VB小程序设计实例引言VB（Visual Basic）是一种广泛应用于Windows平台的编程语言，它具有简单易学的特点，因此非常适合初学者入门。

本文将以一个实际的VB小程序设计实例为例，介绍如何使用VB语言进行简单的程序开发。

项目背景我们的目标是创建一个简单的VB小程序，用于管理学生信息。

该程序将允许用户添加、删除和修改学生的基本信息，例如姓名、年龄和班级。

此外，用户还可以根据特定条件检索学生信息，并显示学生列表。

设计步骤1. 创建VB项目首先，打开Visual Studio并选择“创建新项目”，然后选择“Visual Basic”作为项目类型。

接下来，选择“Windows Forms应用程序”作为模板，并给项目命名。

点击“确定”按钮以创建新的VB项目。

2. 设计用户界面在VB中，用户界面是通过拖放控件来创建的。

在“工具箱”中选择所需的控件，例如按钮、文本框和标签，并将它们放置在窗体上。

使用控件的属性面板可以更改它们的外观和行为。

3. 编写代码现在，我们需要为各个控件添加相应的事件处理程序。

例如，当用户点击一个按钮时，我们需要执行特定的操作。

首先，选择要添加事件处理程序的控件，然后在属性面板中找到“事件”部分。

在相应的事件上双击以创建并打开处理程序。

4. 实现学生信息管理功能在代码中，我们需要定义学生类和学生信息管理类。

学生类包含学生的属性，例如姓名、年龄和班级。

学生信息管理类包含对学生信息进行增删改查的方法。

我们可以使用集合类来存储学生对象，并使用LINQ进行查询操作。

在事件处理程序中调用适当的方法以实现相应的功能。

5. 运行和测试程序在完成代码的编写之后，我们可以点击“运行”按钮来启动程序。

通过与程序交互，测试各个功能是否按预期工作。

如果发现问题，可以调试程序并对代码进行调整。

6. 部署和发布程序一旦我们满意了程序的功能和性能，我们可以将程序部署和发布给其他人使用。

在Visual Studio中，选择“生成”菜单并点击“发布”选项。

实验一：（带有进度条的倒计时程序）Public Class Form1Dim timers As IntegerDim temp As IntegerPrivate Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.TickIf (ProgressBar1.Value + ProgressBar1.Maximum / timers < ProgressBar1.Maximum) Then ProgressBar1.Value += ProgressBar1.Maximum / timersElseTimer1.Enabled = FalseProgressBar1.Value = ProgressBar1.MaximumMessageBox.Show("进度完成！")End Iftemp += 1Label1.Text = temp.ToString()End SubPrivate Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Loadtimers = 30End SubPrivate Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Clicktimers = Val(InputBox("输入", "请输入总时间。

", 30, 0, 0))End SubPrivate Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickTimer1.Enabled = TrueEnd SubEnd Class实验二（定时器控制蝴蝶飞舞）Public Class Form1Dim t As IntegerPrivate Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick’Dim t As Boolean' If t = True Then' PictureBox3.Image = PictureBox2.Image' t = False'Else' PictureBox3.Image = PictureBox1.Image' t = True'End IfSelect Case tCase 0PictureBox3.Image = PictureBox1.Imaget = 1Case 1PictureBox3.Image = PictureBox2.Imaget = 2Case 2PictureBox3.Image = PictureBox1.Imaget = 3Case 3PictureBox3.Image = PictureBox1.Imaget = 0End SelectEnd SubEnd Class实验三（递推法迭代法--猴子吃桃）Public Class Form1Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickDim n, y As Integern = Val(TextBox1.Text)y = Val(TextBox2.Text)Dim xi As Doublexi = yTextBox3.Text = "第" + n.ToString() + "天的桃子为：" + y.ToString() + "个。

VB程序代码(简单小程序) Option Explicit
Private Sub btnCalculate_Click()
'按钮点击事件，计算两个数的和
'声明变量
Dim num1 As Double
Dim num2 As Double
Dim result As Double
'获取用户输入的数字
num1 = Val(txtNum1.Text)
num2 = Val(txtNum2.Text)
'计算和
result = num1 + num2
'将计算结果展示给用户
lblResult.Caption = "计算结果：" & result
End Sub
Private Sub Form_Load()
'窗体加载事件，初始化窗体
'设置窗体标题
Me.Caption = "简单计算器"
'设置标签的默认文本
lblNum1.Caption = "请输入第一个数："
lblNum2.Caption = "请输入第二个数："
lblResult.Caption = ""
如上所示，这是一个简单的VB程序，包含一个窗体和三个按钮，分别用于计算两个
数的和、清空所有输入框和标签的内容以及退出程序。

用户可以在两个文本框中输入数字，点击计算按钮后，程序会将两个数字相加并将结果展示给用户。

如果用户想重新计算，可
以点击清空按钮清除所有输入框和标签的内容，重新输入参数。

VB小程序代码VB小程序是使用Visual Basic语言编写的小型应用程序。

它可以在Windows操作系统上运行，并提供了丰富的图形用户界面和功能。

本文将详细介绍如何编写一个简单的VB小程序代码，并提供一些示例来帮助您更好地理解。

1. 程序结构一个VB小程序通常由以下几个部分组成：a) 引用：您可以引用其他程序集或库来扩展您的程序功能。

b) 命名空间：命名空间用于组织和管理程序中的类和对象。

c) 类：类是VB程序的基本构建块，它包含了变量、属性、方法和事件等成员。

d) 窗体：窗体是用户界面的容器，您可以在窗体上添加控件来实现交互功能。

2. 示例代码下面是一个简单的VB小程序代码示例，演示了如何创建一个窗体，并在窗体上添加一个按钮和一个文本框。

```vbImports System.Windows.FormsNamespace MyProgramPublic Class MainFormInherits FormPrivate WithEvents myButton As ButtonPrivate myTextBox As TextBoxPublic Sub New()myButton = New Button()myButton.Text = "点击我"myButton.Location = New Point(50, 50)myTextBox = New TextBox()myTextBox.Location = New Point(50, 100)Controls.Add(myButton)Controls.Add(myTextBox)End SubPrivate Sub MyButton_Click(sender As Object, e As EventArgs) Handles myButton.ClickmyTextBox.Text = "Hello, World!"End SubPublic Shared Sub Main()Application.Run(New MainForm())End SubEnd ClassEnd Namespace```3. 代码解析上述代码创建了一个名为`MainForm`的窗体类。

VB扫雷小游戏一．编程目的二．编程思路1.新建command_up和label_down控件2.用load加载控件3.根据雷区的X、Y、以及难度进行随机布雷。

4.统计每一个label周围雷的数量并作为label的caption。

5.在单击command的时候显示label6.在右击command的时候进行标记7.在label上左右键同时按下的时候检查已标记雷的数量与label显示的数量是否一致。
