Hi all, In the efforts to Have a clean data wire in my app I am suing a data wire such as this: I Have a VI that reads and gets and reset the data on the wire and am using the RefNum for manipulating or storing the data on the wire meaning I only have a reference wire passed through my multiple loops. To get variant and translate it into my data I decided to use a polymorphic VI and use the type as a data type selector for my convertor: Is this proper or there is better or more efficient way? Cheers, M

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!
