Edit / View Microsoft Outlook NK2 Name Cache File

I am trying to find some code that shows how the Outlook NK2 name cache file can be opened. I did some searches and I saw several people say that this is not possible, but then I find links to some free programs that can do just that, so I know it is possible. I would use free apps, but would prefer to do it in my own code, and it is easier for me to get approval from management if I use my own code within my organization, rather than a free / shareware app. I am trying to write code in VB, but I would like to find an example in any language if it helps.
