Get Component IDs Example (VB.NET)

This example shows how to get the component IDs of the components in an assembly and subassemblies.

' Preconditions:
' 1. Open an assembly document containing nested subassemblies.
' 2. Open the Immediate window.
' Postconditions:
' 1. Traverses the assembly and subassemblies.
' 2. Gets the name and component ID of each component in the assembly and
'    subassemblies.
' 3. Examine the Immediate window.
