Visual Studio Message Cluster LVUserEvent

Hi, it is possible to use a queue to exchange messages between a .dll and LabVIEW? Yes. Cheque image.

It is posilbe that the data contained in a variant of the cluster and are? You can convert a given variant in .dll and convert a Variant labview data for data?

And I tried to implement a function with the following code, but I made a mistake when I run LabVIEW.

#pragma pack (push) 1.
typedef struct
{
LStrHandle newStringHandle;
LvVariant * data;
} MessageCluster;
#pragma pack (POP)

...

Message MessageCluster;

...

PostLVUserEvent(*rwer, (void*) & Message);

Thank you very much.

No, the Variant C API is not documented and so there is no way to create, query, modify or otherwise use from C code, if you are not a developer of NOR. Use the documented data types.

  • Run the CVI in Visual Studio code

    Hello world

    I tried to get a CVI code to run in Visual Studio using this guide (http://zone.ni.com/reference/en-XX/help/370051V-01/cvi/usermanual/prjbldmenuextcomplrspt/). So far I've managed. However, I was faced with a non-fatal errors. Apparently, Visual Studio is not following them. Also, fatal errors do not produce a meaningful error message. Is there a way to get these error messages from inside Visual Studio? Maybe there is that an event reminder/whichI can use.

    Thanks in advance.

    The feature you describe is called "user protection". In addition to reporting the pop-up windows error codes, it also warns you if you access an invalid memory, data types to pass to functions that expect different data types, detects local variables uninitialized, etc...

    Unfortunately, the protection of users only works for programs built in debug mode using the CVI compiler. If you generate your source code in Visual Studio, the compiler VC injects not the information necessary to protect the user from working.

    The only way you could get this works in Visual Studio would be if you could somehow isolate all your CVI code in some DLL that build you with CVI, then call this DLL from the rest of your program, what you have created with Visual Studio.

  • Unit test, Visual Studio 2010 digital input read event

    Hello!

    I have problems in Visual Studio 2010, using NOR-DAQmx, but ONLY in a unit test project. I have compiled a dll that uses a DigitalChangeDetection task handler. The dll work very well in a draft standard form, but does not work in a Test project.

    I used .NET Framework 4.0 with success. Tried to switch to .NET framework 3.5, but it is not possible for a test project in Visual Studio 2010.

    When I start my test, it works fine until the event is raised. Once he does, the test will stop without exception or detail except the following result:

    "The agent process was stopped during the execution of the test."

    Nothing is caught in the trap in debugging.

    Also, I get the following in the Event Viewer error message:

    Log name: Application
    Source: VSTTExecution
    Date: 2010-12-01 11:32:31
    Event ID: 0
    Task category: no
    Level: error
    Keywords: Classic
    User: n/a
    Computer: xxx
    Description:
    The description for event ID 0 in source VSTTExecution is not found. Either the component that triggers this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

    If the event is on another computer, the display information had to be saved with the event.

    The following information has been included in the event:

    (devenv.exe, PID 5592, walk on 73) OutOfProcessStrategy.ProcessMonitorThread: The Agent process was closed unexpectedly. will attempt to restart

    the message resource is present, but the message is not in the string/message table

    The event XML:

        (devenv.exe, PID 5592, walk on 73) OutOfProcessStrategy.ProcessMonitorThread: The Agent process was closed unexpectedly. will attempt to restart
     

    I understand that Visual Studio 2010 is not yet officially supported so here's my 2 questions:

    -I'm the only one experiencing this problem? (Easily duplicated by taking the sample project: DotNET3.5\Digital\Read Values\ReadDigChan_ChangeDetection_Events and extract the relevent part of to put in a separate dll so that you can try to UnitTest in a project UnitTest.)

    -Update on what NOR-DAQmx will rely on VS2010? (I read here: http://forums.ni.com/t5/Measurement-Studio-for-NET/Support-for-Visual-Basic-2010-NET-4-Framework/m-p... this is supposed to be before the end of the year, but no updates would be great because I could not find any information on it)

    Best regards

    Pierre-Luc

    Hello Pierre,.

