using TC01 in MS Visual Studio c program

[fredette]

I am developing a simple c program in MS Visual Studio 2019 that includes code to get measurements from the NI TC01 thermometer. Below and attached is a stand alone version. I had a similar routine running a few years ago on a different PC and a different version of Visual Studio.

The TC01 works ok with NiMax.

The function 'DAQmxCreateAIThrmcplChan' does not work and returns an error. Any help is appreciated.

thanks, mark

My I did not realize that 'DAQmxCreateAIThrmcplChan' needs the device name, which in my case is 'Dev3'. My code had it as 'Dev1'. I found the device name in NiMax.

I changed the name in my code and now everything works. I also found some code that searches for devices, checks for a match and returns the device name. I added that to my project and it is attached.
