Valore proprietà
A Boolean value. If true, Web synchronization is used. If false, the default, a direct connection to the Publisher and Distributor is used to synchronize the subscription.
Osservazioni
The UseWebSynchronization property can only be retrieved by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.
The UseWebSynchronization property can only be set by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.
Retrieving the UseWebSynchronization property is equivalent to executing sp_helpmergepullsubscription.
Setting the UseWebSynchronization property is equivalent to executing sp_addmergepullsubscription_agent or sp_changemergepullsubscription.
The UseWebSynchronization property is availably only with instances of Microsoft SQL Server 2005.
This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.
