虽然退出程序时这些对象的指针都被自动施放了，但是如果你自己又不能确认是否真正地释放了打开的数据库对象，那么就有可能数据库连接没有马上被释放掉，从而被这些对象所占用的内存就再也不能被操作系统再次分配计算机通过地址读写地址对应的内存的值，完成变量的赋值和访问值的功能
常用于通过重定向将属性从一个请求传递到另一个请求下面是一个典型的例子，检测字符串中是否包含一个元音字母：
1、普通的方法：
IfUCase$(char)="A"OrUCase$(char)="E"OrUCase$(char)="I"OrUCase$(char)="O"OrUCase$(char)="U"Then
'itisavowel
EndIf
2、更加简练的方法：
IfInStr("AaEeIiOoUu",char)Then
'itisavowel
EndIf
同样，通过单词中没有的字符作为分界符，使用InStr来检查变量的内容
