如何在独立的.vbs文件中从VBScript调用DotNetFactory?

我一直在探索用于扩展QuickTest Professional脚本功能的选项，并且遇到了

I've been exploring options for expanding my QuickTest Professional scripting capabilities, and came across this article this morning, so I decided to experiment a bit. The code below works fine when executed inside the QTP environment, but I could see a use for this outside of the QTP environment as well. Unfortunately, it is causing an error when run from a stand-alone .vbs file

Set MyDate = DotNetFactory.CreateInstance("System.DateTime").Now
msgbox MyDate.ToShortDateString()

错误是所需对象:'DotNetFactory'"

The error is "Object Required: 'DotNetFactory'"

我以前从VBScript进行过.Net调用，但是他们都没有使用过DotNetFactory.诸如

I've made .Net calls from VBScript before, but none of them have used DotNetFactory. Code such as

Set coll = CreateObject("System.Collections.Queue")

不引起错误.

我需要设置对DotNetFactory的引用吗?文章中的文字

Do I need to set a reference to DotNetFactory? The text from the article

我们使用"System.DateTime"作为类型名称.我们不需要指定程序集为此，因为它属于已经已加载名称空间系统"(mscorlib.dll).

We use ‘System.DateTime’ as type name. We do not need to specify the assembly for this as it belongs to the already loaded namespace ‘System’ (mscorlib.dll).

让我这样想，因为脚本编辑器不会自动加载任何内容.如果是这样，我该怎么做?我不是在使用IDE，而是在使用文本编辑器，因此任何引用都必须由脚本本身加载.

makes me think so, because nothing is automatically loaded by my script editor. If so, how do I do this? I am not using an IDE, just a text editor, so any references would have to be loaded by the script itself.

更新:正如Motto指出的那样，如果没有一些额外的工作就无法完成.文章中的引文指出，mscorlib中包含了 System.DateTime 而不是 DotNetFactory .

Update: As pointed out by Motto, it can't be done without some extra work. The quote from the article was pointing out that System.DateTimenot DotNetFactory is included in mscorlib.
