problem with checkbox

Former Member — Fri, 06 Feb 2009 04:42:11 GMT

hi expert,

i create report with check box at begin of write data in tab. after execute, i get report like this


1  (checkbox)  xxxxx x xxx xxxxxxxxxxxxxxxx
2  (checkbox)  xxxxx x xxx xxxxxxxxxxxxxxxx
3  (checkbox)  xxxxx x xxx xxxxxxxxxxxxxxxx
4  (checkbox)  xxxxx x xxx xxxxxxxxxxxxxxxx

when user select check box of desire line and press F8 button system will display only selected line.so i set check box default as 'X'.


Data:
  chk_box          type c value 'X',
  chk_box_val,


write:/1 1tab-xxxxx,
         30 chk_box as checkbox

like this all checkbox in report is checked

so i will update field in 1tab to flag that this line is select. if user execute report and don't unmark, all line should display in second execute.

but it don't, nothing display. where is incorrect in my code? for easy to look, this is a relative part of code in my report.

 
at line-selection.
    perform selectline.
at pf8.
    perform printnewheader.
    perform printselectline.

form selectline.
  data xnum like rmtab-runno.
  read current line field value chk_box into chk_box_val.
  if chk_box_val is initial.
    chk_box_val = 'X'.
  else.
    chk_box_val = space.
  endif.

  modify current line field value chk_box from chk_box_val.
  if chk_box_val = 'X'.
    xnum = 1tab-runno.
    loop at 1tab where runno = xnum.
      1tab-chk = 'X'.
      modify 1tab.
      clear 1tab.
    endloop.
  else.
    xnum = 1tab-runno.
    loop at 1tab where runno = xnum.
      clear 1tab-chk.
      modify 1tab.
      clear 1tab.
    endloop.
  endif.
endform.             " selectline

form print-doc-select.
  loop at 1tab where chk = 'X'.

   write:/ ................
endform.

once i arrange code like this, but it's nothing

 
*at line-selection.
*    perform selectline.
at pf8.
    perform selectline.
    perform printnewheader.
    perform printselectline.

 (later is as same as above quote)

thank you in advance. point for good advise.

Kittisak.

Hi,

First remove the default value 'X'.

Bcoz,it will hold 'X' even if you dont check the chedcdkbox also.

After read ,the else condition is not needed.

Clear checkbox after modifying.

HI,

First you have to describe the number of lines in list.TO do this

declare like this

And I modified your code. and dont mention the default value for check box.U can select dynamically by using the below code.It gives a good user interface. Based on the below code u can modify your code .Please check it out once...

data:

w_lines type i, " number of lines

w_linno type i. " line number

at line-selection.

perform selectline.

at pf8.

perform printnewheader.

perform printselectline.

form selectline.

data xnum like rmtab-runno.

describe list number of lines w_lines.

do w_lines times.

read current line w_lineno value chk_box into chk_box_val.

if chk_box_val is initial.

chk_box_val = 'X'.

else.

chk_box_val = space.

endif.

modify current line w_linno value chk_box from chk_box_val.

if chk_box_val = 'X'.

xnum = 1tab-runno.

loop at 1tab where runno = xnum.

1tab-chk = 'X'.

modify 1tab.

clear 1tab.

endloop.

else.

xnum = 1tab-runno.

loop at 1tab where runno = xnum.

clear 1tab-chk.

modify 1tab.

clear 1tab.

endloop.

endif.

clear chk_box .

add 1 to w_linno.

enddo.

endform. " selectline

form print-doc-select.

loop at 1tab where chk = 'X'.

write:/ ................

endform.

In this code

form selectline.

data xnum like rmtab-runno.

read current line field value chk_box into chk_box_val.

if chk_box_val is initial.

chk_box_val = 'X'.

else.

chk_box_val = space.

endif.

you are changing the chkbox value to space so thats why its not excuting

if the value by default is X then there is no need to check the value of the checkbox

Hope this helps!

Thanks
