Declaration
function Seek(Page : TIEIOSeekDestination) : integer;
Description
When 
DisplayMode is mdSingle then seek sets 
VisibleFrame to display the first/previous/next/last image.
Otherwise it sets 
SelectedImage to move the selection to the first/previous/next/last image.
Returns the new page index.
Note:
◼SelectSeek and Seek are similar and can often achieve the same task. 
SelectSeek is used to handle movement within the control and select frames appropriate. Seek is used just to display a specific frame.

OnSelectionChanging event will occur when using Seek (Result will be -1 if cancelled)
