You will need a timer control.

Create a new project and add a timer, label and button:

Option Explicit

Private startTime As Date

Private Sub Form_Load()
    Timer1.Interval = 333 ' update counter 3 times a second (adjust to your liking)
    Timer1.Enabled = False
End Sub

Private Sub Command1_Click()
    startTime = Now
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    Label1.Caption = DateDiff("s", startTime, Now)
End Sub

Im sure if you search around, you will find many ppl saying how inaccurate the timer is.

If dead accuracy is not that much of an issue for you, then the timer as suggested above is perfect.

If accuracy is important, then i highly reccomend ccrptimer. It was developed by  Karl E. Peterson who is one of microsofts Most Vaulable Professionals. I only using the library now, its fantastic.

The other great thing about it... its not a control, its a library, meaning you dont need one on each form u need a timer, you dont even need a form at all.

Its available here: http://ccrp.mvps.org/index.html?controls/ccrptimer6.htm 

Its very simple to use and has a sample project.

If you want any help using it, just let me know.

Sub DelayPre(preset)
 'delay in seconds.000

    Dim start#
    Dim Check#
    start = Timer
    Do Until Check >= start + preset
        DoEvents
        Check = Timer
    Loop
End Sub

Sub Command1_Click()
Dim x as Long
x = 0
   Do
      DelayPre(1)
      x = x + 1      
      Label1.Caption = x
   DoEvents
   Loop
End Sub

I need to put the

Doevents command

in your code where is
the correct place to put this in.

Dim a As Integer
Private Sub Form_Load()
    Timer1.Interval = 1000
    Timer1.Enabled = False
End Sub

Private Sub Command1_Click()
    a = 0
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    a = a + 1
    Label1.Caption = a
End Sub

no need do events
it work fine

how Can i get this function to display as h m s  : hours minutes seconds

thanks

Dim s As Integer
Dim m As Integer
Dim h As Integer

Private Sub Form_Load()
    Timer1.Interval = 1000
    Timer1.Enabled = False
End Sub

Private Sub Command1_Click()
    s = 0
    m = 0
    h = 0
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    s = s + 1
   
    If s = 60 Then
        m = m + 1
        s = 0
    End If
   
    If m = 60 Then
        m = 0
        h = h + 1
    End If
   
    Label1.Caption = h & ":" & m & ":" & s
End Sub

or this code

Dim a As Integer

Private Sub Form_Load()
    Timer1.Interval = 1000
    Timer1.Enabled = False
End Sub

Private Sub Command1_Click()
    a = 0
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
   
    Dim m, s, h As Integer

    a = a + 1
    m = Int(a / 60)
    s = a - (m * 60)
    h = Int(m / 60)
    m = m - (h * 60)
   
    Label1.Caption = h & ":" & m & ":" & s
   
End Sub

or this

dim StartTime


Private Sub Form_Load()
    Timer1.Interval = 500
    Timer1.Enabled = False
End Sub

Private Sub Command1_Click()
    StartTime = now
    Timer1.Enabled = True
End Sub


private sub Timer1_Timer()
    Label1.caption= Format$(Now - starttime, "HH:MM:SS")
End Sub

just reset StartTimer to now to start again

Your code display a result of

0:0:0 format

can you do a

00:00:00 format

apart from this that should be it

yeah

Label1.Caption = Right("0" & h, 2) & ":" & Right("0" & m, 2) & ":" & Right("0" & s, 2)

Ok thankyou expert

Well Done
