Use the Connectivity VIs and functions to work with .NET objects, ActiveX-enabled applications, input devices, register addresses, source control, and Windows registry keys.

Subpalette	Description
.NET Functions	Use the .NET functions to create .NET objects, set properties or call methods on those objects, and handle events for those objects in the .NET environment. You also can create a .NET control on the front panel. Creating and communicating with .NET objects requires the .NET Framework 1.1 Service Pack 1 or later.
ActiveX Functions	Use the ActiveX functions to pass properties and methods to and from other ActiveX-enabled applications, such as Microsoft Excel.
Input Device Control VIs	Use the Input Device Control VIs to obtain information about the joystick, keyboard, or mouse connected to a computer.
Libraries & Executables VIs and Functions	Use the Libraries & Executables VIs and functions to call code from libraries, such as dynamic link libraries (DLLs); to manipulate LabVIEW data for use in other applications; and to call code written in text-based programming languages.
Port I/O VIs	Use the Port I/O VIs to read from and write to a specific register address.
Source Control VIs	Use the Source Control VIs to access common source control features within LabVIEW. You must configure LabVIEW to work with a third-party source control provider before you can use the Source Control VIs.
Windows Registry Access VIs	Use the Windows Registry Access VIs to create, open, query, enumerate, close, and delete Windows registry keys. You also can enumerate, read, write, and delete the value of Windows registry keys.
