摘　要:如果没有设置AllowBypassKey属性，那么通过编程方式在启动数据库时按住Shift键来自动避开数据库启动的自动代码。通过引用隐藏的ACCESS数据库实例来避开数据库的自动宏，你可以使用下面的函数fGetRefNoAutoexec。

　首先，祝贺

Dev Ashish于2002.11.11成功改版The access Web，使越来越多的ACCESS爱好者获得更大的帮助，在此，表示感谢。

　　常常，使用Autoexec宏来自动操作一个或多个ACCESS数据库，特别是如果开发者试图获Access对象模型(Access Object Model)，胜过使用Jet引擎(能通过DAO和ADO来获取的)。不管怎样，Access不提供任何内置的方法来有条件避开这个Autoexec宏。如果数据库包括了这个宏，一打开就会运行。当未设置数据库的AllowBypassKey属性时，可以在启动数据库时按住Shift键来避开运行这个宏。

　　如果没有设置AllowBypassKey属性，那么通过编程方式在启动数据库时按住Shift键来自动避开数据库启动的自动代码。通过引用隐藏的ACCESS数据库实例来避开数据库的自动宏，你可以使用下面的函数fGetRefNoAutoexec。
