By default, the form has a limited size title area to which the aero-glass effect is applied. I'd like to increase that area, not only at the title, but at the bottom and the sides of my form.

Use DwmExtendFrameIntoClientArea:
[StructLayout(LayoutKind.Sequential)]
struct MARGINS {
int Left;
int Right;
int Top;
int Bottom;
}
[DllImport("user32.dll")]
public static extern IntPtr DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS pMarInset);
Call DwmExtendFrameIntoClientArea with your form's Handle and a MARGINS structure. Just set Left, Right, Top and Bottom to the amount you want the respective borders extended by.
Oh, and set the BackColor of your form to Black. (Thanks, @HansPassant!)
Sorry if I got the extern syntax wrong. I haven't ever done this in C#...

Looks like what I'm looking for, but I just can't seem to make it work :x Could you please add a working example? – user1306322 May 06 '12 at 18:58

It isn't enough, you also have to draw it black: http://www.danielmoth.com/Blog/Vista-Glass-In-C.aspx – Hans Passant May 06 '12 at 19:03

@HansPassant since you linked to that website, could you please explaing what is `g` in `g.FillRectangle(blackBrush, 0, 0, this.ClientSize.Width, marg.Top);` and how do I use it correctly? Also I see white background instead of described black, is it ok? – user1306322 May 06 '12 at 19:15

That was a hint to @minitech to help him improve his answer :) – Hans Passant May 06 '12 at 19:18

@HansPassant: Thanks, I forgot that part :) Actually, any color except the default will work. – Ry- May 06 '12 at 19:19

@user1306322: Just set the `BackColor` of your form to `Black`, it has the same effect. Of course, then you'll want to put a `Panel` with the usual color back over top of it so that everything looks normal. – Ry- May 06 '12 at 19:19
