操作系统从Win7 开始变成了64 位系统，导致VB下基本的界面操作都变得很卡，原先提供的众多命令、函数 等不能正常运行。幸好快捷而且强大的数据库连接工具ADO依然正常，但操作系统、数据库版本、链接库版本、数据库信息量 都会对数据产生影响，教程的理论分析与实际情况往往存在差异，对此本文主要分析笔者在编写程序时遇到的实际问题、困惑 以及解决方法。

The operating system changing from Win7 into the 64 bit system has lead the VB operation interface to be not smooth, and the commands and functions cannot work properly. Fortunately, the database connection tool ADO is still normal. However, operating system, database version, linking library version and database information will have an impact on the data. And there are differences between the theoretical analysis and the actual situation of the tutorial. This paper mainly analyzes the practical problems encountered in programming and its solutions.
