En el ejemplo de código siguiente se escribe una entrada de evento informativo y, a continuación, se reutiliza para EventInstance escribir una entrada para un evento de advertencia en un registro de eventos existente. El texto del mensaje de evento se especifica mediante un identificador de recurso en un archivo de recursos de mensaje. En el ejemplo de código se supone que el archivo de recursos del mensaje correspondiente se ha registrado para el origen.

// Ensure that the source has already been registered using
// EventLogInstaller or EventLog.CreateEventSource.

   EventInstance ^ myEvent = gcnew EventInstance( UpdateCycleCompleteMsgId,0 );

   // Write the event to the event log using the registered source.
   EventLog::WriteEvent( sourceName, myEvent, 0 );

   // Reuse the event data instance for another event entry.
   // Set the entry category and message identifiers for
   // the appropriate resource identifiers in the resource files
   // for the registered source.  Set the event type to Warning.
   myEvent->CategoryId = RefreshCategoryMsgId;
   myEvent->EntryType = EventLogEntryType::Warning;

En el ejemplo de código se usa el siguiente archivo de texto de mensaje, integrado en la biblioteca de recursos EventLogMsgs.dll. Un archivo de texto de mensaje es el origen desde el que se crea el archivo de recursos del mensaje. El archivo de texto del mensaje define los identificadores de recursos y el texto de la categoría, el mensaje de evento y las cadenas de inserción de parámetros.

Para escribir una entrada informativa en un registro de eventos, inicialice y EventInstance pásela al WriteEvent método . Establezca en instanceId el identificador de recurso del mensaje de evento en la propiedad correspondiente MessageResourceFile para el origen. Establezca en categoryId un valor de categoría numérico o el identificador de recurso de la categoría de evento en la CategoryResourceFile propiedad del origen; establezca en categoryId cero para ninguna categoría de evento. La EntryType propiedad de la nueva instancia se establece Information en de forma predeterminada.

El Visor de eventos usa los identificadores de recursos para mostrar las cadenas correspondientes de los archivos de recursos localizados para el origen. Debe registrar el origen con los archivos de recursos correspondientes para poder escribir eventos mediante identificadores de recursos.
