Display Sum Total Of Listview Items

Question

Can anyone help me with displaying Sum Total of Listview Items in a label. I tried this:
Dim dblTotal as Double = 0
Dim dblTemp As Double
For Each lvItem As ListViewItem In lvwTemps.Items
If Double.TryParse(lvItem.SubItems(2).Text, dblTemp) Then
dblTotal += dblTemp
End If
Next
Label2.Text = dblTotal
but it's just giving me 0 in the label

Hi
Seems like you might have a second VB Editor open? In any case, save the Project, close down VB and rerun will probably fix it.

Yes, that worked but it gives me an unreal number .. 
You'll need to take the unit into consideration and convert all values to the same unit, for example, MB:
Dim dblTotal As Double = 0
Dim dblTemp As Double
For Each lvItem As ListViewItem In lvwTemps.Items
Dim values() As String = lvItem.SubItems(2).Text.Split(" "c)
If Double.TryParse(values(0), dblTemp) Then
If values(1) = "MB" Then
dblTemp *= 1000000
ElseIf values(1) = "KB" Then
dblTemp *= 1000
End If
dblTotal += (dblTemp / 1000000)
End If
Next
Label2.Text = dblTotal
