• Call any thread DLLs the application crashes

  I have a built in 2015-labview application that acquires spectra of 6 spectrometers via an external dll. The dll triggers an event in labview when data is ready to be pulled from the spectrometers. Since this event, I am running a reentry no void / vi which contains a node function to retrieve the data, that are configured to run in any thread, as it gives a drastic improvement of performance as apposed to run in the UI thread.

  However this can slow down the application crash with a message from windows like the following journal:

  Name of the failing application: axiom 2.0.exe, version: 1.0.0.82, time stamp: 0x5581a6b7
  The failed module name: lvrt.dll, version: 15.0.0.4024, time stamp: 0x5581ac03
  Exception code: 0xc0000005
  Offset: 0x0000000000bec7c0
  ID of the process failed: 0x15c0
  Start time of application vulnerabilities: 0x01d11e6face9febd
  The failing application path: C:\Axiom 2.0\builds\Axiom 2.0\Axiom 2.0.exe
  Path of the failing module: C:\Program NIUninstaller Instruments\Shared\LabVIEW Run-Time\2015\lvrt.dll
  Report ID: 7d4ef3a8-8a91-11e5-94e9-90b11c894ef8

  I don't know if the dll is said to be thread safe or not. Also I do not understand how this causes a problem anyway since it is the only node that accesses the dll at the time, and each of the 6 spectrometers are interviewed in order?

  Is there anyway that I can still enjoy the benefits that the call of any thread dll provides without causing my application crash.

  An example of the increase in performance, it's that I can query the spectrometer from 6 to 70-80 Hz when configured to run in any thread, as opposed to a simple 10 Hz when the Run value in the UI thread.

  Thank you

  Looks like that the DLL is not thread-safe. If you do not run in the UI thread, there is no guarantee that the DLL will be always called from the same thread, even if you only call it in one no reentrante Subvi. By default, LabVIEW allocates multiple threads by the enforcement system, with the exception of the user interface. If the DLL stores certain information of one call to the other, this context can be lost when run in a different thread.

  Here's a thread that provides two possible solutions; a wrapper DLL is required, use the other the utility 'threadconfig' (or the corresponding INI file settings) to force a subsystem of a thread executing unique http://forums.ni.com/t5/LabVIEW/Force-DLLs-to-tun-in-the-same-thread-expect-the-UI-Thread/td-p/11438...

  Another option would be to put the call to the DLL in a timed loop that runs constantly, and you can use a queue or the notifier to pass data to. A timed loop runs in a single dedicated thread, so I think it will work.

• How to call windows dialog boxes

  Hello

  I just want to know how to call a windows dialog box, I called below the dialog using VB script and the script is the following lol = msgbox ("Your Message here", 19, "Your title here") and save it as a .vbs file, by changing the number "19" in the script to generate the different dialog box. And I think it is called by the user32.dl of windows.

  So can you please help me to call the dialog even in labview.

• How to call and parse the SOAP WSDL service in Swift 2.0 to Xcode 7.1

  I'm new to the SOAP and I don't know how to call SOAP Web service and parse XML. I also tried to try to Google.And all of the resources that I had was outdated. Y at - it a tutorial or examples that I can learn? Any help?

• The DLL call fails when DLL uses a wide range

  I call a C++ dll in LabVIEW 32-bit on Windows 7. I kept getting error 1097 and finally understood it is because the dll uses two large paintings of 5 MB each. The tables are initialized in the constructor of an object, malloc is not used, or whatever it is. If I do the smaller berries, then everything works fine.

  The problem is not difficult to work around, now that I know what is the cause, but can someone tell me why a dll using a lot of memory would be a problem? I feel that 10 MB is really a lot of memory to use on modern computers.

  OK, you can test the appeal of the DLL in a Visual Studio test harness?

  In addition, in case you haven't seen another 'DLL error 1097' son type, here are a few. The cause of 1097 in your case can be illuminated by a multitude of courses of troubleshooting:

  Call dll error 1097

  Error code coming 1097 in DLL call

  error 1097 after the call dll function that allocates memory inside

  1097 error in the transition from table from C++ DLL for LabView (seems very relevant, although long)

  I know there are a lot of reading, but there is a good chance that the magic trick is in one of these threads already. We will ride on the shoulders of their work.

• How to call a second instance of the same VI?

  Hello

  I have a useful VI dealing with IO operations. To save some time, of what I would call the VI as a second instance do work at the same time. I created a sequence sub with the run option 'Use the new thread' and I called the Vi (a step of the sequence only). Execution time of the VI is about 20 seconds run Durin I called the subsequence and I carried on running my main sequence (parent). Since then 10 seconds to launch the subsequence (in the thread of sepatate I called the same VI as in the thought of subsequence the second instance will be created. However, instead of parallel work of the two instances of the same VI had to wait when mt subsequence end known call the VI th.

  So my question is, as in the topic: how to call a second instance of the VI even at the "same time"?

  Could you please tell me about the best approach to solve the problem?

  Any VI that you want to run in parallel must be paid also re-entrant, including screws.

• LabVIEW crashes after the call to the DLL

  Hi all

  I'm working on writing a wrapper for a dll. The call to the dll works fine a returns the appropriate values, but as soon as I close the VI dev LabVIEW environment crashes. Any help to avoid the same. I've been through a lot of posts and I tried varying the types of data sent to the dll, but again it gets crashed.

  the dll function that I use is the prototype (with the calling convention of type C)

  int nomfonction (Struct * cfg, UCHAR dNumber, UCHAR hTYPE)

  The varables UCHAR I'm passing as of 8-bit unsigned integers.

  For the structure, I did a cluster and pass with adapted to the Type and handles.

  The DLL is running very well and the VI stops, too, but as soon as I try to close the dev environment VI crashes. Help, please.

  Thank you.

  It is always possible that there is a bug in your DLL, or you're a failure calling a function in the DLL that is required in order to properly clean. The problem is perhaps not the way you have set up the call library function node.

  If you post: your VI; the header file that defines the structure of the cfg and the function prototype; and all the documentation on the function, so we can tell you if it is properly configured. Without this information there is little we can do.

• Timeout on a call to the DLL

  Hello

  Does anyone know if there is a way to force the DLL to timeout call?  I have a DLL that I wrapped with screws but on some of the methods, there seems to be an internal timeout hardcoded I need to reduce but now I'm stuck until the end of the call to the DLL and I therefore expect this internal time-out that is ~ 35sec.  Thank you.

  It is impossible to interrupt a call to a DLL. A call to a DLL never times out. the DLL function must be completed in order for the ongoing enforcement.
