problem:LISTBOX send LB_SETSEL message ,set the first line initially

[aneird]

build listbox window：
hwndList = CreateWindow("LISTBOX",
"",
WS_CHILD| WS_VISIBLE|LBS_NOINTEGRALHEIGHT|WS_VSCROLL|LBS_OWNERDRAWFIXED|LBS_NOTIFY|LBS_MULTIPLESEL ,
0, 0, 0, 0, hWnd, NULL, hHistoryInst, NULL);

set the first line：
SendMessage(hwndList , LB_SETSEL , (WPARAM)TRUE , (LPARAM)0);

but the result has problem!
the be set line not show,as the result that click the downarrow VSCROLL one times !

May be send message LB_SETSEL(set the first line) before building the list ?
