SQL Server 2012

Returns the IDTSComponentEvents collection of existing events defined in the package that contains the Script task.

Namespace: Microsoft.SqlServer.Dts.Tasks.ScriptTask
Assembly: Microsoft.SqlServer.ScriptTask (in Microsoft.SqlServer.ScriptTask.dll)

Syntax

C++

JScript

public EventsObjectWrapper Events { get; }

Property Value

Type: Microsoft.SqlServer.Dts.Tasks.ScriptTask.EventsObjectWrapper
The IDTSComponentEvents collection of existing events defined in the package that contains the Script task.

Remarks

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

Examples

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
