Hello all,

I need your help to understand how to connect a GUI with main loop in the parent VI. Please think in the following situation. I have a main VI which calls asynchronously a subVI containing the GUI, which basically it have to send commands and parameters back to the main loop. The only way I know to send back data is by using in the main loop an invoke node configured to get/set the value of a control in the GUI control panel. But... what if I want to send data which is not in a control or indicator, but it is the result of a calculation/decision (such a command), there is a way to return data which is not shown in the GUI?? (without adding a hidden control in the front panel...)

I have spend quite a lot of time browsing for the solution, but I think I'm not using the correct keywords because now I'm more confused that at the beginning.

thanks!

felipe.-
