I was searching an hashtable implementation for XL 2K VBA and found yours.
I copy/pasted your code inside an Type object declaration but I did not even achieve to compile it.
How should it be used ? Sorry, I'm newbie to XL VBA

You need to copy the code into a VBA class. From the command bar, choose to insert a class object into your Visual Basic project. Then, double click on the empty class in your project and paste the code from this tutorial into your project (it is easiest if you use the download code option from the menu).

I am interested in incorporating the class into an Excel project. In the article, you state that "[you] intend to illustrate how a hashtable works by using an class in VBA code that I found a long time ago on the Internet." However, you did not specify under which license it is released.

I have never been able to find the code again and am unsure as to what licensing terms apply to it. There was no license terms or attribution attached, otherwise I would have included them with the snippet.

Here is the original article: http://www.devx.com/vb2themax/Tip/19307
It looks like they are cool with non-commercial use.
