/// <returns>
/// The horizontal and vertical scroll percentages.

///--------------------------------------------------------------------
private double[] GetScrollPercentages(AutomationElement targetControl)
{
    if (targetControl == null)
    {
        throw new ArgumentNullException(
            "AutomationElement argument cannot be null.");
    }

    double[] percentage = new double[2];

    percentage[0] =
        (double)targetControl.GetCurrentPropertyValue(
        ScrollPattern.HorizontalScrollPercentProperty);

    percentage[1] =
         (double)targetControl.GetCurrentPropertyValue(
         ScrollPattern.VerticalScrollPercentProperty);

    return percentage;
