備註

Use the Events property of the Dts object in Script task code to raise errors, warnings and information messages.

範例

The following sample of code for use inside a Script task demonstrates how to raise events from within the Script task. The example uses a native Windows API function to determine whether an Internet connection is available. If no connection is available, it raises an error. If a potentially volatile modem connection is in use, the example raises a warning. Otherwise, it returns an informational message that an Internet connection has been detected.

Private Declare Function InternetGetConnectedState Lib "wininet" _
    (ByRef dwFlags As Long, ByVal dwReserved As Long) As Long

Private Enum ConnectedStates
    LAN = &H2
    Modem = &H1
    Proxy = &H4
    Offline = &H20
    Configured = &H40
    RasInstalled = &H10
End Enum

Public Sub Main()

    Dim dwFlags As Long
    Dim connectedState As Long

    connectedState = InternetGetConnectedState(dwFlags, 0)

    If connectedState <> 0 Then
        If (dwFlags And ConnectedStates.Modem) = ConnectedStates.Modem Then
            Dts.Events.FireWarning(0, "Script Task Example", _
                "Volatile Internet connection detected.", String.Empty, 0)
        Else
            Dts.Events.FireInformation(0, "Script Task Example", _
                "Internet connection detected.", String.Empty, 0, False)
        End If
    Else
        ' If not connected to the Internet, raise an error.
        Dts.Events.FireError(0, "Script Task Example", _
            "Internet connection not available.", String.Empty, 0)
    End If

    Dts.TaskResult = ScriptResults.Success

End Sub
