EventLog.SynchronizingObject Property

Gets or sets the object used to marshal the event handler calls issued as a result of an EventLog entry written event.

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

public ISynchronizeInvoke SynchronizingObject { get; set; }
/** @property */
public ISynchronizeInvoke get_SynchronizingObject ()

/** @property */
public void set_SynchronizingObject (ISynchronizeInvoke value)

public function get SynchronizingObject () : ISynchronizeInvoke

public function set SynchronizingObject (value : ISynchronizeInvoke)

Property Value

The ISynchronizeInvoke used to marshal event-handler calls issued as a result of an EntryWritten event on the event log.

NoteNote

The HostProtectionAttribute attribute applied to this property has the following Resources property value: Synchronization. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

When SynchronizingObject is a null reference (Nothing in Visual Basic), methods handling the EntryWritten event are called on a thread from the system thread pool. For more information on system thread pools, see ThreadPool.

When the EntryWritten event is handled by a visual Windows Forms component, such as a button, accessing the component through the system thread pool might not work, or might result in an exception. Avoid this by setting SynchronizingObject to a Windows Forms component, which causes the methods handling the EntryWritten event to be called on the same thread on which the component was created.

If the EventLog is used inside Visual Studio 2005 in a Windows Forms designer, SynchronizingObject is automatically set to the control containing the EventLog. For example, if you place an EventLog on a designer for Form1 (which inherits from Form) the SynchronizingObject property of EventLog is set to the instance of Form1.
