设置LVS_EX_CHECKBOXES风格 
    ListView_SetExtendedListViewStyle(m_List.GetSafeHwnd(), m_List.GetExStyle() | LVS_EX_CHECKBOXES); 
为listctrl添加测试项 
    在OnInitDialog()中添加如下代码： 
     m_List.InsertColumn(0,"Name",LVCFMT_LEFT,150); 
     m_List.InsertColumn(1,"***",LVCFMT_LEFT,200); 
     m_List.InsertItem(0, "ZhangSan"); 
     m_List.InsertItem(1, "LiSi"); 
添加控件通知消息 
    为ListCtrl控件添加LVN_ITEMCHANGED消息。系统生成如下代码： 

void CXXXDlg::OnLvnItemchangedList1(NMHDR *pNMHDR, LRESULT *pResult) 
{ 
LPNMLISTVIEW pNMLV = reinterpret_cast(pNMHDR); 
// TODO: Add your control notification handler code here 
*pResult = 0; 
} 

在LVN_ITEMCHANGED消息处理函数中添加代码如下： 
void CXXXDlg::OnLvnItemchangedList1(NMHDR *pNMHDR, LRESULT *pResult) 
{ 
LPNMLISTVIEW pNMLV = reinterpret_cast(pNMHDR); 
// TODO: Add your control notification handler code here 
/* 
typedef struct tagNMLISTVIEW 
{ 
NMHDR   hdr; 
int     iItem; 
int     iSubItem; 
UINT    uNewState; 
UINT    uOldState; 
UINT    uChanged; 
POINT   ptAction; 
LPARAM  lParam; 
} NMLISTVIEW, *LPNMLISTVIEW; 
*/ 
if((pNMLV->uOldState & INDEXTOSTATEIMAGEMASK(1)) /* old state : unchecked */ 
  && (pNMLV->uNewState & INDEXTOSTATEIMAGEMASK(2)) /* new state : checked */ 
  ) 
{ 
  TRACE("Item %d is checked\n", pNMLV->iItem); 
} 
else if((pNMLV->uOldState & INDEXTOSTATEIMAGEMASK(2)) /* old state : checked */ 
  && (pNMLV->uNewState & INDEXTOSTATEIMAGEMASK(1)) /* new state : unchecked */ 
  ) 
{ 
  TRACE("Item %d is unchecked\n", pNMLV->iItem); 
} 
else 
{ 
  TRACE("Item %d does't change the check-status\n", pNMLV->iItem); 
} 

*pResult = 0; 
}
