Article: Sharpening Your Axis with Visual Basic 9 (Beth Massi)

In the July/August issue of CoDe Magazine there's an article I wrote with Avner Aharoni (the Program Manager on XML literals) called Sharpening Your Axis with Visual Basic 9. (They just opened up online access to even non-subscribers today!) I highly recommend this article which shows you from the beginning how XML literals, embedded ...

VB XML Cookbook, Recipe 5: The “Halloween” Problem (Doug Rothaus)

In the last two XML cookbook entries, we talked about the technique of using the ReplaceWith method to perform an identity transform. While this technique may meet your needs, it can introduce a problem in your code commonly referred to as the “Halloween” problem. Let’s take a look at what the problem is, and how to solve it. (For ...

VB XML Cookbook, Recipe 4: Get Inner XML from the Nodes Property (Doug Rothaus)

Recipe 3 showed one way to work with mixed XML content using the XML Descendant axis property and the ReplaceWith method. This is one way to do an identity transform and we’ll look at another method in a later post. There is a key capability not mentioned in Recipe 3 that you will need for fully-functioning identity transforms. That is ...

VB XML Cookbook, Recipe 3: Identity Transforms (Doug Rothaus)

An identity transform in XSLT does just what the name implies: replace the identity of an element or attribute with a new identity.

Whenever a title is referred to within an article...

As is often the case with XML, you may need to reference sub...

VB XML Cookbook, Recipe 1: XML Transformations using XML Literals (Doug Rothaus)

I was working on a blog entry about replacing XSLT transforms with Visual Basic XML Literals. As the entry progressed, I noticed that it was really, really long. So, Avner Aharoni and I talked things over and we decided to break it up into multiple entries and start a series, much like the LINQ Cookbook that was started a few months back. ...

Channel 9 Interview: XML Properties and Enabling IntelliSense (Beth Massi)

Today I posted a Channel 9 interview with Avner Aharoni, a Program Manager on the Visual Basic Team. In this interview Avner shows us how to enable XML IntelliSense in Visual Basic using the XML to Schema Wizard. He also shows the differences between how IntelliSense works with axis properties on XDocument and XElement ...

Drawing Maps with Visual Basic (Scott Wisniewski)

If you find yourself looking for something to do with your awesome new copy of Visual Studio 2008, you should check out the December 2007 edition of MSDN magazine. It features an article, written by me, that provides a walk through on how to visualize data on a map using VB 9, WPF and LINQ. To give you a sneak preview of what the app ...
