Displaying front panel

[MarkBai]

Hello,

Is there a way to display a control icon on the front panel of a sub VI to the front panel of the main VI?

Thanks

Assuming you have wired the desired control on sub vi front panel using connector block, just right click at the sub vi input and create control.

Another option, if you want the control to be updated on the main vi's FP whilst the sub-vi is still running, is to use a subpanel. If you go into the example finder and search "subpanels", you will find a few good examples of how to use them.
