.NET ArrayList - HashTable - Dictionary Base

[gmaxey]

Mana from Japan, I hope you see this question as it is related to a thread that you participated in last week.

http://www.vbaexpress.com/forum/show...e-for-red-text

While I dabble in VBA with Word mostly and occasionally in Excel an Outlook, I do not consider myself a programmer. Far from it. In fact, normal programming languages such as C+, Java, VB, .Net is to me for the most part a riddle wrapped in a mystery inside a enigma.

I had tinkered with the problem for a few minutes in the morning before headed out to school and thought that I would try to solve it using a scripting dictionary. The code below shows how I would have done that. However, when I saw your use of the .NET ArrayList, I became intrigued and thought I would see where I could take it and started researching it a bit.

I thought that if it worked ArrayList worked so well in a VBA then perhaps a .NET DictionaryBase might work as well. No luck. For whatever reason, CreateObject("System.Collections.DictionaryBase") errors and while CreateObject("System.Collections.HashTable") doesn't error, the methods don't seem to work.

Do you (or anyone) know if the .NET DictionaryBase or HashTable can work in VBA?

Thanks.

mana,

Thanks. I feel pretty stupid. I had gotten as far as oHT.Add 2, "two" yesterday. As I mentioned, I wasn't getting an error like I was with Set oDic = CreateObject("System.Collections.DictionaryBase"), but I was watching the oHT object in the locals window and seeing this. I just assumed that the object wasn't taking my .Add attempts.

What about the DictionaryBase, any idea why it doesn't work while the others seem to be content?

Sorry for the late reply.
Only Partial functions of .NET Framework seems to be available.
