I'm trying to create an interface to allow the user to test a variety of inuts during main development. I thought NIDAQmx_NewChannelCtrl would allow the selection of a channel from a restricted set of interfaces but it lists NOTHING. The same thing happens with a variety of other similar functions. There are no examples that can be found and the documentation is worse than useless, it just lists what you can figure out from the name.
I've tried using NIDAQmx_NewPhysChanDILineCtrl but once you put the restrictions (digital input with a particular interface card) you lose the ability to select the lines, it leaves you with only the ports showing (it should default to the lines like it's name implies) unless you change the filtering (which you can't do programatically). For new people this is very confusing.
