摘要
Visual Basic提供了多种访问数据库的方法,但通过ADO方式访问数据库时,图像数据不能直接存入数据库。结合基于VB的数据库实用软件的开发,讨论了实现数据库中图像动态地存取、显示、打印、滚动式浏览与组合的原理和方法,给出了一种存取数据库图象的有效方法,解决了在ADO方式下图像数据存入数据库的问题和图像的动态打印问题,给出了部分实例代码。
Visual Basic has provided various ways to access the database, upon ADO model, the image data can't be stored into database directly. Based on the development of database applications, this paper discussed the theory and methods of dynamic storing/retrieving, displaying, printing, scroll-exploring and assembling of images in database, and gives an effective way for storing the images data into database and accessing images from database, solved the problem of inserting the image data into database in ADO model. And then the source code of some practical instances was presented.
