Hello,I am trying to run a code where I have a "Main VI" with a header and a SubPanel. As I change the value of the Selector into the header, the SubPanel should show a SubVI. Into the SubVI I have buttons that will generate random numbers for the Indicator 1 (SubVI 1) and for Indicator 2 (SubVI 2). The idea is, as I push the button for random number generation, the Indicator will be updated even if the SubVI currently showed into the SubPanel of the Main VI is not the one that contains the indicator that will get the new random number.I created references cluster (strict type def) to make things easier. Find attached a zip file. Uncompress all files to one single folder and run Initialization VI.vi file. An error message (1001 - Front Panel is not open) will pop up and Main VI.vi don't open, as it was to supposed to.I changed "Windows appearance" to Default, Dialog, etc. and tried almost everything but I am not getting the expected result. Of course this code is just an example to show what I want to achieve, that's why it is so simple.Thanks all.Dan07.

Do you definitely need that structure? Normally I would expect Main to be the top-level VI, and Initialization to be a subVI. If you're not restricted to that particular VI structure, perhaps you could instead describe the effect that you want to achieve and let others suggest how you might accomplish it, instead of describing the implementation you want. For example, in your current structure you know how many possible subVIs you might embed in the subpanel. Given that, it might be easier to place a tab control on the Main front panel and hide the tab selectors. Assign one page to each subVI - either embed one subVI in each page, or set up the controls for each page that correspond to the ones needed by that subVI. Use the enumeration as the tab selector.

Open subvi into subpanel and handle events

Solved!

Or maybe the path is incorrect and there's no VI there. You'll never know as you ditch the error.

Use a Static VI ref so see if it works.
