	Hello, You are right, thanks, we will check what can be done. If you populate data in some loop you can send WM_SETREDRAW message to stop redrawing on each step. It can increase perfomance: 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 Const WM_SETREDRAW = &HB SendMessage ListView1.hwnd, WM_SETREDRAW, 0, 0 For i = 1 To 10000 ListView1.ListItems.Add , , Item & i Next SendMessage ListView1.hwnd, WM_SETREDRAW, 1, 0
