public function GetDataViewHierarchy(
    provider : Guid, 
    connectionString : String, 
    encryptedString : boolean
) : Object

Parameters

provider
Type: System.Guid

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

Type: System.Object
Returns a data view hierarchy with the specified DDEX provider and connection information.

Exceptions

Exception	Condition
ArgumentNullException	The connectionString parameter is null.
ArgumentException	The specified provider is not a registered DDEX provider.

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.
