• How to include a .lvlib in a generation that was created using a custom .dll file

  I am trying to build an executable in LV2010 which uses a .lvlib which was created using a Keyence .dll file. I added the .lvlib to the source as "Still included" files and I also added all the files "Always included." library .vi I always get the error message saying "Lack the external function" during the execution of the program. The executable seems to open properly on the development computer, but not on a secondary computer. Any ideas?

  Hi Harris,

  I would like to clarify a few points.

  -With all these configurations that you described above, the executable file worked properly on the development computer?

  -L'application works correctly on the development computer outside a build specification, just running in LabVIEW?

  -Have you tried to deploy the executable on multiple computers, and you see the same error on every computer other than the development computer?

  -Is there a software that must be installed so that the TMIF.dll to work? This software is installed on the deployment computer?

  It seems that the DLL is included with success, but for some reason, the function appears as missing. Also, I noticed that the error message has a: C at the end of the message, which makes me wonder - is this a C DLL or a Windows DLL (.NET)?

• Impossible to use first MSVCP110.dll 14

• How to use in LabVIEW DLL of the third

  Hi all

  Using maxon EPOS 2 (positioning system easy) to order the EC motor. It comes with Windows 32 - Bit DLL for labVIEW. How to use these anointings of library in labVIEW correctly? When I try to call the function of library in a LabVIEW program, it shows me a warning about a caller and if the Subvi is not executable. Do I have to change the location of files library or make any other change?

  Have you seen the KB: program a control EPOS of Maxon use LabVIEW ?

• use a C++ DLL in LabVIEW

  I have a DLL that has been written in C++, and the typedef in C++ code is defined as:
  CY_BUFFER
  Definition
  typedef struct
  {
  int size;
  char * data;
  } CY_BUFFER;

  There is a function that should return the number of version as shown below:

  C function
  Version CY_INT (CY_BUFFER * buffer);

  A sample of code C to write to call the DLL is listed here:
  Example in C
  #include "cy_runtime.h".
  const int CUDA_DEVICE = 0;
  If (Initialize (CUDA_DEVICE)! = CY_SUCCESS)
  Returns - 1;
  Buffer CY_BUFFER;
  If (init_buffer(&buffer)! = CY_SUCCESS)
  Returns - 1;
  If (version (& buffer)! = CY_SUCCESS)
  Returns - 1;
  If (free_buffer(&buffer)! = CY_SUCCESS)
  Returns - 1;

  I have built wrapper LabVIEW using the DLL import wizard, but may not know what I have to do. I read the pointers to C/C++ dll dereferenciant in LabVIEW, but I do not understand how to use. Y at - it someone who can point me in the right direction here.  I can't edit the C++ DLL, but I don't know in theory, only the types of data, I just may not know what the wizard trying to do when he created the GetValueByPointer VI code it generates automatically.  If its C++, do I need to not use the wizard at all and create from scratch?  Any help would be appreciated gratefully.

  In addition to what Nathan said, you probably have an alignment problem. C compilers tend to align the elements in a struct to their inherent normal size. This means that the char pointer will be aligned to 4 bytes when you use LabVIEW 32 bits and bytes 8 when you use LabVIEW 64 bit. Now since the DLL also provides the init both the free function, this makes things a little easier. You can simply create an array of 4 integers from 32-bit bytes, pass it as a pointer to array to the function init() and version() free() and the only thing you need to do before release called an additional function of MoveBlock() where you adjust the offset in this table for the number of bits of LabVIEW.

  

  This involves a number of things:

  (1) your struct is indeed using 8-byte alignment, which causes the pointer to the byte offset 4 in for 32-bit LabVIEW and structure at byte offset 8 for 64-bit LabVIEW. Are you of any changes by using 64-bit LabVIEW, now that you have these 4 additional elements of the cluster between the size and the pointer?

  (2) in fact, the size in the struct element specifies how much data is in the buffer tank.

  And for the functions of the DLL error handling was completely omitted. To match the C code, you have shown that you should always check the function returns the value too before continuing.

• Cannot use MATLAB MCR DLLS in LabVIEW

  General information:

  We would like to call a Matlab compiled DLL, which is based on the duration of the compiler Matlab (MCR), LabVIEW. We also want to use the LabVIEW Vision of data collection software. Use a map OR frame grabber is installed, and a camera is connected to the card. We were using an evaluation version of LabVIEW to see if you can solve this problem. We tried two versions of LabVIEW 8.6 and 2010.

  The problem:

  The installation program of LabVIEW place dll in the system32 folder. The names of some of these DLLs are generic enough. LabVIEW vision software includes tbb.dll in the System32 folder. Execution of the Matlab compiler also includes a tbb.dll, not in system32, but in it's own application directory. LabVIEW DLL / so everybody, which is kind of rude, but little matter which at the present time. The biggest problem is when I try to use Matlab in the same process as LabVIEW Vision. It is not possible to do so, because the names of DLL in conflict between them, and I have no control over the source or Matlab and LabVIEW code to allow them to be charged with the full path name.

