    ' Signals wait start variable. If not initialized yet, initialize to ManualResetEvent.
    Private Sub SignalStart_()
        Dim vars As Variables
        Dim eventSignal As EventWaitHandle

        Try
            Call Dts.VariableDispenser.LockOneForWrite(WaitStart, vars)
            If vars(WaitStart).DataType = TypeCode.Object Then
                eventSignal = TryCast(vars(WaitStart).Value, EventWaitHandle)
                If eventSignal Is Nothing Then
                    ' Signal variable is not yet initialized.
                    eventSignal = New ManualResetEvent(True)
                    vars(SignalEnd).Value = eventSignal
                Else
                    ' Set signal.
                    Call eventSignal.Set()
                End If
            Else
                Throw New ApplicationException("Invalid variable type")
            End If
        Finally
            If Not vars Is Nothing Then
                Call vars.Unlock()
            End If
