Here is an article that shows you how to do this. It requires P/Invoke into the Windows API for most of the calls, however.

ShowWindow - p/invoked, of course.

Answer 3

    public void MaximizeForm(IntPtr handle)
    {
        Control c = Control.FromHandle(handle);
        Form c_form = c as Form;
        if (c_form != null)
        {
            if (c_form.InvokeRequired)
            {
                this.BeginInvoke(new MethodInvoker(delegate() { MaximizeForm(handle); }));
            }
            else
            {
                c_form.WindowState = FormWindowState.Maximized;
            }
        }
    }
