project explorer multiple vi's open

[mikie121]

Hi.

I have a strange problem where if I open a VI from the project window another VI opens too.

How do I stop that from happening?

The hierarchy shows that the 2nd VI is below the first.

Thanks

Find that subVI on your mainVI's block diagram.

Right click.  SubVI Node setup.  See if you have the option Open Front Panel when Loaded checked.  If so, uncheck it.

That setting could also be in the VI Properties dialog of the subVI that is opening up where "Show front panel when loaded" is checked.

I would look at this first.  It is under Windows Appearance then Customize.

But I need that VI to show its front panel when I run the program.

The problem is that the second VI opens when I open the first VI WITHOUT running anything, ie in EDIT mode. I have never seen this before and a PC restart doesn't fix it.

To be clear here are the steps that result in the problem:

1. Open my project file. This shows a list of about 20 VIs

2. Double click on the first VI (my main VI) and two VIs open, the one I want and another VI that's about 6 VIs down the list.

Mikkie,

you are confused of  "Open front panel when loaded" and "show front panel when called"

In SubVI Node setup. 

If you enable the option "Open Front Panel when Loaded" , it will make that sub vi opens when you open the main vi.

If you enable the option "Show Front Panel when Called" , it will make that sub vi opens when the time of execution.

So Pls do as Ravens Fan said.
