On a PHP-based web site, I want to send users a download package after they have filled out a short form. The site-initiated download should be similar to sites like download.com, which say "your download will begin in a moment."

You are best using a ObjectDataSource when you wnt to do more complex Linq and bind your Grid to the ObjectDataSource.

In short, you may either parse the whole page and pick things you need(for speed I recommend looking at SAXParser) or running the HTML through a regexp that trims of all of the HTML... you can also convert it all into DOM, but that's going to be expensive especially if you're shooting for having a decent throughput. |
If you are using Windows the traditional place to start is [Petzold](http://www.amazon.com/Programming-Windows®-Fifth-Microsoft/dp/157231995X/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1221565730&sr=8-1)

You seem to want to screen scrape. You would probably want to write a framework which via an adapter / plugin per source site (as each site's format will differ), you could parse the html source and extract the text. you would prob use java's io API to connect to the URL and stream the data via InputStreams. |
Sorry, FF / Chrome both report this error but in very silent way. You need to go to Firefox 3.0 Javascript errors dialog to see if is there any error and for Chrome you need to go to Javascript console.

Properties should be fast, as they have a certain promise of just being there. They are also mandatory for databinding.
And they should have **no side-effects**. |
If using python, take a good look at Beautiful Soup (http://crummy.com/software/BeautifulSoup).
An extremely capable library, makes scraping a breeze. |
If you want to build the debug variants of the boost libraries as well, you have to invoke bjam with the option `--build-type=complete`.
On Debian, you get the debug Python interpreter in the python2.x-dbg packages. Debug builds of the Boost libraries are in libboost1.xy-dbg, if you want to use the system Boost.

You need to call OS-specific functions for filesystem traversal, like `open()` and `readdir()`. The C standard does not specify any filesystem-related functions. |

It is not likely that "with" would make the code run faster, it is more likely that the compiler would compile it to the same executable code.

I guess it depends on what triggers the update to take place, if it is in a validation routine you could simply call that after the user clicks OK on editing the data.
