title: Updating a LabVIEW GUI from a subVI
body: <p>I'm writing a program to control two similar devices in Labview. In order to avoid copying the code I use subVIs. But I have a piece of code where I update some values on the GUI  inside a while loop. I'd like to know if it is possible to somehow have this loop inside my subVI and have the subVI sending one  of the output parameters after each iteration.</p>
