I'm teaching (or trying to teach) computer programming to a grad-student. Her previous experience amounts to little more than writing spreadsheet formulae. Which IDE or text editor should I recommend?

I'd be interested in this too. I'm coding several apps that uses automation in Word and I even have things like

Compacting an Access database (also known as a MS JET database) is a bit like defragmenting a hard drive. Access (or, more accurately, the MS JET database engine) isn't very good with re-using space - so when a record is updated, inserted, or deleted, the space is not always reclaimed - instead, new space is added to t... |

I'll reply with a different approach of the problem. My approach is to store the lengths in seconds. Then depending the needs, it's easy to render these seconds as hh:mm:ss by using :
`print gmdate($seconds >= 3600 ? 'H:i:s' : 'i:s', $seconds);` (for your question)
or to search on the length in a database:

Nooooo!!! Don't implement method\_missing on your controller! And please try to avoid action_missing as well.

Referenced Assemblies in Web Site |

If you want to log on a specific page, I believe asp.net pages' lifecycle begin with PreInit and end with Disposed, so you can log anything you want in those events.
Or, if you want to log on every page, as Bob Dizzle pointed out, you can use the Global.asax file, which has a thousand events to choose from : http://... |
These "small words" are considered "noise words" by the full text index. You can customize the list of noise words. This [blog post][1] provides more details. You need to repopulate your full text index when you change the noise words file.

Personally, I'd get more data from the database through fewer methods and then bind the UI against only those parts of the data set that I currently want to display. Managing lots of small methods that get out specific chunks of data is harder than getting out large chunks and using only those parts you need. |

You should start with **[vim][1]** (Vi IMproved) and especially its GUI - **gVim**. The GUI has menus and on Windows you can use the copy, cut and paste shortcuts, so you can replace Notepad immediately. And since the menus display the shortcuts (vim commands) you could learn a lot.
