EventLogWatcher(EventLogQuery, EventBookmark)

Initializes a new instance of the EventLogWatcher class by specifying an event query and a bookmark that is used as starting position for the query.

public:
 EventLogWatcher(System::Diagnostics::Eventing::Reader::EventLogQuery ^ eventQuery, System::Diagnostics::Eventing::Reader::EventBookmark ^ bookmark);

public EventLogWatcher (System.Diagnostics.Eventing.Reader.EventLogQuery eventQuery, System.Diagnostics.Eventing.Reader.EventBookmark bookmark);

new System.Diagnostics.Eventing.Reader.EventLogWatcher : System.Diagnostics.Eventing.Reader.EventLogQuery * System.Diagnostics.Eventing.Reader.EventBookmark -> System.Diagnostics.Eventing.Reader.EventLogWatcher

Public Sub New (eventQuery As EventLogQuery, bookmark As EventBookmark)

Parameters

eventQuery

EventLogQuery

Specifies a query for the event subscription. When an event is logged that matches the criteria expressed in the query, then the EventRecordWritten event is raised.

bookmark

Initializes a new instance of the EventLogWatcher class by specifying an event query, a bookmark that is used as starting position for the query, and a Boolean value that determines whether to read the events that already exist in the event log.

public:
 EventLogWatcher(System::Diagnostics::Eventing::Reader::EventLogQuery ^ eventQuery, System::Diagnostics::Eventing::Reader::EventBookmark ^ bookmark, bool readExistingEvents);

public EventLogWatcher (System.Diagnostics.Eventing.Reader.EventLogQuery eventQuery, System.Diagnostics.Eventing.Reader.EventBookmark bookmark, bool readExistingEvents);

new System.Diagnostics.Eventing.Reader.EventLogWatcher : System.Diagnostics.Eventing.Reader.EventLogQuery * System.Diagnostics.Eventing.Reader.EventBookmark * bool -> System.Diagnostics.Eventing.Reader.EventLogWatcher

Public Sub New (eventQuery As EventLogQuery, bookmark As EventBookmark, readExistingEvents As Boolean)

Parameters

eventQuery

EventLogQuery

Specifies a query for the event subscription. When an event is logged that matches the criteria expressed in the query, then the EventRecordWritten event is raised.

bookmark

EventBookmark

The bookmark (placeholder) used as a starting position in the event log or stream of events. Only events that have been logged after the bookmark event will be returned by the query.
