Issue Details

I have a National Instruments data acquisition card that I want to program in Microsoft Visual Studio or Measurement Studio. I can see the DAQmx C Reference but where is the language-specific documentation (Visual Basic, Visual Basic.NET, C# etc)?


The DAQmx C reference is the library of C functions that can be used to communicate with National Instruments data acquisition cards. 

DAQmx commands for specific programming environments can be found in:
Start»Programs»National Instruments»NI-DAQ»NI-DAQmx.NET Framework [version #] Help.

Inside, expand NI Measurement Studio Help. Expand:
Developing Projects with Measurement Studio »Getting Started with the Measurement Studio Class Libraries» Using the Measurement Studio NI-DAQmx .NET Library

Alternatively, inside of the Windows Search enter:
 NationalInstruments.DAQmx Namespace

Any function in this reference is explained in terms of all the available programming environments.
