Drag & Drop Multiple List Entries

[Tupalov]

When a listbox's Multiselect property is set to Extended how do you drag multiple items? If you start moving with the mouse button down, you just select more entries.

Try this example I put together using 2 Listboxes.. (Make sure the DragMode is Manual)..

Private Sub Form_Load()
    Dim iIndex As Integer
    For iIndex = 1 To 10
        List1.AddItem "Item " & iIndex
    Next
End Sub

Private Sub List1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton Then List1.Drag vbBeginDrag
End Sub

Private Sub List1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    List1.Drag vbEndDrag
End Sub

Private Sub List2_DragDrop(Source As Control, X As Single, Y As Single)
    Dim iIndex As Integer
    If TypeOf Source Is ListBox Then
        List2.Clear
        For iIndex = 0 To Source.ListCount - 1
            If Source.Selected(iIndex) Then List2.AddItem Source.List(iIndex)
        Next
    End If
End Sub

I was trying to duplicate the functionality of explorer, where you could select a bunch of items from a list, let go of the mouse, then mousedown on one of the selected items and they would all be dragged.

Thanks.
