the_mitten 1 Report post Posted August 6, 2018 Has anyone found any properties or methods associated with malleable VIs? Specifically, I was hoping to find a way to invoke the "Convert Instance VI to Standard VI" function after confirming that a selected VI was indeed malleable. LabVIEW reports the class type of a selected malleable VI on the block diagram as a standard Sub VI, and I didn't see any properties/methods under the VI class. I'm exploring what it would look like to make a utility to convert a malleable VI into a polymorphic VI for the purpose of backwards compatibility. I'd like to have a reference library that uses malleable VIs but create a version that is still accessible to someone using older versions of LabVIEW that don't officially support malleables.

jacobson 24 Report post Posted August 6, 2018 I couldn't find a method for "Convert Instance VI to Standard VI" as you can from the right-click menu but it looks like if you get the VI reference from the subVI you get a reference to the instance VI so you could potentially just copy the block diagram and put it into new VI (reconnecting the terminals might take some work). I'm not sure what the best way would be to figure out whether the subVI is a VIM. If you grab the subVI reference and try to pull the VI Path you just get <not a path> and the VI name returns some crazy UID. 1 Quote Share this post Link to post Share on other sites

Yeah, I think the explanation given to me was that the contents of the .vim file on disk are no different than the contents of a .vi file on disk. So since it's technically not a different file type, they thought it didn't warrant a new enum entry. Kinda like how there's not a "Template VI" entry in the list since .vi and .vit are the same type on disk. I may be misremembering though so don't take this as the official answer.
