Forward declaring enums is non-standard, because pointers to different enum types are not guaranteed to be the same size. The compiler may need to see the definition to know what size pointers can be used with this type.

The grey line is supposed to be there. The reason why it looks odd is because the very top is hidden by the buffer element. Remove the `background-color` rule from this ruleset:

Because simple date format you specified discards the milliseconds. So the resulting Date object does not have that info. So when you print it out, its all 0s.

I would probably construct a query that gets the instance where Primary = true. I haven't used Win32_OperatingSystem in a while, but I seem to remember getting multiple instances, and the one that was currently booted had Primary equal to true. |
The behaviour of the code is undefined. You may be lucky (or not) and it may work with your compiler, but really that's not correct code. There's two problems with it:

2. The delete should delete the same type as the new.
So to be entirely correct, you want to be doing so... |
Why is using a different parser such a problem? Bison is readily available, and (at least on linux) yacc is usually implemented as bison. You shouldn't need any changes to your grammar to use it (except for adding %destructor to solve your issue). |

The Java API has [classes][1] for manipulating JAR files.

When you parse a date it only uses the information you provide.
In this case it only knows MM-dd-yyyy HH:mm.
Creating a new date object returns the current system date/time (number of milliseconds since the epoch).

Just try to use common sense.
Also some say - and I have to agree with them - that, if you're finding yourself joining 6 (the magic number) tables together in most of your queries - not including reporting related ones- , than you might consider denormalizing a bit. |
I'd express the format as:
"1-3 dot-separated components, each numeric except that the last one may be *"
As a regexp, that's:
^(\d+\.)?(\d+\.)?(\\*|\d+)$
I'm a bit rusty, so I'm not sure about the operator precedence in that last bracket. I think it's right, but you might need (\\*|(\d+)).
