Protected Overridable Sub OnUseDpiChanged( _
   ByVal e As EventArgs _
) 

Visual Basic (Usage)	Copy Code
Dim instance As RasterImageViewer Dim e As EventArgs   instance.OnUseDpiChanged(e)

protected virtual void OnUseDpiChanged( 
   EventArgs e
)

protected:
virtual void OnUseDpiChanged( 
   EventArgs^ e
) 

Parameters

e

An System.EventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnUseDpiChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnUseDpiChanged in a derived class, be sure to call the base class's OnUseDpiChanged method so that registered delegates receive the event.

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
