What is the difference between NI_DataType and Datatype properties?
Thanks to Excel Importer I can check the Datatype properties and see e.g. that my channel is of type DT_DOUBLE.
However, when I try to read this property it can't be found.
I need to create the tool in LabVIEW which loads TDMS file, alter it and then save it preserving the original file structure (data types). Now I'm a bit confused about what property should be used to accomplish my task.
I have two groups: One with waveform channels and second with numeric channels. If I read waveform channel NI_DataType I'm getting 10 (which can represent DBL, Analog waveform or Dynamic data). If I read my numeric channel NI_DataType I'm getting 0 which is not correct.
Excel returns DT_DOUBLE Datatype property for both channels.
So how to properly determine the data type?