    As NOR-DAQmx is not yet officially supported in Visual Studio 2010, it is not quite clear why this problem occur. At this point, the official release date has not been announced yet, however, please continue to check the updates to www.ni.com/support (drivers and updates). Thank you

  • wink for IMAQdx Visual Studio 2008

    I am using the sample of component project in Visual Studio 2008, c# snap.  This is the sample project that came with the installation of the software OR.  When I try to capture an image of the camera, I get a message error "interface passed or the session is invalid '.  I checked my name of the interface of the software NOR and that's okay.  I have a Basler A601f camera connected via firewire.

    Any help would be great.  Thank you.

    Ah, which is why you must use IMAQdx to work with Firewire.

    I use mostly LabVIEW to program with IMAQdx, so I don't know what kind of examples are available. I recommend to install the latest version of the software for Acquisition of Vision to get the most recent examples shipped. You can check for errors in the forums or on ni.com.

  • Strange problem with Visual Studio

    Hello.

    I hope to be in the right section.
    For some time (I can't say precisely how much, maybe since I've upgraded to Windows 10) I have a problem with Visual Studio 2013.
    In practice, after a few minutes, what is open (without doing special things, even just type code) goes down. comes the message "Not responding" and I have to restart to continue working (say that work this way, it becomes impossible).
    I tried to reinstall but I have not solved, I have also the same problem even with Visual Studio 2015.
    The strange thing is that this problem is only with my user account, and with the remote desktop, sessions instead works without problem.
    What is the problem?

    Thanks a lot to all

    This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

  • Visual Studio error after installation of the CVI

    Ladies and gentlemen,

    After the installation of CVI (current version), I've got strange message in Microsoft Visual Studio 2005 (appeared every time when I build the solution, for example, by pressing Ctrl + Shift + B):

    I have no integration with CVI in Visual Studio - but where can I turn this off (without uninstalling CVI, of course)?

    Unable to find this in the preferences...

    Andrey.

    Hello-

    To remove the integration of Visual Studio, you must go through Add/Remove programs.  In Add/Remove Programs, select software National instruments, click Uninstall/change.  In the "National Instruments software" later dialog that appears, choose your latest version of LabWindows/CVI and select Edit:

    Then displays the LabWindows/CVI Installer dialog box.  Once it done, choose the Visual Studio 2005 wizards and select Remove:

    Sorry for the inconvenience - let me know if this does not fix things for you.

  • INTEL FORTRAN COMPILE / VISUAL STUDIO FOR THE ASPEN SIMULATION

    Hi all

    I have little knowledge about the use of FORTRAN with application of this on VISUAL STUDIO. In fact, I know about these software because of the obligation for them to rewrite some code I had to rewrite before running on ASPEN Plus.

    My problem is, I want to run a simulation Aspen Plus using the soft articles in question, but I honestly don't know how to go for them, as all this seems confusing. I have already installed the compiler FORTRAN and Visual Studio, but I don't know which platform to extract the entry codes I need to compile.

    The codes that I needed to re - compile in Intel FORTRAN, which is compatible with the Aspen has been compiled previously using Silver frost 95.But FORTRAN, after compilation by using this software in Silver frost, codes does not work on Plus.It of Aspen was a few days ago I learned this can never work on ASPEN Plus Hence the need to install the compatible software.

    (1) what it means to re - write a written code previously in Silver frost FORTRAN 95 or other FORTRAN codes in Intel FORTRAN compiler code and what is the procedure for that?
    (2) after having rewritten in Intel FORTRAN codes codes using Intel FORTRAN compile, how I performs the following steps before finally launching the simulations using Aspen:
    b compile the user model?
    (b) models of the user shared a link in a Fortran Library procedure?
    (c) provide the files objects or shared for the Aspen Plus system libraries?

    Any positive contribution will be highly appreciated.
    Gee right.

  • LabVIEW call DLLs Visual Studio - error - "Debug Assertion Failed"

    Dear Forum,

    I made the wrappers for the c codes ++ writing Visual Studio 2008 for some time. I recently worked with a c++ application.

    However, this time, I get an error expected. Alien, the code calls the dll worked previously. With no retouching, I closed LabVIEW for a few hours, it opened again - and this error message (see below) appeared since. I tried to restart the computer, the Subvi rewriting and checking the prototype of the function.

    Nobody knows what this assertion of debugging message failed try to indicate?

    It seems that when I run the LabVIEW VI when it calls the node library call. It does not return and error boolean as designed in c++ code.

    Note: All other containers of c ++ and LabVIEW code works, but not this one.

    Any advise would be very useful indeed.

    Kind regards
