'                   i need to run the the time , in the decreasing order
'Label1.text =  with time count in decreasing order &"Left "
            End If

currentdate = Date.Now.ToString("MM/dd/yyyy")
            Dim diffdbdate As DateTime = dr.Item("date")
            Dim diffdate As Integer
            diffdate = DateDiff("d", currentdate, diffdbdate)
            Dim countdate As String = Replace(diffdate, "-", "")
            If currentdate > diffdbdate Then
                Label1.text =  countdate & "days Before"

Timespan helps you to do that... try this..

TimeSpan tsRemaining = EndDate - DateTime.Now;

ElseIf countdate = 1 Then

Basically timespan, if it is executed continously with some set of interval,, you get the effect of decreasing time...if you use AJAX extension , use timer control , and start the timer in

ElseIf countdate = 1 Then
        Timer1.Interval = 1000
         Timer1.Enabled=true
  End If

protected void Timer1_Tick(object sender, EventArgs e)
    {
          Dim tsRemaining As TimeSpan = diffdbdate - currentdate
                label1.text =tsRemaining.ToString() & "Left"
    }

                       return new Date(matches[1], matches[2] - 1, matches[3], matches[4], matches[5], matches[6]);

Hi,
Its really hard right...ok i can point to a user control which does everything for us. Add the control to your toolbox, and follow simple instruction to get remaining time.
There is a good sample for better understanding....

Remember: This uses the timespan as we discussed above..i think you can deduce a timespace with two dates.
