Change front panel objects properties of a closed VI from another VI

[zagarro]

Hello! I'd like to change strings of a menu ring in a front panel closed VI from another VI that is opened...anyone can help me?
I attached the VIs, but this example works only if the target VI's front panel is opened.

Thanx a lot, bye Stefano

Hi,
you should use the method Save Instrument after you change the default values. The problem is that you can't use it on an existing vi when you have opened a reference on, it returns an error.
A workaround is to move first the vi to a temporary location, open a reference on it, change its default values and save it to the target destination. You don't need to open the front panel.
See attached image for saving vi.
Good luck,
Alberto

Thanks a lot for your help Alberto, i thought to the same solution but i'd like to solve the problem without using temporary files....if it could be possible.....

It is possible: Open untitled2.vi and change the ring menu items of untitled.vi (both need to be in the same directory in the example)

Amazing! I didn't try that way.
Forget all what I said above!
Thanks for sharing,
