Query form when opening the application (update state)

Question

How do I set a form to auto query when opening it?
I read some things about, but did not find a good answer. I made a button which updates selected values in two LOV's. For that button to appear, i need to press the Query button. Else it is not visible.
Any id how I can get the form to open in a state, that the update button becomes visible?
THANKS!

I was able to do this with Javascript. In your first lOV, add the following code in the OnChange event:
javascript:for (var i=0; i < document.forms[0].elements.length; i++)
if (document.forms[0].elements.name.substring(document.forms[0].elements[i].name.indexOf('DEFAULT.')+8,document.forms[0].elements[i].name.lastIndexOf('.01')) == "QUERY_TOP")
do_event(this.form, document.forms[0].elements[i].name, 1, 'ON_CLICK', '');
