Question

I have two listboxes and am trying to add items from List 1 to List 2, and then be able to remove multiple items from List 2 at once. Note that List 1 stays stagnant (this is how it is supposed to be).

I have the adding items working right:

'Add the selected items to List 2
Dim i As Integer

If lst1.ItemsSelected.Count > 0 Then
    i = 0
    While i < lst1.ListCount
        If lst1.Selected(i) Then
            lst2.AddItem (lst1.ItemData(i) & ";" & lst1.Column(1, i) & ";")
            lst1.Selected(i) = False
        End If
        i = i + 1
    Wend
End If

However, when I try to remove the items from List 2 in a similar way, it only recognises the first selected item as selected and skips over the other items that I have selected. This is the problem. Here is my code:

'Remove the selected items from List 2
Dim i As Integer

If lst2.ItemsSelected.Count > 0 Then
    i = lst2.ListCount - 1
    While i >= 0
       If lst2.Selected(i) Then
           lst2.RemoveItem (i)
           lst2.Selected(i) = False
       End If
        i = i - 1
    Wend
End If

How can I get this working correctly?

Answer 1

As far as I can tell, as soon as you remove one item, all items become unselected, so:

Dim itm As Variant
Dim srem As String
Dim asrem As Variant

    For Each itm In lst2.ItemsSelected
        srem = srem & "," & itm
    Next

    asrem = Split(Mid(srem, 2), ",")
    For i = UBound(asrem) To 0 Step -1
        lst2.RemoveItem lst2.ItemData(asrem(i))
    Next

Note also that this is Access and you are dealing with a value list, so Replace on the text of Row Source will also work.
