Inside an MDI form is a client area that hosts the mdi child forms. How do I find out how big that area is? The best I can come up with so far is finding the total size of the parent's potential client area (mdiparent.ClientRectangle) and then subtracting off the sizes of components like toolbars, etc that take away from the client area. Is there a better way?

There is no property on a form that gives you access to the MDI client window. But you can find it back like this:
From there, just use its Size property.
