Answer 1

下面是个如何使用ClisCtrl控件的例子：
CListCtrl& ListCtrl = GetListCtrl();
LV_COLUMN lvc;
TCHAR *arrTitle[] = {"基本信息", "名称", "代码", "均价", "数目", "...", "...", "...", "..."};
UCHAR nWidth[] = {200, 100, 100, 60, 80, 60, 80, 60, 100};
USHORT nFMT[] = {LVCFMT_LEFT, LVCFMT_CENTER, LVCFMT_CENTER, LVCFMT_RIGHT, LVCFMT_RIGHT, LVCFMT_RIGHT, LVCFMT_RIGHT, LVCFMT_CENTER, LVCFMT_RIGHT};

m_nColumnNum = 0;

lvc.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;

for (int i = 0; i < sizeof(nWidth) / sizeof(UCHAR); i ++)
{
lvc.iSubItem = i;
lvc.pszText = arrTitle[i];
lvc.cx = nWidth[i];
lvc.fmt = nFMT[i];
ListCtrl.InsertColumn(i, &lvc);
m_nColumnNum ++;
}

LV_ITEM lvItem;
int nIndex = 0;
CString strInsertText;
double nTotalProfit = 0;
POSITION curPos;
CStockList *pCurrentStockCode;
TCHAR buff[32];

curPos = m_listExchangedStock.GetHeadPosition();
while (curPos != NULL)
{
....
lvItem.mask = LVIF_TEXT | LVIF_PARAM;
lvItem.iItem = nIndex ++;
lvItem.lParam = NULL;
buff[0] = 0;
lvItem.pszText = buff;
lvItem.iSubItem = 0;
ListCtrl.InsertItem(&lvItem);

lvItem.iSubItem = 1;
lvItem.mask = LVIF_TEXT;
sprintf_s(buff, "%s", pCurrentStockCode->m_cStockName);
ListCtrl.SetItem(&lvItem);

lvItem.iSubItem = 2;
lvItem.mask = LVIF_TEXT;
sprintf_s(buff, "%06d", pCurrentStockCode->m_nStockCode);
ListCtrl.SetItem(&lvItem);

需要把ListCtrl的模式设置为Report:
m_teachers.ModifyStyle( 0, LVS_REPORT );
