Parameters
- provider

The identifier of a DDEX provider.
- connectionString
Type: System.String
An unencrypted or encrypted string containing connection information.
- encryptedString
Type: System.Boolean
Indicates whether the connectionString parameter is encrypted.
Return Value

Remarks
If there exists a data view hierarchy with connection information equivalent to the information passed in, the method returns the existing data view hierarchy. Otherwise, a new data view hierarchy is created.
The creation of this hierarchy may cause a connection to be opened in order to generate the name of the hierarchy root node. To avoid opening the connection, call the other GetDataViewHierarchy method, passing in a non-nulla null reference (Nothing in Visual Basic) value for the name parameter.
