Connections to DDEX data sources are maintained as instances of the IVsDataConnection object. Individual object instances are identified by using two pieces of connection data: the associated DDEX provider GUID and the connection string.
When a connection uses existing connection data, see How to: Retrieve a Connection Using Existing Connection Data.
When a new connection is being created by using user inputs, see How to: Retrieve a Connection Based on User Input.
