    Hi,
    I am writing a web chat facility in asp.
    The problem is that my chat screen has to refresh every 10 seconds to check
    for any new messages in the conversation, this causes a 'click' sound.
    How can you refresh a page with out a 'click' sound? I currently use the
    meta refresh method, but there must be a different way, as other html chat
    clients I have seen do not make the 'click' sound and do not appear to use
    the meta refresh method.
    Thanks
    JJ

    Use JavaScript and XML HTTP to make a call back to the server and receive the newest data then just
    append the new data to the bottom of the text in the screen. Why refresh the whole page every time?

    <script language="javascript" >
    //Set how often to update
    var intsecods = 1;
    //Set the url to get data from
    var url = "http://www.mamma.com"

    var x=setInterval("update()",1000 * intsecods)

    function update() {
    var http = new ActiveXObject("Microsoft.XMLHTTP");
    try{
    http.Open("GET",url,false);
    http.send();
    if(http.readyState==4) {
    data1.innerHTML = http.ResponseText
    }
    }
    catch(e){
    if(e instanceof Error) {
    data1.innerHTML = "no connection";
    }
    }
    }
    </script>
