Hello PALMEI,
as you probably found out that there is no NI-CAN driver that does support both, CVI 5.x and LabVIEW 7.1. Here is an overview of the different NI-CAN driver versions and the supported ADEs:
KnowledgeBase article # 2V27R4HRHowever, I took the CVI 6.0 compatible nican.h file and the .lib files from the NI-CAN 2.2 driver and attached them. Depending on your compatibility mode ('Microsoft Visual C' or 'Borland') you need to copy the appropriate libraries to your local CVI directory. I'm not 100% sure, if the CVI 6.0 files work with the 5.0.1 version, but I think it
should work.
