摘要：

BLOB fields in database can store BLOB (Binary Large Object) such as graphics files, audio files and large format text files etc. This article introduces a simple and efficient method to access BLOB data in database by internal objects of ADO (ActiveX Data Object) in Visual C++. We also illustrate the working principle and working process of the method, which provides an efficient approach for the developing of multimedia information systems.
