习题参考答案第1章Visual Basic编程环境与简单程序设计一、选择题二、填空三、问答题1.主要有以下特点：(1)具有面向对象的可视化设计工具。
Visual Basic 6.0提供可视化平台,把Windows界面设计的复杂性封装起来,编程人员不必为界而的设计编写大量的代码。
界面的设计代码是山Visual Basic 6.0自动产生的, 大大提高了编程效率。
(2)事件驱动的编程机制。
在事件驱动的应用程序中，代码是在响应不同的事件时执行不同的代码片段。
事件可以山用户操作或应用程序本身的消息及操作系统或其他应用程序的消息触发。
(3)结构化的程序设计语言。
(4)开放的数据库功能与网络支持。
(5)充分利用Windows资源。
2.主要窗口有：(1)窗体窗口。
(2)工程资源管理器。
(3)属性窗口。
(4)窗体布局窗口。
(5)代码窗口。
它们均可通过Visual Basic 6. 0集成环境中“视图”菜单的相关选项打开；关闭时单. 击各个窗口右上角的“X”即可。
3.工程资源管理器显示当前所打开的工程的信息状态和文件内容。
利用工程资源管理器可以进行与工程相关的管理操作，比如添加、删除文件等。
在工程资源管理器中所能进行的工程管理操作主要有：(1)查看对象：单击该对象，单击工具栏上的“查看对象”按钮，包含该对象的窗体窗口将出现在屏幕上。
(2)查看代码：单击该对象，单击工具栏上的“查看代码”按钮，与该对象相关的代码窗口将被打开。
(3)添加对象：用鼠标指针指向工程名称，单击右键，系统会弹出一个快捷菜单。
在该菜单上选择“添加”选项，稍候出现二级菜单，选择所要添加的对象类型即可。
(4)删除对象：选择要删除的对象，在要删除的对象项上单击右键，在弹出的快捷菜单中选择“删除”即可。
(5)保存对象：当某些文件修改后，要及时保存这些文件。
选择要保存的对象，在要保存的对象项上单击右键，在弹出的快捷菜单中选择“保存”或“另存为”叩可。
4 .工程所可以包含的文件类型为：(1)工程文件(.vbp)：跟踪所有对象。
(2)窗体文件(.fun)：存储有关窗体的信息。
(3)二进制数据文件(.frx)：每个窗体都有一个相应的二进制数据文件，它包含窗体上控件的属性数据。
对含有二进制属性的任何.frx文件都是不可编辑的，这些文件都是由系统自动产生的。
(4)模块文件(.bas)：每个标准模块的一个文件，该文件是可选项。
(5)类模块文件(.cis)：每个类模块的一-个文件，该文件是可选项。
(6)Active X控件文件(.ocx)：包含Active X控件的文件，该文件是可选项。
(7)资源文件(.res)：包含无须重新编辑代码便可以改变的位图、字符冷和其他数据, 该文件是可选项。
