Dave et al,

Thanks for your suggestions. You are probably wondering what I am trying to do. I have a form within another form. I was thinking about writing code so that the inner form would fill the client area of the outer form. It just dawned on me that I can set the WindowState of the inner form to 2 - Maximized, and it will fill the client area of the outer form regardless of size.
