程序信息文件

Friends addendum to the information obtained the document procedures, hope to offer help.

朋友编的取得文件信息的程序，希望能提供帮助。

In the CAD system for progressive dies, the method is introduced to automatically generate geometric models of stampings through inputting the product drawings by AutoCAD and picking-up the entity information from DXF files and programming with ObjectARX and C＋＋ language, at the same time, generating algorithm of close contour lines and unidirectional chain-table structure are used to express the models of stampings, the class and direct judgment of contour lines are realized and the entity existing side is judged by analytical geometry, which efficiently solves the problem of automatic input of drawings of stamping and providing information of process planning and mold design.

在级进模CAD系统中，将产品的图形信息以AutoCAD直接绘图形式输入到计算机中，从AutoCAD的图形交换文件中提取信息，采用面向对象的二次开发工具ObjectARX和C＋＋语言编写接口程序，并通过封闭轮廓的生成算法自动生成冲裁零件的几何模型，且用单向链表的形式加以表达，同时对冲裁零件图形的轮廓进行分类与走向判定，采用简单的解析几何方法对实体存在侧进行判定，有效地实现了零件图形的自动输入，为级进模CAD系统的工艺计算和模具工作部分的设计等提供了必要的信息。

The extraction program assigns a layout identifier to each data record retrieved from the database based on the type of information contained within the data record a nd how the information is to be formatted in the document.

抽取程序根据包含在数据记录中的信息类型及如何在文件中格式化信息将布局标识符分配给从数据库中检索出的各数据记录。

The META-INF directory, if it exists, is used to store package and extension configuration data, including security, versioning, extension and services.

很多情况下，JAR文件不但可以打包java类和程序资源，还可以用于构建应用程序的组件，如果存在META-INF目录，它可以用来存储扩展的配置信息，比如安全、版本、服务等。

An American team explored a temple, which stands in an ancient city on the promontory of Ayia Irini.

文件是指记录在存储介质上的一组相关信息的集合，它可以是程序、数据或其它信息。

The program reads the packet MEPG2 binary file, and the package of Teletext information check out, re-write back to a new binary file.

该程序读取了MEPG2的包的二进制文件，并且把该包中的Teletext的信息取出来，重新写回一个新的二进制文件。

Int nul, oldstdout;char msg ="This is a test";nul = open("123.txt", O_CREAT | O_RDWR | S _IREAD | S_IWRITE);oldstdout = dup;dup2;close;writeSTDOUT, msg, strlen(msg;return 0

这个程序结果是MSG的信息只会写入到123.txt文件里，因为nul是一个可用的文件描述符，DUP2调用成功返回filesdes2的值，若filedes2已经打开泽先将其关闭。

Mobile phone number information in the computer information in the frequency of occurrence is very high, very broad scope, there will be, interludes in all kinds of information, documents, procedures for the middle.

手机电话号码资料信息在计算机中的出现频率是很高的，范围也很广，会出现，穿插在各种信息、文件、程序中间。

From ORACLE system structure, the paper organizes and allocates memory with SGA and PGA. The key of performance tuning is to confirm the hit ratio of system. The ORACLE system's store structure includes physicial structure and logical structure. So , it is the basis to decide the size of tablespace, data file and control file. The database object includes index, cluster, views and store procedure etc., the object have important effect on database. Lastly, it contrasts the ways of Based on Cost and Based on Rule and organizes the SQL under SQL/PLUS system environment.

本文从目前的医院信息系统现状分析，提出系统性能评价指标，并从ORACLE体系结构出发，对内存区中的系统全局区及程序全局区进行合理的组织与分配，确定合理的命中率，这是性能优化的关键；ORACLE存储结构采用的互为关系的逻辑存储结构与物理存储结构，故确定其中的表空间、数据文件、控制文件的大小是性能优化的基础；数据库对象结构中的索引、簇、视图、存储过程等对其进行合理的设计，对大型数据库的性能有着重要的影响；最后便是在SQL／PLUS境下，通过与基于代价与基于规则的方法进行比较，对合理高效的SQL语句进行组织，并列出优化后系统性能的情况。
