A VI opens when executing, even if I don't want to

[LabViaw 6.0.2]
Hello everybody,

I've got a problem with Labview:
When I build a VI dedicated to be a interface Window, I configure it to
open when executing, in the VI properties.
But sometimes I change my mind, and I don't want the front-face to open any
more. So I try to change the configuration, but it never works : it keeps
opening at execution.
What should I do? Is it a bug? The only solution i found is to copy the
diagram in a new VI, and save this last one over the first one.

Thanks in advance,
Pierre Chatelier

hi
I tried duplicate your problem in LV 6i, and I do not see this problem.

Have you tried swithing between Dialog/ Default for VI's Window Appearance property?

Is this good news ? ...depends upon point of view! 😉

Oh, yes, I did! Since it did not work, I eventually chosed to the custom
appearance, and uncheked the boxes like "Window with title" that seemed
linked to the window's rising. (sorry if this label does not match, but
I use a french version, so I must try to translate...)

Actually, under the Window Appearance properties you have to make sure are not selected:

Show Front Panel When Called
Show Front Panel When Loaded

Make sure both of them are not selected and your problem will go away...

I surely did! It's one of the first thing I tried, but it does not work.

Pierre,

There are two ways to do what you are trying to do. The first is the Window Appearance setting in VI Properties. The second is if you right-click on the subVI itself, you will see an option for SubVI Node Setup. Make sure that the VI is not being shown from these options as well (Open Front Panel Wehn Loaded, When Called, Close If Originally Closed, and so forth). The difference between these methods as that the VI Property settings are for every instance of that VI. The SubVI Node Setup is for just that one instance.
