How to use DAQmxGetDevProductNum and DAQmxGetDevProductCategory?

[David_Lin]

Hi, Kalyan,

I finally figured out what's wrong with my code. It seems I used old version of NIDAQmx.h and NIDAQmx.lib in my project and after I replaced them with new version which are much bigger than the old ones, the program can compile and run. Thank you very much!

Now I have only the last question in my previous post. The functions DAQmxGetSystemInfoAttribute and DAQmxGetDeviceAttribute could not be found in the NI-DAQmx C Reference Help. Can you tell me where they are introduced? Is it true that DAQmxGetSystemInfoAttribute and DAQmxGetDeviceAttribute is for CVI only as said in other posts?

Thank you very much!

David

Hi David,

It is true that "DAQmxGetSystemInfoAttribute" and "DAQmxGetDeviceAttribute" are shown explicitly in CVI and they are documented in DAQmx C Reference Help. THowever, these two attributes can still be used in other VC++. The equivalent ones referred are DAQmxGetSysDevNames etc.,

Hope this helps.

Thanks,

Kalyan
