可以实现对数据层的操作，对数据业务逻辑进行处理(The operation of the data layer, business logic on the data processing)

说明：  在运行本程序时，检索整个局域网络，将局域网中的计算机名和IP地址显示在ListControl空间中。(Running the program, search the entire local area network LAN of the computer name and IP address appears in ListControl space.)

主要实现MFC Tabctrl控件的按Tab快捷键改变控件焦点的功能。焦点可在TabCtrl控件，子窗口，父窗口之间自由切换。(The main realization of MFC Tabctrl control, press the Tab shortcut keys change the focus of the control function. The focus can be freely switched between the TabCtrl control, child window, and parent window.)

该系统应具有以下功能： （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）。利用已建好的哈夫曼树（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：打印代码文件（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：打印哈夫曼树（Tree printing）。将已在 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。 (The system should have the following features: (1) I: initialization (Initialization). Read from the terminal character set size n, and n and n characters right value, establishes a Huffman tree, and save it in the file hfmTree in. (2) E: encoding (Encoding). Has been built using the Huffman tree (if not in memory, reads from the file hfmTree), the text of the document ToBeTran encoded, and then putting the result in the CodeFile file. (3) D: decoding (Decoding). Huffman tree has been built using the file CodeFile the code will be decoded, the result is stored in the file TextFile. (4) P: Printing code files (Print). CodeFile in a compact format the document displayed on the terminal, one per line 50 code. While this character in the form of written documents CodePrin encoded file in. (5) T: Print Huffman tree (Tree printing). Would have been in the Huffman tree in an intuitive way (tree or recessed table form) displayed on the terminal, but this form of characters written to the file )

该程序用MFC实现串口通信，包括串口通信的整个过程，和各种参数的设置(MFC realize the program with serial communication, including the serial communication of the whole process, and various parameters set)

网上收集的常用pragma指令的用法，对于使用其他c++库很值得学习(Online collection of common usage of pragma directives for the use of other c++ Library is worth learning)

一个朋友做的工具软件,为了下载一个有用的源码,不得不把他出卖了,()

扫雷程序外挂，真正的算法实现（非读内存方法），高级最快3～5秒，有具体的算法解释说明(Plug-in de-mining process, the real algorithm (non-memory methods of reading), Senior fastest 3 ~ 5 seconds, there are specific explanations of the algorithm)

说明：  程序实现了GPS+BDS双系统双频标准单点定位。(The dual system dual frequency standard single point positioning is realized.)
