如何节省数据库时间

问题描述

大家好，我是vb新手
我只想问一下如何将经过的时间存储到数据库中?

我有2种表格
在形式一中，我有一个计时器和一个按钮

hi guys im new in vb
i just want to ask if how can i store the elapsed time to my database?

i have 2 forms
in form one i have a timer and a button

Public Class Form1
    Public _elapseTimerRunning As Boolean = False
    Public _elapseStartTime As DateTime
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        _elapseStartTime = DateTime.Now
        _elapseTimerRunning = True

    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        End

    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Timer1.Interval = 1000
        Timer1.Enabled = True
    End Sub

    Public Sub Timer1_Tick(sender As Object, e As EventArgs)
        ''Form_Cert.Label5.Text = Now.ToString("h:mm:ss tt")
        If _elapseTimerRunning = True Then
            Dim elapsedtime = DateTime.Now.Subtract(_elapseStartTime)
            Form2.Label5.Text = String.Format("{0}hr : {1}min : {2}sec", elapsedtime.Hours, elapsedtime.Minutes, elapsedtime.Seconds)
        End If
    End Sub
End Class

现在，我要在表格2的标签5中显示所花费的时间
我想将数据保存到数据库后吗?

我该怎么办?
