A common problem that one often runs into with XML literals and the LINQ to XML API is duplicate XML namespaces. Consider the following example. The code imports a default XML namespace - “hello”.Code: Imports <xmlns="hello"> Module Module1 Sub Main() Dim x = <A> ...
VB XML Cookbook, Recipe 7: Enumerating Large XML Files (Doug Rothaus)It’s been a while since I wrote one of these XML cookbook entries. Here’s some info on a common problem: Really big XML files.I’m going to show you two things in this recipe. The first is a tip on reading very large XML files while still being able to use XML Axi...
One of the common use-cases of XML literals is creating HTML. However, HTML entities cannot be used in XML literals since LINQ to XML directly supports only the Data type definitions (DTD) defined in the XML 1.0 spec. You can read more about it here. The workaround is to use the Unicode representation of the entity, although it’s not as readable ...
The implicit line continuation feature in Visual Basic 2010 provided an opportunity to improve the code editing experience in XML literals embedded expressions. In Visual Studio 2008, pressing Enter inside an embedded expression would result in the cursor being positioned to the left of the end embedded expression tag. In Visual Studio 2010, pressi...
A while back, I remember being asked if there was a simple way to expose a source XML document as an object with properties. That is, if the root XML element had a child element <Name>Doug</Name>, then the object would have a Name property that was a string and returned “Doug”. The catch was that the XML document did not con...

In this post, I’ll continue on with coding the new playlist shuffler. If you haven’t read part 1 yet, I highly recommend it so that this post will make more sense. JCode for the controls (continued)The Title TextBoxWhen the title changes, we’ll want to indicate that the playlist has changed, and we’ll want to cache the...
Way back in October 2007, I wrote up a few posts (here and here) on my experiments with the Windows Media Player object model. The problem I was trying to solve was that, when I had a playlist set to “shuffle,” WMP would break up songs that should always play together (for example, Jackson Browne’s “The Load-Out”...
Steele wrote a great article in last month's issue of Visual Studio Magazine on XML Literals, WCF and LINQ. He shows how to use these three technologies together to produce more responsive ASP.NET pages, and more readable code. Lots of great tips for VB 2008.VSM's "On VB" Column: XML Literals, WCF and LINQ by Steele Price

Hi,I posted a bit of code the other day which I used to get a list of all Code Snippets we ship in Visual Studio. In a nutshell, I used XElement.Load to create a new XML document from a filename from which I then read elements from (There are way to many ‘”from” in this sentence ;-) ). Unfortunately, I forgot to import the XML Nam...
