Protected Overridable Sub OnError( _
   ByVal e As ErrorEventArgs _
) 

'Usage
 
Dim instance As ComponentBase
Dim e As ErrorEventArgs
 
instance.OnError(e)

protected virtual void OnError( 
   ErrorEventArgs e
)

protected: virtual void OnError( 
   ErrorEventArgs* e
) 

protected:
virtual void OnError( 
   ErrorEventArgs^ e
) 

Parameters

e

A ErrorEventArgs object that contains the exception.

OnError allows derived classes to handle the Error event without attaching a delegate, but marshaling is not provided. This is the preferred technique for handling the event in a derived class.

Note to Inheritors: When overriding OnError in a derived class, be sure to call the base class OnError method, so that registered delegates receive the event.

See the SynchronizingObject property for information on updating UI controls in your event handler.
