function ticker_start(div) {
    TICKER_CONTENT = document.getElementById(div).innerHTML;
 
    TICKER_RIGHTTOLEFT = false;
    TICKER_SPEED = 2;
    TICKER_PAUSED = false;
    var tickerSupported = false;
    TICKER_WIDTH = document.getElementById(div).style.width;
 
    // Firefox
    if (navigator.userAgent.indexOf("Firefox") != -1 || navigator.userAgent.indexOf("Safari") != -1) {
        document.getElementById(div).innerHTML = "<TABLE  cellspacing='0' cellpadding='0' width='100%'><TR><TD nowrap='nowrap'><SPAN ID='TICKER_BODY' width='100%'>&nbsp;</SPAN></TD></TR></TABLE>";
        tickerSupported = true;
    }
    if (!tickerSupported) document.getElementById(div).outerHTML = ""; else {
        document.getElementById(div).scrollLeft = TICKER_RIGHTTOLEFT ? document.getElementById(div).scrollWidth - document.getElementById(div).offsetWidth : 0;
        document.getElementById("TICKER_BODY").innerHTML = TICKER_CONTENT;
        document.getElementById(div).style.display = "block";
        TICKER_tick(div);
    }
}
 
function TICKER_tick(div) {
    if (!TICKER_PAUSED) document.getElementById(div).scrollLeft += TICKER_SPEED * (TICKER_RIGHTTOLEFT ? -1 : 1);
    if (TICKER_RIGHTTOLEFT && document.getElementById(div).scrollLeft <= 0) document.getElementById(div).scrollLeft = document.getElementById(div).scrollWidth - document.getElementById(div).offsetWidth;
    if (!TICKER_RIGHTTOLEFT && document.getElementById(div).scrollLeft >= document.getElementById(div).scrollWidth - document.getElementById(div).offsetWidth) document.getElementById(div).scrollLeft = 0;
    setTimeout("TICKER_tick('"+div+"')", 30);
}

Ce code servant à afficher différents bandeau contenant des informations provenant d'une base Oracle (exemple: http://www.fotosearch.com/FSE441/x13856029/)

Mais je ne sais pas comment appeler une seule et unique fois ma fonction ticker_start(). Cad remplacer le "TICKERMEDIUM" appelé dans la page .aspx par une variable ou autre, permettant de différencier les div...

Pourriez vous m'aider s'il vous plait?

Cordialement, :D

Ces identifiants lá sont à mettre dans ta chaine de connexion dans ton web.config. Sinon tu vas t'amuser a les écrire dans chaque page et quand il faudra les changer...

            } while (dr.NextResult());
 
            dr.Close();
            conn.Close();
        }
        catch (Exception ex) // intercepte toutes les erreurs
        {
            throw ex;
        }

le catch toutes les exceptions est fortement déconseillé. Si tu veux oublier certaines exceptions alors dis lui lesquelles, mais en catchant toutes les exceptions ton code devient in-maintenable par la suite.

Code:

1

        finally
        {
            conn.Dispose();
        }
    }
}

Par ailleurs , je te conseillerais de jeter un coup d'oeil sur le databinding cela devrait t'aider beaucoup. En voila un petit exemple avec ton code :

Merci beaucoup.

Etant Junior j'approfondis ma connaissance sur ASP.NET de jours en jours. :ccool:
