Protected Overridable Sub OnInteractiveUserRectangle( _
   ByVal e As RasterViewerRectangleEventArgs _
) 

Visual Basic (Usage)	Copy Code
Dim instance As RasterImageViewer Dim e As RasterViewerRectangleEventArgs   instance.OnInteractiveUserRectangle(e)

protected virtual void OnInteractiveUserRectangle( 
   RasterViewerRectangleEventArgs e
)

protected:
virtual void OnInteractiveUserRectangle( 
   RasterViewerRectangleEventArgs^ e
) 

Parameters

e

A RasterViewerRectangleEventArgs object that contains the event data.

Raising an event invokes the event handler through a delegate. The OnInteractiveUserRectangle 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 OnInteractiveUserRectangle in a derived class, be sure to call the base class's OnInteractiveUserRectangle method so that registered delegates receive the event.

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
