In classic ADO (ActiveX Data Objects), is an ADO Connection object created only after an ADO Errors collection is created, or is the Errors collection owned by the Connection and populated after operations?

Introduction / Context:
Classic ADO exposes a Connection object that represents an open connection to a data source. It also exposes an Errors collection that contains provider-specific errors for the most recent operation on that connection. This question asks whether the Connection is created after the Errors object, which would invert the normal lifecycle.

Given Data / Assumptions:

• ADO objects include Connection, Command, Recordset, and the Errors collection.
• The Errors collection is a property exposed by the Connection (and also accessible via a global connection context in some environments).
• Errors are populated when operations fail or return warnings.

Concept / Approach:
The normal sequence is to instantiate a Connection object (CreateObject or new ADODB.Connection), set its properties, and call Open. Only after executing operations can the Errors collection be populated with any generated errors/warnings. Therefore, the statement that the Connection is created after the Errors object is incorrect; the Errors collection logically belongs to the Connection and is populated post-operation.

Step-by-Step Solution:

Verification / Alternative check:
Write a minimal script that opens a bad connection string, catches the error, and inspects Connection.Errors to confirm that entries exist after, not before, the operation.

Why Other Options Are Wrong:

• ADO.NET is a separate technology with different classes and does not use ADO’s Errors collection semantics.
• DSNs and pooling do not change object creation order.

Common Pitfalls:
Confusing ADO and ADO.NET; expecting a global “Errors” object independent of any Connection; forgetting to clear or re-inspect Errors after each operation.

Final Answer:
Incorrect
