VC++获取网卡MAC、硬盘序列号、CPU ID、BIOS编号,是个文档，用来学习，需要的话代码移植下也比较简单(VC++ Gets NIC MAC, hard drive serial number, CPU ID, BIOS serial number, is a document used to study under the required code migration is relatively simple)

VC的难点解译和提出的解决问题，会很有用(VC difficulty of interpretation, and proposed to solve the problem, would be useful)

vc——创建带有图标的菜单BitmapMenu(vc- create a menu with icons BitmapMenu)

电梯算法 在一座10层高的宾馆的大厅内，有4部由一个控制器控制电梯。乘客随时在各层选择要去的楼层。要求： 1、设计一个电梯算法，最优地满足乘客的要求（候时最小）。 2、区分电梯的状态，如空运行、载人运行、超重、当前有故障等（可人工设置）。 3、在电梯全部无人乘做时，电梯要按一定条件（可人工设置）分布在各层。 4、保存一个星期内的各电梯的运行记录。 (Elevator algorithm in a 10-storey hotel in the hall, there are four elevators controlled by a controller. Passengers at any time choose to go to the floor on each floor. Requirements: 1, design an elevator algorithm, best meet the requirements of passengers (minimum waiting time). 2, the distinction between the state of the elevator, such as the air running, manned operation, overweight, current faulty, etc. (manual setting). 3, no ride in the elevator all to do, the elevator according to certain conditions (which can be manually set) distributed in layers. 4, save a week running record of each elevator.)

这是我图形学课程的作业，利用OPENGL和VC++开发，画的是一个动态场景，有光照，阴影等效果，可旋转。(This is my operating graphics programs, use of OPENGL and VC++ development is a dynamic art scene, with light, shadows and other effects, may be rotating.)

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.)

pic_eps.bat 批处理文件 可以很方便的将任意格式的图片转为eps格式(pic_eps.bat batch file can easily be converted to any format image eps format)

电子海图程序源代码，可以对S57格式文件进行解析，希望高手能将显示做出来(Electronic Chart source code, you can format documents on S57 resolve, I hope you can show up to do)

采用 c++编写的互补误差函数erfc，直接调用即可计算互补误差函数值(C++ prepared using the complementary error function erfc, direct calls to the complementary error function value is calculated)
