pb 嵌套数据窗口怎样导出为XML文件

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

原因：为提高程序的可读性作了少量的修改(如：增加注释、改变排版风格等)*/
