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.
