Missing function/release notes for NI-DAQmx

[WM_John_Weeks]

A customer just wrote to say that he's using NI-DAQmx 7.5 with software that I wrote, and that it fails to start saying "The procedure entry point DAQmxGetDevCIPhysicalChans could not be  located in the dynamic link library." Clearly, I developed with a later version of NI-DAQmx.

I'd like to be able to give good information on what version of NI-DAQmx is required. Can anyone tell me how to figure out when a given function was introduced? I've searched the Support area for release notes on NI-DAQmx without success.

John,

Thank you for posting on the NI forums. There is not a real good way for us to determine what VIs were introduced in what versions of DAQmx. Could you tell me what version of DAQmx that you were developing with and then what version of LabVIEW your customer has? If you have them upgrade to the latest version of DAQmx that is supported for that version of LabVIEW that would be the easiest option. We have a document online that provides a reference for what versions of DAQmx will work for different versions of LabVIEW. Hope this helps.

Thanks, Aaron.

I see that I wasn't very careful in my posting- I am developing in C++ using Visual Studio. I also confess that I can't remember exactly which version of NI-DAQmx I had installed when I wrote the code.

Clearly, I could simply require the latest version of NI-DAQmx, but I'd like to be more lenient than that.

The What's New in DAQmx articles are pretty good - 8.3 was when the bulk of the device properties were added. For device specific properties we add them with device support, which you can get from the DAQmx Readmes. We do have a list of new features in each readme, but we don't document the specific properties... I'll see what we can do to get those added. 

Cheers,

Andrew- The What's New link helped. It turns out the particular property that I asked about was present in 8.0, where the What's New claims that "Querying of Device Capabilities" was added.

Thank you!
