[RESOLVED] Basketball Sports ClockI

[DJHotIce]

I'm working on an application that needs a counting down start stop clock, ability to be set to a specified time such as 20 minutes. I can prob figure out the code to that.

It does not have to be uberly time accurate, however, if possible, the ability to show the clock the clocks precision to a tenth of a second when under 1 minute.

so 59.9, 1.7, etc.

I searched some code on here, the code count downs accurately for a while, but I think the translation to format the clock is wrong, it counts down to random times.

Any idea's help, code?

Post the code you have so far. You sould be using a timer control set at an Interval of 100.

This is what I'm currently using.

Private Sub timeClock_Timer()
    Dim lTemp As Long
    Dim lTemp2 As Long
    intCounter = intCounter - 1000
    lTemp = intCounter
    lTemp = lTemp / 1000 'convert to seconds
    lTemp2 = lTemp
    lTemp = (lTemp / 60) Mod 60 'Minutes
    lTemp2 = (lTemp2 Mod 60) 'Seconds
    If lTemp2 < 10 Then
        lblTime.Caption = lTemp & ":0" & lTemp2
    Else
        lblTime.Caption = lTemp & ":" & lTemp2
    End If
    If intCounter = 0 Then
        timeClock.Enabled = False
        MsgBox "Times up"
    End If
End Sub

I'm using a basic enable/disable. I know from what I currently have the tenth of a second resolution is not going to work.

Here is a quick example of a count down timer. Format for time/seconds or whatever and your good to go.

Option Explicit

Private Sub Command1_Click()
    Timer1.Enabled = True
    Timer1.Interval = 100
End Sub

Private Sub Timer1_Timer()
    Static l As Long
    l = l + 100
    If 6000 - l <= 0 Then Timer1.Enabled = False
    Me.Caption = 6000 - l
End Sub

is my minute second code above flawed then?

How can I get the tenth second precision as seen on TV?

[RobDog888]

No, its fine I think. I was just too lazy to add all the extras in

[Code Doc]

Here's a slightly different approach:

Dim StartTime As Long, Mincount As Integer
Dim Minutes As String, Seconds As String
Const GameLength = 1200 ' Playing Time in Seconds

Private Sub Form_Load()
StartTime = Timer
Timer1.Interval = 100
End Sub

Private Sub Timer1_Timer()
If (Timer - StartTime) / (Mincount + 1) > 60 Then Mincount = Mincount + 1
Seconds = Format$(60 * (Mincount + 1) - (Timer - StartTime), "00")
If Seconds = "60" Then Seconds = "00"
If GameLength - (Timer - StartTime) > 60 Then
    Minutes = Format$((GameLength - (Timer - StartTime)) \ 60, "00:")
    Label1.Caption = Minutes & Seconds
ElseIf GameLength - (Timer - StartTime) > 0 Then
   Label1.Caption = Format$(60 * (Mincount + 1) - (Timer - StartTime), "00:00.0")
Else: Label1.Caption = "Game Over!"
End If
End Sub

I am sure you could simplify it a little, but it works. Be sure you set the game length at 120 seconds (two minutes) or longer to get an accurate initial clock reading. It switches over to split the second into tenths when one minute or less remains on the clock.

[Code Doc]

I realize that the post is marked resolved, but here is yet another approach using two timer controls: one for the first 19 minutes and the other for splitting the second when only one minute remains:

Dim StartTime As Double, StartSecond As Long
Const GameLength = 20 ' Length of basketball game in minutes

Private Sub Form_Load()
Timer1.Interval = 100
Timer2.Interval = 100
Timer2.Enabled = False
StartTime = Now
End Sub

Private Sub Timer1_Timer()
If GameLength - 1440 * (Now - StartTime) > 1 Then
    Label1.Caption = "Time Remaining: " & Format$(GameLength / 1440 - (Now - StartTime), "h:mm:ss")
Else: Timer1.Enabled = False
    Timer2.Enabled = True
    StartSecond = Timer
End If
End Sub

Private Sub Timer2_Timer()
If Timer - StartSecond < 60 Then
    Label1.Caption = "Time Remaining: " & Format$(60 - (Timer - StartSecond), "00:00.0")
Else: Label1.Caption = "Game Over!"
End If
End Sub

Note that the seconds clock kicks in and uses the Timer function for splitting seconds. The first clock uses Now rather than Timer. So, there is less chance that the clock would have trouble near midnight when Timer is invoked. Good Luck, DJ!
