VB.NET中用label显示时间Label1.Text = "12时演示:"Now.ToString("yyyy-MM-dd hh:mm:ss")
Label2.Text = "24时演示:"Now.ToString("yyyy-MM-dd HH:mm:ss")
Label3.Text = "UTC时演示:"System.DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss")
Label4.Text = "时间为不补0:"Now.ToString("yyyy-MM-dd H:m:s")
Label5.Text = "时间戳:"CLng(System.DateTime.UtcNow.Subtract(New Date(1970, 1, 1, 0, 0, 0)).TotalMilliseconds).ToString
VB.NET用TIMER控件vb.net 毫秒时间戳我使用Visual Basic 2008 编写
1、新建2个窗体Form1和Form2
2、Form1窗体新建一个Button按扭和一个Timer1控件
3、打开Form1编写如下代码
Public Class Form1
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Form2.Show()
Me.Hide()'隐藏本窗体
Timer1.Enabled = False'使其只执行1次
End Sub
【包含vb.net 毫秒时间戳的词条】Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Enabled = True'能使用其实这个在属性窗口中更容易设置
Timer1.Interval = 2000 '毫秒 即2秒
End Sub
End Class
用VB.NET设计一个以秒为基本单位的表，并且显示在窗体上的步骤，并且给出关键代码是我以前自己设计的用来测试自己点钞速度用的，希望是你需要的
以下是窗体的全部代码
Public Class Form1
Dim StartFlag As Boolean = False
Dim secon As Integer
Dim minut As Integer
'空格
Private Sub Form1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
If e.KeyCode = Keys.Space Then
If StartFlag Then
StartFlag = False
Timer1.Enabled = False
If Val(Strings.Right(Label1.Text, 2))10 And Val(Strings.Right(Label1.Text, 2)) = 0 Then secon = 0 : minut = 0 : Label1.Text = "00:00" : Exit Sub
ListBox1.Items.Add(Label1.Text.ToString)
ListBox1.SelectedItem = ListBox1.Items.Count - 1
Label1.Focus()
Button1.Enabled = True
Label1.Text = "00:00"
secon = 0
minut = 0
Else
StartFlag = True
Timer1.Enabled = True
End If
End If
End Sub
'加载
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Clear()
Label1.Text = "00:00"
Button1.Enabled = False
secon = 0
minut = 0
Label1.Focus()
End Sub
'清空
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Button1.Enabled = False
ListBox1.Items.Clear()
Label1.Focus()
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
secon= 1
If secon = 60 Then
secon = 0
minut= 1
End If
Dim seconStr As String = secon
If seconStr.Length = 1 Then seconStr = "0"seconStr
Dim minutStr As String = minut
If minutStr.Length = 1 Then minutStr = "0"minutStr
Label1.Text = minutStr":"seconStr
Label1.Focus()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SeconSun As Integer
If ListBox1.Items.Count0 Then
For i = 0 To ListBox1.Items.Count - 1
Dim TemStr As String = ListBox1.Items.Item(i).ToString
Dim TemInt1 As Integer = Val(Strings.Right(TemStr, 2))
Dim TemInt2 As Integer = Val(Strings.Left(TemStr, 2))
Debug.Print(TemInt1.ToString)
Debug.Print(TemInt2.ToString)
SeconSun= TemInt1TemInt2 * 60
Debug.Print(SeconSun.ToString)
Next
TextBox1.Text = (SeconSun / ListBox1.Items.Count).ToString"秒"
End If
Label1.Focus()
End Sub
End Class
