1 is true, 0 is false.
You're checking to see if the control does have a value. When you should be checking to see if the control doesn't have a value.

No, you should read the help file on $did().sel (and in fact the entire page on dialogs). Also, when you don't know what something does exactly, USE /echo. Bold cannot stress this enough, /echo is the best way to figure out how stuff works.
$did(name,id,0) -> total number of selected lines
$did(name,id,1) -> index of 1st selected line
$did(name,id,2) -> index of 2nd selected line
Inside an on DIALOG event $did(name,id,N) can be $did(id,N)
/.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com

so then
this : if (! $did(46,0 ).sel) { .did -b protect 49 }
is equal to this?
if ($did(46,1 ).sel) { .did -b protect 49 }
?

"$did(name,id,0) -> total number of selected lines"
then by some logic it should be
if ($did(name,id,0) == 0) { disable coz it has no lines }
no?
anyways that code by hixxy (last) and Slade works.
i just now want to figure out this logic coz it has no
sence to me

Yes.
if ($did(name,id,0) == 0)
is the same as
if (!$did(name,id,0))
which is what hixxy used
/.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com

ehm i just noticed that code actually doesnt work for me  @qwerty so if that is true: if ($did(name,id,0) == 0) then why my button does NOT get disabled when nothing is in list control ?

if ($did(name,id,0)[color:red].sel[/color] == 0) Sometimes, people on here make mistakes in their posts or assume you know what to do and write shorthand versions. It's ok to try and correct things yourself sometimes.

/.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com

Because nothing is selected. One of the items has focus, but it's not selected.

so is this like.. only way it can be ? I would say no it doesnt require that something be selected, I have not tested it though. post your code here and one of will have a solution. However I think you cant check to see if ID 46 has any lines on :dialog:NAME:sclick:46:{ if ($did(!$dname,46).lines) { did -b $dname 49 } else { did -e $dname 49 code to do something with $did(46).seltext }

does this do what you want to do? sample
dialog list {
title "List Box"
size -1 -1 200 100
option dbu
list 100, 20 20 160 60
button "Add", 900, 30 75 60 10
button "Remove", 901, 110 75 60 10
}
;; disable the remove button when starting
on *:dialog:list:init:0:{
did -b list 901
}
;; Add something to the listbox,
;; and if something is added, enable the remove button
on *:dialog:list:sclick:900:{
if ($cb(0)) {
did -a list 100 $cb
did -e list 901
}
}
;; Remove a line from the list
;; if the list is empty, disable the remove button
on *:dialog:list:sclick:901:{
did -d list 100 $did(list,100).sel
if (!$did(list,100).lines) { did -b list 901 }
}
