DirectDraw Security
Use DirectDraw with caution in environments that require high security.
DirectDraw exists to enable high-performance multimedia applications. It does this by providing applications with the most direct path possible to the 2-D graphics hardware on a system.
DirectDraw applications can take control of the screen by putting themselves into full-screen exclusive mode. As long as the application remains open it can retain complete control of the entire display.
You should always use secure coding techniques while working with DirectDraw. For more information about Windows CE security services, see Enhancing the Security of a Device.
