Hi All,

"3" ..... so on . I need to print number with respect to selected

"50" , I need to print "50" as output.
Thanks in Advance.

When you build the form, create the callback string so that it has the number as
part of the callback (e.g. using sprintf).

This is a wild guess because you gave very little info to go on - you didn't
show any code, or give any clue how you're creating the form.

Hi Andrew,
Thanks for u reply, I didnot get u. I have a form which
consists of a listbox field on left with few choices and callbacks,
and scrollbar filed with 100 buttons on right. My code is like this

/* I have created listbox field with function
trnames = hiCreateListBoxField(?name
'trnames.........) */

/* for creating scrollbar region with 100 buttons */
trnumm = nil
for(i 1 100
trnumm = constar(artMakeString(i) trnumm)
)
trnumm = reverse(trnumm)
scroll_nums = hiCreateScrollRegion(?name 'scroll_nums)

foreach(i numm
trstri = stringToSymbol(strcat("trstr" i))
rowbutt = evalstring(i)/10
colbutt = modulo(evalstring(i) 10)
hiAddField(scroll_nums list(
hiCreateFormButton(?
name stringToSymbol(get_pname(trstri))
?buttonText i
?callback
"println(i)")
list(colbutt*30
rowbutt*30) list(30 30) 10
)
)
)


hiCreateAppForm(?name 'trAppForm
?fields list(list(trnames 0:0 200:500)
list(scroll_nums 200:0 300:500))
?initialsize list(500 500)
?fieldfocus 'allTypein
)

hiDisplayForm(trAppform)


I am getting the form with specified listbox on left and buttons in
scroll region on right. My problem is when I click the button in
scrollbar region , the output is the value of current "i" in CIW
window . But I want the buttonText which i have pressed . The form
should not close after a click on button, still it should wait for new
button press until the form is closed by ok or cancel button.
I need your help in these.

Thanks.

Hmm. First of all, saying things like "Thanks for 'u' reply, I didnot get 'u'"
immediately gets my back up. There's no tax on characters, so please write
English words (even if English is not your first language, using such
abbreviations should be the preserve of SMS text messaging, not somewhere where
you expect somebody to be able to easily read your questions).

Secondly your code does not run as is, for several reasons:

1. You have a line foreach(i numm ... but no variable numm (it should be trnumm).
2. The formatting is awful, making it hard to read. Line wrapping after meant
that ?name got split into ? and name on separate lines, which broke the code.
3. The hiCreateAppForm refers to a variable trnames, not defined anywhere
4. The arguments to hiCreateAppForm ?initialsize and ?fieldfocus should be
?initialSize and ?fieldFocus

Luckily I had the patience to ignore your 'u' and to fix the mistakes in your
code (best to test it before posting, so that those of us trying to help out in
our spare time do not spend excessive amounts of that time fixing your mistakes,
which limits the likelihood of you getting an answer).

Change the ?callback argument in hiCreateFormButton to:

?callback sprintf(nil "println(%s)" i)

As I said, build the callback. You cannot just reference a variable i in your
callback as you did, because it will not be in scope at the time the callback is
executed.

Other suggestion - don't use evalstring() to convert a string to an integer. Use
atoi(). evalstring() is less efficient, and if for some reason the string you're
evaluating contains (say) "exit()" you'll realise why you shouldn't use evalstring!

Hi Andrew,
I deeply appologize for my previous mail. I have no skills
especially to post questions and way of expressing things. Please
forgive me for my typo mistakes like initialsize , fieldfocus instead
of initialSize and fieldFocus .
I have posted likely correct way but the appearance in forum is
different. I don't know where I did mistake.
Thanks for your reply once again. The reply is so important for me.
Yes , its "trnumm" not "numm".

?callback sprintf(nil "println(%s)" i)

Hurry! its working . I am very happy. Its fantastic.
