一种利用硬盘序列号对自开发软件的简单且有效的加密注册方法，适用于发布量不大、尤其不公开发行的专用工程软件。主要目的：为使开发者的软件不被任意复制使用，用户每装一台机器都需要向开发者报知用户号并索取注册号。基本原理：将硬盘序列号做运算后做为用户号，开发者可利用科学型计算器，根据用户报知的用户号和只有自己知道的密钥直接算出注册码返回给用户；用户端不需注册机，开发者也不需解码器，且注册成功后Windows系统会自动保存，以后无需再注册，软件升级也无需重新注册。 所附VC源代码中有实现方法和详细注释。(A use of hard disk serial number from the development of software for simple and efficient encryption registration method is not applicable to the amount released, especially not publicly released a dedicated engineering software. The main purpose: to enable software developers to use not to be arbitrarily copied, each user needs to install a machine to developers informing the user number and request a registration number. Rationale: The hard disk serial number as user numbers do after the operation, developers can take advantage of the scientific calculator, directly calculated by the license is returned to the user based on the user notification of user numbers and only you know the key client without RI, developers also need a decoder, and after successful registration Windows system will automatically save the future without re-registration, software upgrades without having to re-register. There annexed VC source code implementation and detailed notes.)

实例 用Modeler搭建一个ALOHA协议仿真平台，进一步熟悉Modeler节点级和进程级的操作，深化三层建模机制。(进程->节点->网络) (Examples ALOHA protocol with Modeler to build a simulation platform to further familiarize Modeler node level and process-level operations, deepening three modeling mechanism. (Process-> Node-> Network))

基于directx 8.0的贪吃蛇程序，是一个课程设计写的，可以通过串口通信控制该程序，在没有串口的情况下也可以使用(Snake procedures based directx 8.0 is a program designed to write, through serial communication control the program, in the case of no serial port can also be used)

用DLL实现多语言包，可以进行本地化开发(DLL used to achieve multi-language package, can be localized development)

一个元器件管理的管理软件。主要体现在对数据增删改查方面，即对数据库的操作。使用的是ACCESS数据库，ADO方式连接。程序启动时弹出登陆界面。用户名admin，密码123456。不同的用户登陆之后界面也不一样。(An Element Manager System，Use Access Database for add,delete,update and query data.Use ado type connect Database.You can use user:admin,password:123456 login in.and different user have different functions.)
