Get Sum Total of Column in Listview

I need to get Sum total of numeric data in in column



Private Sub cmdLoad_Click()
Dim itm As ListItem
Itemcount = lv.ListItems.Count
Dim a As String, b As String, C As String
Open App.Path & "\Converted.txt" For Input As #1
Do Until EOF(1)
Input #1, a, b, C
Set itm = lv.ListItems.Add(, , a)
itm.SubItems(1) = b
itm.SubItems(2) = C
' should I place code here and what code?
Loop


Close #1
' or here maybe a For loop to loop through though I am not
' sure just how to write the loop
' I was thinking something like
ItemCount = lv.Listitems.Count
For i = 1 to ItemCount
' some code here not sure what
Next i
End Sub


Need Help on this one

Either works, but I'd suggest you do the totals after making changes/updates to the listview through a called function.

That way, you can create a reusable function which has as parameters; listview object, column number. You can even pass a range to the function if you want to say total of items 10-15. Then the function returns the total.

Yes that sounds like something I will definately use on another Listview in another section of my App... but this one simply needs to give the Sum Total of the Subitems(1) column

Any idea what the code is for this?

VB Code:

Dim lngIndex As Long
    Dim lngTot As Long
    
    For lngIndex = 1 To lv.ListItems.Count
        lngTot = lngTot + lv.ListItems(lngIndex).SubItems(1)
    Next
    
    MsgBox lngTot

Yes this works great... I also found that placing code in the Do Until loop works as well.

such as

iSubTotal = iSubTotal + Val(b)
lblConv.Caption = iSubTotal
Thank you I am going to use the For loop it will come in handy for other operations in my app.

Now to find my next hill to climb..

I am trying to find a way to Change the name of the first column when a user Clicks new date on DTPicker (known in my app as DTP)

I can at Formload name it well actually it adds it but I need while running user clicks new Date it puts in the Columnheader title the results of Format(DTP.Value, "MMMM, yyyy") when DTP date is selected by user

ie March 2004 or April 2004

thanx again off to my searches
