Oracle Forms

Hi everybody,

I'm very new to oracle. actually rite now i'm learning oracle. I want to populate the form before the form opens. i dunno how to do that. i did some research and i figured that there is an execute query command to run unrestricted query but i can't find the appropriate tigger that i can invoke which would load the form before the form is dispayed.

I have another question does anybody know if we can reset window size when the form is displayed. If yes then how?

thanks
Julie
