在vc++开发过程中，有时候需要将数据以二进制方式存储在数据库中，本代码就是实现这一过程的示例，VC++使用ADO实现BLOB二进制大对象数据的存取，其存取的方式与普通数据有所区别，并给出实现图像存取显示的完整示例工程。

-In vc++ development process, and sometimes need to be binary data stored in the database, the code is an example of realization of this process, VC++ using ADO BLOB binary large object data to achieve access, the access ways and common data be different, and gives access to display the full Image examples of works.
