Count your blessings; to make VB look right, you have to use ''# as the comment character. – mmyers Mar 2 '10 at 19:57
@mmyers: no, to make VB look right you have to resort to controlled substances. – squillman Mar 2 '10 at 20:16
Deferred to google, since they own the syntax-highlighting code. – Joel Coehoorn Mar 2 '10 at 21:26
I do not envy the person whose job it is to determine that i-- is not a comment but --comment is, but make --install is not... – Mark Henderson Mar 2 '10 at 23:56
I assume that the code attempts to identify the language first, and then falls into a language-specific highlighter. Once it understands that it's in SQL (and I suspect that it does, since Employees seems to be highlighted as a table name, although it could just be keying off the uppercase and assuming it's a classname), recognizing a -- comment should be trivial. – sidereal Mar 3 '10 at 1:43
I think it just highlights any capitalized words (except words in all-uppercase). – mmyers Mar 3 '10 at 16:40
@Joel Coehoorn, We wouldn't have to wait for google if they (SO Team) allowed class attribute on the pre tag.… And they could only accept supported languages as the class attribute's value to avoid trickery with the site's layout. – çağdaş Mar 4 '10 at 8:07

In this case I suspect the problem is that the code is detected as a language other than sql, but I could be wrong about that. Either way, the syntax highlighting is done using google's prettify.js tool, so I deferred the request.

Although this example was trivial enough that I could imagine it not recognizing the language, the impetus for the report was a question on the main stackoverflow site where it was clear it recognized SQL (select and where keywords were highlighted, etc), but a comment wasn't recognized. – sidereal Mar 3 '10 at 1:46

The code block should recognize every language ever known, and highlight the syntax appropriately. Let's get this fixed.
