Chapter One introduction of-delphi (i) (2)

Some of the early programming languages with OOP performance, such as C++,pascal,smalltalk, although with object-oriented features, but not easy to draw visual objects, and user interaction is poor, programmers still have to write a lot of code. The introduction of Delphi fills in this blank. You don't have to set up your own objects, just add the complete code to the program framework provided, and the rest is given to Delphi. To generate a beautiful interface and good structure of the program does not have to rack your brains, Delphi will help you to complete easily. It allows the Object Pascal language to be used in a visual programming environment with real OOP extensions. This revolutionary combination makes visual programming closely integrated with object-oriented development frameworks.

1.2 Delphi Quick Start

In this section, we develop a small program. With the development of the process, step-by-Step introduction of Delphi's main components and their operating methods. It is recommended that the reader follow the process described in this book and operate directly on your computer. You will be the visual programming of Delphi intuitive, fast understanding, will play a multiplier effect.

1.2.1 Access to Delphi visual programming environment

1.2.1.1 installation Delphi

The installation of Delphi is no different from other application software. Version 2.0 must be used in an operating system above Windows 95. After you start Windows 95 or Windows NT, put the Delphi CD in the CD drive (CD-ROM) and run the \install\setup on the CD. EXE file, its installer will prompt you to properly load Delphi. If you are installing Delphi in the Microsoft Chinese Windows environment, please refer to Appendix A to set up your BDE environment to facilitate the processing of Chinese data.

1.2.1.2 into the Delphi environment

To avoid hiding behind the Delphi Program manager and other programs that have been running to disrupt the layout and distract you, you might as well turn off other apps before you start Delphi, and then minimize the hidden in the back of the Delphi 2.0 program group. So the screen will only leave the Delphi window visible.

The first time you load Delphi, there are four windows on the screen:

The Delphi main window titled "Delphi-project1"

Object Inspector Window

Form window with title "Form1"

The Code editing window titled "Unit1.pas". Most of this window was masked by the "Form1" form when it was first started. Move the Form1 form away, or click the status line below the Form1 form to make it all visible. You can restore the main form visible by clicking the mouse at any visible location in the Form1 form
