Parameters

• provider
  Type: System.Guid

  A DDEX data provider GUID.

• connectionString
  Type: System.String

  A connection string recognized by the data provider.

• encryptedString
  Type: System.Boolean

  Indicates whether the connection string parameter is encrypted (true if encrypted).

Remarks

This method allows a client to indicate that a data connection currently being shared is known to no longer be valid. For example, a client feature that deletes a database file may invalidate any connections to that file. After invalidating the connection, the next client to request a data connection that matches this invalidated connection will get a new one rather than the invalidated one.
