说明：  GPS导航系统，控制台程序，内附操作说明(GPS navigation systems, operating instructions included)

本程序通过用户输入范围而求出范围内所有的质数 (The scope of this program through the user input to derive all the prime numbers within the range)

VB使用SHEmptyRecycleBin方法， 依赖于shell32.dll动态链接库清空回收站，点击窗口中的按钮即可一键清空回收站。本源码主要是熟悉SHEmptyRecycleBin函数的使用，这个函数不只有清空回收站的功能，还可以统计查询回收站中的文件数量，占用字节大小等。 (VB using the SHEmptyRecycleBin method, relies on the dynamic link library shell32.dll empty the recycle bin, click on the window button quick clear recycling station. The main source is the use of familiar with the SHEmptyRecycleBin function, this function is not only the empty recycle bin function, can also query statistics the number of files in the recycle bin, occupy the byte size etc.. )

说明：  可求任意长整数的加减法，输入格式为1，1111，1111类型的格式(Rectifiable arbitrary long integer addition and subtraction, enter the format type of format 1,1111,1111)

VB to achieve real multi-threaded operation of the code can go

编写C程序，随机给出n*n的邻接矩阵，并打印输出邻接矩阵，以及有向图的边的个数，每个顶点的度，并判断该图中是否存在Euler回路： （1）如果为n阶，则随机产生一个n*n的邻接矩阵； （2）输出邻接矩阵，边的个数，每个顶点的度以及图中是否存在Euler回路。 这个题目涉及到了两个主要的知识点，一个是数据结构中的有向图的邻接矩阵的创建，还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)

自己编写的Access数据库 库存查询系统 编译器vs2005.MFC类库。 查询功能分解详细，大部分索引使用下拉菜单设计，自动搜索数据库添加相应内容，方便查询，免去按键手动添加...,数据添加方便，适用于Excel整体导入，方便维护。 库存查询-按enter自动查询所有库存及按索引查询 出库跟踪-按enter自动查询所有借用信息及按索引查询 借还操作-借用及归还操作 数据库维护-添加删除修改及excel数据整体导入 借用权限设定-借用人员信息添加(Access database inventory query compiler vs2005.MFC write your own class library. Query function decomposition in detail, most of the index using the drop-down menu design, automatically search the database to add the appropriate content, easy access, remove the keys manually add ... data add convenience for Excel overall import, convenient maintenance. Stock Search- enter automatically query inventory and check out the library index tracking- enter automatically query all borrowed index query lending operation- borrowed and returned to the operating database maintenance- add overall import borrow delete modify and excel data permissions given- to borrow personnel information to add)

利用上题的线性表，编程下列功能：假设以两个元素依值递增有序排列的线性表A和B 分别表示两个集合，现要求另辟空间构成一个线性表C，其元素为A和B元素的交集，且表C中的元素也是依值递增有序排列。(The use of the title of the linear form, programming the following features: Assuming two elements by incrementing the value ordered linear tables A and B represent two sets, are now required to open up space to form a linear table C, whose elements A and intersection B elements, and the elements in the table C is incremented by an orderly arrangement.)

自宣言型记时器，可以自定义记时方式，标题，时间长度等。(Since the Declaration type chronograph, you can customize chronograph, title, time, length and so on.)

说明：  Description Michael喜欢滑雪百这并不奇怪， 因为滑雪的确很刺激。可是为了获得速度，滑的区域必须向下倾斜，而且当你滑到坡底，你不得不再次走上坡或者等待升降机来载你。Michael想知道载一个区域中最长底滑坡。区域由一个二维数组给出。数组的每个数字代表点的高度。elements in that rectangle. In this problem the sub-rectangle with the largest sum is referred to as the maximal sub-rectangle. ()
