One of the best, yet often overlooked, features of ASP.NET 2.0 is health monitoring. I believe it is absolutely essential to be notified of any problems with your web application, and this is where health monitoring comes in handy. A few years ago I wrote an article about custom error pages and demonstrated various ways to tap into error details. Health Monitoring is a natural progression of that approach.

I saw a December MSDN article, entitled Uploading Files in ASP.NET 2.0, and wanted to offer my comments on some gotchas with uploading files. I’ve spent countless hours and tried numerous hacks to tame file uploading and have enough bruses from hitting my head against the wall (figuratively speaking).

Session_Start or Session_OnStart?

Posted on December 18, 2005

Ever since I started to develop with ASP.NET, I’ve been wondering why global.asa from the ASP days quietly moved over to ASP.NET as global.asax. When you look at it, it just feels so outdated, so VBScript-ish, so loosely–typed. And what is the right way to name event handlers?

Even though the spec defines CSS as a style sheet language, this language is missing one of the essential features: variables. Every time I've seen people in newsgroups ask how to implement variables in CSS a typical advice was to build the style sheet on the server. Luckily, it is easy to do in ASP.NET with the help of HTTP Handlers.

You found an article online and want to print it to nicely punch thee holes on the side and store it with other useful stuff. Almost every site nowadays provides a printer-friendly page of this and that, but some sites don't and you're still stuck with staring at their printed navigation bar, footer, ads, etc, for ever and ever.

Beware Of Deploying Debug Code In Production

You have spent several months developing a killer web application (a web site, perhaps) and the long anticipated release day has come. You deploy the application and take it for a test drive. As you navigate from page to page you notice that each page “thinks” before rendering. What’s going on? Didn’t Microsoft folks promise code compilation and ultra fast execution? Isn’t it why we beat ASP, Java and PHP by such a wide margin?

When you create a web form in Visual Studio.NET using the canned "Web Form" template you might ask yourself, "What is this DOCTYPE declaration about?"

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

What is this strange-looking beast?

Skinning Web Applications with CSS

Posted on February 22, 2004

8 comments

The common approach to skinning web applications lies in reshuffling controls on a page. Traditionally developers define templates with different color schemes and/or control positioning, tables and inline font tags. While this used to be a perfectly viable solution the overhead of run-time application of these skins is staggering. A much better way is to separate skin structure from presentation and let CSS take care of the layout and typography.
