Namespace: System.Windows.Interop
Assembly: System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public ReadOnly Property Settings As Settings

public Settings Settings { get; }

Property Value

Type: System.Windows.Interop.Settings
The "Settings" sub-object.

Remarks

The "Settings" sub-object contains APIs that specifically relate to aspects of the HTML DOM outside of the Silverlight content area (the area declared by the width and height in the initialization).

Examples

The following code example demonstrates how to use this property.

' The Host object, which represents the host Silverlight plug-in. 
Dim host As System.Windows.Interop.SilverlightHost = _
    Application.Current.Host

' The following code demonstrates how to use the Host object 
' to access other APIs in the System.Windows.Interop namespace. 

' The IsVersionSupported method. This method is useful when 
' you want to implement an upgrade experience in managed code. 
Dim isSupported As Boolean = host.IsVersionSupported("2.0.30908.0")

' Read-only properties of the Host object. 
Dim pluginBackground As System.Windows.Media.Color = host.Background
Dim loaded As Boolean = host.IsLoaded
Dim source As Uri = host.Source

' The Settings object, which represents Web browser settings. 
Dim settings As System.Windows.Interop.Settings = host.Settings

' Read/write properties of the Settings object. 
settings.EnableFrameRateCounter = True
settings.EnableRedrawRegions = True
settings.MaxFrameRate = 60

' Read-only properties of the Settings object. 
Dim windowless As Boolean = settings.Windowless
Dim htmlAccessEnabled As Boolean = settings.EnableHTMLAccess

' The Content object, which represents the plug-in display area. 
Dim content As System.Windows.Interop.Content = host.Content

' The read/write IsFullScreen property of the Content object. 
' See also the Content.FullScreenChanged event. 
Dim isFullScreen As Boolean = content.IsFullScreen

' Read-only properties of the Content object. These properties do 
' not contain meaningful values until after the Content.Resized 
' event occurs for the first time. 
Dim actualWidth As Double = content.ActualWidth
Dim actualHeight As Double = content.ActualHeight

// The Host object, which represents the host Silverlight plug-in.
System.Windows.Interop.SilverlightHost host = 
    Application.Current.Host;

// The following code demonstrates how to use the Host object
// to access other APIs in the System.Windows.Interop namespace.

// The IsVersionSupported method. This method is useful when
// you want to implement an upgrade experience in managed code.
bool isSupported = host.IsVersionSupported("2.0.30908.0");

// Read-only properties of the Host object.
System.Windows.Media.Color pluginBackground = host.Background;
bool loaded = host.IsLoaded;
Uri source = host.Source;

// The Settings object, which represents Web browser settings.
System.Windows.Interop.Settings settings = host.Settings;

// Read/write properties of the Settings object.
settings.EnableFrameRateCounter = true;
settings.EnableRedrawRegions = true;
settings.MaxFrameRate = 60;

// Read-only properties of the Settings object.
bool windowless = settings.Windowless;
bool htmlAccessEnabled = settings.EnableHTMLAccess;

// The Content object, which represents the plug-in display area.
System.Windows.Interop.Content content = host.Content;

// The read/write IsFullScreen property of the Content object.
// See also the Content.FullScreenChanged event.
bool isFullScreen = content.IsFullScreen;

// Read-only properties of the Content object. These properties do 
// not contain meaningful values until after the Content.Resized 
// event occurs for the first time. 
double actualWidth = content.ActualWidth;
double actualHeight = content.ActualHeight;
