对象的前期绑定与后期绑定使用方法(CLSID-ProgID对照)

在学习字典，正则表达式等对象时，我们都知道有后绑定及前绑定的方法，
那么我们怎么知道要引用什么？又要怎样写后绑定代码呢？其实这些信息
都在注册表里面。前期绑定可以引用类型库别名或者类型库文件，字典为例
类库名称引用（A列第二行） Microsoft Scripting Runtime
类库文件引用（A列第一行） C:\WINDOWS\system32\scrrun.dll
后期绑定也有两种形式,一种是用ProgID,一种是直接使用CLSID，
以字典为例：
set d=createobject("Scripting.Dictionary") 'C列
set d=CreateObject("new:{EE09B103-97E0-11CF-978F-00A02463E06F}")'B列
其中第2种实用性更强，因为类型库必须有CLSID，但不一定有ProgID,但用ProgID
会比较好理解。
本程序可以搜索本机注册表中的所有TypeLib，将文件路径和需要的引用项目列出
在A列，将个类型库的子类列出到B,C,D列，其中B列是CLSID，C列是对应的ProgID
（可能为空），D列是对应的默认名称（可能为空）

把你的电脑上这个dll文件共享一下，我电脑win10没有这个dll文件

我也是win10，64位的1607版本可以正常运行的，安装个vb6吧。

我写这一帖的目的是方便初学者学习的，在论坛大家学习别人的代码时，
大部分老师为了大家方便利用，一般都用的后期绑定，为了便于学习各
种对象的方法，属性，还是前期绑定方便，因为前期绑定写代码时IDE
会有提示，但是对于初学者来说要找到引用条目不容易，比喻以下项目：
With CreateObject("new:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
.SetText strText
.PutInClipboard
End With
我们知道这个是利用CLSID创建对象，通过搜索CLSID我们知道知道需
要引用C:\WINDOWS\system32\FM20.DLL这个文件，但路径可能和我
的不一定一样.

今天整理代码发现类库下面的子类与CLSID是多对一，就是不同的类库
可能有相同的子类对应同一个CLSID，而在系统中一个CLSID只对应一个
默认的库文件，现在修正代码，默认的库文件放在E列
