Calling ActiveX function

I am using an ActiveX function that has following format (in C++)
HRESULT GetLuminanceImage([in] long aMax,
[out,size_is(aMax)] float fBuffer[],
[out, retval]short *sRet);
How can I call this function in labview.
I need to know how to define the parmaters in Call library function node in Labview
Thanks in advance.

Hi Lycangeek ,
I got stuck in the same kind of problem , I am using Automation open to load my COM library.
My Com dll is having an exposed function like
CAN_Write([in]long ID,[in] long DLC, [in,size_is(DLC) unsigned char* Data,[out,retval]long *pRetStat);
But when i am calling this function using automation invoke node in labview the Data is not a pointer reference its just accepting unsigned char Data . Can you please let me know how shall i pass the data to this array?? Or shall i need to change my DLL function...
Thanks in Advance.

  • Labview 6.0 cannot call ActiveX functions after upgrading to Teststand 2

    I'm running on Win2K on my development system. I have been running fine with Teststand ver 1.0.3 and Labview 6.0 with several VI's using ActiveX to work with the TestStand engine. I tried installing TestStand 2.0 (dated Aug 2001) next to 1.03 (not on top of it) to start upgrading and all those ActiveX VI's no longer functioned.
    NI's documentation says Teststand 2 installs the LV RTE 6.02 on the system and to run a "REPAIR" on the LV RT Server 6.02 if installing LV 6.0 after Teststand (not my case). I ran the "repair" anyway to no avail.
    I tried running NI's ActiveX example "Write Table to XL.vi" and it also does not run (Error -2147024891, "Access is denied.
    in Open Excel and Make Visible.vi->Wr
    ite Table to XL.vi"). I have run this before just fine.
    I've even tried re-installing LV 6.0 and re-running the repair to no avail, also mass compiling everything in site. Always the same error!
    Please help, anyone. My system is DOWN!.....

    We have not seen this exact problem before with TestStand 1.0.3, 2.0, and LabVIEW 6.0. If your system is still down, please give us a call and we can talk through getting everything working. You can make a phone support request online by going to Request Support and choosing "Phone NI" from the Communication Method Pull Down menu.

  • How do I call Vee functions from TestStand ?

    I wish to call Vee functions from TestStand steps.
    I am using Vee 6.01 and TestStand 2.0.

    Hi Gerry,
    Sorry about that. Below is a sequence file created in 2.0.1f1. Please copy the contents of the zip file (previous attachment) into the folder \Examples\VEE\Using ActiveX (VEE 6.0). Please create this directory if it does not exist. The next thing you will need to do, is register the TestStand VEE server located in \Examples\VEE\Using ActiveX (VEE 6.0)\VEE_StepType.dll. To do this:
    1) Select Start>>Run.
    2) Type regsvr32 "C:\TestStand\Examples\VEE\Using ActiveX (VEE 6.0)\VEE_StepType.dll"
    You should get a message saying that the registration was successful. You should now be able to run the example. Please let me know if you encounter any further problems. Thanks!

  • Call ActiveX from Java? (not Runtime.exec())

    The Java ActiveX Bridge allows access from Visual Basic to Java components. Is it also possible to communicate the other way round, i.e. calling ActiveX components (DLLs ...) from within Java? (Perhaps via JNDI?)

    Thanks but i don't look for a 3rd party library (and of course not one that was last changed in 2001 ...). I'm playing around with System.loadLibrary() that seems to work, but when calling a function from this DLL, i just get
    java.lang.UnsatisfiedLinkError: ComputeValuewith ComputeValue being the following visual basic DLL:
    Public Function ComputeValue(value As String) As String
        ComputeValue = ">>" & value & "<<"
    End Function

  • Passing Variant to dll using call library function node

    Hi,
    Using LV2012
    I have a dll that the following prototype:
    SetTestResult(LPCTSTR Serial, int Test, int Result, VARIANT measuredValue);
    How can I pass the Variant to this node when my variant can be either int or float.
    I have tried "ToVariant" function but it is not sending data and gets error 1517 on LabView. For configuration parameters for variant I have used ActiveX type and datatype as activeX Variant Pointer.
    So for call library function node my prototype looks like this:
    int32_t SetTestResult(CStr Serial, int32_t Test, int32_t Result, VARIANT  *measuredValue);
    Can someone help me understanding What am I doing wrong here please?
    Thank you,
    Hiren
    Hiren Patel

    Hello Hiren,
    Posting your code (even without the DLL) would definitely make it easier for people to point out potential issues.  Here is an example that demonstrates passing an ActiveX variant to a DLL built in CVI, I would suggest cross-checking the way the Call Library Function Node has been configured.
    Example:Transferring an ActiveX Reference Pointer to a CVI DLL

  • How call Flash function from C++?

    Communication between C++ and ActiveX Flash object is
    adjusted. The ActiveX calls C++ functions. But how a call Flash
    functions from C++?
    I try so: v_flash is control variable of the ActiveX the
    container.
    A code: v_flash. CallFunction ("test");
    No effect
    How it to make?

