/// <param name="targetControl">
/// The automation element of interest.
/// </param>
/// <returns>
/// The horizontal and vertical view sizes.
/// </returns>
///--------------------------------------------------------------------
private double[] GetViewSizes(AutomationElement targetControl)
{
    if (targetControl == null)
    {
        throw new ArgumentNullException(
            "AutomationElement argument cannot be null.");
    }

    double[] viewSizes = new double[2];

    viewSizes[0] =
        (double)targetControl.GetCurrentPropertyValue(
        ScrollPattern.HorizontalViewSizeProperty);

    viewSizes[1] =
         (double)targetControl.GetCurrentPropertyValue(
         ScrollPattern.VerticalViewSizeProperty);
