I personally would not try to re-invent the wheel here. If you already have an Excel sheet that has the formatting you want, just export the data from Access into Excel for the report. Now, if you didn't have the original Excel sheet to begin with, that would be a completely different story.

The following selector should also work in jQuery: `'input:checkbox'`.
You can then string the `:gt(index)` and `:lt(index)` filters together, so if you want the 5th to 7th checkboxes, you'd use `'input:checkbox:gt(4):lt(2)'`. |

The likely reason they're using `blockquote` is that many people dabbling in HTML don't know enough about CSS to know that a `div` can be given the same left-margin as `blockquote` renders with by default. |
As far as I know, not all the crawlers support Allow tag. One possible solution might be putting everything except the home page into another folder and disallowing that folder. |
I'm not sure there's any easy way to parse a date and work out its pattern, but I would have thought that the pattern for the one you posted would be:
EEE MMM dd HH:mm:ss zzz yyyy |
Are you just asking for the pattern for that given date? If so, I think this should do it:
"EEE MMM d HH:mm:ss z yyyy"
Or are you trying to take any formatted date, and infer the format, and parse it? |
The format to pass to SimpleDateFormat could be looked up at http://java.sun.com/javase/6/docs/api/java/text/SimpleDateFormat.html

If you're using Visual Studio, there's the option to break whenever an exception is thrown, regardless of whether it's unhandled or not. When the exception is thrown, the exception helper (maybe only VS 2005 and later) will tell you what kind of exception it is.

Depends on the implementation. What language/library/class? There may be a best case, but it would be very specific to the number of features in the implementation. |
