You can't do it silently as far as I know.

But as to making it go to the bottom have you tried using a page anchor/bookmark and have it load a URL (e.g. thepage.asp#bottom) targeted to the frame instead of refreshing it?

Refreshing an IFRAME without IE's annoying click sound
Hugo, try this:

function UpdateChat() {
window.frames["ChatIFrame"].document.location.reload();
window.setTimeOut("UpdateChat()", 3000);
}

The secret is the "document.location.reload()" function which will allow it to be refreshed without the annoying IE click sound! Silence is golden. Very Happy

Also, you can make the browser jump to the bottom of your chat IFrame window by doing this. Add a <DIV ID=ScrollHere></DIV> at the bottom of the ChatIFrame html. Then, right after that, add this JavaScript:

<SCRIPT LANGUAGE=JavaScript>
document.getElementById("ScrollHere").scrollTop = 99999;
</SCRIPT>

This will cause the ScrollHere DIV element to be scrolled to the top of the window every time it the ChatIFrame is reloaded by the previous bit of code I gave you. The "99999" refers to the number of pixels to scroll it by. You can add a few more 9's if you want to. You always want that to be longer than the actual height of the ChatIFrame, no matter how long the chat gets.

One more thing: you can fix the flickering by using a hidden IFRAME which will contain your chat updates. Then just use some JavaScript to check for when the hidden IFRAME has new chat content, grab the new content, and dynamically add it into the visible IFRAME html so the user can see it. By using JavaScript to add things dynamically, you won't have the entire visible page being constantly reloaded... the browser will first clear the page (which results in the visible flicker) then wait for the new content to be loaded... during this wait, which can take a second or two, the user is staring at a blank window. But if you put this into a hidden IFRAME, they never see it. Only when the hidden IFRAME is done loading will the visible content be quietly updated so they just see a new line of chat content appear below the existing content.
