Please could someone help me with using a NI USB-6501 from c# .net?
I just need to implement simple digital IO from an existing WPF C# application.
I do not require NI Measurement Studio.
I understand that a .NET wrapper is required for the dll and have found some example wrapper code from July 2005 here:

However I do not know where to find the required dll or even that the dll name is still correct. I have installed DAQmx from the supplied CD.

seems to suggest that I need to use the CWDAQ ActiveX control. However, when I search for this control, it has not been registered even though I have run the CD installation program.
