Call subvi from exe

[FabioBone]

Hi,

I call an exe with system exec block. I build that exe with Labview application builder. I need  to open the front panel of some sub-vi included and I need to close them when they finish. The sub-vi node setup is configuered in this way: show front panel when called; close afterwards if originally closed. At the very first time I didn't include those sub-vi in source file tab of the application builder, so the application opened a pop-up of error. Then I include them in the source file tab: now the program works, but the VIs are all opened when the application start. I don't like that. How could I reply exactly the behaviour of VI in the exe file?

Thanks

Use property nodes within the subVI itself to open and close it's front panel.

Hello Mark,

Is it possible to close front panel of subvi from main VI??

Sure it is.  You just have to get a reference to the VI and use an invoke node to close the front panel.

It's even better to use Invoke nodes. 😉

Its Great,

One more thing I am looking for is to get list of all subvis which are in memory. How do I do this ??

If you drop an empty property node it's linked to Application by default, look for Application - Exported VI's in memory, or something similar.

My mistake in previous post actually I looking for list of subVIs having front panel opened. I should not have asked every small things but I am really not finding a way to get a list of opened sub vis. I would heartly appreciate if you could post a code or image for the same.

That's a valid question, as it's not that simple. 🙂

You'll need to get the Application in memory list, loop through it and open all ref's (as shown above) and check their window property.
