最近項目需要，需要把多個datawindow的數據合併成一個excel導出。本地項目沒有其他代碼借鑑，自己接觸PB頂多3個月時間，而網上關於PB的消息少之又少。前些日子在powerbuilder論壇發個帖子求組，幸運得到powerbuilder版主和一位熱心網友提示，通過自己不斷地coding and debug， 我想要的效果終於得到了，:-)
現在我把源碼貢獻出來，大家一起學習，歡迎和我交流。
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,'.')
