Since the first release of Silverlight, the community has been patiently waiting for a version of Silverlight which would allow us to capture video from a user’s webcam, as well as audio from their microphone. This past month at PDC 09, our wait was over with the release of Silverlight 4 Beta 1.

In this article we will explore the ways in which Silverlight can interact with a webcam, as well as the powerful results one can produce by combining live video with pixel shaders, video brushes as well as WriteableBitmaps.

Getting Started

The initial code for the combo box was obtained by reflecting (http://www.red-gate.com/products/reflector/) on the Silverlight ListBox control. This provided the initial xaml and C# for the dropdown portion of the combo box, so we renamed the controls from ListBoxItem to ComboBoxItem and ListBox to ComboBox.

Introduction

Silverlight is one of the major new technologies from Microsoft and will potentially have a huge impact on the Microsoft development community. Developers are rapidly looking to Silverlight to solve major challenges and limitations as posed by existing technologies (such as Windows Forms and ASP.NET). WPF uptake has been lukewarm at best, however the similarities it has with Silverlight could very well give it the kick it needs.

1. Introduction

I recently found myself in the following situation. My boss came to me and asked me: “Dude, we have a big Silverlight project, performing a great number of CRUD operations. We need to find a unified way of showing Modal Dialogs in a MVVM manner, without using any code in the View. The logic of showing dialogs must reside in the ViewModel, not in the code-behind. Also do you remember our previous WinForms projects? There are several pretty useful classes, such as BindingSource and DataRowView, implementing BeginEdit, EndEdit and CancelEdit functionality out of the box.
