Seems ScrollBy is not what you need. Sorry, I did not notice it in a hurry. Because it is working only with an Object, not with a Handle.
Anyhow, you can probably write Form1.ScrolBy(50,50); it scrolls the contents of a windowed control, look at the VCL Help: procedure ScrollBy(DeltaX, DeltaY: Integer);
Maybe its source will help you somehow:

procedure TWinControl.ScrollBy(DeltaX, DeltaY: Integer);
var
IsVisible: Boolean;
I: Integer;
Control: TControl;
begin
IsVisible := (FHandle <> 0) and IsWindowVisible(FHandle);
if IsVisible then ScrollWindow(FHandle, DeltaX, DeltaY, nil, nil);
for I := 0 to ControlCount - 1 do
begin
Control := Controls[I];
if not (Control is TWinControl) or (TWinControl(Control).FHandle = 0) then
begin
Inc(Control.FLeft, DeltaX);
Inc(Control.FTop, DeltaY);
end else
if not IsVisible then
with TWinControl(Control) do
SetWindowPos(FHandle, 0, FLeft + DeltaX, FTop + DeltaY,
FWidth, FHeight, SWP_NOZORDER + SWP_NOACTIVATE);
end;
Realign;
end;

Ok it seems like it all went a bit dead here.

It dont seems like it can be done the smart way then.

So what if i want to use the not cool version like:

pt:tpoint;
begin
getcursorpos(pt);

//Get the posistion of the scrollbar and click with mouse

setcursorpos(pt);
end;

any ideas?

Anybody have and idea on how this could be done?
The most comon way i know is getting cordinates to scroll arrow, then simulate mouse clicks. Maybe thats the only way?
