实例一:分页显示及导航:
为什么我要再提分页的这个问题呢?因为这是一个最基本的问题,虽然有很多关于分页的文章,但我觉得他们的方法偏于复杂。其实RecordSet的AbsolutePage就可以轻松的实现分页,当你指定了PageSize属性后,对AbsolutePage指定值就可以翻转到指定的页面。但是如果你想使用AbsolutePage的话,你必须在打开RecordSet对象之前将它的CursorLocation值设为adUseClient,这个属性是继承Connection对象的一个相同属性的。你也可以在打开Connection对象之前来设定它。下面是源代码,为了方便,我将导航栏独立成了一个子程序方便大家使用。
