The NIDAQErrorHandler function is located in "nidaqex.h" so you will need to include that file to your project. The file is located in your National Instruments directory. On my machine it's C:\Program Files\National Instruments\Measurement Studio\CVI\toolslib\DaqUtil. To add a file to your project, from the project window select Edit->Add Files to Project.
