Question

我使用命令

从mysql数据库中读取数据

   vrijeme = myData.Item(2)           ' translation vrijeme = time
           ime = "Dobrodosli " & myData.Item(0) & ""  ' translation ime = name
           GameForma.Show()

之后我将vrijeme存储到文本框中

txtvrijeme.text = vrijeme

然后我在表单上添加计时器控件，并希望从文本框中的时间倒计时到0 .. 文本框中的时间格式为00:00:00

无论如何，如果有人想要帮助的话，整个项目都会在.rar中设置连接字符串和所有需要的东西 Dropbox：https://www.dropbox.com/s/maxmxeak0cr353q/PocetnaVerzija.rar

解决方案是。从值

中读取数据

    hours = txtTimefromDB.Text.Substring(0, 2)
    minutes = txtTimefromDB.Text.Substring(3, 2)
    sec = txtTimefromDB.Text.Substring(6, 2)

开始递减

Private Sub tmrCountdown_Tick(sender As Object, e As EventArgs) Handles tmrCountdown.Tick
    sec = sec - 1
    If sec = 0 Then
        minutes = minutes - 1
        sec = 60
    ElseIf minutes = 0 Then
        hours = hours - 1
        minutes = 60
    End If
    txtTimefromDB.Text = "" & hours & ":" & minutes & ":" & sec
End Sub

定时器，时间码，时间格式倒计时
