COM技术内幕的源代码，都已经编译测试，个人觉得不错，特来分享(COM-INSIDE CODE,Sharing it)

输入并存储一个由26个英文字母（不分大小写）组成的字符串，再输入一个英文字母，查找该字母在字符串中第一次出现的位置。 要求：分别采用以下方法实现 （1）使用字符数组（即char数组）存放字符串； （2）使用string变量存放字符串。(Enter and store a string consisting of 26 English letters (no case in case), and then enter an English letter to find the first place that the letter appears in the string. Requirements: the following methods are implemented)

跑马灯又叫走马灯、串马灯。由毛竹编织成马头，马尾，属于灯笼的一种。是传统特色手工艺品，亦是传统节日玩具之一。在过去，跑马灯一般在春节等喜庆的日子里才表演，由二十来位11—14岁小孩组成，边跳边唱，根据节奏快慢形成不同阵势，有喜庆、丁财两旺、五谷丰登的寓意。跑马灯属系在身上糊上颜色鲜艳的纸，如今已由丝绸取代(Entertaining diversions also called regimes, string of lantern. Woven from bamboo horsehead, horsetail, belongs to a kind of lanterns. Is a traditional arts and crafts, and it is one of the traditional holiday toys. In the past, entertaining diversions generally festive days before performance, such as the Spring Festival is composed of twenty to 11-14 years old children, dance while singing, according to different rhythm form appearance, have a festival, Ding Cai flourish, the meaning of good harvest. Entertaining diversions on the body belong to paste on the colored paper, is now replaced by the silk)

针对传统的算法如遗传算法、粒子群算法等在TSP问题上求解精确性和求解规模上都还有一定的不足，本文提出了一种基于动态规划思想的粒子群优化算法。该算法用动态规划的方法实现粒子间的信息交互和粒子的进化，并且将粒子群中的粒子按无标度信息指导网络拓扑图的方式进行连接。仿真结果表明该方法能有效地减小误差率，提高解的精确，同时还保持了较低的计算复杂度，具有良好的稳健性。(TSP problem solving for the traditional algorithms such as genetic algorithms, particle swarm optimization accuracy and solving the scale, there is a certain lack of a dynamic programming algorithm-based particle swarm optimization algorithm. The algorithm using dynamic programming method to achieve the evolution of information exchange between the particles and the particles, and particle swarm particle scale-free information guide network topology map to connect. The simulation results show that this method can effectively reduce the error rate and improve the solution precision, while maintaining a low computational complexity, good soundness.)

数据结构中链式队列和堆栈的循环用法，非常有用(Queue data structure in the chain and the cycle stack usage, very useful)

一个关于列表框控件自绘的小程序，点击某项会相应显示输入框或者组合框。(A small program on self-drawn list box control, the click of a corresponding input box or combo box.)

工业应用需要大量的电机。例如，电动机用于操纵工业机器人，电动汽车轮毂电机与电器火车。两种方法存在的控制永磁电机提供逆变器，每个电机的控制和连接在电机并行和驾驶他们的单个逆变器。第一种方法让实验装置复杂而昂贵的。的第二，因为又不允许独立控制每个电机两台电机的转子夹角的差异。因此，我们提出了一种新型的九开关逆变，可以独立控制两个三相负荷。本文介绍了结构九开关逆变器，由九个开关。的通过模拟验证，该逆变器的有效性和实验。
