I am developing with Visual Studio 2005 / Measurment Studio 8. Ultimately I want to control the relays on a PXI-2503. But for now I was wondering how to make use the .vi files that I see referenced when researching solutions.
If you have LabVIEW installed on your computer, you can make a DLL out of the VI and call it from .NET. Or, you can examine the structure of the driver calls in the VI and replicate it in .NET.
