Scroll the ListView

[miben]

I have a listview that is being populated with about 6000 items...

Dim recItems As Recordset
Dim intCount As Integer
Dim intItem As Integer
Dim lstItem As ListItem
Dim lstColumn As ColumnHeaders
Dim intColumn As Integer

With dbsData
    Set recItems = .QueryDefs("Debtor Count").OpenRecordset
    intCount = recItems!Count
    set recItems = .QueryDefs("Debtor List").OpenRecordset
End With

For intItem = 1 To intCount
    'Adds the item to the list
    Set lstItem = frmForm.vewitems.ListItems.Add()
    With lstItem
        .SmallIcon = CInt(recItems!Image)
        .Icon = CInt(recItems!Image) - 2
        .Key = recItems!Id
        .Text = recItems!Name
        'Adds the subitems
        Set lstColumn = frmForm.vewitems.ColumnHeaders
        For intColumn = 2 To lstColumn.Count
            .SubItems(intColumn - 1) = "" & _
                recItems.Fields (lstColumn(intColumn).Key)
        Next
        .Ghosted = recItems!Deleted
    End With
    recItems.MoveNext 'Next record
Next

This takes a few seconds. I found a way to make it faster. I want to add only the first visible items to the listview and add blank items for the rest. As I scroll the listview, I want to be able to add the details for the blank items.

The problem is, there is no scroll event for the listview. Does anyone know how to execute code when someone scrolls the listview?

I dunno about the listview scrolling event, but if you
want it faster, try this :

Dim anyArray

With dbsData
    Set recItems = .QueryDefs("Debtor Count").OpenRecordset
    intCount = recItems!Count
    set recItems = .QueryDefs("Debtor List").OpenRecordset
End With
anyArray = recItems.GetRows

that way your connection will be close right away and
you wont have to work with recorset, just with an array.

And instead of intCount you can use:

For intItem = 1 To Ubound(anyArray,2)

let me know if you try it, and the result!!!

'paste this into a form with 1 command button and 1 listview

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const LVM_FIRST = &H1000      '// ListView messages
Private Const LVM_SCROLL = (LVM_FIRST + 20)

Private Sub Command1_Click()
Dim HorizPixels, VertPixels As Long
HorizPixels = 0
VertPixels = 30
    SendMessage ListView1.hwnd, LVM_SCROLL, ByVal HorizPixels, ByVal VertPixels
End Sub

Private Sub Form_Load()
Dim i As Integer
For i = 1 To 100
    ListView1.ListItems.Add , , "ListItem" & i
Next i
End Sub

That idea with the array works great. The problem is that
I am changing the columnheaders in the listview control
depending on what option is clicked. For that reason, I
use a Key to access a column and i use the same Key in the
field of the recordset...

ListView.ListItems.SubItems("Key") = Recordset.Fields("Key")

I cant access with the index...yet. I am still working on
a way to do that.
I am going to try to use the scrolling code given also.
Thanks
