delphi编程基础

Beginner developers eager to master the Delphi programming language should already be familiar with the basics of Microsoft Windows. Learning Delphi is easiest if you approach it from a guided, tutorial-based frame of reference.

渴望掌握Delphi编程语言的初学者开发人员应该已经熟悉Microsoft Windows的基础知识。 如果您是从基于教程的指导性参考框架中学习Delphi的，那将是最容易的。

## 基础概念 **(** Foundational Concepts **)** ##

Get started with a history lesson covering the evolution of [(Turbo) Pascal to Delphi 2005][Turbo_ Pascal to Delphi 2005], such that Delphi evolved into a rapid-application-deployment framework intended to offer high-performance, scalable applications for online and mobile delivery.

从涵盖[(Turbo)Pascal到Delphi 2005][Turbo_ Pascal to Delphi 2005]演变的历史课程开始，使得Delphi演变成一个快速应用程序部署框架，旨在为在线和移动交付提供高性能，可扩展的应用程序。

After that, explore the meat-and-potatoes of what [Delphi actually is][] and how to install and configure its development environment. From there, explore the main parts and tools of the [Delphi IDE][].

然后，探究[Delphi][Delphi actually is]到底[是][Delphi actually is]什么，以及如何安装和配置其开发环境。 从那里，探索[Delphi IDE][]的主要部分和工具。

## “你好，世界！” **(** "Hello, World!" **)** ##

Begin your overview of application development with Delphi by creating a simple project, [writing code][], compiling, and running a project. Then [learn about properties, events, and Delphi Pascal][learn about_properties_ events_ and Delphi Pascal] by creating your second simple Delphi application — allowing you to learn how to place components on a form, set their properties, and write event-handler procedures to make components cooperate.

通过创建一个简单的项目， [编写代码][writing code] ，编译和运行一个项目，开始使用Delphi进行应用程序开发的概述。 然后[，][learn about_properties_ events_ and Delphi Pascal]通过创建第二个简单的Delphi应用程序来了解[属性，事件和Delphi Pascal][learn about_properties_ events_ and Delphi Pascal] ，使您能够学习如何将组件放置在表单上，设置其属性以及编写事件处理程序以使组件协作。

## 德尔福·帕斯卡(Delphi Pascal) **(** Delphi Pascal **)** ##

Before you start developing more sophisticated applications by using the RAD features of Delphi, you should learn the basics of the [Delphi Pascal][] language. At this point, you'll need to start thinking carefully about code maintenance, including code commenting, and how to [cleaning your Delphi code errors][] — a discussion on Delphi design, run and compile time errors and how to prevent them. Also, take a look at some solutions to most common logic errors.

在开始使用Delphi的RAD功能开发更复杂的应用程序之前，您应该学习[Delphi Pascal][]语言的基础知识。 此时，您需要开始仔细考虑代码维护，包括代码注释以及如何[清除Delphi代码错误][cleaning your Delphi code errors] \-有关Delphi设计，运行和编译时间错误以及如何防止它们的讨论。 另外，看看一些最常见的逻辑错误的解决方案。

## 表格和数据库 **(** Forms and Databases **)** ##

In just about every Delphi application, we use forms to present and retrieve information from users. Delphi arms us with a rich array of visual tools for creating forms and determining their properties and behavior. We can set them up at [design time][] using the property editors and we can write code to re-set them dynamically at runtime. [Look][] at simple SDI forms and consider some good reasons for not letting your program auto-create forms.

在几乎每个Delphi应用程序中，我们都使用表单来呈现和检索用户的信息。 Delphi为我们提供了丰富的可视化工具，用于创建表单并确定其属性和行为。 我们可以在[设计时][design time]使用属性编辑器对其进行设置，并且可以编写代码以在运行时动态地对其进行重新设置。 [查看][Look]简单的SDI表单，并考虑一些不允许您的程序自动创建表单的充分理由。

[Delphi Personal][Delphi IDE] edition does not offer database support, but you can [create your own][] *flat* database to store any kind of data — all without a single data-aware component.

[Delphi Personal][Delphi IDE] Edition不提供数据库支持，但是您可以[创建自己的][create your own] *平面*数据库来存储任何类型的数据-所有这些都无需单个数据感知组件。

## 管理工作 **(** Managing Your Work **)** ##

While you're developing a large Delphi application, as your program becomes more complex, its [source code][] can become hard to maintain. Create your own code modules — Delphi code files that contain logically associated functions and procedures. Along the way you should explore Delphi's built-in routines and how to make all the units of a Delphi application cooperate.

在开发大型Delphi应用程序时，随着程序变得越来越复杂，其[源代码][source code]可能变得难以维护。 创建自己的代码模块-包含逻辑上相关的函数和过程的Delphi代码文件。 在此过程中，您应该探索Delphi的内置例程，以及如何使Delphi应用程序的所有单元相互配合。

The Delphi IDE (the [code editor][]) helps you effectively jump from a method implementation and a method declaration, locate a [variable declaration][] using tooltip symbol insight features, and more.

Delphi IDE( [代码编辑器][code editor] )可帮助您有效地从方法实现和方法声明中跳转，使用工具提示符号洞察功能定位[变量声明][variable declaration]等。
