How to scroll a Scrollbox without the scrollbars being visible

using Delphi 6 pro and WinXP,
How do I scroll a scrollbox when the scrollbars are not visible, as in code?
I do not want the scrollbars displayed yet I want to be able to scroll the
scrollbox.
What happens is when the scrollbars are visible, changing their Position
properties scolls the scrollbox like normal, but when I set the scrollbar's
Visible property to False, changing the Position property does nothing at
all.
Can anyone help?
Thanks,

If you mean a TMemo, you can use Windows messages to scroll it up and
down.

TWinControl.ScrollBy seems like a good place to start.

OP gone AWOL

Why a scrollbox without scrollbars? Won't a panel do?

without the bars you won't get some user wheelmouse etc actions
or other scrolling actions,  they act wrt the bars not the box

cat.skin:=false;

put a scrollbox inside a panel sized so the bars don't show
make the panel borderstyle single, so it looks like a scrollbox

scrollbox.VertScrollBar.Position:=y;

you may also need the autoscroll property, to force the bars

be aware scrollboxes are not a virtual  screen
not an infinite viewplane
not a complete window manager, mostly useful
