Return to SaveAs Dialog Box powerbuilder - dialog

Question

I want to export a datawindow informations to a .txt file. When I click the export button the SaveAs Dialog Box opens. If a .txt document with the same name exists then a MessageBox pop-up questioning if I want to replace the file. If I press NO then SaveAs Dialog Box is closing. How can I prevent SaveAs Dialog Box from closing? I want to return in it and give another name to file.
Here is my code:
li_rc = GetFileSaveName (lcs_title, ls_path_filename, ls_filename, 'txt', 'TXT File (*.txt), *.txt' )
if li_rc > 0 then
if FileExists (ls_path_filename) then
//Existing file has been found
if MessageBox (lcs_title, 'Replace the file '+ ls_path_filename +'?', Question!, YesNo!, 1) = 2 then
//Do not replace the file
//Return to dialog?
else
//Replace the file
dw_1.SaveAs(ls_path_filename, Text!, false)
end if
end if
end if
Thanks!

Try this
boolean lb_need_file = true
do while lb_need_file
li_rc = GetFileSaveName (lcs_title, ls_path_filename, ls_filename, 'txt', 'TXT File (*.txt), *.txt' )
if li_rc > 0 then
if FileExists (ls_path_filename) then
//Existing file has been found
if MessageBox (lcs_title, 'Replace the file '+ ls_path_filename +'?', Question!, YesNo!, 1) = 2 then
//Do not replace the file
//Return to dialog?
else
lb_need_file = false
//Replace the file
dw_1.SaveAs(ls_path_filename, Text!, false)
end if
end if
end if
loop
