基本思路是：建立一个空格字符串，其长度为要重复复制的数目，然后替换每一个空格为要复制的字符串：

FunctionReplicateString(SourceAsString,TimesAsLong)AsString

ReplicateString=Replace$(Space$(Times),"",Source)

EndFunction

但是请注意：根据字符串的长度以及重复的数目，这个方法也许比传统的循环方法要慢些即使如此，也是为了进行错误处理

有了 Default 关键字之后，我们可以模拟实现构造函数的功能： 限制f明如下：ActiveXDataObjects(ADO),version2.1MicrosoftOLEDBProviderforJet,version4.0@是Microsoft提出的ADO的延伸功能：MicrosoftJetOLEDBProviderandReplicationObjects(JRO)这个功能在JETOLEDBProviderversion4.0(Msjetoledb40.dll)及JROversion2.1(Msjro.dll)中第一次被提出

比如我想知道scrrun.dll（提供fso对象的dll）这个COM组件提供了哪些接口，可以用下面的代码： 或者我忘记了fso对象有哪些属性和方法，而又没有参考文档，可以用下面的代码： 时间和篇幅有限，举的例子比较简单，更详细的请查阅文档（参考链接2为下载地址）BASModule模块把以下代码回到BASModule模块:
