Exemples

L’exemple de code suivant illustre l’utilisation de EventWaitHandleRights lors de la création et l’utilisation des valeurs EventWaitHandleAccessRule objets.The following code example demonstrates the use of EventWaitHandleRights values when creating and using EventWaitHandleAccessRule objects. L’exemple crée un EventWaitHandleSecurity objet, ajoute des règles qui accordent et refusent divers droits à l’utilisateur actuel et affiche la paire de règles résultante.The example creates an EventWaitHandleSecurity object, adds rules that allow and deny various rights for the current user, and displays the resulting pair of rules. L’exemple permet de nouveaux droits de l’utilisateur actuel, puis affiche le résultat, indiquant que les nouveaux droits sont fusionnés avec le AccessControlType.Allow règle.The example then allows new rights for the current user and displays the result, showing that the new rights are merged with the existing AccessControlType.Allow rule.

Notes

Cet exemple ne s’attache pas l’objet de sécurité à un EventWaitHandle objet ; consultez EventWaitHandleSecurity, EventWaitHandle.GetAccessControl (méthode), et EventWaitHandle.SetAccessControl.This example does not attach the security object to an EventWaitHandle object; see EventWaitHandleSecurity, EventWaitHandle.GetAccessControl method, and EventWaitHandle.SetAccessControl.

Remarques

Utilisez le EventWaitHandleRights des droits d’énumération pour spécifier le contrôle d’accès lorsque vous créez EventWaitHandleAccessRule objets.Use the EventWaitHandleRights enumeration to specify access control rights when you create EventWaitHandleAccessRule objects. Pour appliquer des droits d’accès à un événement système nommé, ajoutez d’abord EventWaitHandleAccessRule des objets sur un EventWaitHandleSecurity de l’objet, puis attachez le EventWaitHandleSecurity objet à l’événement système nommé à l’aide la EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) constructeur ou la EventWaitHandle.SetAccessControl (méthode).To apply access rights to a named system event, first add EventWaitHandleAccessRule objects to an EventWaitHandleSecurity object, then attach the EventWaitHandleSecurity object to the named system event using the EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) constructor or the EventWaitHandle.SetAccessControl method.

Notes

Sécurité sur les objets de synchronisation n’est pas prise en charge pour Windows 98 ou Windows Millennium Edition.Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
