Fire Events When Display State Changes Example (VB.NET)

This example shows how to fire the events related to changing display states of a configuration in an assembly document.

'---------------------------------------------------------------
' Preconditions: 
' 1. Open an assembly document that has a configuration with multiple
'    display states.
' 2. Run this macro in debug mode.
' 3. Change the display state of the active configuration in SOLIDWORKS
'    (click the ConfigurationManager tab and double-click
'    a different display state).
'
' Postconditions:
' 1. Displays a message box informing you that the display state is about to
'    change.
' 2. After the display state changes, displays another message informing you
'    that the display state has changed.
'
' NOTE: This example also fires these events when you change
' configurations in an assembly document.
