MFC将ListCtrl列表导出到Excel-采用文件流写Excel兼容Html格式（不需要Excel环境）

如标题所言，将ListCtrl的内容导出到Excel文件。不需要Excel环境支持！

	TCHAR szFilter[] = _T("Excel文件(*.xls)|*.xls|所有文件(*.*)|*.*||");   
	CFileDialog file(FALSE, _T(".xls"), _T("TransForm"), OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter, this);  

	CString strSavePath = _T(""); //!<保存路径  
	if(IDOK == file.DoModal())  
	{  
		strSavePath = file.GetPathName();  
	}

	//!<导出的xls文件路径
	if (strSavePath != _T(""))
	{

		std::string szHander = "";
		szHander = "<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>";
