显示进度条的VB异步下载实例，在获取下载任务后，用ListView列表显示当前任务，使用了Subclass.ocx控件的下载程序示例，本实例虽是一个下载程序，但可学习到不少实用的知识技巧，比如网络下载的实现、ListView控件的使用、进度条的实现等。

说明：  利用大数据处理框架+实时内存计算处理海量数据,再利用协同过滤算法等实现电商系统对于用户购买及推荐类似商品的精准定位(Using large data processing framework + real-time memory computing to process massive data, and then using collaborative filtering algorithm to achieve accurate positioning of e-commerce system for users to purchase and recommend similar goods)

说明：  本书采用大量图片，通过详细的分步讲解，以直观、易懂的方式展现了7个数据结构和26个基础算法的基本原理。第1章介绍了链表、数组、栈等7个数据结构；从第2章到第7章，分别介绍了和排序、查找、图论、安全、聚类等相关的26个基础算法，内容涉及冒泡排序、二分查找、广度优先搜索、哈希函数、迪菲 - 赫尔曼密钥交换、k-means 算法等。 本书没有枯燥的理论和复杂的公式，而是通过大量的步骤图帮助读者加深对数据结构原理和算法执行过程的理解，便于学习和记忆。将本书作为算法入门的第一步，是非常不错的选择。(This book uses a large number of pictures, through detailed step-by-step explanation, in an intuitive and easy to understand way to show the basic principles of 7 data structures and 26 basic algorithms. Chapter 1 introduces seven data structures such as linked list, array and stack; from Chapter 2 to Chapter 7, 26 basic algorithms related to sorting, searching, graph theory, security and clustering are introduced respectively, including bubble sorting, binary searching, breadth first search, hash function, Diffie Herman key exchange, K-means algorithm, etc. This book does not have boring theory and complex formula, but through a large number of step diagrams to help readers deepen the understanding of data structure principle and algorithm execution process, easy to learn and remember. This book as the first step of the algorithm, is a very good choice.)

说明：  计算反射谱和透射谱，对于做多层膜模拟的有一定用处(The calculation of reflection spectrum and transmission spectrum is useful for multilayer film simulation)

说明：  通过编程实现模糊神经控制，在运行后或绘制出误差图、隶属函数变化图等(The fuzzy neural control is realized by programming, and the error diagram and membership function change diagram are drawn after operation)

此源码是简单Pascal编译器实现代码，采用工具LEX和YACC实现-this source is simple Pascal compiler for code using tools LEX and YACC

基于遗传算法的选址MATLAB代码，案例分析(Location based MATLAB code based on genetic algorithm)

该程序可以用于工业控制，特别是工业控制计算机需要自动关机的地方-the procedure can be used for industrial control, especially in the industrial control computer needs of local automatic shutdown

说明：  该程序实现的是雷达压制干扰，初学者可以下载后在matlab跑跑，结合论文学习(The program is to suppress radar jamming, beginners can download and run in matlab, combined with paper learning.)

java写的simplepong,能够实现所有基本功能,不妨下下来学习一下!-simplepong wrote to the realization of all the basic functions, it may be down under study how!
