Count down timer

[iFrolox]

Hello, i need help making a count down timer that can support at least 100 Hours, i got this code but it only supports 24 hours.

Dim TimePlayer1 As Date

    Private Sub Button1_MouseClick(sender As Object, e As MouseEventArgs) Handles Button1.MouseClick
        If e.Button = Windows.Forms.MouseButtons.Left Then
            Select Case Me.Button1_Start.Text
                Case "Start"
                    Me.TimePlayer1 = Date.Now.AddMinutes((Me.TextHours.Text.ToString * 60) + (Me.TextMins.Text.ToString))

                    Me.Timer1.Start()
                    Me.Button1.Text = "Stop"
                Case "Stop"
                    Me.Timer1.Stop()
                    Me.Button1.Text = "Start"
            End Select
        End If
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If Me.TimePlayer1 < Date.Now Then
            Me.Timer1.Stop()

            MessageBox.Show("Time just finished.", "Time Out", MessageBoxButtons.OK, MessageBoxIcon.Information)
        Else
            Dim remainingTime As TimeSpan = Me.TimePlayer1.Subtract(Date.Now)
            Me.LabelTime1Display.Text = "Time: " & String.Format("{0:d2}:{1:d2}:{2:d2}", remainingTime.Hours, remainingTime.Minutes, remainingTime.Seconds)
        End If
    End Sub

Any help ?

Hmmm... Never used these before but when you debug me.TimePlayer1 what do you get?

Is it the full date and time value or just a time value? I suspect it is passing just a time value and substituting the current date hence you are stuck in a 24 hour period.

hello !
please check the attach sample project of count down counter .
here is a code ,
i have three textboxes , txtsec , txtmint , txthours. and a timer here is a code .

    Dim sec As Int16
    Dim mint As Boolean
    'use this code at the timer 
     sec = sec + 1
        txtSec.Text = sec
        If sec = 60 Then
            txtmint.Text = Val(txtmint.Text) + 1
            If txtmint.Text = 60 Then
                mint = True
                txtmint.Text = 0
            End If

            If txtmint.Text = 0 And mint = True Then
                txthr.Text = Val(txthr.Text) - 1
                mint = False
            End If
            sec = 0
            txtSec.Text = 0
        End If

set your timer interval according to your equirement . 1000 is equal to 1 sec.

@G: Yea exactly that, it works perfectly and i have a countdown of example: 10:58:23, then after a minute and a few seconds it would look like: 10:53:10, etc.. it works but like you said im stuck with the 24Hours.

@waqas: im trying to do the countdown and show it in a label in this format: 00:00:00

[M.Waqas Aslam]

Hi, had the same problem, solved it with this piece of code. All it realy does is countdown seconds. The rest of it is just to keep the format 00:00:00 in the label where the countdown

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        Dim sec, min, hrs As String
        secondstotal -= 1
        If secondstotal < 0 Then
            secondstotal = 59
            minutestotal -= 1
        End If
        If minutestotal < 0 Then
            minutestotal = 59
            hourstotal -= 1
        End If
        If countdown = 0 Then
            Timer1.Stop()
        End If
        sec = secondstotal.ToString()
        min = minutestotal.ToString()
        hrs = hourstotal.ToString()
        If sec.Length = 1 Then
            sec = "0" + sec
        End If
        If min.Length = 1 Then
            min = "0" + min
        End If
        If hrs.Length = 1 Then
            hrs = "0" + hrs
        End If
        Label1.Text = hrs + ":" + min + ":" + sec
    End Sub

time is shown. As it is it wil countdown from 99:59:59. You can adapt it for more

You will probably have to store your "target date and time" as a variable and on the tick event check if the date now is equal to the target date. This will allow you to go beyond the 24 hour period.

ok , i change my code little bit. please replace previous code with this one.

        sec = sec + 1
        txtSec.Text = sec
        If sec = 60 Then
            txtmint.Text = Val(txtmint.Text) + 1
            If txtmint.Text = 60 Then
                mint = True
                txtmint.Text = 0
            End If

            If txtmint.Text = 0 And mint = True Then
                txthr.Text = Val(txthr.Text) + 1
                mint = False
                If txthr.Text = 100 Then
                    Timer1.Enabled = False
                    txtSec.Text = 0


                End If
            End If
            sec = 0
            txtSec.Text = 0
        End If

Well i did it without any copy paste, since my original code could be easily changed by changing the computer's time i changed it to this:

Add 1 button, 1 timer, 1 label, and 2 textbox.

Rename 1 textbox to iHours_Text and the other to iMins_Text

This will be my declarations for the time:

    Dim iSecs As Integer = "0"
    Dim iMins As Integer = "0"
    Dim iHours As Integer = "0"

This is to add the hours, and the minutes and start the timer

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Me.iHours = iHours_Text.Text
        Me.iMins = iMins_Text.Text
        Me.Timer1.Start()
    End Sub

This will be my declarations to keep the 00:00:00 format:

    Dim iDisplaySecs As String = String.Empty
    Dim iDisplayMins As String = String.Empty
    Dim iDisplayHours As String = String.Empty

This will be to count down, let the 00:00:00 format and display to label:

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        If Me.iSecs > "00" Then
            Me.iSecs -= 1
        ElseIf Me.iSecs <= "00" Then
            If Me.iMins > "00" Then
                Me.iMins -= 1
                Me.iSecs = "59"
            ElseIf Me.iMins <= "00" Then
                If Me.iHours > "00" Then
                    Me.iHours -= 1
                    Me.iMins = "59"
                    Me.iSecs = "59"
                End If
            End If
        End If

        If Me.iHours < "10".ToString Then
            Me.iDisplayHours = "0" & Me.iHours.ToString
        Else
            Me.iDisplayHours = Me.iHours.ToString
        End If

        If Me.iMins < "10" Then
            Me.iDisplayMins = "0" & Me.iMins.ToString
        Else
            Me.iDisplayMins = Me.iMins.ToString
        End If

        If Me.iSecs < "10" Then
            Me.iDisplaySecs = "0" & Me.iSecs.ToString
        Else
            Me.iDisplaySecs = Me.iSecs.ToString
        End If

        Label1.Text = Me.iDisplayHours & ":" & Me.iDisplayMins & ":" & Me.iDisplaySecs

        If (Me.iHours) + (Me.iMins) + (Me.iSecs) < "1" Then
            Timer1.Stop()
            MessageBox.Show("Time's up")
        End If
    End Sub
