IIS 7 Error Pages taking over 500 Errors
April 29, 2009 @ 1:59 pm

I've been running into a problem with IIS returning error pages when my application is actually returning 500 errors along with custom content. IOW, IIS is taking over error display completely even if I send my own content for errors. This has some profound effects on error handling and on some custom handler implementations that relying on returning error information to the client. Thankfully there's a new ASP.NET 3.5 property that helps with this problem, although it's a rather obscure fix for this issue.

Creating Visual Studio Templates from your Web Projects
April 27, 2009 @ 7:38 pm

Visual Studio has the nice capability to create project templates from existing projects and with a little bit of work it's real easy to create a project environment that's ready to roll without having to dig for related components first. This applies to Web projects more than anything for me as I have a fair bit of generic utility code that is project specific and needs to be added to just about all projects. Templates make this real quick and easy. Here's how.

JSON Serialization of a DataReader
April 24, 2009 @ 5:14 am

On a few occasions recently I've ended up with DataReaders in my AJAX services. The data comes from low level componets with data from APIs over which I have no control and it feeds only feeds data from DataReaders. Rather than converting these readers into more complex data structures it can be more efficient to directly turn these DataReaders into JSON. Here are a couple of ways to do this using a custom serializer and a JavaScriptConverter for JavaScriptSerializer.

Native JSON Parsing: What does it mean?
April 19, 2009 @ 8:20 pm

The new native JSON support in new and upcoming browsers is going to improve JSON parsing performance. But there are still issues you need to deal with like the age-old JSON issue of date persistance with a JavaScript date literal. In this post I discuss various aspects of the native JSON parsers and how you can have one set of code that deals with either native parsers or the existing JSON2 interface.

A Closable jQuery Plug-in
April 14, 2009 @ 5:01 am

I've found it very useful to have a closeable plug-in that hide the content of an HTML element providing a visual close image cue. Almost every UI I build these days requires either closing pop up windows or even more commonly requires that items are removed and visually hidden which usually implies 'close' behavior. In addition to removing a bunch of HTML markup, having a plug-in is also quite useful for server controls especially if multiple behaviors (plug-ins) need to be applied.

I can’t find my Find Dialog in Visual Studio
April 10, 2009 @ 5:00 pm

Ironic ain’t it? I can’t find my Find Dialog in Visual Studio and I can’t use find to find it. Ok funny, but at the time it didn’t seem too funny because I needed to really find something in a rather large JavaScript source file. But when pressing Ctrl-F (or Ctrl-H for Find/Replace) in Visual Studio rather than getting the familiar Find Dialog I got a slight flicker and a whole lotta nothing...

A Localization Handler to serve ASP.NET Resources to JavaScript
April 02, 2009 @ 1:08 pm

Here's an implementation of an HTTP handler that can serve ASP.NET Server resources to JavaScript clients easily. The handler can provide both local and global, normalized server resources to client JavaScript pages so that you can localize resources in one place on the server. Use standard Resx resources or our custom database resource provider.
