win32 listBox的行无法选中？

Question

下面是创建listbox代码段，如图，鼠标在红框内都不能点击选中。应该怎样设置listbox属性使鼠标能够选中各行？
HWND hListBox=0;

hListBox = CreateWindow(WC_LISTBOX,

NULL,

WS_CHILD|WS_VSCROLL | WS_TABSTOP | LBS_STANDARD | LBS_OWNERDRAWFIXED | LBS_HASSTRINGS | LBS_MULTICOLUMN | LBS_MULTIPLESEL |
LBS_WANTKEYBOARDINPUT
,
x, 23,
100, rcClient.bottom - rcClient.top - 100,
parentWnd, (HMENU)IDC_ListBox,

(HINSTANCE) GetWindowLong(parentWnd, GWL_HINSTANCE),

NULL);

ShowWindow(hListBox,SW_SHOW);
SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"Clear");
SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"你好");

SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"我好");

SendMessage(hListBox,LB_ADDSTRING ,0,(LPARAM)"他好");