  For this reason, we can use the LabVIEW software to solve our specific application.

  Hi marcus,

  R & D is aware of this problem and it has already been established as part of the Corrective Action that requires #245249. You can watch the future versions of LabVIEW release notes to see when it is fixed.

• Using a C DLL with complex numbers of Labview

  Hello

  So I would try to use the existing C99 to perform calculations, and for the functions code, the code accepts and returns type numbers 'double complex.   I have spent half a day to find out the hard way that Visual Studio does not complex.h header, so before you spend more time trying to compile a DLL, not done Labview even allows you to send and receive complex of a DLL call numbers?

  When I open the node to call a library function and go to settings, the closest return type I see is double 8 bytes, but nothing about the complex... so...   I am not even convinced that this will work... did anyone done this before?

  Thank you

  Yes, you can use complex numbers. See the example with properly called LabVIEW "" call DLL". There is an example here that deals with complex numbers. You may need to write a wrapper DLL, if.

• I would like to only convert a c++ for use in labview dll - my camera has no DLLs in labview

  I have a piezoelectric Control Board (Piezomechanik gmbh) that I would use through LabView.  Currently, the company offers no support for Labview.  Windows detect the device (it came with a driver file), but the company only provides for C++ and Visual Basic dll files.  Can I convert these files to a format that can use Labview?  How can I get Labview to communicate with the control of Narcotics (and ultimately the piezoelectric device attached)?  Thank you!

  This will help you only when you have the header for the DLL file, otherwise you have to create manually using the "call library node' and the description of api DLL wrapper or write a header file for the DLL yourself based on the documentation of the api and the wizard.

  Kind regards

• Random processes using 50% CPU (dll files)

  Random process (svchost.exe, taskhost.exe, taskmgr.exe procexp.exe - Process explorer, chrome.exe, skype.exe and so forth) always use 50% CPU, but only one of them will do both. If I stop the process that takes too much CPU usage, after 5 seconds, another process starts using 50% CPU again. I used Process Explorer to check the problem, and I found that the process still using 50% CPU has api-ms-win - returned-* dll running (from 4 to 9 of the dll). No other process has them. After that I started to close the processes one by one and always monitor the dll, and it seems that after I stop a CPU consuming processes, after a few seconds another process loads the api-ms-win - returned - all * dll and start again using too much CPU. I don't know if the CPU usage is relevant to these DLLs, so I came here to help.
  I tried to reinstall windows, use 2 anti virus to find something and neither things solved the problem.

• How many DLLs can use a sequence?

  I created a class / DLL (FOO. (DLL) which is implemented by a file of sequence via the TOOLS menu on measure.  The version "hello world" of this DLL works fine.  When I update this DLL to use classes from other classes / dll, I created (BAR. (DLL) I get the error: has no load file or Assembly BAR, Version = 1.1.0.0, Culture = neutral, PublicKeyToken = null' or one of its dependencies. The system cannot find the specified file.

  I added to the bar. DLL directory to the list of Configuration-> directories of research... and of course its check box has been activated, but he has not made a difference.

  Is a DLL that is activated by a sequence file allow the use any other dll 'home-made '?  Or must be a DLL activated by a completely self-contained movie file?

  The .NET assemblies depends on your specified assembly loaded by the algorithm of the .NET framework to find assemblies, not the search directories TestStand. They are not directly loaded by TestStand; they are loaded by the .NET
  framework. Generally, the .NET framework will find dependent assemblies if they are in the same directory that your assembly is specified, in the application base directory (i.e. the directory of the executable), or in the GAC.

  Hope this helps,

• EvaluatingTteststand 4.2.1: Null, an access violation (error 17502) pointer when trying to use a std::map mixed mode / push shared_ptr class contained in a DLL interface from a different DLL

  Hello.

  I worked on a test system that will potentially TestStand to its base and downloaded/installed the 4.2.1 assessment. The latest information of the information dialog box are:

  TestStand engine version 4.2.1 (4.2.1.83)

  Verison 4.2.1.83 sequence editor

  The system will push mobile radio using interfaces serial RS232 devices, usnig a variety of protocols series (Hayes and some protocols binary owners for other work).

  We already have in existence, a tester of soaking, written unmanaged dll in VS2005 with MFC and also managed dll that is mixed together to provide the different aspects of the functionality required for binary protocols.

  I created:

  1. a "wrapper"master"DLL for the constellation of the other dll - it offers a simple C API interface that I hope TestStand will use. "We call it"SerialSessionMgr.dll"

  2. a mixed managed / unmanaged "IJW" (it works) DLL that wraps Protocol binary log control interfaces, which are entirely management C + c++ / CLI: DLL calls "master" wrapper"this as an unmanaged interface to create instances of the class compiled by CLI which interfaces to the underlying managed dll imlpementing protocol logging. It's called "WinTseInterface.dll".