    Hi David, Thanks for the response. I found this solution by
    following method:
    Flash code either in class or frame:
    ExternalInterface.addCallback("sendTextToFlash",
    getTextFromJavaScript);
    public function getTextFromJavaScript(user):void {
    trace(user);
    //Now whenever JavaScript function will be called from any
    HTML or back end language then it definetly call directly that
    flash function by following method
    //HTML Code
    function sendData(user){
    //alert("values coming "+user);
    SendDataToFlashMovie(user);
    function getFlashMovieObject(movieName){
    if (window.document[movieName]){
    return window.document[movieName];
    if (navigator.appName.indexOf("Microsoft Internet")==-1){
    if (document.embeds && document.embeds[movieName])
    return document.embeds[movieName];
    else {// if (navigator.appName.indexOf("Microsoft
    Internet")!=-1) {
    return document.getElementById(movieName);
    function SendDataToFlashMovie(user) {
    var flashMovie=getFlashMovieObject("myFLA");
    flashMovie.sendTextToFlash(user);
    Now HTML or back end language has just need to call
    sendData(
    value)
    I think its the right way, but if there is any other short
    method like just call the function name from HTML and that directly
    respond to Flash as per function name, then please let me
    know.

  • CNTL_ERROR while calling a function module from Java webdynpro

    I am calling a RFC function module from javawebdynpro app
    which inturn calls a function module performing BDC on CAPP transaction. When I run this from SE37 of the same system or a different system everything works fine. But when called from Java webdynpro app, it raises a CNTL_ERROR exception and creates a short dump.
    Any help on this is highly appreciated

    Good catch, BI Learner. This was exactly it: when assigning the values from SOURCEFIELDS directly to the import/export parameters, you have to make sure that the types are EXACTLY the same, otherwise it will not work (the routine stops with an error when calling the FM, but there is no dump).
    Therefore, to solve my problem, I created the declarations precisely as expected by the FM and assigned the values to these fields:
    DATA:
          SOURCEVAL TYPE  /BIC/OIINVQTY,
          SOURCEUOM TYPE  /BIC/OIUSUOM,
          USITM TYPE  /BIC/OIUSITM,
          TARGETUOM TYPE  /BIC/OIUSUOM,
          CONVERTED_COST TYPE  /BIC/OIINVQTY.
    DATA PRODUCTION_UOM TYPE /BIC/OIUSUOM.
    " get the Production UOM
        SELECT SINGLE I~/BIC/USPRDUOM
          FROM /BIC/PUSITM AS I
          INTO PRODUCTION_UOM
          WHERE I~/BIC/USITM = SOURCE_FIELDS-/BIC/USITM AND I~OBJVERS = 'A'.
        IF ( SY-SUBRC = 4 ). " no records found
          "RAISE PARTNO_NOT_FOUND.
          RAISE EXCEPTION TYPE CX_RSROUT_SKIP_RECORD.
        ENDIF.
    " load the parameters
        SOURCEVAL = SOURCE_FIELDS-/BIC/USFRZMFC.
        SOURCEUOM = SOURCE_FIELDS-BASE_UOM.
        USITM = SOURCE_FIELDS-/BIC/USITM.
    " then you can call the FM
        CALL FUNCTION 'Z_CA_CONVERT_US_COST'
          EXPORTING
            PSOURCEVAL                = SOURCEVAL
            PSOURCEUOM                = SOURCEUOM
            PUSITM                    = USITM
            PTARGETUOM                = PRODUCTION_UOM

  • Can we call a function module in ADHOC query

    Hi
    Can we call a function module in ADHOC query if yes how.
    Also we ned to know how to call a function module in SAP query.
    An early responce is appreciated.
    Thanks and best regards
    Rajeev

    Okay as far as I understand your aim is:
    To fill a field in the output list with a value that is based on the current line information and calculated by a function module
    So go to SQ02 and create an additional field in the InfoSet.
    You can refer in the coding to the technical names you can see in the left tree window like P0000-PERNR.
    More information is avaiable in the Help part look for additional field in SQ02.

  • /How to call a function in another PowerShell script

    Hi All,
    I want to use dot-sourced method to call the function from other script,While calling Function.ps1 from the second script there is a Null value in the beginning,
    How can we ignore this null value or there is a better approach of doing it without using Import-Module.
    #=======Function.ps1============
    function add($x,$y)
    $z=$x+$y
    Write-Host "The value is $Z"
    add $a $b
    #===========End==================
    The second script which has been dot-source to call the function
    #================Main script==========
    . C:\Users\Anirban\Desktop\Tester.ps1 |Out-Null
    add 1 2
    #================================
    Regards,
    Anirban Singha

    Dot Sourcing is adding the function ADD to console environment and the script is acting like a module vs a script with parameters.
    The Add $a $b line should be removed. (Where are $a and $b defined?)
    They are not defined hence, "The Value is " blank line
    #=======Function.ps1============
    function add($x,$y)
    $z=$x+$y
    Write-Host "The value is $Z"
    add $a $b
    Should be
    #=======Function.ps1============
    function add($x,$y)
    $z=$x+$y
    Write-Host "The value is $Z"
    PS C:\Test> . c:\tester.ps1
    Add 1 2
    Add 3 4
    The value is 3
    The value is 7
    However the add can work without dot sourcing the script file by parameterizing the script
    #=======Function.ps1============
    Param ($a,$b) # Parameters to the script
    function add($x,$y)
    $z=$x+$y
    Write-Host "The value is $Z"
    Add $a $b # body of script
    PS C:\Test> 
    C:\Tester.ps1 1 2
    C:\Tester.ps1 3 4
    The value is 3
    The value is 7

