How to get parameter information on DLL function call (CVI) in TestStand?

Hi,
 I wrote a simple Instrument Driver in CVI, and it has 3 parameters Voltage, Current, Channel.
I made a DLL in order to call this function in TestStand as an action.
That works fine, the only problem I have is that it shows my function as DC_Conf (arg1, arg2, arg 3) and I only get the type information like double double int.
I do not get the parameter names Voltage, Current, Channel...
How can I get this information to be displayed in TestStand so I know which parameter arg 1-3 is Voltage,Current,Channel in case I forgot?
or 
Is there a way to display the help text of the driver in TestStand?
I tried clicking on the (?) button next to the function call but it did not do anything...
My TestStand is version 4.1
Thanks...Ness

Ness,
When TestStand populates the parameter information, it does so by looking at the dll's type library.  CVI automatically creates a type library for a dll based on the function's signature, which can include the parameter names.  However, if the function prototype does not contain variable names, then CVI cannot include names in the type library.
You can define your own type library to directly control the information available to TestStand from your dll.  If you want to define your own type library, you can do so using a .fp file.  This will allow you to use complex data types (such as structs), and to rename your parameters.
Here's a KnowlegeBase describing the process: Embedding Type Libraries in a LabWindows/CVI DLL for use in TestStand
Either solution proposed here will work, and they each have tradeoffs:
You can definte the variable names in the function prototype.  This keeps the functions self-documenting, and is the easiest solution.
You can create a .fp file and define your own type library.  This allows you the most control over exactly what you will see in TestStand, but requires you to create a new file, and to keep that new file up to date if you make any changes to your source code.

  • How to get transaction id of a function called in background

    Hi all,
    does someone know how to retrieve t-id of a function called in background (tRFC) client side? I found
    'ARFC_GET_RECEIVER_TID'
    'ARFC_GET_TID'
    but these works server side (function called knows its t-id .. caller no). Is there some similiar client side so that after calling function I can retrieve its transaction id ? I know it's not the same context, for explaining better, what I need it's something like fork() in C, where process father (the one that forks) receive as return value process id of process forked.
    SEARCHING ON FORUM I see that many people answered on question about transaction id with sy-tcode misunderstanding the question. This transaction id it's not the tcode. This is the char 32 unique transaction code
    thank you
    regards
    Gabriele

    You can have a look at function TRFC_RECEIVER_INFO

  • How to get more information regarding a service call

    So are all of your services working now?

    Here are the gory details. This is how I described the problem when I called for service: 'I am a u-verse customer. I have TV, internet and phone. There was an outage of all services for 15 hours. Voice and TV returned. But not my broadband internet connection.'  Tech arrived. Used his i-pad and says internet is 'working'. I tell him my computer, tablet, etc etc will not connect. He says he is writing down that internet works. My devices not his concern he says. Well OK I say forget my devices but I want ALL the TV channels that are part of my u-verse package to work before you leave. He says 'but TV is working'. I say no, this is not true unless ALL the channels I pay for are working, --please check this channel (interactive Country Deep--530 in my channel lineup). He says oh that channel is probably not part of your package. Excuse me I say. I pay over $200 a month for my services and U300 is my package and it most certainly includes the Country Deep channel which is not working (it is spinning, spinning) and which I do watch. I know from the user perspective that there is a difference between the Country Deep channel which loads data before it plays and the 'normal' channels. He looks at me like I have two heads. However I felt quite certain that if he took care of the problem with that interactive channel then I would be able to get all my devices to work. He threatened to depart because I was not listening to him. However he was not listening to me either. He would not 'own' that there was any u-verse problem. Since this did not make sense to me and I had already invested at least eight hours of my life attempting to get help I was frustrated and I will certainly confess to not 'listening' to him very well. Unfortunately I then had to leave and go to work. He left no information about what was done and no information with the person I left in charge but it took over 4 hours and apparently a number phone calls to other people. And I do know he swapped out my DVR because I lost all recordings but that is all I know. I tried to look online at the workorder but no further information was available.

  • How to pass Visa Resoure Name parameter to labview dll in labwindows​​/cvi

    Hi, everyone
    I build a dll from labview, the prototype is : double  getchannelpower(double f, uintptr_t *VISAResourceName);
    I don't know how to pass VISAResourceName to this function.How can I get the VISAResourceName of this type(uintptr_t *)?
    Is it related to the paremeter ViPSession in function viOpen(ViSession sesn,ViRsrc rn,ViAccessMode am,ViUInt32 ti,ViPSession vi)?
    BRs,
    lotusky

    1. uintptr_t *VISAResourceName in the labview dll is connected to viOpen function as input parameter internally.
    2.I can call the labview dll in labview via CLF Node, when the VISAResourceName parameter is set  to Numeric(32-bit int or 32-bit usigned int) OR Adapt to data(Handle by Value). And I got the value of the VISAResourceName parameter, which is 0; When I directly connect 0 to the dll, it still works. But in labwindows, when  I pass 0 to the VISAResourceName parameter of the dll function, I got a FATAL RUN-TIME ERROR: The program has caused a 'General Protection' fault.
    mkossmann 已写：
    Could you check what exactly uintptr_t *VISAResourceName in your labview dll does.Might it be that it is connected to the labviews Dll internal ViOpen() ViSession output parameter ?.   And the name VISAResourceName is misleading.
    Another idea would be that Labview uses 32bit Unicode for the ResourceName. And you have to convert the C String to that Unicode first.

  • How to get parameter value from report in event of value-request?

    Hi everyone,

  • Question on the parameter type of DLL functions

    Question on the parameter type of DLL functions
    I am trying to develop an interface to control a laser with LV8.2  I am planing to use the VI “Call Library Function Node” to call the DLL and set the exact same parameters of functions in the DLL.
    According to the DLL manual of the laser, there are six functions.  One of the prototypes is:  function getstatuspointer : pointer. I don't know how to set this parameter for the function. Is there anyone who can give some hints? Thanks!
    BTW :The following is a description of the function:
    This function returns a 32 bit pointer to the STATUS data structure (Tstatusrec). In the 32 bit DLL, every application is using its own copy of the data structure (local
    memory). The data structure is a packed structure. "packed" means that the fields in the structure are not aligned on word or double-word boundaries.
    Tstatusrec = packed record
                            size : word;
                            initstat : byte;
                            queuefill : byte;
                            anzapp16 : word; (not used)

  • How to get sysnr value in a Function Module

    Hi all,
    I need to get the sysnr(system number) value of the R/3 system. I execute a RFC function module and need to get the value of sysnr of the system it executes in as a return parameter. Can somebody tell me how to get this value in the function module and return it.
    Thanks and Regards,
    Pratik

    Hello Pratik
    The system number has to be defined in the RFC destination. Thus, select on your local system (where you call the RFC function module) the corresponding RFC destination from table <b>RFCDES</b>. In field RFCDES-RFCOPTIONS you will find a string like this:
    H=<ip address>,S=21,R=N, ...
    S=system number

    You might profit from a visit to a Minneapolis Apple store. With a brand new Mac, I think they will be most helpful - not just with transferring files, but with other advice as well. And I strongly recommend you invest in a back up drive. The Apple folk can help with that as well.
