the methods below used to work but now I get this error:
Error: Sys.Net.WebServiceFailedException: The server method ‘ failed with the following error: System.Net.WebException– Unable to connect to the remote server
how can I fix it?
function CallMe() {
// call server side method
PageMethods.GetData(function (result) {
DcSet("lblUsdRub", result.UsdRub);
DcSet("lblEurRub", result.EurRub);
DcSet("lblMicex", result.Micex);
DcSet("lblUrals", result.Urals);
DcSet("lblUsdEur", result.UsdEur);
DcSet("lblUsdTur", result.UsdTur);
DcSet("lblNasdaq", result.Nasdaq);
DcSet("lblImkb100", result.Imkb100);
});
}
function DcSet(labelName, value) {
document.getElementById(labelName).innerText = value.toFixed(3);
}
(function () {
var status = true;
var fetchService = function () {
if (status) {
CallMe();
status = false;
}
setTimeout(fetchService, 300000); //Every Five Minutes, Update Data 300000
status = true;
}
addLoadEvent(fetchService);
// window.onload = fetchService;
} ());
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function () {
if (oldonload) {
oldonload();
}
func();
}
}

Given that you’re getting a .NET exception, it sounds like the AJAX call is managing to get to your WebMethod without any problems – it sounds like
ExternalManager.GetOnlineData();is failing.I suggest you try calling that in a simple console application which you can debug easily.
