题目内容：在以二叉树表示算术表达式的基础上,设计一个十进制的四则运算的计算器()

c#和vb的dll相互调用，包含源码，提供参考(C# and VB DLL call each other)

说明：  一种基于DirectShow 框架的实时视频彩色图像增强方法(A real-time video based on DirectShow framework for color image enhancement method)

上传程序用于解析Novatel输出range 信息，解析结果已经验证。(The upload process is used to resolve the Novatel output range information, analytical results have been verified.)

说明：  上位机主要负责以界面 的形式与用户交互，将下位机提供的各种操作以 UI 界面的形式呈现在用户端，支持解析显示 存储多种气体传感器数据，同时通过下位机系统进行水体环境改变及维持。可支持各图 形操作；对整机组装进行了手动操作环境下的调试，对取得的数据进行了操作与结果分析(The upper computer is mainly responsible for interacting with users in the form of interface, presenting various operations provided by the lower computer in the form of UI interface, supporting analytical display and storage of various gas sensor data, and changing and maintaining the water environment through the lower computer system. The results of manual operation are analyzed)

VB打印条形码的测试程序，不包括其它的功能，只是演示如何将条码打印出来，功能单一，不过容易理解，VB6.0打印条形码无思路的可参考。 (VB test program print bar codes do not include other functions, but demonstrates how to print out barcodes, single function, but it is easy to understand, VB6.0 print barcodes without thinking can be found.)

说明：  VB。NET写的数据库管理系统，数据库为ACCESS，OLEDB驱动(VB.NET was database management systems, database for ACCESS, OLEDB driver)

基于NIOS II的LED屏贪食蛇设计，基于NiosII软核处理器和LED点阵显示屏的贪吃蛇游戏内容是：一条蛇在封闭的围墙里，围墙里随机出现一个食物。玩家通过4个按键控制蛇上下左右移动，且蛇只能沿着头运动的轨迹移动。蛇头撞到食物，则食物被吃掉，蛇身体增长一节，同时记1分，又出现食物，等待蛇通过玩家的控制来吃掉，如果蛇头在移动中出界或咬到自己的身体则游戏结束，并且加入了一些附加功能如蛇身加速，选择难度，开关机屏幕画面的优化等一系列功能，使游戏更具可玩性。(NIOS II LED screen Snake design, NiosII based soft-core processor and LED dot matrix display Snake game content is: a snake in a closed fence, the fence was a random food. Players control a snake through 4 keys to move around, and the head of the snake can move along the track movement. Snakeheads hit the food, the food is eaten, the snake grow body section, but remember one point, appeared foods, through the player controls a snake waiting to eat, if snakeheads bite out of bounds or move their bodies in the game end, and added some additional features such as snake acceleration, choose the difficulty to optimize switching machine screen and a series of features that make the game more playable.)

此为电表售电管理系统，采用MFC制作，里面有详细的使用VC做数据库的及时间控制的经典源码(IC_MFC)

通过GDI获图，哈夫曼压缩，另一端进行监控，无需进行库连接。(Been through the GDI diagram, Huffman compression, the other side of monitor without the need for database connectivity.)
