Scripting API Create Parameter Pass by reference

[TeamJP66]

Hello everyone,

As part of a teststand sequence generation tool linked to DQMH modules, I am trying in vain to create a sequence parameter with the attribute "Pass by Reference" and not "Pass by value" via the TestStand API in LabVIEW.

Result:

Wish without manual intervention:

Thank you in advance for your help.

Your code is setting the actual value of the parameter.

Choosing between byRef / byVal option for the parameter has to be done upon creation of the parameter. I don't think SetValString is the appropriate way to do so (though I can't tell you which one to use, I have to admit)

Need to correct myself after checking the documentation! I would've expected to have a "proper/ dedicated" Method for creating parameters, but there isn't

From what I have learned, the switch from byVal to byRef is achieved using a property flag for the parameter

Can you try to do the following: 

ParameterRef.AsPropertyObject.SetFlags("Pass by Reference", 0, 0x4)

Hello Oli_Wachno,

Thank you for your return and your research, indeed it exactly meets the need and works!

I hadn't thought of being able to find this property in the flags 🙂
