【PB9.0实例项目代码】是一个集合了多个基于PowerBuilder 9.0开发的实践项目的资源包。这个包包含了两个主要的系统：学生选课系统和图书借阅系统，旨在帮助用户理解和学习如何在PB9.0环境中设计和实现实际的应用程序。以下是关于这些知识点的详细解释： 1. **PowerBuilder 9.0**: PowerBuilder 9.0是由Sybase公司（现为SAP的一部分）开发的一种可视化、面向对象的编程环境，主要用于构建数据库应用程序。它以其数据窗口组件而闻名，能够方便地与各种数据库进行交互。 2. **学生选课系统**：这是一个常见的企业级应用，用于管理学生的选课流程。它可能包括功能如学生信息管理、课程信息展示、选课操作、课程表生成等。开发者可能使用PB9.0的窗口、菜单、数据窗口等组件来实现这些功能。 3. **图书借阅系统**：这类系统通常用于图书馆自动化管理，包含图书信息管理、读者信息管理、借阅与归还操作、逾期提醒等功能。在PB9.0中，开发者会利用数据窗口处理数据库交互，创建用户友好的界面以进行图书操作。 4. **创建窗体**（第06章）：在PB9.0中，窗体是应用程序的基础，用于展示用户界面。用户可以使用拖放工具从对象库中添加控件，如按钮、文本框、列表等，以构建复杂的用户交互界面。 5. **数据库文件**：PB9.0支持多种数据库，如SQL Server、Oracle、MySQL等。数据库文件存储了应用程序的数据，通过数据窗口组件可以方便地读取、修改和保存数据。 6. **创建菜单和工具栏**（第07章）：菜单和工具栏是用户与应用程序交互的重要元素，PB9.0提供了强大的设计工具来创建自定义的菜单和工具栏，使用户能快速访问常用功能。 7. **典型小型实例赏析**（第11章）：这部分可能包含了其他简单的PB9.0程序示例，用于展示如何解决特定问题或实现特定功能，帮助初学者快速上手。 8. **应用程序的调试和发布**（第10章）：调试是检查并修复代码错误的过程，PB9.0提供了强大的调试工具。发布则是将完成的应用程序打包，使其能在目标环境中运行。这部分内容将介绍如何在PB9.0中进行这些操作。 通过学习这些实例项目，开发者不仅可以掌握PB9.0的基本语法和特性，还能了解到如何设计和实现一个完整的业务系统，从而提升实际开发能力。同时，附带的“源代码的使用方法.doc”和“下载说明.htm”文档将提供额外的指导，帮助用户更好地理解和使用提供的代码。
