Form width and length

Question:
My program has two MDI forms. I have an option that allows the user to tile them horizontally or vertically. How can I tell at runtime what the max form width and height are without setting the window's state to wsMaximized? I tried the screen.width and screen.height, but they don't take the Win95 taskbar into account.

Answer:
MDI child forms operate within the context of a "parent" form, so you can determine what the optimal maximized size would be by referring to the Parent.ClientHeight and Parent.ClientWidth from the child form. The ClientHeight and -Width properties define the space inside the borders of a form.
