DisableDpiAwarenessAttribute Class


Allows WPF applications to disable dots per inch (dpi) awareness for all user interface elements.

Namespace:   System.Windows.Media
Assembly:  WindowsBase (in WindowsBase.dll)


[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false)]
public sealed class DisableDpiAwarenessAttribute : Attribute


Initializes a new instance of DisableDpiAwarenessAttribute.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

By default, WPF applications are dpi aware, which affects how user interface layout is calculated. However, an application can disable dpi awareness by adding the DisableDpiAwarenessAttribute to the application assembly.


It is not recommended that you set this attribute for your application, unless you need all user interface elements of your application to be non-dpi aware.
