vb简单的计算机源代码

VB简易计算器代码下面是一个简单的VB计算器代码，用于执行基本的加、减、乘、除运算。

```vbOption Strict OnPublic Class CalculatorPrivate Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.ClickDim num1 As Double = CDbl(txtNum1.Text)Dim num2 As Double = CDbl(txtNum2.Text)Dim result As Double = num1 + num2txtResult.Text = result.ToStringEnd SubPrivate Sub btnSubtract_Click(sender As Object, e As EventArgs) Handles btnSubtract.ClickDim num1 As Double = CDbl(txtNum1.Text)Dim num2 As Double = CDbl(txtNum2.Text)Dim result As Double = num1 - num2txtResult.Text = result.ToStringPrivate Sub btnMultiply_Click(sender As Object, e As EventArgs) Handles btnMultiply.ClickDim num1 As Double = CDbl(txtNum1.Text)Dim num2 As Double = CDbl(txtNum2.Text)Dim result As Double = num1 * num2txtResult.Text = result.ToStringEnd SubPrivate Sub btnDivide_Click(sender As Object, e As EventArgs) Handles btnDivide.ClickDim num1 As Double = CDbl(txtNum1.Text)Dim num2 As Double = CDbl(txtNum2.Text)If num2 = 0 ThenMessageBox.Show("除数不能为0！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error)ElseDim result As Double = num1 / num2txtResult.Text = result.ToStringEnd IfEnd Sub```此代码创建了一个简单的窗体应用程序，其中包含两个文本框用于输入两个数字，四个按钮用于执行不同的计算操作，以及一个文本框用于显示结果。

vb编程代码大全Visual Basic (VB) 是一种广泛用于软件开发的高级编程语言，可以用于开发 Windows 应用程序、Web 应用程序、数据库应用程序等。

在本文中，将介绍一些常用的 VB 编程代码，帮助初学者快速入门和提高编程水平。

一、基本数据类型1. 整型数据在 VB 中，整型数据可以使用 Integer 类型表示，范围为 -32,768 到32,767。

定义整型变量的代码如下：```Dim num As Integernum = 10```2. 浮点数据浮点数据可以使用 Single 或 Double 类型表示，分别表示单精度浮点数和双精度浮点数。

定义浮点变量的代码如下：```Dim num As Singlenum = 3.143. 字符串数据字符串数据可以使用 String 类型表示，可以存储文本数据。

定义字符串变量的代码如下：```Dim str As Stringstr = "Hello, World!"```二、控制流程1. If...Then...Else 语句If...Then...Else 语句用于根据条件执行不同的代码块。

例如：```Dim num As Integernum = 10If num > 0 ThenMsgBox("Num is positive.")ElseMsgBox("Num is negative.")End If2. For 循环For 循环用于重复执行一段代码。

例如：```For i = 1 To 10MsgBox(i)Next i```3. Do While 循环Do While 循环在满足条件时执行代码块。

例如：```Dim i As Integeri = 1Do While i <= 10MsgBox(i)i = i + 1Loop```三、数组1. 一维数组一维数组在 VB 中用于存储相同类型的多个元素。

用VB编写一个简单计算器一、功能：实现简单的加减乘除功能，C归零，CE取消输入，%计算并显示第一个操作数的百分比。

二、控件：1个label，20个commandbutton。

