Namespace: System.Diagnostics
Assembly: System (in system.dll)

'Declaration
Public Property EnableRaisingEvents As Boolean
'Usage
Dim instance As EventLog
Dim value As Boolean

value = instance.EnableRaisingEvents

instance.EnableRaisingEvents = value
/** @property */
public boolean get_EnableRaisingEvents ()

/** @property */
public void set_EnableRaisingEvents (boolean value)

public function get EnableRaisingEvents () : boolean

public function set EnableRaisingEvents (value : boolean)

Property Value

true if the EventLog receives notification when an entry is written to the log; otherwise, false.

The EnableRaisingEvents property determines whether the EventLog raises events when entries are written to the log. When the property is true, components receiving the EntryWritten event will receive notification any time an entry is written to the log specified in the Log property. If EnableRaisingEvents is false, no events are raised.

The following example handles an EntryWritten event.
