?In this video we talk with Matthew Scott, a developer on the Word team who takes us through the design and development of the Word 2007 Content Control Toolkit, an application that natively reads and writes Word documents saved in the Open XML file format. This application has been released to the developer community on Codeplex as an open source project, with full C# source code. The content control tookit is a real-world example of working with the new Office Open XML file formats via the new System.IO.Packaging API in the .NET 3.0 framework. Its also a very handy tool for developers, providing the ability to map content controls to custom XML nodes through a simple drag&drop interface. Matt explains the architecture of the tool, shows how to use it, and then goes through some of the source code to demonstrate various best practices for Open XMLLinks:Project homepage Open XML Developer GroupBrian Joness blogWord team blogDownload the VideoWatch the Video
