I am making a birthday notification in windows service that uses jabber-net library which is a XMPP and System.Threading that must send automatic messages to user every day, but i'm getting an error in logs which says
Unable to cast object of type 'System.Threading.Timer' to type 'jabber.client.JabberClient'. at SparkSalesCrdBirthdays.SparkBirthDayGreeting.j_OnAuthenticate(Object sender)
Here's my code
protected override void OnStart(string[] args)
{
this.WriteToFile("Simple Service started {0}");
JabberClient j = new JabberClient();
// what user/pass to log in as
j.User = "user";
j.Server = "server"; // use gmail.com for GoogleTalk
j.Password = "pass";
//j.Resource = "admin";
// don't do extra stuff, please.
j.AutoPresence = false;
j.AutoRoster = false;
j.AutoReconnect = -1;
j.KeepAlive = 10;
j.AutoLogin = true;
j.AutoStartTLS = false;
j.PlaintextAuth = true;
j.OnError += new bedrock.ExceptionHandler(j_OnError);
// what to do when login completes
j.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate);
// listen for XMPP wire protocol
if (VERBOSE)
{
j.OnReadText += new bedrock.TextHandler(j_OnReadText);
j.OnWriteText += new bedrock.TextHandler(j_OnWriteText);
}
// Set everything in motion
j.Connect();
// wait until sending a message is complete
done.WaitOne();
// logout cleanly
j.Close();
this.ScheduleService();
