It's been a while since I had chance to write an article. The reason it normally takes so long is that I have to search for the inspiration to sit down and spend a couple of hours explaining a technique in detail. For the last month or so I've been sat on a demo database, which, although ready for release, has been waiting for an article to accompany it. Instead of waiting any longer I've changed tack.
As with a lot of my articles it's the demo/download database that you're most interested in. My ramblings and explanation of the code are merely a wrapper around it. So, I've published a short article that explains what the database is and the basic idea on which it works. I'm sure you're more than capable of working out how it works for yourselves.
In doing this I should be able to release a lot more stuff in a much more timely fashion. Like the latest article Appending Rich Text Edits.
