Delphi User’s Guide

Delphi for Windows

Introduction

Agreement

Delphi represents a brand new way to develop applications for Windows. It combines

the speed and ease of use of a visual development environment with the power,

flexibility, and reusability of a fully object-oriented language, the world’s fastest

compiler, and leading-edge database technology.

As a result, Delphi lets you build sophisticated client/server applications in record time.

Delphi includes support for creating stand-alone executable (.EXE) and dynamic-link

library (.DLL) files and local or networked database applications, as well as client/

server applications.

Installing Delphi

Delphi and its installation program are both Windows applications, so you must

already have Windows running to install Delphi. The installation program creates

directories as needed and copies files from the distribution disk to your hard drive.

The installation program is largely self-explanatory. The following steps tell you all you

need to know to install Delphi.

To install Delphi,

1 Start Windows if it is not already running on your computer.

2 Insert the Delphi CD into your CD-ROM drive.

3 Use Program Manager’s File|Run menu command or File Manager to run

\INSTALL\SETUP.EXE from the Delphi CD.

4 Follow the instructions presented by the installation program.

When the installation program finishes its work, it offers you the option of reading the

README.TXT file, which contains important last-minute information about Delphi. It’s

a good idea to read README.TXT before running Delphi for the first time.

Documentation overview

Delphi includes complete documentation to help you learn to use the product quickly

and effectively.

The Delphi documentation consists of three parts:

• Printed manuals

• Online Help

• Interactive Tutors

Using this manual

• Part I, “Getting started with Delphi,” introduces you to the kinds of tasks you’ll

perform when designing and testing applications in Delphi.

• Part II, “Fundamental skills,” presents concepts and techniques you’ll use in

developing robust and sophisticated Delphi applications. These skills are discussed

in the context of creating simple but functional examples.

• Part III, “Programming topics,” discusses the language you’ll use to write your

applications, how to work with objects, and how to write robust applications by

handling exceptions.

• Part IV, “Sample applications,” presents several complete sample applications,

demonstrating most of the tasks you’ll perform when writing your own applications.

Reference material on Delphi and its component library appear in online Help.

The Delphi Component Writer’s Guide and Database Application Developer’s Guide are also

printed separately. They contain information on how to create your own components

for use in Delphi, and how to create database applications, respectively.

Using Help

Delphi’s online Help provides a superset of the information presented in the printed

manuals. Use online Help to find

• Specific procedural information regarding programming tasks in Delphi

• The language definition of Object Pascal

• Reference material for the Visual Component Library and the Run-Time Library

Using Interactive Tutors

Delphi provides seven Interactive Tutors to help you get up and running quickly:

• A “quick tour” overview of the Delphi programming environment

• A short lesson on how to create a simple application

• A lesson on how to add components to a form

• A lesson on setting component properties

• A lesson on creating and modifying event handlers

• A lesson on creating a simple database application

• A lesson on creating a more sophisticated database application

Manual conventions

The printed manuals for Delphi use the typefaces and symbols described in Table

Intro.1 to indicate special text.

Table Intro.1 Typefaces and symbols in these manuals

Typeface or symbol Meaning

Monospace type Monospaced text represents text as it appears onscreen or in

Object Pascal code. It also represents anything you must type.

[ ] Square brackets in text or syntax listings enclose optional items.

Text of this sort should not be typed verbatim.

Boldface Boldfaced words in text or code listings represent Object Pascal

reserved words or compiler options.

Italics Italicized words in text represent Object Pascal identifiers, such

as variable or type names. Italics are also used to emphasize

certain words, such as new terms.

Keycaps This typeface indicates a key on your keyboard. For example,

“Press Esc to exit a menu.”

This symbol indicates the beginning of a procedure. The text

that follows describes a set of general steps for performing a

specified kind of task.

This symbol indicates a specific action you should take, such as

a step in an example.