三、计算器运行界面：四、详细代码：Option ExplicitDim Op1, Op2 '前面输入的操作数Dim DecimalFlag As Integer '小数点仍然存在吗？Dim NumOps As Integer '操作数个数Dim LastInput '指示上一次按键事件的类型Dim OpFlag '指示未完成的操作Dim TempReadout' C (取消) 按钮的Click 事件过程' 重新设置显示并初始化变量Private Sub Cancel_Click()Readout = Format(0, "0.")Op1 = 0Op2 = 0Form_LoadEnd Sub' CE (取消输入) 按钮的Click 事件过程Private Sub CancelEntry_Click()Readout = Format(0, "0.")DecimalFlag = FalseLastInput = "CE"End Sub' 小数点(.) 按钮的Click 事件过程' 如果上一次按键为运算符，初始化readout 为"0."；' 否则显示时追加一个小数点Private Sub Decimal_Click()If LastInput = "NEG" ThenReadout = Format(0, "-0.")ElseIf LastInput <> "NUMS" ThenReadout = Format(0, "0.")End IfDecimalFlag = TrueLastInput = "NUMS"End Sub' 窗体的初始化过程' 设置所有变量为其初始值Private Sub Form_Load()DecimalFlag = FalseNumOps = 0LastInput = "NONE"OpFlag = " "Readout = Format(0, "0.")'Decimal.Caption = Format(0, ".")End Sub' 数字键(0-9) 的Click 事件过程' 向显示中的数追加新数Private Sub Number_Click(Index As Integer)If LastInput <> "NUMS" ThenReadout = Format(0, ".")DecimalFlag = FalseEnd IfIf DecimalFlag ThenReadout = Readout + Number(Index).CaptionElseReadout = Left(Readout, InStr(Readout, Format(0, ".")) - 1) + Number(Index).Caption + Format(0, ".")End IfIf LastInput = "NEG" Then Readout = "-" & ReadoutLastInput = "NUMS"End Sub' 运算符(+, -, x, /, =) 的Click 事件过程' 如果接下来的按键是数字键，增加NumOps。

开发实例源代码
以下是一个简单的 开发实例源代码，用于创建一个 Windows 应用程序，显示一个带有按钮的窗口，当点击按钮时会弹出一个消息框。

```vb
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
MessageBox.Show("你点击了按钮!")
End Sub
End Class
```
在这个示例中，我们创建了一个名为 `Form1` 的类，其中包含一个名为 `Button1` 的按钮和一个名为 `Button1_Click` 的事件处理程序。

当点击按钮时，`Button1_Click` 事件处理程序将执行，弹出一个消息框显示 "你点击了按钮!"。

这只是一个简单的示例，你可以根据自己的需求进行扩展和修改。

提供了丰富的工具和功能，帮助你创建各种类型的应用程序，包括 Windows 桌面应用程序、Web 应用程序、移动应用程序等。

如果你有特定的需求或想要进一步学习 开发，我建议你参考相关的教程、书籍或在线资源，以获取更详细和深入的信息。

vb编程代码大全VB（Visual Basic）是一种易于学习和使用的编程语言，广泛应用于Windows平台的软件开发。

VB编程通过编写和执行代码来实现任务，可以用于创建各种类型的应用程序，包括窗体应用程序、控制台应用程序、Web应用程序等。

本文将介绍一些常用的VB编程代码，帮助读者快速入门和掌握VB编程技巧。

一、VB基本语法在开始编写VB代码之前，我们先来了解一些基本的VB语法规则。

1. 注释VB中的注释用于解释代码的作用，不会被编译器执行。

注释可以是单行注释（以“'”开头）或多行注释（以“/*”开始，“*/”结束）。

示例：' 这是一个单行注释/*这是一个多行注释可以跨越多行*/2. 变量声明在VB中，变量需要先声明后使用。

变量的声明可以包括数据类型和变量名称。

示例：Dim x As Integer '声明一个整型变量x3. 变量赋值在VB中，可以使用赋值语句将一个值赋给变量。

示例：x = 10 '将变量x赋值为104. 运算符VB支持常见的运算符，包括算术运算符、比较运算符和逻辑运算符等。

示例：Dim a As Integer, b As Integera = 10b = 5Dim c As Integerc = a + b '加法运算c = a - b '减法运算c = a * b '乘法运算c = a / b '除法运算c = a Mod b '取余运算c = a > b '比较运算c = (a > 0) And (b > 0) '逻辑运算5. 控制结构VB中的控制结构包括条件语句和循环语句。

条件语句通过判断条件来选择不同的执行路径。

循环语句可以重复执行一段代码。

示例：If condition Then' 执行语句块1ElseIf condition2 Then' 执行语句块2Else' 执行语句块3End IfFor i = 1 To 10' 执行循环体Next i以上是VB的基本语法规则，通过掌握这些语法，可以编写简单的VB程序。
