When a client click a check box (for example) in his browser, I want a 
script located in web server executed, but the contents(the page) in the 
browser do not change, except that check box checked changes its status. 
Certainly, I do not write something like:

window.location(whatever.asp?item1="x"&item2="y");

If you layout a check box in a form, you need to click a "submit" button, 
which is also what I try to avoid.

Another trick is to load the same page back, but it causes flush.
Can anyone tell a better solution?

Thanks so much.

2 ways I can think of (without going into nitty gritty detail):

1. Put the page in a frameset with a hidden frame (a frame with the height 
or width set to zero). Use javascript to load the ASP script page into the 
hidden frame when the checkbox is clicked.

2. Use javascript to open the ASP script page in a small popup window when 
the checkbox is clicked. This will run the script and also display a 
confimation message, and if you wanted you could put a "Close Window" 
button on there so the user can close the pop-up.

Matt, your way 2 is cleaner and works very well, 
though I have not tried way 1 yet.
Thanks a lot.
