Is this information available in SubVI and how can I get it programmately?
Thak you in advance
No this information is not available (or maybe it is but not in a way that is publically available). The way I solve this usually is to set the default value to something that makes not much sense (path=empty path, floating point=NaN, integer indices=-1) for that parameter and check for that.
Beats the use of undocumented methods that can and often do change in between LabVIEW versions by miles.
