  • Multiple domains with the ASP.NET 2.0 HttpHandler

    Here is my problem: I own many domain names (too many my wife says ) and I want to be able to do serve .NET pages for potentially each of them, but I don't want to have an account for each domain name. Essentially I want the users not to know that they are using the same application on a server for different domains. I don't want to redirect either as the urls will give it away. I'm sure many other domain junkies must have this same issue. To achieve this I do the following: Firstly I...

  • ASP.NET Podcast

    I haven't posted anything in ages and I realise this is probably not my most researched post, but I do think this would be very useful to the rest of the ASP.NET community. Wallace B. McClure (a Yank) publishes the ASP.NET Podcast ( rss ). For those of you that are into podcasting as I am, this is well worth a listen. This week he interviewed Shanku Niyogi and Nikhil Kothari, two of Microsoft's top ASP.NET guys, regarding Microsoft's Atlas project for ASP.NET. Share this post: email it! | bookmark...

  • ASP.NET's error-handling idiosyncrasy

    I have recently been exposed to an idiosyncrasy in ASP.NET's standard error-handling. For those of you that might not know, the following is what happens. If your application errors, ASP.NET rebuilds your session from what it was before the error. This is great, BUT it means that any session manipulation (i.e. adding a error message to session) you do will get lost as soon as the error redirect (as specified in web.config) occurs. Of course the LastError also gets reset, so you're not able to show...

  • Visual Studio.NET IDE matures with 2005

    I find 2005 an absolute pleasure to work with sofar. Apart from some expected (this is only Beta 2) bugs I think they have done really well in maturing what was already there as well as adding some new very useful IDE enhancements. Just some of the stuff that I'm very happy with: One of my pet hates was the awful way in which VS.NET used to reformat HTML when you switch from "HTML" mode to "Design" mode. They have now seen the light and leave your timeously formatted HTML excactly as it was! The...

  • Improve XSLT transform performance with XPathDocument

    Provided you know XSL, there is hardly an easier way to transfrom xml to more xml, text or html than using XSLT. If you're doing this in .NET there are some things that you should keep in mind: Don't use XmlDocument as the source of an XSLT transformation; rather use XPathDocument . Basically you can't do much with XPathDocument other than calling its CreateNavigator (implements IXPathNavigable.CreateNavigator ) method. This method will return a read-only cursor model based on the XPath data model...

  • Why AJAX? The benefits of AJAX explained.

    While reading the comments on Armand's AJAX Wrapper DLL post , I got the impression that readers weren't quite sure about the benefits of AJAX. AJAX has two huge benefits: Speed and invisibility (ala smart client) makes for a very slick user experience. The smaller server resources footprint helps server scalability (seriously!). I'll explain. If you post using AJAX, only the data (or parameters) that the server function requires is posted. In a login scenario, only the username and password strings...

  • Complicated configuration settings with a custom ConfigSectionHandler

    Most of the time when you need configuration settings for an application, they have to be simple name/value pairs. For instance: connection strings, timeouts etc. Occasionally though you might want more complicated or hierarchical configuration settings. For instance: a complicated and/or conditional route that an MSMQ message should take. This is when you can use a custom Configuration Section Handler. Building a custom configsectionhandler is easier than you'd think. Essentially it requires 4 easy...

  • ASP.NET/DHTML Menu User Control

    Check out this wicked Menu control . It won Codeproject 's Februarie 2005 prize. It has been designed to work most browsers. In fact, I can't think of any right now that it doesn't support. Personally I prefer to stay away from user controls (I prefer XSL where possible), but I have to say that this is a pretty neat and usable piece of code.
