I need to display a timer ticking down.
Example:
11h:52m:39s to 00h:00m:00s
How can I do this?
Thanks,

Hi,

You can try something like this. I would use the timer in the
componet tab with an interval of 1000.

http://msdn.microsoft.com/msdnmag/issues/04/02/TimersinNET/default.aspx

Private Sub Timer1_Elapsed(ByVal sender As System.Object, ByVal e As
System.Timers.ElapsedEventArgs) Handles Timer1.Elapsed

Static ts As New TimeSpan(0, 0, 10) ' hours, minutes, seconds

Dim tsZero As New TimeSpan(0, 0, 0)

ts = ts.Subtract(New TimeSpan(0, 0, 1))

If ts.Equals(tsZero) Then

Timer1.Enabled = False

MessageBox.Show("Done")

End If

Me.Text = ts.ToString

End Sub

Drop a timer (system.windows.forms.timer) and a lable from the toolbox on
the form. Add this Code:

Private m_EndDateTime As Date

'to start the timer:
m_EndDateTime = Date.Now.AddHours(0.01)
Timer1.Start()

'Tick handler:
Private Sub Timer1_Tick( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Timer1.Tick

Dim ts As TimeSpan

ts = m_EndDateTime.Subtract(Date.Now)
If ts.Ticks <= 0 Then
Label1.Text = "your time is up!"
Timer1.Stop()
Else
Label1.Text = String.Format( _
"{0:00}h:{1:00}m:{2:00}s", _
ts.Hours, ts.Minutes, _
CInt(Math.Ceiling(ts.Seconds + ts.Milliseconds / 1000)) _
)
End If

End Sub
