主要包括：建立大学数据库的源文件，已经建立好的ACCESS数据库文件，ACCESS2007教程课件，窗体使用的经验交流课件，实验报告。希望能对学习数据库的同学产生帮助-Mainly include: the establishment of the University of the database source file, well-established ACCESS database file, ACCESS2007 tutorial courseware, the form used in the exchange of experience courseware, lab report. Hopes of learning a database created to help students

数据结构课程设计,表达式,用C语言实现,难度系数较高-data structure curriculum design, expression, using C language, the higher the coefficient of difficulty

二叉树的遍历方式，包括先序遍历 层序遍历，最后用凹入表示法表示出来，对初学数据结构的孩子很有帮助，使用文本文档写的，复制粘贴就可以用。

一个数据结构的演示程序,包含顺序表,广义表,顺序查找等-A data structure of the demo program, including the order form, the generalized form, the order of search, etc.

实现了临时建立分区和永久建立分区的效果 可以压缩和解压缩的解压缩文件-achieve the establishment of the provisional district and the establishment of a permanent regional results can be compression of the extracted files

将Canon相机拍照后自动存放到本地机器的照片，按照学工号重新命名后，保存到DB2数据库中，-Canon cameras will take pictures automatically deposited to the local machine photographs, according Xuegong, re-named after the preservation of the DB2 database,

八 方块移动游戏要求从一个含8个数字（用1-8表示）的方块以及一个空格方块（用0表示）的3x3矩阵的起始状态开始，不断移动该空格方块以使其和相邻的方 块互换，直至达到所定义的目标状态。空格方块在中间位置时有上、下、左、右4个方向可移动，在四个角落上有2个方向可移动，在其他位置上有3个方向可移 动。例如，假设一个3x3矩阵的初始状态为： 8 0 3 2 1 4 7 6 5 目标状态为： 1 2 3 8 0 4 7 6 5-Eight-box requirements of mobile games from one containing eight numbers (1-8 with express) the box, as well as a space box (with 0) of the 3x3 matrix of the initial start, and constantly move the box to make space its adjacent box and swap until they reach their defined target state. Spaces in the middle position box has the upper and lower, left and right direction of four removable, in the four corners there are two directions can be mobile, in other locations has three movable direction. For example, suppose a 3x3 matrix of the initial state as follows: 803,214,765 target state as follows: 123,804,765
