Rounded form:
[DllImport("user32.dll")]
static extern int SetWindowRgn(IntPtr hWnd, IntPtr hRgn, bool bRedraw);
[DllImport("gdi32.dll")]
static extern IntPtr CreateRoundRectRgn(int x1, int y1, int x2, int y2,int cx, int cy);
You can use the TransparencyKey property on a Windows form to achieve the same effect.
You can also use the Region property of a Windows form to change the shape of the client area.

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
