用VB.NET编写一个交通灯的程序
下面这个希望可以帮到你~交通灯
实例说明在本实例中，我们将制作一个具有交通灯效果的应用程序。程序运行后，交通灯不断地变化，可以通过按钮运行或停止程序。程序运行结果如图88-1所示。技术要点l 不断变换图片l 不断更改时间间隔 type="text/javascript" type="text/javascript" src=" "
实现过程■ 新建项目打开Visual Studio.NET，选择"新建项目"，在项目类型窗口中选择"Visual Basic项目"，在模板窗口中选择"Windows应用程序"，在名称域中输入"Traffic"，然后选择保存路径。单击"确认"。■ 添加控件向当前窗体添加一个Timer控件，用于控制交通灯变换的时间；三个Picture控件，分别装入相应的图片；一个Button按钮，用于控制交通灯。属性保持默认值。■ 添加代码Dim vv As BooleanDim updirec As BooleanPrivate Sub Command1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command1.Clickvv = Timer1.Enabledvv = Not vvTimer1.Enabled = vvIf vv ThenCommand1.Text = "开 始"ElseCommand1.Text = "停 止"End IfEnd SubPrivate Sub Timer1_Tick(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Timer1.TickStatic i As ShortSelect Case iCase 0Timer1.Interval = 3000picicon0.Visible = Truepicicon1.Visible = Falsepicicon2.Visible = Falsei = i + 1updirec = FalseCase 1Timer1.Interval = 1000picicon0.Visible = Falsepicicon1.Visible = Truepicicon2.Visible = False'Me.Icon = picicon(i).ImageIf updirec Theni = i - 1Elsei = i + 1End IfCase 2Timer1.Interval = 3000picicon0.Visible = Falsepicicon1.Visible = Falsepicicon2.Visible = Truei = i - 1updirec = TrueEnd SelectEnd Sub■ 运行程序单击菜单"调试|启动"或单击 图标运行程序。
用VB.NET编写一个程序 ：编一求阶乘的函数f(n),主调程序求组合数的程序，分别调用f(n),用来计算组合数的值
Private Sub Command1_Click()
Dim A, B, C
A = 10
B = 3
C = f(A) / (f(B) * f(A - B))
Print C
End Sub
Private Function f(n)
Dim I As Integer
f = 1
For I = 1 To n
f = f * I
Next I
End Function
用VB.NET编写以下程序。
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
Timer tm = new Timer();//实例化 timeer
static int timeS = 0; //设置静态变量记录秒数
TimeSpan ts = new TimeSpan(); //实例化 TimeSpan
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
tm.Interval = 1000; //设置 timeer 1000毫秒执行一次
tm.Tick += new EventHandler(timeer_Tick); //设置 timeer 运行事件
tm.Start(); // 启用 timeer
}
private void timeer_Tick(object sender, EventArgs e)
{
timeS += 1; //秒数 +1
ts = new TimeSpan(0, 0, timeS);
label1.Text = ts.Hours + ":" + ts.Minutes + ":" + ts.Seconds;
}
private void button2_Click(object sender, EventArgs e)
{
tm.Stop();
timeS = 0;
}
}
}
用vb.net编写的程序怎么封装?
