How to stop/abort a subvi called by reference ?

[billko]

It may as well be the same subject, because you should never - if at all possible - accept a solution that you don't understand, because if something breaks because of it (or it might break itself one day), you won't know how to fix it.

I completely agree with you but there are two issues in one here ;). The solution I accepted for the first issue is working, but an other issue different appears, I will create for sure another post for it if I do not find any solutions in existed ones!

Wasn't able to open your VI cus its newer than my version.

Give you an example. If your subVI currently has a stop button that is refreshed (read) in a loop say.

Wire up a property node in your TopVI with the subVI reference and the subVI stop button. I use the Invoke CtrlValSet in the pic below.

You could use a Global boolean in your code and have the subVI read the global like what was mention already. This would make every VI reading the global stop.

There are many other ways, too numerous to list here.
