可用如下语句
Set fs = CreateObject("Scripting.FileSystemObject")
建立FSO的应用

在工程->引用中选择 Microsoft Scripting Runtime即可。

这个指南让你熟悉报表设计器和了解报表设计的基本概念（各种区域，数据源，二次表，等等）。指南将帮助你开始用FastReport创建报表，但它不能告诉你怎样使用其它基本的报表设计器。如果你不熟悉报表设计器，我们建议你参考QuickReport的帮助系统。QuickReport的指南已经包含在你的Delphi拷贝中。QuickReport的大部分基本概念也适用于FastReport，然而，FastReport能提供更多的弹性和最终用户的自定义。关于FastReport的说明 FastReport是高弹性的报表设计器，用于报表的数据可以从任何类型的数据源获取，包含字符列表，BDE数据库，ADO数据源（不使用BDE），Interbase（使用IBO），Pascal数组和记录，以及一些不常用的数据源。整个FastReport系统是用Delphi的Pascal编写的。FastReport不需要动态链接库，但需在你的项目中占用大约400kb（Delphi 5）。如果你想最终用户拥有设计能力，这将在你的.EXE中增加大约500kb。虽然这看上去比较大，但这只是其它设计的几分之一。你同样应该考虑到FastReport不仅仅只是包含最终用户更改报表设计的能力，还能够适应查询和数据库的变化。FastReport还包含自己的脚本语言，让应用程序和最终用户能够更容易地改变报表。如果你的大部分应用使用FastReport，你可以简单地配置FastReport BPL（大约1400kb）而所有你的应用程序只需要保留很少的一部分。你可以发现FastReport有一个非常吸引人的用户界面，使用最新的用户界面组件，例如可停靠的工具栏。你的最终用户将会非常愿意使用这个设计器，只需使用鼠标就可以创建大多数报表。 FastReport是名副其实的快速报表：较其它一些Delphi报表设计器而言，你可以发现没有什么可以接近于它的开发速度。报表预览窗口一直是大多数报表设计器的弱点，高品质的外观，赋于你的应用程序非常专业的用户界面。 FastReport是一个已经拥有三年历史的非常成熟的报表设计器，成长使它拥有其它Delphi报表设计器所不能相比的诸多先进特性。

这个数据库看性能不错，哪位能破解一下。Overview Absolute Database: Delphi database with SQL support.Absolute Database lets you forget the Borland Database Engine (BDE). This BDE replacement is the compact, high-speed, robust and easy-to-use database engine. With Absolute Database you will not need special installation and configuration, it compiles right into your EXE. Make your application faster and smaller with Absolute Database BDE alternative!An individual may use Absolute Database Personal in a project if he / she is the only user of this project. If your project is public or if you represent a company, you must order commercial edition of Absolute Database.Key Features: No BDE; no DLLs Single-file database SQL‘92 (DDL & DML) support Single-user and multi-user mode (file-server) Unmatched ease-of-use 100% compatibility with standard DB-aware controls Strong encryption BLOB compression Free for personal use Full source code available Royalty-free Specification Ease of Deployment No BDE, no DLLs No special installation or configuration required Database engine compiles right into EXE Single-file database format Database file could be merged with the application EXE file High Speed Advanced cache management and buffering architecture Sophisticated SQL query and filter optimizer Special optimized database engine for temporary results of SQL queries Fast B*-Tree indexes with high-speed on thousands and on millions of records Buffered transactions for batch inserts, updates and deletes In-memory tables for fast operations with data loaded into memory Optimization for read-only databases, such as databases on CD High-concurrency design for multi-threaded applications Multi-User Zero-admin file-server Automatic record and table locking Automatic detection of changes made by other users Configurable limit of concurrent connections Easy switching between single-user and multi-user mode Full transactions support with ReadCommited isolation level SQL Support SELECT with DISTINCT, INNER LEFT, RIGTH, FULL and OUTER JOIN, GROUP BY and ORDER BY clauses CREATE TABLE, DROP TABLE, ALTER TABLE statements CREATE INDEX, DROP INDEX statements INSERT, UPDATE, DELETE statements BETWEEN, IN, LIKE, IS NULL, EXISTS operators Aggregate functions COUNT,SUM,MIN,MAX,AVG Most of all SQL‘92 arithmetic, logical, date-time and string functions and operators Data types conversion by function CAST SQL scripts (multiple commands separated by ‘;‘) Parameters in queries SELECT from several databases in one query Correlated and non-correlated subqueries Compactness Small size of code added into the application by the database engine units Small database file size achieved by customizable page size, compression of table metadata and other special means Automatic free space recycling for data records, index pages, and BLOB blocks Fast BLOB data compression Short indexes for string fields Low memory consumption Compatibility Support of most of TTable field data types, including BLOB fields Full compatibility with standard DB-aware visual controls such as QuickReport, DBGrid, DBNavigator, DBImage, DBMemo, DBRichEdit and others Calculated and lookup fields Most of TTable functions including Key and Range methods Support for the IProvider interface (TClientDataSet) Functionality Unicode support in String and Memo fields Multiple-fields indexes with descending, ascending, case-sensitive and insensitive options Shareable tables Default values support Min, max and not null constraints on field values Export to SQL script (reverse engineering) Security Strong encryption of database file Variety of supported encryption algorithms: Rijndael, the Advanced Encryption Standard (AES) winner 128 bit key, Rijndael 256 bit key, Blowfish 448 bit key, Twofish 128 bit key, Twofish 256 bit key, Square, Single DES and Triple DES Reliability Repair database in case of hardware failure or operating system error caused by another application Auto-detect of database corruption and automatic repair of database file Convenience Table restructuring being performed in the easiest way keeping all the existing data Data importing from and exporting to any dataset Internationalization / localization support by use of current system locale Displaying progress during potentially slow operations with the tables and databases Utilities DBImportExport utility to transfer your existing tables from database systems with BDE driver, such as Paradox, Interbase, Access, Oracle, SQL Server to Absolute Database format and vice versa.
