Didn't we first find out about VI scripting through VI's that NI forgot to password-protect? When password-protected VI's are run, the computer surely accesses the block diagram at one point or another, so obviously it is possible to read the block diagram. LabVIEW just won't let us see it. Can anyone find any way to force it to show you? Perhaps by hex-editing the files or even using Cheat Engine or something?
