Silverlight 4: New features overview (Part 3) – Elevated Out-of-browser applications

Silverlight 4 enhances the out-of-browser feature introduced in previous version of the technology. Silverlight 3 added a feature to use application in Out-of-browser mode – install application shortcut to desktop or start menu, and launch it within application launcher (instead of the browser). Along with it, the application still was sandboxed application, with the same set of restrictions, like in browser. Silverlight 4 extends this feature and allows to relax some of the sandbox restrictions...

PDC09 Day 1 – Dynamics in C# 4

Switched to the Dynamics in C# 4 session.

Silverlight Tip: Enumerating embedded resources

Today I’ve got a “Call for Help” from one of Silverlight MVPs – Bill Reiss . The mail said: “I would like to enumerate all items that were marked as Content or Resource in the main XAP file. If I can’t do both I’d settle for one. Any sample code for this would be greatly appreciated. Bill”   I decided to help with embedded resources, because I did something like this in WPF. I’ve created sample application, which will display a list of resources in list box – from here it is very easy to use...

For my surprise I found that the property is an “object”, and assumed that it could behave as a ContentPresenter/ContentControl. After 5 minutes I had the client’s request solved: My code is very simple:...

WPF Quick Tip: How to get WPF Window client area size

This time my quick tip will be not about the Silverlight, but about WPF. When you have WPF window, the runtime size of it could be discovered by ActualWidth/ActualHeight properties. In most cases this is enough. But what about the case, when you need to perform some mathematical calculations based on the real size of client area? What is this client area? Well, the second question is really easy one – the client area is the area available to user defined UI (controls, panes, etc.): At the screenshot...
