ReplicationServer.EnumBusinessLogicHandlers Method

Returns the business logic handlers registered at the server.

Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

public ArrayList EnumBusinessLogicHandlers()

The EnumBusinessLogicHandlers method can only be called by members of the sysadmin fixed server role and members of the db_owner fixed database role.

Calling EnumBusinessLogicHandlers is equivalent to executing sp_enumcustomresolvers (Transact-SQL).

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
