简单的碰撞检测程序源代码及演示,包含vc 2005 工程项目．不错的(Simple collision detection program source code and demo, including vc 2005 project. Good)

说明：  香农第一定理指出了平均码长与信源之间的关系，同时也指出了可以通过编码使平均码长达到极限值，这是一个很重要的极限定理。(Shannon first theorem that the average yards long with the letter of the relationship between the source, it has also pointed out the code can make the average yards long reach limits, this is a very important Limit Theorem.)

（１）、Ｉ：初始化（Initialization）。从终端读入字符集大小n,以及n个字符和n个权值，建立哈夫曼树，并将它存于文件hfmTree中。 （２）、Ｅ：编码（Encoding）。利用以建好的哈夫曼树（如不在内存，则从文件hfmTree中读入），对文件ToBeTran中的正文进行编码，然后将结果存入文件CodeFile中。 （３）、Ｄ：译码（Decoding）。利用已建好的哈夫曼树将文件CodeFile中的代码进行译码，结果存入文件TextFile中。 （４）、Ｐ：印代码文件（Print）。将文件CodeFile以紧凑格式显示在终端上，每行50个代码。同时将此字符形式的编码文件写入文件CodePrin中。 （５）、Ｔ：印哈夫曼树（Tree printing）。将已在内存中的哈夫曼树以直观的方式（树或凹入表形式）显示在终端上，同时将此字符形式的哈夫曼树写入文件TreePrint中((1), I: initialization (Initialization). From the terminal to read the character set size n, as well as n characters and N weights, build Huffman tree and save it in file hfmTree. (2), E: Code (Encoding). Using the built Huffman tree (if not in memory, read from the file hfmTree), the text in the file ToBeTran is encoded, and the result is stored in the file CodeFile. (3), D: decoding (Decoding). Using the built Huffman tree to decode the code in file CodeFile, the result is stored in file TextFile. (4), P: printed code file (Print). The file CodeFile is displayed in a compact format on the terminal, with 50 codes per line. At the same time, the encoding file of this character form is written to file CodePrin. (5), T: Tree printing. The Hoffman tree, already in memory, is displayed on the terminal in an intuitive way (tree or concave form), and the Hoffman tree of this character is written into the file TreePrint.)

该源码的前台用C++编写，后台用SQL数据库支持，可以实现酒店的日常业务管理。(The source of the future with C++ Prepared background with SQL database support, you can realize the hotel)

本实例为VS2005编写的ARX事务管理实例，特别是AcTransaction::getObject()和close()的使用方法，作了正确演示。(ARX transaction management example this example is written in VS2005, especially in AcTransaction:: getObject () and close () method of use, make the correct demonstration.)

这是一个模拟服务器发送远程通知的类

openssl在qt的使用，包含证书认证。包含server、client两部分，已经在Ubuntu Linux虚拟机里构建并运行测试过，证书认证通过。 如果使用openssl在qt上成功进行了证书认证和签名的请消息我、我在使用QSslSocket开发时遇到困惑、需要交流。
