autoscroll bars and mdi forms

hello

ive got a MDI form(with borders) and am opening a childform inside,
that shows without any borders and needs to be sized exactly to the
visible area in the mdi form, inside the borders.

My problems are, when t use the mdiform. clientrectangle.size for
width and height, it always seems to make the child form a little too
big,

and also

even if i size the childform manually with the exact pixel size the
auto scroll bars on the mdi form always appear. I cant get the auto
scroll bars to not appear.

I have set the autoscroll mdi property to false, but they keep
appearing

how can i stop the autoscroll bars coming up ?


thanks for any help
