The result was keep. There's a consensus here that the subject itself is notable. If there are any WP:HOWTO issues, which seems unlikely from the discussion, they can be dealt with through the normal editing process. Ron Ritzman (talk) 14:11, 26 January 2011 (UTC)[reply]
Wikipedia is not how-to content. Reaper Eternal (talk) 15:17, 18 January 2011 (UTC)[reply]
This is a HOWTO. It has no encyclopedic content beyond a straight reproduction of the language reference manual. There is no context outside the MS VB family, no discussion of how undef, Null or NaN are evaluated by comparable tests in other languages. The scope is unencyclopedically narrow, focussing only on how to achieve one task, on one platfrom. Fortunately it's not as uselessly patronising as the MSDN article, but that's just MSDN for you.
