NIScope.Dispose Method

public void Dispose()

Public Sub Dispose

Implements

A call to this method disposes the SafeHandle class used to hold the instrument handle. If the call to this method fails for some reason (e.g., the session was closed by some external means) you will not be notified about the failure. To help you identify failures in the ReleaseHandle method of the SafeHandle class, managed debugging assistant (MDA) is activated.

For details refer to http://msdn.microsoft.com/en-us/library/85eak4a0.aspx.

The call to this method fails when you externally close a session by:

• Initializing a session with a resource name for which the session is already open, within the same process. This causes the instrument handle held by the existing session to become invalid.
• Getting the instrument handle out using GetInstrumentHandle and closing this handle directly.
