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