摘　　要：基于ASP技术的文件上传/下载服务是目前Web网站实现客户端和服务器端交流信息的一种常用方式,它主要是通过FSO(FileSystemObject)对象实现的。FSO可以实现创建、复制或移动一个文件等基本操作,但它无法直接操作二进制文件,导致图片上传和维护不便。在"华中农业信息网"的管理实践中,借助于ADO的Stream对象设计了Web图片信息发布上传系统,获得了良好效果。对相关技术、设计思路进行了讨论,并给出了系统中的主要功能模块及关键代码。The service of uploading/downing files is usually supported by ASP, embedded with FSO(File System Object), to realize the communication between the server and the client. With FSO, a file can be created,copied and moved etc. It makes the transfer of binary data file difficult for that FSO can't cope with binary data file such as a picture file directly. This paper introduces a new method of the automatic transfer of binary data file which is based on ADO Stream component object. It runs well on the website of Central China Agricultural Information Net. This paper discusses the related technologies and discribes the main functional modules and key codes detailedly.
