VB计时器怎么用

3个标签,2个按钮,1个计时器控件 Private Sub Command1_Click() '开始/暂停 If Timer1.Enabled = True Then Timer1.Enabled = False Else Timer1.Enabled = True End If End Sub Private Sub Command2_Click() '停止清0 Label1 = "0" Label2 = ...

定义一个全局变量code dim code as string 按拨号按钮时将输入框内容保存在code中 private sub command1_click() code=text1.text end sub 按重拨键时将code的内容恢复到输入框 private sub command2_click() text1.text=code end sub

窗体上放一个Label,三个Command按钮: Dim h As Integer, m As Integer, s As Integer, ms As IntegerPrivate Sub Command1_Click()Timer1.Enabled = TrueTimer1_TimerEnd SubPrivate Sub Command2_Click()Timer1.Enabled = FalseEnd SubPrivat...

Private Sub Form_Load() Timer1.Interval = 1000 Label1.Caption = "0" End Sub Private Sub Timer1_Timer() Label1.Caption = Label1.Caption + 1 Beep End Sub

窗体加一个timer控件,interval属性设为60000(1分钟),代码区写以下代码 Dim count As Integer '用来记数,全局变量 Private Sub Timer1_Timer() If count = 30 Then '你要执行的语句 count = 0 Else count = count + 1 End If End Sub

Private Sub Command1_Click() Timer1.Enabled = True End Sub Private Sub Command2_Click() Timer1.Enabled = False End Sub Private Sub Command3_Click() Timer1.Enabled = False Label1.Caption = 0 End Sub Private Sub Form_Load() Timer...

控制台调用Timer和窗体是类似的。首先在项目引用里面加入System.Windows.Forms程序集,然后在代码顶部引入命名空间: Imports System.Windows.Forms 在控制台的Module中声明一个计时器: Private WithEvents Timer1 As New Timer() 把计时器的Ti...

Dim t As DatePrivate Sub Command1_Click() Timer1.Interval = 1000 t = TimeEnd SubPrivate Sub Timer1_Timer() Label1.Caption = CDate(Time - t) BeepEnd Sub

我认为你是想实现这样的功能:进入程序运行界面,点击开始按钮,实现label1自动计时。对吗? 首先,在程序设计界面添加Timer控件、Button控件和Label控件,设置其对应属性。 (1)timer控件属性: Name-timer ,Enable-false ,interval-事件频...
