Overview

LabVIEW gives you the ability to use .NET Assemblies through several .NET nodes. Using these nodes, you can instantiate .NET objects, invoke functions and access properties of .NET classes and objects. In addition, you can host .NET UI Controls on the LabVIEW front panel.

To Instantiate a .NET Object

Use the .NET Constructor Node (Functions Palette » Connectivity » .NET » Constructor Node).

Also, use the Close Reference VI (Functions Palette » Connectivity » .NET » Close Reference) to destroy an object you have created.

For details, refer to:
Instantiating .NET Objects from LabVIEW

To Call a Method on a .NET Class / Object

Use the Invoke Node (.NET) (Functions Palette » Connectivity » .NET » Invoke Node).

For details, refer to:

Calling Methods and Accessing Properties of a .NET Class / Object

To Access a Property on a .NET Class / Object

Use the Property Node (.NET) (Functions Palette » Connectivity » .NET » Property Node).

For details, refer to:

Calling Methods and Accessing Properties of a .NET Class / Object

To Host/Embed a .NET Control on the LabVIEW Front Panel

Use the .NET Container (Controls Palette » .NET & ActiveX » .NET Container).

For details, refer to:

Embedding/Hosting .NET UI Controls on a LabVIEW Front Panel