你得意思是生成一个EXE文件吧？程序运行以后在bin\debug目录下面
VB.NET 2005编写定时关机程序
最近在网上搜索了一些关于实现关机 重启 注销的文章 发现大多介绍的是VB NET 用API实现这些功能 且在XPsp 环境下无法正常的关机与注销 而对于VB NET 的介绍几乎没有 本文章所涉及的知识点有
用实现关机 重启 注销功能 通过使用textbox与timer控件的结合编写定时器功能 为你的程序加上超链接
本篇文章具有一定的基础性和广泛的实用性 相信能够给 初学者带来一定的帮助
本文所使用的编程环境是Microsoft Visual Studio 首先打开 Visual Studio 在文件 (File) 菜单上 单击新建项目 (New Project) 在新建项目 (New Project) 对话框的模板 (Templates) 窗格中 单击 Windows 应用程序 (Windows Application) 单击确定 (OK)
具体步骤如下
首先在Form 窗体上添加一个Label 控件属性text设置为:今天: 然后分别添加 个button控件name分别为button button button 它们的text属性分别为 关闭计算机（启动定时器） 注销 重新启动
图
现在我们就需要为程序加上一个定时器了 这个定时器需要与textbox 控件相关联 输入正确时间格式后就可以启动定时功能了 然后我们需要在窗体上添加一个timer 一个textbox 控件 和一个RadioButton 控件 让它们保留默认值不变 其中 TextBox 控件的text属性设置为 : : RadioButton 控件text设置为 指定时间关机|时间格式 小时: 分钟: 秒如图 所示
图
以上界面工作基本完成现在需要输入代码了
双击窗体进入常规 声明Public Class Form 事件中
CODE
Imports System Runtime InteropServicesImports Microsoft VisualBasicPublic Class Form _ 调用系统参数Friend Shared Function GetCurrentProcess() As IntPtrEnd Function

Public Shared Sub PowerOff() DoExitWin((EWX_FORCE Or EWX_POWEROFF)) 关闭计算机End Sub
Public Shared Sub LogoOff() DoExitWin((EWX_FORCE Or EWX_LOGOFF)) 注销计算机End Sub
Dim entTime As Object 保存输入时间Dim xianzaiTime As Object 保存实时时间Dim startTime As Object 保存开始定时时间
注销button 按钮输入code
Private Sub Button _Click(ByVal sender As System Object
ByVal e As System EventArgs) Handles Button ClickLogoOff() 注销计算机End Sub
双击重新启动按钮button 输入code
Private Sub Button _Click(ByVal sender As System Object
ByVal e As System EventArgs) Handles Button Click
Reboot()
End Sub
双击关闭计算机按钮button 输入code
Private Sub Button _Click(ByVal sender As System Object
ByVal e As System EventArgs) Handles Button Click startTime = TimeOfDay If Not IsDate(TextBox Text) Then 用IsData函数判断输入的时间格式MsgBox( 你所输入的不是时间格式 ! 错误 ) ElseentTime = TimeValue(TextBox Text) End If Timer Enabled = True 启动定时器 Me WindowState = System Windows Forms FormWindowState Minimized 最小化窗体
End Sub
如图
图
双击timer 控件如图
图
输入代码
Private Sub Timer _Tick(ByVal sender As System Object
ByVal e As System EventArgs) Handles Timer Tick xianzaiTime = TimeOfDay If RadioButton Checked Then
If DateDiff(Microsoft VisualBasic DateInterval Second
xianzaiTime entTime) Then 用DateDiff函数判断是否到时间了
End IfEnd If
PowerOff() 关闭计算机End Sub
好了 基本上一个定时关机程序就完成了 接下来加一个超级链接吧！当然对于高手来说可能是废话 但是对于新手来说这也是必备的 这个超级链接当然是我们最喜欢的天极网开发频道了
先创建一个Label控件吧 把它托到窗体上 将text属性设置为天极网开发频道如图
图
接下来需要输入代码了 双击窗体Form
进入Public Class Form 事件
代码
Private Declare Function ShellExecute Lib shell dll
Alias ShellExecuteA (ByVal hwngnd As Integer
ByVal lpOperation As String ByVal lpFile As String
ByVal lpParameters As String ByVal lpDirectory As String
ByVal nShowCmd As Integer) As Integer
如图
图
双击刚才添加的label属性text:（天极网开发频道）中输入以下代码
Private Sub Label _Click(ByVal sender As System Object
ByVal e As System EventArgs) Handles Label ClickShellExecute( open CStr( ) CStr( ) )
End SubEnd Class
OK！全部搞定 按F 键运行如图 所示 选择相应选项后点击（关闭计算机启动定时器按钮）就可以了 现在程序将按照你所设定的时间而启动关闭计算机选项