  Until I started evaluating TestStand, I struck up a test harness using CPPUnit / MFC, with which I could test SerialSessionMgr.dll and its ' use of WinTseInterface.dll and check that they worked. The sling load the DLL dynamically at runtime using AfxLoadLibrary() trying to emulate the TestStand way he uses.

  When we opened a TSE session:

  1. The SerialSessionManager made a call to the WinTseInterface.dll to 'create' an instance of logging. The instance is created in a std::map held by the CWinApp derived class, this map contains boost::shared_ptr of the class that works with a managed class. So we have a record of appeal: Client app-> SerialSessionManager {TseStartSession ()}-> WinTseInterface {WINTSE_GetWinTseBridge ()} - just WINTSE_GetWinTseBridge() creates a new instance of the unmanaged class through the managed CLI/C++ class interfaces slot, which returns the address of the SerialSessionManager, that stores.
  2. The SerialSessioManager actually initializes the WinTseBridge using a method of a class of virtual interface implements pure C++ class in the std::map in the WinTseInterface DLL. The call to initialize passes various details and actually called 'New' to create the managed class which of your interfaces to the underlying managed DLLS that implement the protocol logging.

• Which DLL to use for the use of NOR-PCI-6703? (nicaiu.dll or nidaq32.dll)

  Hello! I'm programming ATEasy (from Geotest Inc.). I have to incorporate a Council OR-PCI-6703 and I need the driver for it. I do not know what .dll file to use: nicaiu.dll or nidaq32.dll. What is the difference between these 2 files? What is the best for me to use? Please help me!

  It depends on if you use the traditional DAQ driver or the driver DAQmx. If you use the DAQmx driver you want to use the nicaiu.dll. This link will explain the necessary information to be able to use for your application.

• using NI USB-6008 with libraries .dll

  I am trying to write a program that can run on a computer that does not have the 2 GB of drivers using the included dll. (NationalInstruments.DAQmx.dll, NationalInstruments.Common.dll, NationalInstruments.Common.Native.dll) I have an operational programme that is able to use the outputs and inputs on a computer that has installed the drivers to read, but will not work on a computer that does not install the driver. The driver is an absolute requirment for the program (and the camera) run?

  Yes, the driver is necessary to use the DAQ hardware. You may be able to reduce the installation a bit, but I don't know how small you can get.

• Report to DENY using LV 2011 built dll crash

  I have an application that uses a built DLLs LabVIEW.  LV dll is called by a dll ActiveX component integrated into VS 2010.  The dll of the LV was origninally built using LV 2010 and worked well.  When we build the same application using LV 2011, everything works up until the closure of the top-level application.  We are then prompted with a dialog box telling us that a failure has been detected (journal text below).  The error occurs if we use static or dynamic linking to the dll.  If I disable DENY it to the application, there is no problem; If as we use a component ActiveX, I must create a for the calling application ini file or disable the DENY for the entire system.  None of these options is desirable, because we cannot know all applications that could use our ActiveX module and cannot control each system we will be deployed on.  If we do not find a work around that, we will have to go back to LV 2010.

  I think I've solved my problem, which I will describe in the case where the same thing is happening to others.  The root of the problem, near as I can tell, had something to do with the appeal of the LV dll of in another dll. For some reason, when I linked statically to the dll, the DllUnload process caused this crash report.  I found evidence to suggest that this can occur when you unload a dll from in the process of unloading in another dll on the web; as is the case with static linking.  When I tried dynamic link, I initially tried to use a global instance of the HINSTANCE dll who got charged and discharged with the WinApp object, the result would have been basically the same.  If I connect dynamically to the unload dll event and explicitly the dll before the call dll being unloaded, the problem disappears.  My calling dll is an ActiveX application, I tied to the instance of the dll to the COM object rather than the object WinApp.

  Still don't know why it's a problem for LV 2011 and not 2010 LV.  Perhaps the 'crash' still past and just has not been reported significantly since the app was close anyway.  I'm not sure.  Anyway, hope this helps people out there.

• I am not able to use the DLL

  Hi all

  I'm developing an application using LabView 8.6. I took the .net DLL reference. I have modified the DLL and tried to access the method I added in the DLL. But take when calling node, I have not found the new method. Then I copied the DLL to another folder from the new location reference. But it is made reference to former DLL and I get message "the version of the assembly, you have requested is automatically promoted to a later version by the .NET runtime". Also, in the dialog box select Builder .NET I can see the two DLLs.

  Please suggest the way so that I can be able to use the new DLL.

  Thank you best regards &,.

  Hi all

  I can be able to use the modified DLL after reboot of LabView. I think that LV guard reference DLLS used even if that we close the VI.

  Thank you
