Reply To: invite all budlist in c++

VB6 or VB.NET version do as follow:

Set up our local LV_ITEM to change the selected item = LVIF_STATE

LVITEM.state = LVIS_CHECKED
LVITEM.stateMask = LVIS_STATEIMAGEMASK

The rest you know what to do

where i is totalPals
for i as integer = 0 to totalPals - 1
SendMessage(hwnd, LVM_SETITEMSTATE, i, LVI)
next i

hope this helps.
