将按钮调暗为 MSH.HTMLElementCollection

Dim buttons As MSH.HTMLElementCollection

类型错误.那应该是一个 IHTMLElementCollection .注意前面的 I.MSDN 页面 在这里.

Wrong type. That should be an IHTMLElementCollection instead. Note the leading I. The MSDN page is here.

缺少 I 的类型是 coclass，而不是接口.由脚本客户端在想要创建自己的集合对象时使用.

The type that is missing the I is a coclass, not an interface. Used by scripting clients when they want to create their own collection object.
