基于jxta的P2P框架的系统，主要功能有局域网聊天、文件共享系统、白板等-base on jxta

说明：  文本语音转换VC源代码，作用就是把通过TTS引擎把文本转化为语音输出。(The text-to-speech conversion VC source code is used to convert text to voice output through the TTS engine.)

send email ,实现了简单的邮件发送功能 -send email to achieve a simple function of mail sent

北京邮电大学微机原理硬件实验，关于音乐盒的实现(Beijing University of Posts and Telecommunications Microcomputer Principle hardware experiments, on the realization of the music box)

BEMD对图像进行分解，包络构造使用Delaunay三角剖分与三次插值，的的到分解的结果。输入：灰度bmp图像输出：imf1 imf2 imf3 残差 (BEMD decomposition of the image, envelope constructed using the Delaunay triangulation with cubic interpolation of the result of decomposition. Input: grayscale bmp image output: imf1 imf2 imf3 residuals)

用BCB6.04编写的舍6入5看齐，奇进偶不进的数值修约法 根据GB8170—87《数值修约规则》［2］及GB3101—93附录B《数值修约规则》［3］，修约时不能简单地采用“4舍5入”的办法。应遵循的原则是：①拟舍弃的数字的最左一位数字等于、小于4，则舍去；大于、等于6，则进1。②拟舍弃数字的最左一位数字等于5，若其右边数字并非全部为“0”时，则进1；其右边数字皆为“0”时，所拟保留的末位数字若为奇数则进1，若为偶数或“0”则不进。(BCB6.04 prepared with care in line 6 to 5, Ki Jin Jin does not even repair some of the numerical method in accordance with GB8170-87 Numerical revision of the rules [2] and GB3101-93 Appendix B Numerical revision of the rules [3], when revision can not simply use 4 homes 5 in approach. Should follow the principle is: ① to give up most of the figures, a figure equivalent to the left, less than 4, then rounding greater than, equal to 6, then enter 1. ② figures to be the most left-up a digital equivalent to 5, if not all of the right figure for the 0 , then enter 1 its right figures are 0 when the bottom of the figures to be retained if it is an odd number into 1, if an even number or 0 does not enter.)

VC++ 使用MFC ODBC访问数据库，请注意：在VC环境下运行程序前，必须注册ODBC数据源，数据库文件为bookinfo.mdb，数据源名称为bookinfo，直接运行可执行文件也需要将数据库文件与可执行文件放在同一路径下(VC++ using MFC ODBC to access the database, please note: In the VC environment before running the program, you must register ODBC data source, the database file is bookinfo.mdb, data source name is bookinfo, also need to run an executable file with an executable database files files in the same path)

在对话框中利用CFile类实现对另外一个对话框中输入文件的所有内容(In the dialog box using CFile class implements a dialog box on the other all the content in the input file)

vitetbi 约束长度为7，可以直接运行(vitetbi constraint length 7 can be run directly)

扫描计算机端口是否打开，这是系统编成和计算机防护的重要-scan on whether to open up a computer port, which is the computer systems organization and the importance of protection behind
