Set Post Expression of Step (Not Next or Previous Step)

[christopherdean]

Is it possible to set the post expression of a step, which is not the Next or Previous step?  

I know this is possible

RunState.NextStep.PostExpression = "Enter Post Expression Here"

 I am looking for something like

RunState.Step("StepID").PostExpression = "Enter Post Expression Here"

Does anyone know if there's a way to accomplish something to that effect?

Thanks!

RunState.Sequence.GetStepByUniqueId("ID").PostExpression = "Blah"

Hope this helps,

Thank You! 

I didn't realize I should be looking in RunState.Sequence

I think I'm going to use GetStepByName now that I know that exists, and I can paramterize that to be an intuitive control.

If you plan on executing the sequence in multiple threads at once, it's best not to make a self-modifying sequence like this since many of the step setting properties like PostExpression are shared between all threads.

Doug,

Thanks for the heads up.

The step will only change once, at the start of the routine, if at all.  I am only interested in setting up the elements of an array which I write to my datalog, which does not change very often, and will not change once the routine is running.
