Exemples

The following sample of code for use inside a Script task demonstrates logging from the Script task by recording a value that represents the number of rows processed.

[Visual Basic]
Public Sub Main()

    Dim rowsProcessed As Integer = 100
    Dim emptyBytes(0) As Byte

    Try
        Dts.Log("Rows processed: " & rowsProcessed.ToString, _
            0, _
            emptyBytes)
        Dts.TaskResult = ScriptResults.Success
    Catch ex As Exception
        'An error occurred.
        Dts.Events.FireError(0, "Script Task Example", _
            ex.Message & ControlChars.CrLf & ex.StackTrace, _
            String.Empty, 0)
        Dts.TaskResult = ScriptResults.Failure
    End Try

End Sub
