Hey guys is there any one can help me about this code? I want to Subtract
the value of Listview SubsItem if the String Format in time span got 59
it will automatically subtract 1 for subitem tag

Private TimeLaps As Date
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim remainingTime As TimeSpan
For Each itm As ListViewItem In ListView1.Items

If CDate(itm.Tag) > Date.Now Then

remainingTime = CDate(itm.Tag).Subtract(Date.Now)

itm.SubItems(1).Text = String.Format("{0:d2}:{1:d2}:{2:d2}", _
remainingTime.Hours, _
remainingTime.Minutes, _
remainingTime.Seconds)


If itm.Tag(String.Format("{2:d2}").ToString = 59) Then ' <======== This part is the error
itm.SubItems(2).Tag = -1 '<=== and this part of code i want to subtract the text inside of the subitem(2) is
'the total minutes of timespan running.. if the timespan seconds string is 59
'then it will auto deducted the remaining minutes sample 60 minute then deduct 1
'so then remaining minutes left is 59

End If

End If


Next
End Sub

What is the 'View' mode of your ListView? Details?

Why you are using Tag property of listview item and subitem? Did you assign the DateTime to Tag property of ListView items elsewhere in the code?

Show us the details about your code.
