实现windows和linux之间的通信 或者 window间通信 linux间通信(Communication between windows and Linux or communication between Linux communication between window)

MS08067 exp 源代码 可用于研究并修改shellcode实现自己想要的功能(MS08067 exp source)

使用VC++和PCB编写的TCD1304阵列CCD数据采集的源码例程(Source code routine of TCD1304 array CCD data acquisition written by VC++ and PCB)

把word文件嵌入到系统中，不用另外打开其他程序，非常实用，可以应用到其他大型程序之中(Embedding word files into the system without opening other programs is very practical and can be applied to other large programs.)

设X[ 0 : n - 1]和Y[ 0 : n – 1 ]为两个数组，每个数组中含有n个已排好序的数。找出X和Y的2n个数的中位数。  编程任务 利用分治策略试设计一个O (log n)时间的算法求出这2n个数的中位数。 数据输入 由文件input.txt提供输入数据。文件的第1行中有1个正整数n（n<=200），表示每个数组有n个数。接下来的两行分别是X，Y数组的元素。结果输出 程序运行结束时，将计算出的中位数输出到文件output.txt中(Let X [0: n- 1] and Y [0: n- 1] for the two arrays, each array containing the n number has been sorted. 2n X and Y to identify the number of digits.  programming tasks using the divide and conquer strategy try to design an O (log n) time algorithm to calculate this median number 2n. Data input by the input data provided input.txt file. The first line in the file has a positive integer n (n < = 200), that there are n numbers of each array. The next two lines are the X, Y array elements. The end result is output program runs, the calculated median output to file output.txt)

从txt 等文件中读数据 并两位两位的显示出来(Txt and other documents from the read data and two out of two display)

利用已知的一些点，利用多项式模拟出椭圆（圆形），适合于数学图像算法的初学者，只要打开*.CPP文件，加入一些点的文件就可以用。自己可以拓展为多种图形的数学模拟(to simulatorsllipe， Adampt to fresh student)

说明：  [C/C++] 穿目前所有还原的下载者 C++源码 下载者包括四个工程： CDown：生成器 userinit：真正的下载者 Dat：驱动和下载者的安装程序 pass：驱动程序 原理：驱动程序可以穿透还原卡，并且可以修改系统文件，这里是通过修改系统文件userinit.exe来实现的。userinit.exe的功能很简单，就是启动explorer.exe。这里就是通过替换uerinit.exe，伪造一个userinit.exe。这个伪造的程序可以实现uerinit.exe的原始功能，并可以实现自定义的功能，比如下载执行，发送数据。 驱动的功能就是替换指定的系统文件。 将userinit Dat pass 编译出来的文件放到cdown的res里，再生成出生成器就可以使用它生成下载者，也就是这个穿还原的程序([C/C++] wear all current restore downloader C++ source code The download includes four projects: CDown: generator Userinit: a true Downloader Dat: driver and downloader installer Pass: Driver Principle: driver can penetrate the restore card, and you can modify the system file, here is through the modification of system file userinit.exe to achieve. The function of userinit.exe is simple, that is, to start explorer.exe. This is where you forge a userinit.exe by replacing uerinit.exe. This fake program can realize the original function of uerinit.exe, and can implement custom functions, such as downloading, executing and sending data. The driver's function is to replace the specified system files. The userinit Dat pass compiled files into the Cdown res, regeneration into the generator, you can use it to generate the download, that is, the process of wearing a restore)

说明：  FFT变换，可以变换将时域信号变换为频域信号，在vc6.0环境调试(FFT transform,Can change the time domain signal transformation for frequency domain signal, debugging in vc6.0 environment )
