How are you calling the LabVIEW DLL from the command line? A DLL is just a library of code so it can't be called directly (unless there's something I'm missing? I thought you could only run executables from the command line?

It is possible to pass command line arguments to a LabVIEW Executable by ticking the 'pass all command line arguments to application' option in the build specification and you can then access them using the Application property Command Line Arguments which returns an array of arguments - there's some information on that here: https://decibel.ni.com/content/docs/DOC-10281

Hi Sam,

Thanks  for the reply

I tried  calling Labview excutable from command line  and passing argument s through command line. It was succesful.

But  I have requirement where I have  ot call  labview dlls from  a third party software  which only supports  command line scripting.

I want  to make sure  whether it is  possible  to  call  LabviewDLL from command line . Other  wise  i have  go with the executables

No, it is not possible. As I said, a DLL is a compiled library of functions - it cannot execute on it's own. You can call the functions in that DLL from any programming language by using the appropriate include/function calls (from the header file that gives you the function prototypes). This isn't just true for LabVIEW - it's the same for any other DLL.

You will need to either call the functions from the DLL in your other software, or write a LabVIEW executable which takes in the command-line arguments and runs the appropriate functions. This executable could even call the LabVIEW DLL you have produced!
