ADO Stream Object
Stream Object (ADO version 2.5)
The ADO Stream Object is used to read, write, and manage a stream of binary data or text.
A Stream object can be obtained in three ways:
- From a URL pointing to a document, a folder, or a Record object
- By instantiating a Stream object to store data for your application
- By opening the default Stream object associated with a Record object
