说明：  Blowfish对称加密算法源码，应用Blowfish对称密钥加密的一个类(Blowfish symmetric encryption algorithm source code, a class that uses Blowfish symmetric key encryption)

封装了所有网络通信接口得类，可以为了节省很多重复写代码得工作。-Packaging of all network communication interface in the category, in order to save a lot of duplication in the work of writing code.

说明：  本书繁体字版由第三波资讯股份有限公司出版。本书简体字中文版由第三波资讯股份有限公司授权清华大学出版社出版 附注项: 本书通过程序流程图来剖析程序，帮助读者彻底了解Applet的设计方法，并结合程序源代码展示、解释，轻松掌握Applet程序在网络上的运用。(Traditional version of the book published by the third wave of IT Corporation. Simplified Chinese version of the book The Third Wave Information Corporation authorized by the Tsinghua University Press Note entry: book through the program flow chart to analyze programs that help the reader a thorough understanding of Applet design method, and source code display, interpretation, easily Applet program to master the use of the network.)

加速梯度下降算法求函数最优值,用加速梯度下降算法，可以明显缩短优化时间(accelerated gradient descent algorithm)

此程序为外部升级程序(需要主程序的调用),具体代码这里就不罗列了,还是自己看源代码吧.此程序主要的思路是通过读取服务器文件获得升级版本及升级地址,有新版本则下载 如果想做成内部升级程序(在主程序内部自动检测及自动升级),只需要在主程序启动时相关的代码即可,大家不仿试试,主要的思路与这个是差不多的,不同之处是怎么处理主程序的自动关闭与启动问题.-This program is an external upgrade (requires the main program call), the specific code is not listed here, or to look up the source code for it. The main idea of this procedure is obtained by reading the file server upgrade and update address, a new version If you want to get inside is to download the upgrade process (in the main program within the auto-detection and auto-upgrade), just start in the main program code can be related, we do not try to imitate, the main idea and this is about the same, different The Department is how to deal with the main program automatically shut down and startup problems.

输入十进制数转换成二进制数输出，核心算法只有三行(Input decimal number to binary number output,The core algorithm has only three lines)

Setup function for gatable oscillator.

Must come last. If you add entries adjust this table and generic_chipsets[] appropriately.

说明：  VC6对sqlserver数据库的添加删除查询等相关操作，代码全部在VC编译环境下运行通过。(VC6 adds and deletes queries to SQLSERVER database and other related operations. All the code runs through the VC compiler environment.)
