Hi,
I have the below code which runs after choosing an item from the
listbox (choose the first one). Goes to the below item after 5 seconds
and then goes to another after 5 sec again... So here is my question:
I have a func which I named as process() I want to run this func only
once when each item is selected in the listbox? So how can I do
that???
Thank you,
Cem Louis
