将DW数据窗口导出为EXCEL文件的方法（整理）
本文为摘自CSDN论坛帖子收集整理后汇总版本：
---2004年9月3日整理
---原贴见：

鉴于现在很多朋友询问 pb 数据导出到excel 中的问题，导出去后格式和数据
类型不对了，自己写了几个用户对象，
希望能抛砖引玉,加强技术交流,得到大家的支持。
1. nvo_excel 只要是两个接口函数
导出数据存储的数据,可以定义 excel 的标题
public function integer uf_toexcel (datastore ads_data, readonly string as_title)
导出数据窗口的数据,可以定义 excel 的标题
public function integer uf_toexcel (datawindow adw_data, readonly string as_title)
2. 下面是两个用户对象的 sru 文件，自己导入到工程中
$PBExportHeader$uo_ds_base.sru
$PBExportComments$数据存储基类

根据代码，只有 char(8),10,19 才有啊，这是我设计日期，时间等的专用格式

/* 函数名称：uf_dwsaveas_excel
功能 ：将数据窗口数据导出EXCEL文件，并将EXCEL文件默认英文标题替换成中文。
参数 ：datawindow datawin，为用户要导出数据窗口的数据窗口控件名
返回值：integer 1，success；-1，error
流程描述：先用saveasAscii()倒出为excel文件，再替换表头为中文名
设计人：yanhui 2003年11月
修改人：叶文林 2004.4.8
