How to get visible MDI client area?

Hello!
Does anybody know how to get REALLY visible MDI client area?
ClientRectangle (even without scrollbars) is greater than its visible
part - it includes borders (checked). Not saying about StatusBar that
can visible or not. Framework knows this visible rectangle because it
adds scrollbars as soon as any child moves out of this rectangle.

I've found the solution:

private void FillActiveChildFormToClient()
{
Form child = this.ActiveMdiChild;
Rectangle mdiClientArea = Rectangle.Empty;
foreach(Control c in this.Controls)
{
if(c is MdiClient)
mdiClientArea = c.ClientRectangle;
}
child.Bounds = mdiClientArea;
}
