Hi and welcome to Bytes.

This is a common question, and the simple answer is that you can not. ASP runs on the server BEFORE it is sent to the user. No ASP code can execute AFTER the user receives it. We use javascript, ajax, or CSS or some such to execute code after the browser receives the page.

Can ASP experts get around that difficulty? Yes. One of the simplest ways to do it is to have a frame on the page, when the button is clicked, code is sent to refresh that frame. You can send the information for the function you want to call in the code to refresh the page. Does this make sense?

If you need further help, please explain what you are trying to do.

Concurred. I've used that method a few times myself, mostly on admin panels.

I am becoming a fan of the AJAX method tho' especially when using jQuery :)

Yeah, I need to learn Ajax, unfortunately it's not yet at the top of my list.

Here's a simple call to page to fill a div in jQuery:

$.ajax({

        type: "GET",

        url: "viewproducts.asp",

        data: "product=<%=rs("productid")%>",

        success: function(html){

        $("#ProductDetail").html(html);

        }

    });

Simple, but extremely effective.

Gaz.
