The Vi Analyzer asks me to close the refernce created by "read from text file" VI. So, I'd like close a refnum created by "read from text file" primitive VI. I used direct wiring, wiring through up and down casting, but all of them show up class conflict (see the screenshot below). Is it even possible to properly transform the refnum (byte stream type reference) to reference (generic VI reference) and remove the refnum?
