BOOL CMainDialog::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
	// TODO: 在此添加专用代码和/或调用基类
	//屏蔽两个消息通知码，使得禁止拖动List表头   
	NMHEADER* pNMHeader = (NMHEADER*)lParam;
	if (((pNMHeader->hdr.code == HDN_BEGINTRACKW) |
		(pNMHeader->hdr.code == HDN_DIVIDERDBLCLICKW)))

	// TODO: 在此添加控件通知处理程序代码
	NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
	if (pNMListView->iItem != -1)
	{
		CString strtemp;
		strtemp.Format(_T("单击的是第%d行第%d列"),
