vb小程序设计实例

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。

VB程序代码(简单小程序)

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小程序代码实例

VB小程序代码实例VB小程序是一种基于Visual Basic语言开发的应用程序，它可以在Windows 操作系统上运行。

本文将为您提供一个VB小程序代码实例，帮助您了解如何编写和运行一个简单的VB小程序。

代码实例如下：```vbImports SystemPublic Class HelloWorldPublic Shared Sub Main()Console.WriteLine("Hello, World!")Console.ReadLine()End SubEnd Class```上述代码是一个经典的“Hello, World!”程序，它会在控制台输出一条问候语，并等待用户按下回车键。

下面是代码解释：- `Imports System`：这个语句告诉编译器我们将使用System命名空间中的类和方法。

- `Public Class HelloWorld`：这是一个公共类的声明，类名为HelloWorld。

- `Public Shared Sub Main()`：这是程序的入口点，它是一个公共静态方法，程序从这里开始执行。

- `Console.WriteLine("Hello, World!")`：这行代码会在控制台输出一条问候语。

- `Console.ReadLine()`：这行代码会等待用户按下回车键，以便程序暂停执行。

您可以将上述代码复制到一个文本编辑器中，并将文件保存为`.vb`扩展名。

然后，使用VB编译器将其编译为可执行文件，并在Windows操作系统上运行。

这个简单的VB小程序只是一个入门示例，您可以根据自己的需求和兴趣编写更复杂的VB小程序。

VB语言具有丰富的特性和功能，可以用于开发各种类型的应用程序，包括图形用户界面（GUI）应用程序、数据库应用程序、Web应用程序等。

希望这个VB小程序代码实例能够帮助您入门VB编程，并为您今后的学习和开发提供一些参考。

修改成功后VB编写会计实用小程序

今天的灵感：
最近学会计，看到同事用计算器算数，总是用一个数除以1.03（算税的）就有这么个灵感，不知道编出来会不会有用！
主要实现的功能就是输入一个数字，将这个数字除以1.03在第二个文本框中输出，然后将输入数减去文本框二里的数字的值输出在第三个文本框中，再放二个按钮，一个是退出按钮，一个是清除按钮。

程序设计起来很简单，如果有人需要，我把他写出来供大家参考。

输入数字：
N=val(text1.text)
T ext2.text=n/1.03
T ext3.text=n-text2.text
清除按钮：
T ext1.text=””
T ext2.text=””
T ext3.text=””
关闭按钮：
End
大家觉得怎么样呢？呵呵！
但是中间有错误，清除不了，请高手指导一下！
请教高人后，清除钮下的程序改了一下就可以实现了！！
N=val(text1.text)
T ext2.text=n/1.03
T ext3.text=n-text2.text
如果想把输出的数四舍五入到二位小数点，请用format（数字，“0.00”）语句完成。

VB代码VB小程序：通过枚举进程显示所有进程、隐藏进程、进程路径

VB代码VB小程序：通过枚举进程显示所有进程、隐藏进程、进程路径本小程序采用枚举进程的方法，显示所有进程，也能显示隐藏进程。

同时，能显示进程的完整路径。

有意思的是，一些已经结束的进程，同样可以显示。

用VB编了一个小程序来实现电脑抽奖的小功能

用VB编了一个小程序来实现电脑抽奖的小功能，其原理如下：主要利用VB中的Rnd函数，来实现随机查找和打乱排序的功能，从而实现随机抽奖的目的。

Rnd函数的语法结构是Rnd[(number)]，可选的number参数是 single或任何有效的数值表达式。

Rnd函数返回小于1但大于或等于0的值。

number 的值决定了 Rnd 生成随机数的方式。

为了生成某个范围内的随机整数，可使用以下公式：Int((upperbound － lowerbound ＋ 1) × Rnd ＋ lowerbound)这里，upperbound 是随机数范围的上限，而 lowerbound 则是随机数范围的下限。

另外，程序中还使用了INI文件，Windows INI文件,可解释为Windows初始化文件。

它是一种专门用来保存应用程序初始化信息和运行环境信息的文本文件。

ini文件是一种文本文件,它可以通过Notepad等文本编辑器进行编辑。

ini文件具有特定的格式。

一个INI 文件是由若干个段(section)组成的,每个段中包含若干关键字(key)及相应的值(value)。

创建应用程序自己的INI文件,通过INI文件保存应用程序的一些运行环境信息,然后在程序中读取INI文件中的设置信息并据以处理。

一旦程序的运行环境需要变更,则可以通过直接修改INI文件，或在程序中提供专门的界面间接地修改INI文件来保证程序的可用性。

1.打印负数并分别计算正负数只和：有如下10个数：-2，73，82，-76，-1，24，321，-25，89，-20(也可以定位其他数值) 打印出其中的每个负数，分别计算并输出正数和负数的和。

