控制多个datawindow数据合并成一个excel导出【PB】

最近项目需要，需要把多个datawindow的数据合并成一个excel导出。本地项目没有其他代码借鉴，自己接触PB顶多3个月时间，而网上关于PB的消息少之又少。前些日子在powerbuilder论坛发个帖子求组，幸运得到powerbuilder版主和一位热心网友提示，通过自己不断地coding and debug， 我想要的效果终于得到了，:-)

现在我把源码贡献出来，大家一起学习，欢迎和我交流。

string ls_path, ls_file
double ll_len_path, ll_len_file
int li_rc
Long j

if dw_preview.RowCount() > 0 then

li_rc = GetFileSaveName ( "Select File", ls_path, ls_file, "XLS", "Excel Files (*.XLS), *.XLS,All Files (*.*)" , "", 32770)
//get the filename from user
ll_len_file=LastPos(ls_file,'.')

if li_rc = 1 then
