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...

In Silverlight 4 we got new class, called PrintDocument which is a part of “System.Windows.Printing” namespace. This class provides a number of events, which helps to control the printing job: StartPrint – occurs right after printer selection dialog successfully returns, prior the first page print PrintPage – occurs...

PDC09 Day 1 – Dynamics in C# 4

Switched to the Dynamics in C# 4 session. This session hall is not full at all… I’d rather say it is pretty empty… Probably this session is for real technology geeks like me :)   Did you know, that you cold create your own dynamic object by deriving from DynamicObject base class? class Program { static void Main( string [] args) { dynamic d = new myDynamic (); Console .WriteLine(d++); } } class myDynamic : DynamicObject { public override bool TryUnaryOperation( UnaryOperationBinder binder, out...

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...

Silverlight Quick Tip: ChildWindow Title Customization

Today I discovered nice feature of ChildWindow control in Silverlight 3. I was at client’s location and been asked about the ChildWindow title customization with an icon. I had to admit, that I never tried to put something different than text and immediately looked at the type of Title property. 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...

Silverlight Quick Tip: Dynamically Updating Class Fields/Properties

In previous post ( here ) I blogged about displaying values of class/control in runtime and displaying them in Visual Studio - like property window. Today I’ll show how to push them back to the class instance. In previous post I’ve stored values in “ObservableCollection<FieldsPropertiesData>” for easy databinding and connected this ListBox control. In order to get user input I’ve created TwoWay databinding in DataTemplate – here is updated data template: < Style TargetType ="local:FiledPropertyData">...

Silverlight Quick Tip: Dynamically Displaying Class Fields/Properties

In one of my projects I had to create something like Visual Studio property window, for data set of different controls/data classes. Those controls/classes are still under development and I needed the way to display/change values of those properties dynamically without even knowing what is inside. For the simple case, let’s assume the following class which holds the data: public class SampleData { public SampleData() { BooleanProperty = false ; } public string StringProperty { get ; set ; } public...
