How do you get the TImageEnView horizontal or vertical scrollbar position? I can not seem to find a way to get this.

Hi Bill

Access to the scrollbar position is not available as a TImageEnView property but you can use ViewX and ViewY.

You should be able to use the Windows function GetScrollInfo to return the current position of the scrollbars.

Here is an example:

procedure TMDIChild.Button1Click(Sender: TObject);
var
  ScrInfo: TScrollInfo;
begin
  fillchar( ScrInfo, SizeOf( ScrInfo ), 0 );
  With ScrInfo do
  begin
    cbsize := SizeOf( ScrInfo );
    fmask  := SIF_ALL;
    GetScrollInfo( ImageEnView1.handle, SB_VERT, ScrInfo );
    ShowMessage( IntToStr( nPos ));
  end;
end;

Thanks Nigel,

I tried something like that but I must have messed it up somehow.