程序如下：Sub Form_Click()Dim number AS IntegerNegativeSum=0:PostiveSum=0For i=1 To 10number=InputBox("Enter data: ")If number<0 ThenPrint number;NegativeSum=NegativeSum+numberElsePostiveSum=PostiveSum+numberEnd IfNext iprintprint "NegativeSum=";NegativeSumPrint "PostiveSum=";PostiveSumEnd Sub2.打印九九表：在窗体上打印九九表：程序如下：Print Sub Form_Click()FontSize=12Print Tab(30);"9*9 Table"Print:Print '输出两个空行Print "* ";For i=1 To 9Print Tab(i*6);i; '打印横行序号Next iFor j=1 To 9Print j;" "; '打印竖行序号For k=1 To jtemp=j*kPrint Tab(k*6);temp;" "; '打印乘积Next kPrint '输出一个空行Next jEnd Sub3.打印人员名册打印人员名册:Private Sub Form_Click()Print:PrintFontName="魏碑"FontSize=16Print "姓名";Tab(8);"年龄";Tab(16);"职务";Tab(24);"单位";Tab(32);"籍贯"PrintPrint "张得功";Tab(8);"25";Tab(16);"科长";Tab(24);"劳动科";Tab(32);"北京"Print "李德生";Tab(8);"32";Tab(16);"处长";Tab(24);"科研处";Tab(32);"上海"End Sub4.单选按钮设置字体类型和大小单选按钮设置字体类型和大小:在窗体上画出两个框架，每个框架内分别画两个单选按钮，然后画两个命令按钮和一个文本框。

编写时间过程如下：Ptivate Sub Form_Load()Form1.Caption="框架用法示例"Command1.Caption="确定"Command2.Caption="结束"Frame1.Caption="字体类型"Frame2.Caption="字体大小"Option1.Caption="魏碑"Option2.Caption="幼圆"Option3.Caption="16"Option4.Caption="24"Text1.Text="Visual Basic 程序设计"End SubPrivate Sub Command1.Click_()If Optoion1 ThenText1.FontName="魏碑"ElseText1.FontName="幼圆"End IFIf Option3 ThenText1.FontSize=16ElseText1.FontSize=24End IfEnd SubPrivate Sub Command2.Click_()EndEnd Sub5.计算存款利息计算存款利息:本金p为10000，年利率为0.125，每年计息一次，求10年的本利和是多少。

Sub Form_Click()Dim p As Currencyp=10000:r=0.125t=1AgainIf t>10 Then GoTo 100i=p*rp=p+it=t+1GoTo Again100Print pEnd Sub说明：这里的“Again：”是标号，“100”是行号。

6.交换两个列表框的项目交换两个列表框的项目。

其中一个列表框的项目按字母升序排列，另一个列表框的项目按项目加入的先后顺序排列。

当双击某个项目时，该项目从列表框中消失，并出现在在另一个列表框中：Private Sub Form_Load()List1.FontSize=14List2.FontSize=14List1.AddItem "IBM"List1.AddItem "Compad"List1.AddItem "HP"List1.AddItem "FUJI"List1.AddItem "Digital"List1.AddItem "长城"List1.AddItem "联想"List1.AddItem "Canon"List1.AddItem "四通"List1.AddItem "Acer"List1.AddItem "Nec"List1.AddItem "NCR"End SubPrivate Sub List1_DbClick()List2.AddItem List1.TextList1.RemoveItem List1.ListIndexEnd SubPrivate Sub List2_DbClick()List1.AddItem List2.TextList2.RemoveItem List2.ListIndexEnd Sub7.交换图片交换两个图片框中的图形：在窗体上建立三个图片框Picture1、Picture2、Picture3，其中两个在上，一个在下。

Private Sub Form_Click()'交换位图Picture3.Picture=Picture1.PicturePicture1.Picture=Picture2.PicturePicture2.Picture=Picture3.Picture'把第三个图片框设置为空Picture3.Picture=LoadPicture()End SubPrivate Sub Form_Load'装入位图Picture1.Picture=LoadPicture _("C:\Documents and Settings\All Users\Documents\My Pictures\1.jpg") '可自行改变路径Picture2.Picture=LoadPicture _("C:\Documents and Settings\All Users\Documents\My Pictures\2.jpd") '可自行改变路径End Sub8.冒泡排序从键盘上输入10个整数，用冒泡法排序（Bubble Sort）法对这十个数从小到大排序：在窗体上建立一个命令按钮，并把Caption属性设置为“Click Here to Start”编写程序如下：Sub Command1_Click()Static number(1 To 10) AS Integer '定义数组number为整形Msg$="Enter Number for Sort:"MsgStile$="Sort Demo"For i%=1 To 10number(i%)=InputBox(Msg$,MsgTile$)Next i%For i%=10 To 2 Step -1For j%=1 To i%-1If number(j%)=number(j%+1) Thent=number(j%+1)number(j%+1)=number(j%)number(j%)=tEnd IfNext j%Next i%For i%=1 To 10Print number(i%)Next i%End Sub9.判断0~9数据类型--奇数或偶数判断字母大小写及0~9数据类型--奇数或偶数:Sub Form_Click()Dim Msg,UserInputMsg="Please enter a letter or number from 0 though 9." UserInput=InputBox(Msg)If Len(UserInput)<>0 ThenSelect Case Asc(UserInput) '返回ASCII码Case 65 To 90 '大写字母Msg="You entered the uppercase letter"Msg=Msg&Chr(Asc(UserInput))&"!"Case 97 To 122 '小写字母Msg="You entered the lowercase letter"Msg=Msg&Chr(Asc(UserInput))&"!"Case ElseMsg="You did not enter a letter or a number."End SelectElseSelect Case CDbl(UserInput) '转换为双精度数值Case 1,3,5,7,9Msg=UserInput&"is an odd number" '奇数Case 0,2,4,6,8Msg=UserInput&"is an odd number" '偶数Case Else '出界Msg="You entered a number ouside"Msg=Msg&"the requested range"End SelectEnd IfMsgBox MsgEnd Sub10.判断100~200的所有偶数可以分解为两个素数之和判断100~200的所有偶数可以分解为两个素数之和。
