A ServerEvents object that represents the server events.

Osservazioni

Testo aggiornato:

The Events property points to a ServerEvents object that controls the subscription to server events for the application to handle. Use the ServerEventSet object to create a variable that contains a specified set of server events, such as the CreateDatabase event. The server can then subscribe to the events by calling one of the SubscribeToEvents overloads. The StartEvents method then starts the server that is receiving events.

Questo spazio dei nomi, classe o membro è supportato solo nella versione 2.0 di Microsoft .NET Framework.

Esempio

'Create an event handler subroutine that runs when a table is created.
Private Sub MyCreateEventHandler(ByVal sender As Object, ByVal e As ServerEventArgs)
    Console.WriteLine("A table has just been added to the AdventureWorks database.")
End Sub
'Create an event handler subroutine that runs when a table is deleted.
Private Sub MyDropEventHandler(ByVal sender As Object, ByVal e As ServerEventArgs)
    Console.WriteLine("A table has just been dropped from the AdventureWorks database.")
End Sub
Sub Main()
    'Connect to the local, default instance of SQL Server.
    Dim srv As Server
    srv = New Server
    'Reference the AdventureWorks database.
    Dim db As Database
    db = srv.Databases("AdventureWorks")
    'Create a database event set that contains the CreateTable event only.
    Dim databaseCreateEventSet As New DatabaseEventSet
    databaseCreateEventSet.CreateTable = True
    'Create a server event handler and set it to the first event handler subroutine.
    Dim serverCreateEventHandler As ServerEventHandler
    serverCreateEventHandler = New ServerEventHandler(AddressOf MyCreateEventHandler)
    'Subscribe to the first server event handler when a CreateTable event occurs.
    db.Events.SubscribeToEvents(databaseCreateEventSet, serverCreateEventHandler)
    'Create a database event set that contains the DropTable event only.
    Dim databaseDropEventSet As New DatabaseEventSet
    databaseDropEventSet.DropTable = True
    'Create a server event handler and set it to the second event handler subroutine.
    Dim serverDropEventHandler As ServerEventHandler
    serverDropEventHandler = New ServerEventHandler(AddressOf MyDropEventHandler)
    'Subscribe to the second server event handler when a DropTable event occurs.
    db.Events.SubscribeToEvents(databaseDropEventSet, serverDropEventHandler)
    'Start event handling.
    db.Events.StartEvents()
    'Create a table on the database.
    Dim tb As Table
    tb = New Table(db, "Test_Table")
    Dim mycol1 As Column
    mycol1 = New Column(tb, "Name", DataType.NChar(50))
    mycol1.Collation = "Latin1_General_CI_AS"
    mycol1.Nullable = True
    tb.Columns.Add(mycol1)
    tb.Create()
    'Remove the table.
    tb.Drop()
    'Wait until the events have occured.
    Dim x As Integer
    Dim y As Integer
    For x = 1 To 1000000000
        y = x * 2
    Next
    'Stop event handling.
    db.Events.StopEvents()
