adodb.stream 对象详解（adodb.stream对象详解） ADODB.Stream object detail Reduces font size and increases font size The Stream object represents a stream of binary data or text. Explain In a tree hierarchy such as a file system or an e-mail system, Record may have a default binary stream of bits associated with it, which contains the contents of a file or e-mail. The Stream object can be used to manipulate fields or records that contain these data streams. You can obtain the Stream object by: URL by pointing to an object (usually a file) containing binary or text data. This object can be a simple document, a Record object or folder that represents a structured document. Open the default Stream object associated with the Record object. When you open Record, you can get the default flow associated with the Record object. You can delete a roundtrip process simply by opening the stream. By instantiating the Stream object. These Stream objects can be used to store data for the application. Unlike the default Stream for URL or Record associated with Stream, the instantiated Stream is not associated with the underlying source by default. With the methods and properties of the Stream object, you can perform the following actions: Open the Stream object from Record or URL using the Open method. Close Stream with the Close method. Enter bytes or text into Stream using the Write and WriteText methods. Read bytes from Stream using Read and ReadText methods. Writes any Stream data that is still in the ADO buffer to the underlying object using the Flush method. Copy the contents of the Stream to another Stream using the CopyTo method. Use the SkipLine method and the LineSeparator property to control how the rows are read from the source file. Determine the end of the stream position with the EOS property and the SetEOS method. Save and restore data in the file using SaveToFile and LoadFromFile methods. Specifies the set of characters used to store Stream using the Charset property. Terminat
