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
