“Hilo” is a series of articles and sample applications that show how you can program for Windows 7 using Visual Studio 2010 and Visual C++. The end goal of this series is to enable developers to create high performance client applications that are responsive and attractive. Hilo provides both source code and the written guidance that will help you design and develop compelling, touch-enabled Windows applications of your own.
A series of articles are now on MSDN that describe the design and implementation of a set of touch-enabled Windows applications that allow you to browse, select, and work with photos and images. The articles cover key Windows 7 technologies, describe how they are used together to create a compelling user experience, and detail the design and implementation of the applications themselves. You can find the Hilo articles on the MSDN page Hilo: Developing C++ Applications for Windows 7 and you can find the Hilo sample code on the Hilo Code Gallery page. The first article provides an overview of Hilo and describes the goals of the articles and sample applications in the series and the rest go into details of the design and coding practices used throughout the release.
The Hilo article series, along with the sample application source code, are intended to jumpstart your development and show you how to take advantage of key Windows capabilities in your own.
