   ByVal e As LineInteractiveEventArgs _
)

Dim e As LineInteractiveEventArgs
 
instance.OnInteractiveMagnifyGlass(e)

protected:
virtual void OnInteractiveMagnifyGlass( 
   LineInteractiveEventArgs^ e
) 

Parameters

e

A LineInteractiveEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnInteractiveMagnifyGlass 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 OnInteractiveMagnifyGlass in a derived class, be sure to call the base class's OnInteractiveMagnifyGlass method so that registered delegates receive the event.
