Notifying the end of an Asynchronous call

[Jeremie_technion · Accepted solution]

Thank you for all your answers.

I expressed myself wrongly, I am not trying to just wait and do nothing, otherwise indeed a simple subVI would have been enough.

But I want that as soon as my subVI is executed, the state changes.

I managed to do that in a simpler way:

I defined a boolean in the main VI as wrong, indicating that the subVI has not been executed yet or that its execution has not ended.

I put my "wait for asynchronous call" in a flat sequence, followed, farther in time, by an assigning "true" to my boolean, which occurs when the subVI is executed.

Best,

Jeremie

Well, I'm glad you are satisfied that you have a "solution" to your problem.  Sadly, I doubt that anyone reading this thread is going to learn much from it, in particular they will be hard-pressed to understand the problem and to understand your solution.

One thing seems pretty clear -- the only person who had any understanding of your code was you, yourself, because you never presented your code to us, nor was there ever a clear description of your State Machine and the role of the asynchronous VI as it interacted with the SM and its various States.  I'm reasonably sure that I would not choose whatever you did (that involved a flat sequence around a Wait On Asynchronous Call, followed by setting a Boolean to True) -- it just doesn't make sense to me, but then neither did the question you posed.  Oh, well, an opportunity missed ...
