在Windows2000中Ctrl-Alt-Delete组合键的处理如下： Winlogon初始化的时候，在系统中注册了CTRL+ALT+DEL Secure Attention Sequence(SAS)热键，并且在WinSta0 Windows 系统中创建三个桌面。 SAS热键的注册使得Winlogon成为第一个处理CTRL+ALT+DEL的进程，所以保证了没有其他应用程序能够处理这个热键。 在 Windows NT/Windows 2000/Windows XP中， WinSta0 是表示物理屏幕、鼠标和键盘的Windows系统对象的名字。Winlogon在WinSta0 Windows系统中创建了SAS窗口（窗口标题是"SAS Window"）和如下三个桌面。 Winlogon 桌面 应用程序 桌面 屏幕保护 桌面当用户按下Ctrl-Alt-Delete组合键时，Winlogon桌面上的SAS窗口收到它注册的系统热键消息(WM_HOTKEY) SAS Window窗口处理这个消息调用Graphical Identification and Authentication(GINA)动态连接库中的相关函数…… -Graphical Identification and Authentication(GINA)

一款接球游戏,游戏中使用DirectX 7，图形较为流畅，每秒高达50桢。具有较高的计算机人工智能.英文介绍：DX pong is a neat pong game that uses DirectX 7. I wrote it in just one day and the graphics are smooth - over 50 fps! There are sound FX too, but the best thing about the game is the computer AI. It doesn t simply chase the ball, it predicts the balls path even if it is going to bounce of several walls and moves accordingly. Clever AI doesn t mean it is impossible to beat - it means it acts like a human player making the game more fun. So - have fun!-DX pong is a neat pong game that uses DirectX 7.

The sequence-pair was proposed to represent a rectangle packing and a placement, and is used to place modules automatically in VLSI layout design. Several decoding methods of sequence-pair were proposed. However, encoding methods are not found except the original one called “gridding”.
