VC++窗体震动【抖动】例子，使用一个窗口震动功能类：窗体震动例程。作者：徐景周。在对按钮初始化时，自动为按钮属性添加自画属性(OWNERDRAW) 　　dx=5; // 横坐标震动位移 　　dy=5; // 纵坐标震动位移 　　SetDialogBkColor(RGB(160,180,220),RGB(0,0,0));设置对话框背景和文本颜色。 　　m_bShake=false; //初始置停止震动标志为假，既震动 　　m_iTotal=1; //总计数值，到一定时间不再震动窗体 　　注：此程序只能运行一次，用互斥量来判断程序是否已运行

说明：  Background Given a set of rectangles {R1, R2, …, Rn}, compute the area of their common intersection. i.e., Area(R1∩R2∩…∩Rn) The edges of the rectangles R1, R2, …, Rn, are either vertical or horizontal lines. For example, the intersection of 4 rectangles, R1, R2, R3, and R4, in the following figure is the shaded rectangle. Input The input contains (N + 1) lines. The first line specifies the number of rectangles N, where 1 < N < 1000. Since the sides of the rectangles are parallel to the x-axis and y-axis, each rectangle is bounded by the lines x = x1, x = x2, y = y1 and y = y2 and each subsequent line of the input file thus specifies one rectangle in the following format: x1 x2 y1 y2 such that 0 <= x1 < x2 <= 10000 and 0 <= y1 < y2 <= 10000, and x1, x2, y1 and y2 are integers. Output The output file contains the area of the intersection of all the rectangles.

应用背景CodeForge网站最新公布了2015年9月“CodeForge最常用编程语言”排行榜。此排行榜清楚的反映了截止2015年9月各种编程语言在世界范围的流行程度，可为所有从事软、硬件开发的专业人员以及其他业内人士提供参考。需要说明的是，本排行榜所统计的数据，全部来源于www.codeforge.cn和www.codeforge.com 网站120多万注册用户的实际访问数据，具有非常高的真实性与实时性，有很大的参考价值。关键技术对比CodeForge 2015年6月份发布的最常用语言排行榜可以看出，入选前20名的语言没有发生变化。除了JSP与Tcl/Tk以及Fortran与Python的位置互换以外，其他20个语言的相对顺序没有发生变化，只是各自所占的比例有微小的变化。 从上图可以看出，C++仍然以超过四分之一的比例，高居榜首，达到27.69%，与上期所占比例相同。C++效率高，并且有很多成熟的网络通信的库，被广泛的应用于游戏开发、科学计算、网络软件、分布式应用、操作系统、驱动程序、移动设备、嵌入式系统以及教育

一个利用Auxiliary Particle Filter 的例子,来源于Gordon的Tutorial On Particle Filter. 该程序实现了此例中的辅助粒子滤波器的算法.RMS接近文章中的结果.(An example of the use of Auxiliary Particle Filter, from Gordon' s Tutorial On Particle Filter. This program implements in this case, the auxiliary particle filter algorithm. RMS close to the article in the results.)

主要介绍了等精度频率测量原理，该原理具有在整个测试频段内保持高精度频率 测量的优点 同时在该原理基础上，采用了Verilog HDL语言设计了高速的等精度测频 模块，并且利用EDA开发平台QUARTUS11 3 .0对CPLD芯片进行写人，实现了计数等 主要逻辑功能 还使用C语言设计了该等精度频率计的主控程序以提高测量精度。本设 计实现了对频率变化范围较大的信号进行频率测量，能够满足高速度、高精度的测频要 求。-Introduced, such as the accuracy of frequency measurement principle, the principle has in the entire test frequency to maintain the advantages of high precision frequency measurement at the same time the basis of the principle of using the Verilog HDL language, such as the design of a high-speed precision frequency measurement module, and use of EDA Development platform QUARTUS11 3 .0 on CPLD chip to write, and achieved a count of the main logic function, such as the use of C language is also designed such precision the frequency of control procedures to enhance measurement accuracy. This design achieved a wide range of frequency changes in signal frequency measurement, to meet the high-speed, high precision frequency measurement requirements.
