how to close open subvi's in the beginning of running the main vi.

[noxus]

Hello,

I've got a pretty large application that is dependant on several subvi's.

I'm searching for a way to close the subvi's when I start running my main application.

All these subvi's need to be closed during the initialisation phase of my main application. (before it is doing its main task.)

I know it is possible to ask for the VI's in memory for my LabVIEW application, but I don't know how to close a subvi programmatically. (unload it from memory)

What I want to do is check for a list of open subvi's in the beginning of my main application. (only a limited set of subvi's)

If one of the subvi's is indeed open I want to close it (unload it) and then start doing my thing from within the main application.

Note: The subvi's need to be closed so that I can load them dynamically later in the program. If one of the subvi's is open and I start running my main application I get an incorrect behaviour.

Thx for the help!

Noxus,

I programmed a small example.
If you have further questions do not hesitate to come back...

(Additonally I added the screenshot in term of that you do not have LV 8.20)

Thanks ThSa,

This worked fine for me.

I first check to see if the FP is open and only close it when it was already open.

Thx again!

Just don't forget -- it's considered good practice to close any vi references you open...

Kevin,
you are absolutely right, but that should be only a demonstration and not the final solution 🙂

I know, and it's also implemented like this in my final application!
