How to programmatically modify PassFail DataSource

[Romuald123]

Hello,

I add programmatically a PassFail Step to a TestStand sequence (4.0), but I don’t find the way to modify programmatically the parameters 'DataSource'.

If someone can help me, by advance thank you.

Step.DataSource = False  or Step.DataSource = True.  Put this in the pre or post expression.

Is there something specifically that you want to set it to?

I’m a beginner with testStand, maybe I 'm not in the good way.

I parse a file with testStand for create a new testStand sequence. I add to the new sequence a new step for compare the read value to an expected value.

I don’t find the way to programmatically modify DataSource, I would like to add for example: “Step.Result.PassFail=(Locals.readValue==Locals.ExpectedValue)”

I hope, my explanations are clear.

You will most likely need to set it using the API.  Something like this:

Locals.PassFailStepReference.AsPropertyObject.SetValBoolean("Result.PassFail", 0, Evaluate(Locals.readValue == Locals.ExpectedValue))

Or just set your DataSource:

Locals.PassFailStepReference.AsPropertyObject.SetValBoolean("DataSource", 0, "Locals.readValue == Locals.ExpectedValue")

the second option might be a better option.

Hello,

It works with SelValString.

Thank you for your help 🙂
