Make sure to include support for.NET when installing this driver. This will allow you to utilize the functions which you will need in your application. Good places to learn more about using these functions are in the help file or the examples which will also be installed. <a href="http://zone.ni.com/devzone/cda/tut/p/id/5409" target="_blank">This</a> article gives a brief introduction on using DAQmx in a text based programming language. Additional information on DAQmx programming in general can be found <a href="http://zone.ni.com/devzone/cda/tut/p/id/5434" target="_blank">here</a>.
