Dear All
I have tried to search my requirement in this form but didnt find my desired query.
i have a column name called Chassis_no varchar2(17),My requirement is that when a user input a character into this column then system show and count total no of input character in the bottom of a column or bottom of form (where all form status displayed) ,the reason for writing this counter is that end user know how many characters he has inputed in the field and how many character remaining out of 17 character.
Regards
Zuhair

Zuhair,
create a timer
start it in the when-new-item-instance of your field
and have the timer update another field with the length
stop the timer in post-text-item of your field
grtz

Zuhair,
you're asking me to write a piece of application
at least have a try yourself
if you are not familiar with timers then search the online help for :
create_timer, find_timer, when-timer-expired, delete_timer and
get_application_property(timer_name)
that should get you started
if you're stuck then post the code you have made so far
and I'll gladly help you out
grtz
Martin

I agree, just play around with interval settings
and that's also why it is important to stop the timer as soon as you no longer need it
do this in the post-text-item trigger and to be sure also in the when-timer-expired
in that trigger put something like :
if :system.cursor_item != <your text item for the chassis nr> then
delete_timer......
