  1. Hi all, I'm somewhat new to Labview so excuse any ineptitude that may arise. I have a program that is centered around an array of Devices - they are various different object types that descend from an abstract Device class. I'm trying to make a VI that can call the correct method VI for a given device in this main list (in an object oriented way, of course). So far this has been fine for most VIs, but now I'm trying to make an overridden VI in each class that opens when called, like a dialog box. As of right now, calling the "Display Info.vi" (the VI in question) on a given device opens the Display Info VI from the Device class, which is basically just a blank, unimplemented VI and therefore useless. Are there some settings I need to check to enforce polymorphic behavior on this VI? Thank you for any info you can provide!
