find the DLL in the directory where are my LLBs

  I'm using LabVIEW 8.6.  I have a set of screws in several LLBs.  All LLBs located in a directory.  Most of my screws is wrappers for the functions in a DLL.  I was told to put my DLL in the directory where are the LLBs, and apparently this is how the previous programmer has worked (using an earlier version of LabView).

  In the configuration of the library call, I've specified .dll without path.  (This is how we want our screws are an API that will integrate other programmers, so I don't know where they put things and I can't use absolute paths).

  When I insert the VIs in LabVIEW, LabVIEW can not find the DLL and wonder of spotted.  It's just that here in the directory with the LLBs and when I double click on it, everything works fine.  However my absolute path to the DLL now appears in the library to call configuration, and we don't want that.

  Does anyone know how to make this work?  I guess the location of the screw (or LLBs, in this case) should be the current directory and thus Windows search there for the DLL.  However, it seems that this is not the case (in the least, in the latest version of LabVIEW).

  Thank you.

  Well someone using your library should not have to dig into your screws and do it all on his own. Instead your library must wrap that and hide disorders it altogether.

  The cluster of error has been added when the dynamic path option has been added. It is not useful hide this error output, so it's always there. As well as the dynamic path, there was the improved error handling added the CLN. One of them is that the level of verification when calling function errors (exception handling) can be specified. I guess that some of these options may generate an error code instead of bring up a dialog box, as they did before and that the output of error code can be useful even in the case of static calls.

  As to what you want to do, I would have long managed that with a DLL that has essentially the same functions as your other wrapper DLLs and an initiliasation function that returns a pointer to a structure of functional distribution based on the actual DLL you want to call. Quite like what an object-oriented function dispatch table is. Then, when your interface initilising you call initialize function and specify the device interface/type that you want to use and after that all other functions take a pointer extra function parameter expedition as the first parameter, in addition to the parameters of the real function. This dispatch function pointer would be just a pointer to a structure that contains the table of function for this interface pointers and the sake of LabVIEW would simply be an integer of size pointer.

  The wrapper function then checks the pointer structure validity send feature and call the actual function with the remaining parameters. It is a C programming and may require a planning and desigining the different interfaces to facilitate this kind of technique of the expedition, but it will certainly pay to long-term and make your library even can be used in previous versions of LabVIEW, so that VB etc. without delicate dynamic loading in the level high, programming environment.

• Really slow Mac Mini on the first commissioning

  I bought my Mac Mini because the old PC had an age to start up. Now, my Mac Mini is even worse. I also have an old portable (2010) I installed Windows 10 on, and it is much faster than my Mac! W10 is up and running on browser/email before Mac even gets to the user login page!

  Advice on other posts, I ran EtreCheck and updated a printer with the HP software problem. Got sorted and it really helped. But its just as bad party, ran EtreCheck again, the results below, but while the Mac was still loading up, it's done intentionally to see if I can find what it keeps. There is nothing obvious in this, can we see something that miss me it please.

  (Aware there are other posts like this but saw someone do an admonition to add their isses at the same post accusing them of 'thread-jacking')

  I suggest you remove the Avast software according to the instructions of developers. You need anti-virus software on your Mac and often through other reports Avast here seems regarded as a cause of potential problems.

  If you do remove it, restart the Mac and the test. If it makes any difference once Avast is removed, you can always reinstall it if you feel that you need (even if you haven't).

• Mac lost during the installation of windows

  When installing windows on a MAC, I deleted my partition mac completely and I am now left with windows 7 to my mac book air. Y at - it an option to install mac, I don't mind losing the windows partition

  Hello smarthala,

  Thank you for using communities of Apple Support.

  I see that you deleted by mistake your Mac partition during the installation of Windows. The partition itself deleted or was it the Mac OS that has been erased, leaving an empty partition?

  If the latter, you can reinstall OS X from OS X Recovery. See this article for how that should be done: On OS X Recovery
  Otherwise, you can use Internet recovery (Command-Option-R, as opposed to the command-R) to repartition the entire hard drive and install the version of Mac OS X provided on your Mac. Who is finished, you can upgrade to El Capitan via the App Store > bought.

  Best regards.

  Hello

  Main differences are:

  • Up to 12 hours of battery life with Powerbeats3, which use chips to W1 Apple energy-efficient (vs. up to 6 hours of battery life with Powerbeats2).
  • A quick charge of 5 minutes for a typical use of an hour (vs 15 minutes to load).

  #1: When I try to print the selection page in Firefox on my Mac, it prints the selection where it appears on the page.

  Yes, this can be inconvenient in some cases. One solution is to remove the other content on the page and then print the selected content normally (instead of using selection). To remove the content, you can use this extension:

  https://addons.Mozilla.org/firefox/addon/Nuke-anything-enhanced/

  As shown in the screenshots on the page, right-click on the selection and choose delete everything else.

  #2: In the menu printing, there is a section of frames that is shaded by the selection of "as defined on the screen. How can I change this setting?

  If frames section is dimmed, which indicates that Firefox did not detect frames on the page. Most sites use no frames, although many use iframes (inline frames). If you need to simply print the contents of an iframe, try right-clicking on the framed area and use

  Hi sonalnj,

  I understand that you cannot synchronize your iPhone as iTunes is requested it must be updated. I can help you with that.

  According to the technical specifications for a 6 s iPhone, you need a Mac running OS X v10.8.5 or later version with iTunes 12.3 or later. Because you are on OS X 10.6.8 your version of iTunes is up to date with this OS.

  iPhone 6 s Tech Specs
  http://www.Apple.com/iPhone-6s/specs/

  Now to fix that, you need to update your Mac OS X 10.8.5 Mountain Lion or OS X 10.11 El Capitan. If you want to go to the Mountain Lion, you can do it with the first link below. The cost will be $19.99 and a code will be delivered to you if you can download it via the Mac App Store. Once you have upgraded, be sure to make all software updates to go with him to get the latest version of iTunes.

  Now the other option is to move to OS X 10.11 El Capitan, and is a free update that you can do right in the Mac App Store, if you meet the system requirements. Take a look at the following article for more details on how to do it.
