vb程序设计教程课后答案与实验题答案-(第三版)资料
答案习题一答案在教材上找。
习题二1.对象指现实世界中的实体。
每个对象有自己的特征(属性)、行为(方法)和发生在该对象上的活动(事件)。
类是对同一种对象的集合与抽象。
类包含所创建对象的属性数据，以及对这些数据进行操作的方法。
封装和隐藏是类的重要特性，将数据结构和对数据的操作封装在一起，类的内部实现细节对用户来说是透明的。
VB工具箱中的可视图标是VB系统设计好的标准控件类。
通过将控件类实例化，得到真正的控件对象。
在窗体上画一个控件，就将类转换为对象，创建了一个控件对象。
VB中常用的对象是控件。
此外，VB还提供了系统对象。
窗体是个特例，它既是类也是对象。
当向一个工程添加一个新窗体时，实质就由窗体类创建了一个窗体对象。
对象的三要素：属性、事件和方法。
属性：存放对象的数据(决定对象外观及功能)对象属性的设置方法：在设计阶段，利用属性窗口直接设置属性值；程序运行时，通过语句[对象名.]属性名=属性值。
若属性只能在设计阶段设置，在程序运行阶段不可改变，称为只读属性。
事件：发生在对象上的事情。
同一事件，对不同的对象，会引发不同的反应。
事件过程：应用程序处理事件的步骤。
应用程序设计的主要工作就是为对象编写事件过程的代码。
方法：面向对象的程序设计语言，为程序设计人员提供了一种特殊的过程和函数。
方法是面向对象的，调用时一定要指明对象。
2.窗体和控件具有的基本属性“(1) Name属性：名称所创建的对象名称,在程序中引用。
(2) Caption属性：标题该属性决定了对象上显示的内容。
(3) Height、Width、Top和Left属性决定对象的大小和位置。
(4) Enabled 属性：对象是否允许操作(5) Visible 属性：对象是否可见(6) Font 属性组：文本的外观FontName字体、FontSize大小FontBold粗体、FontItalic斜体FontStrikethru 删除线FontUnderline 下划线(7) ForeColor属性：前景颜色(8) BackColor属性：背景颜色(9) MousePointer属性：鼠标指针类型, 设置值范围0～15，由系统指定。
vb程序设计教程习题答案
vb程序设计教程习题答案VB程序设计教程习题答案VB程序设计是一门广泛应用于软件开发领域的编程语言，它具有易学易用的特点，被广大程序员所喜爱。
在学习VB程序设计的过程中，习题是一个非常重要的环节，通过解答习题可以帮助我们巩固所学的知识，提高编程能力。
下面我将给出一些VB程序设计教程习题的答案，希望对初学者有所帮助。
1. 编写一个VB程序，实现计算两个数的和并输出结果的功能。
答案：```Public Class Form1Private Sub Button1_Click(sender As Object, e As EventArgs) HandlesButton1.ClickDim num1 As IntegerDim num2 As IntegerDim sum As Integernum1 = Integer.Parse(TextBox1.Text)num2 = Integer.Parse(TextBox2.Text)sum = num1 + num2MessageBox.Show("两个数的和为：" & sum)End SubEnd Class```2. 编写一个VB程序，实现判断一个数是奇数还是偶数的功能。
答案：```Public Class Form1Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.ClickDim num As Integernum = Integer.Parse(TextBox1.Text)If num Mod 2 = 0 ThenMessageBox.Show("这个数是偶数")ElseMessageBox.Show("这个数是奇数")End IfEnd SubEnd Class```3. 编写一个VB程序，实现计算一个数的阶乘的功能。