  • How to call a C pointer from call library function node

    I have a client/server application which the client I am trying to develop using Labview.  When I use to communicate the server and the client using the program provided by the manufacter, the system works perfectly.
    Now, I am trying to develop a system using labview, because I need to get another things.
    I have the DLL provided by the manufacter and the .h too, so I can check the functions parameters. One of these functions needs to be called using a struct element. Probably, the function's DLL instantiates the elements of this struct.  I use the call library function node to do it.
    When I receive the data, the function returns to me the struct that I passed as a parameter before, and then I can read all the elements of the struct, except the string element that returns nothing. The struct elements that are numerical, I can read them perfectly.
    Another thing that is important to say, is that the string data was not returned in fact by the DLL function that the system calls. I have to pass a pointer (I use it as unsigned 16 in Labview, but I tried before as string and unsigned 8) as a parameter, and this pointer will point to the memory location that the string is. When I try to read what is returned by the function, I can read nothing. The same function returns that the size of data that is returning is 17 bytes.
    How can I solve it?
    Thank you in advance

    Did you take a look at the example that ships with LabVIEW that shows how to do all sorts of data passing to DLLs. I believe your situation is one of the examples listed. You can find the example VI in the "<LabVIEW install directory>\examples\dll\data passing" directory.

  • Program making a RFC call to Function Module not working in background

    Hi All,
    I have an ABAP Program which is used to do a reconciliation check between the R/3 and BI system for Invoice Data. Please find below the details of the program flow:
    1.     Program counts the number of records in the DSO table and aggregates the Net_Value based on the date range (passed as parameters)
    2.     Program calls a Function Module (RFC Call) which counts the number of records in the R/3 table and aggregates the Net_Value for the same date range
    3.     Function Module Passes back the count values and aggregated Net_Value to the program
    4.     Program compares the count and aggregated Net_Value from EDWH and MSP systems and sends an email mentioning whether the counts match or not
    However we are facing an issue.
    Whenever, we execute the program in dialog mode, it works fine and fetches results within 5-6 minutes. However if we schedule the program to run in background (parameters through a variant), it gives no results even after running for over 3-4 hours. We tried figuring it out yesterday but could not come to any conclusion. Since there is a RFC call being to the function module, we were wondering if we need to specify some other parameter as well.
    Thanks & Regards
    Dharmendra

    RFC Call is a procedure for executing remote enables function modules. It is done via the 'Remote Enabled' radio button on the function module's attribute screen.

  • Passing arrays with Call Library Function does not work after application builder

    Calling a DLL with Call Library Function which requires an array of data works correctly in Labview, but after building an exe with application builder, the call no longer works.  Dereferecing the pointer in the DLL retuns all 0s and not the actual values.
    Solved!

    I did not run your code because it is a little unclear to me what it does.
    Two things:
    First, is the DLL you are calling the DLL-ified version of PopUpNames.vi? Then the problem is likely that the panel is not being built into the DLL.
    When LabView builds an application / dll, it strips the front panel and block diagram from all VIs that it doesn't think need to show a panel at run time. This reduces file size and increases code security. The App Builder's panel inclusion logic can be overridden by Build Specifications -> Source File Settings -> Remove front panel. A better method is to put a property node on a control in a window you want to show marking it "visible"; this is sufficient to tell the App Builder it should keep the panel.
    Currently Source File Settings shows "no dependencies" (clearly incorrect---another evil side effect of Express VIs I guess) but if you change the settings as shown below to keep ALL panels, one might hope the App Builder can figure it to keep the panel when it deconstructs the Express VI. (Alternatively convert the Express VI into a regular one.)
    A second comment: I am a bit flummoxed at the larger goal here. You are calling LabView DLL from LabView, which doesn't make a lot of sense, so I assume your larger goal is to call LabView from C or vice-versa. In that case be aware that your DLL is x86 (32-bit) but you are passing 64-bit ints as your pointers. In this case it is 32-bit LabView with 32-bit pointers in embedeed in 64-bit containers calling 32-bit LabView with 32-bit pointers in embedeed in 64-bit containers, so it all works, but if your going to call this from C or whatnot you're going to have to follow that same design.
    When calling C code the LabView Call Library Function does have a "unsigned pointer-sized integer" data type that always appears to be 64 bits in the dev env but which actually passes a 64 or 32-bit int to the DLL depending on the environment. The "pointer sized int" has to be 64 bits in the "LabView" part of the code because LabView's strong typing requires the data type to be determined at compile time. Casting all pointers to the largest data type in LabView makes it possible to write platform-independent code, but down at the Call Library level you still have to put the right number of bytes on the stack.
