This lesson explains the critical distinction between an interface and a class when working with the SOLIDWORKS PDM API in VBA.
It covers the theoretical reason why a specific object type must be instantiated in memory, provides the exact syntax for declaring and creating the vault object, and demonstrates a basic debugging test to verify the object’s initial state.
Key Takeaways:
- Instantiation Rules: Memory cannot instantiate an interface (IEdmVault5); developers must call the new instance using the class (EdmVault5).
- Status Verification: Understanding that a newly instantiated vault object defaults to an unauthenticated (IsLoggedIn = False) state until an explicit login command is executed
