/**
 * Description:This sample demonstrates setting the PageLayoutBean's FocusMap and using
 *    the IObjecyCopy object to overwrite the MapBean's Map object with a copy
 *    of the PageLayoutBean's FocusMap. The Map object has to copied because the
 *    MapBean and PageLayoutBean are unable to share the same ActiveView at
 *    the same time.
 *    The file chooser dialog allows users to search and
 *    select map documents, which are validated and loaded into the PageLayoutBean
 *    using the checkMxFile and loadMxFile methods. This triggers the OnPageLayoutReplaced
 *    event which loops through the Elements in the PageLayoutBean's GraphicsContainer
 *    finding MapFrame elements. The name of each MapFrame is set to the name of the Map
 *    in the MapFrame using the IElementProperties interface. A ComboBox is populated with
 *    all Map name's to allow users to change the FocusMap. The FindElementByName method is
 *    used to find the MapFrame containing the Map that is to become the FocusMap.<p/>
 *
 *    The PageLayoutBean's OnFocusMapChanged and OnAfterScreenDraw (when a new Map
 *    Document has been loaded into the PageLayoutBean) events use the IObjectCopy
 *    Copy and Overwrite methods to overwrite the MapBean's Map with a copy of the
 *    PageLayoutBean's FocusMap.
 *
 *    The PageLayoutBean and MapBean OnMouseDown event's use the TrackRectangle
 *    and Pan methods to zoomin and pan around either the PageLayoutBean's Page or
 *    the MapBean's Map. If the MapBean's display is redrawn due to a change in
 *    VisibleExtent, the OnAfterScreenDraw event is used set the Extent of the
 *    PageLayoutBean's FocusMap equal to that of the MapBean using the
 *    IDisplayTransformation interface.
