今天给大家带来使用文本文件作为数据源的 ComboBox中国城市三级联动的代码。 1.地区库更新非常方便，不会影响到其他功能（区划代码是唯一的）。 2.文本文件读取来速度很快。(n the past, I used VB6 to write an example of three-level linkage of ComboBox in Chinese cities, using MDB database. A few years ago, the code, the regional database is not the latest. Today we bring you the code of ComboBox, which uses text files as data sources, for three-level linkage of Chinese cities. 1. The regionalization library updates are very convenient and will not affect other functions (regionalization code is the only one). 2. Text files are read very fast.)

利用VC++编写的俄罗斯方块，大家可以看看玩玩啊(Tetris with VC++)

说明：  采用Visio Studio编译生成动态链接库，嵌入Psim进行仿真。仿真模型提供了半桥谐振变换器的数模混合仿真，有动态链接库实现PWM的分配。(Visio Studio is used to compile and generate dynamic link libraries, which are embedded in Psim for simulation. The simulation model provides digital-analog hybrid simulation of half-bridge resonant converter, with dynamic link library to realize PWM allocation.)

ELM的C语言版本，黄广斌教授的研究成果(The C version of ELM, which is proposed by Prof. Guangbin Huang.)

WPF控件与java的通信，JAVA加载WPF控件(The main ideas of Java and .NET code integration described in [4] where I showed an example of embedding .NET GUI components into Java interface. For anybody who is not familiar with Object-Oriented JNI for .NET, I recommend reading this article first. Description of Windows Presentation Foundation (WPF) can be found in MSDN, special manuals and is also not discussed in this article. WPF Module used in my example (without sources) was borrowed from [1]. Here I set out only with the task of embedding WMF Component into Java GUI. )

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)

DirectX 的 doc 文件----------------(DirectX, doc file)

可以根据输入的生成多项式计算CRC16的余式表，并输出到TXT文件中打开。附赠CRC16的查表程序和直接计算程序，供验证用。使用这段程序，可以完美解决CRC16的编程问题，CRC32以及CRC8也可以参考使用。(CRC16 remainder table according to the generator polynomial of the input and output to a TXT file to open. Comes with a CRC16 table look-up procedure and a direct calculation program, for verification purposes. This program can be the perfect solution the CRC16 programming problem, the CRC32 and CRC8 also be of use.)
