Hello everyone....
is there any syntax to automatically input a value into pops up input box ?

my case is quite like this :
there is one condition that trigger a pop up input box (actually for password), and i need it to be automatically filled and then automatically press OK...
the other condition, will also trigger the same pop up input box, but i want it to be filled manually....
i need to add some syntax on the first condition, but i have no clue...

can you help me ?
or any other idea for this problem ?
(using default values on input box won`t work)

Thanx =)
