listbox hscrollbar
Hi, I add strings in listbox by
SendMessage $1 ${LB_ADDSTRING} 1 "STR:$R0"
ListBox has HSCROLL flag. But for enable horizontal scrollbar needed to send message
System::Call user32::SendMessage(i$1,i${LB_SETHORIZONTALEXTENT},i$5,t.r4)
The problem is that i dont know how to get item width by LB_GETITEMRECT message.
