Flush Method (ADO)
Forces the contents of the Stream remaining in the ADO buffer to the underlying object with which the Stream is associated.
This method can be used to send the contents of the stream buffer to the underlying object: for example, the node or file represented by the URL that is the source of the Stream object. This method should be called when you want to ensure that all changes that were made to the contents of a Stream have been written. However, with ADO it is not usually necessary to call Flush, as ADO continuously flushes its buffer as much as possible in the background. Changes to the content of a Stream are made automatically, not cached until Flush is called.
Closing a Stream with the Close method flushes the contents of a Stream automatically; there is no need to explicitly call Flush immediately before Close.
