We must've done something right when we wrote this sample, because it's ten years later and users are still using it and even sending us their own customized versions. Quite a few changes in this version. If any of these features are something you think might be useful, download it and give it a whirl!
Our login and password sample code has always been case-sensitive. While we don't really recommend it, if you must make your usernames and/or passwords case-insensitive, it's actually quite easy to do.

As a developer, repetitive code is your enemy. It takes longer to write, leads to larger files, and is harder to maintain. Which brings me to the point of this tip. Did you know that you can tie the same event handler to multiple objects? It's easy to do, but most people never think to try it.

Microsoft just published a series of 46 -- that's right 46! -- tutorials that provide step-by-step
instructions for implementing the different controls in the ASP.NET AJAX

There are times when it's nice to have a full blown development environment like
Visual Studio to mangage your site with, but there are also times when a simple little
web app fits the bill perfectly.

Last week while I was talking with a friend of mine, he asked me a couple questions and then told me when I could expect my economic stimulus payment. This sample does the same thing. It's nothing fancy, but it does illustrate some basic form handling, conditional branching, and a good use of a Select Case statement. Give it a try... hopefully your payment is coming soon!
Why do people insist on using mm-dd-year or dd-mm-year when creating
log files? Are you really trying to see what happened on the same
month of every year or the same day of every month? You might want

the files into chronological order.
This sample shows how you can query a database table for multiple search terms.
Whether you want the results that match any of the search terms or you just
want results that match all of them, the process really isn't as hard as you might think.
I recently started getting some odd characters appearing when
working with an old classic ASP application. I'd been using the
same scripts for years and while I knew that nothing in the
application had changed, we'd recently started using Visual Studio
2008 to create the application's data files.
While ASP.NET server controls make developing Web pages much simpler,
sometimes they don't output their HTML exactly the way you'd like them to.
That's where the Literal Web server control comes in. Unlike most

It sure took Microsoft long enough to add decent style sheet support
