Hi Paul:
Once you have the NI-DAQmx drivers installed to communicate with your DAQ device, you can use a variety of programming languages. You can use the DAQ Assistant in LabVIEW for a "wizard" interface or use the lower level DAQmx functions to write your code. This second part can also be done in a number of text-based programming languages as well including C/C++ and the .NET languages. You can find some more information on using text-based languages here.
