First, add a button to your canvas and write this code:when button pressed Declare   vfilename varchar2(500);   in_file   Client_Text_IO.File_Type;   linebuf   VARCHAR2(1800);    i number := 0; BEGIN     vfilename := client_get_file_name('c:/temp/', File_Filter=>'Comma Dialimeted Files (*.csv)|*.csv|');      in_file := client_Text_IO.Fopen(vfilename, 'r');       GO_BLOCK('DATA');      FIRST_RECORD;     LOOP     Client_Text_IO.Get_Line(in_file, linebuf);      p_output_line(linebuf);     Client_Text_IO.New_Line;      Next_record;      i:=i+1;   END LOOP;     FIRST_RECORD; EXCEPTION   WHEN no_data_found THEN     Client_Text_IO.Put_Line('Closing the file...');     Client_Text_IO.Fclose(in_file); END; --------------------------- Secode , add this procedure to your program unit ------------------------------------------------------------------------------------ -- TAREK FATHY -- MARCH 1
