SBO - UI - STOPING FORM FROM CLOSING

Hi all,

I'm trying to prevent a form from closing after i pressed the 'OK' button and do some checkings at the it_ITEM_PRESSED item event type. How can i stop it? Is there a way, an error message doesn't work, like it would in R/3. Am i doing it on the wrong event, should i use teh form unload event with some properties, i've tried to do it there, but theres the form.close = False statement doesn't work like in regular VB. Does anyone as a clue? Thanks in advance.
