Hello again,
The link I sent you ( http://zone.ni.com/devzone/cda/tut/p/id/5957 ) describes the parallels between traditional daq and daqmx. Also, notice that this is only part 1. At the bottom of the article are links to parts 2,3, and 4 of the tutorial. I'll link them here for you: part2, part3, part4 . Also, like I mentioned before, I would strongly suggest running some of the daqmx examples. You can get to them by going to Start » All Program » National Instruments » NI-DAQ » Text-Based Code Support » ANSI C Examples.
Hope this helps!
