Remove programatically a substep

[YR42]

Hello,

I'm trying to customize a Type.ini file in TestStand (4.0) with LabVIEW (8.5). I'd like adding/removing a substep to each created step type.

The method 'AddSubStep' is OK, my type.ini is updated.

But, before creating a new substep, i'd like removing all previous but an error is generated:

"Error -17331 occurred at Item is locked, protected, or in use and cannot be deleted."

I don't find a solution to remove the protection. Why can i add a new substep and can't remove it after?

thank you for your responses

Hi,

I advise you to read this: NI TestStand Type Management Best Practices

What API are you using to remove the substeps?

YR42,

There appears to be an issue with the RemoveSubstep() method of the API. As a workaround you can use the following expression or equivalent API calls instead:

Locals.StepTypeReference.AsPropertyObject.GetPropertyObject("Substeps", 0).DeleteElements(0, 1, PropOption_OverrideNotDeletable)

We will look into this issue with the StepType.RemoveSubstep() method. Thank you for bringing this to our attention. Also, you might still want to read the document Aurelien posted a link to if you haven't already as it might contain information that is helpful to you.

Hope this helps,

-Doug

Hello,

Yes doug your workaround works fine.

YR42  in attachment you can find an example with 2 methods.
1) The expression
2) Active-X steps   (this will be helpfull using Labview).
