Hi guys

  I was trying to retrieve a composite datawindow, the datawindow was combined by about 15 datawindows which has a retrieval agrument which was a string  ,I tried the code below it just DID NOT wrok as my expected ,it always poped up the the specify retrieval agrument dialog box even the result was OK,any idea how to deal with this issue? thank you so much

DataWindowChild ldwc_child
string ls_dw

dw_print.reset()

for ll_row=1 to 15
ls_dw="dw_"+string(ll_row)
dw_print.GetChild (ls_dw, ldwc_child)
ldwc_child.settransobject(sqlca)
ldwc_child.retrieve(ls_listno)

if ll_row=1 then
ldwc_child.setitem(ldwc_child.rowcount(),"hosp_lv","11")

end if
next

dw_print.visible=true
dw_print.print()
