You can use LabVIEW ActiveX Invoke and Property nodes to access the complete functionality of the Session Manager server.

The following figure demonstrates how to use the TestStand Session Manager - Get Instrument Session VI to obtain an instrument API handle:

Note   Instance handles that an instrument session creates are C-based API handles. Attempting to share C-based VISA, VXIplug&play, IVI C, or NI Switch Executive instance handles across processes results in an error. For example, you cannot use an IVI C-based handle that a step in the TestStand process creates in a VI code module that executes using the LabVIEW development system process.
