各个数据库的分页算法,看起来还是很有用的,所以拿出来分享给大家!-Paging algorithm for each database, it seems it is useful, so come to share for everyone!

本人原创（delphi程序设计提高与应用）源码。本实例利用ADO组件与Access数据库连接，并可将其中的数据表中的数据生成word报表及Excel文件。源码中几乎所有的步骤都有详尽的说明，是delphi初级数据库编程人员快速进入状态的实用案例。-My original (delphi improve program design and application) source. The examples of the use of ADO components with the Access database connection, the data could be data in the table below to generate word statements and Excel documents. Source of almost all the steps are very detailed, is the primary database delphi programmers to quickly enter the state of practical cases.

操作系统中的文件是通过文件目录项来管理的，为了管理和查找的方便，按层次把文件目录项组织起来，同一层上的目录构成该层上的目录，第一层为根目录，一下为各层子目录。 假设以一串字符代表一个文件，每个字符表示一个记录。 在建立上述目录结构的基础上，建立相应的管理系统并要求完成以下各项操作： 1． 一次建立各个文件 2． 查访两个用户的所有文件 3． 查访用户sun 是否有文件AB 4． 删除用户sun的文件AC,然后在分别查访两个用户的全部文件，检查是否已经删除文件AC 5． 撤销用户sun,并检查是否被删除 6． 删除用户sun的全部文件，然后在撤销sun用户，在查访用户sun, 检查其是否已被撤销。 在建立一个新用户及新用户的两个文件，然后查该两个用户的所有文件-operating system, the paper is to document catalog items to the management, in order to manage and facilitate the search, according to the document level directory entries organizations, the same floor on which constitute the directory contents on the floor, the first layer of the root directory to look for levels of subdirectories. Assuming that the representative of a string of characters, each character expressed a record. In establishing the directory structure on the basis of the establishment of a corresponding system of management and asked to accomplish the following : 1. Once established two separate files. Visits to the two users of all three docum

1、 用随机数生成的方式（要求用户输入随机数）产生一个迷宫：“1”表示墙，“0”表示路，最后的路径用“8”表示，若没有路径则打印报文，若有路径则打印出路径。 2、 通过堆栈及判断实现迷宫的自动寻找路径功能 -1, the random number generator of (requiring user input random number) produces a maze : "a" Wall said, "0" Lu said, the final path with "8" that if no path was reportedly Print text, if it were printed out trails path. 2, stack and judgment to achieve the labyrinth path function to automatically search
