Question

Je fais une notification d'anniversaire dans le service Windows qui utilise la librairie jabber-net qui est un XMPP et System.Threading qui doit envoyer des messages automatiques à l'utilisateur tous les jours, mais j'obtiens une erreur dans les journaux qui dit

J'espère que quelqu'un peut me aider. Je suis coincé :( Merci

Le problème est que l » événement JabberClient est traité dans j_OnAuthenticate et l'événement de la minuterie est traitée avec elle.

Schedular = new Timer(new TimerCallback(j_OnAuthenticate)); 
... 
JabberClient j = new JabberClient(); 
j.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate); 

Et j_OnAuthenticate la première chose que vous faites est jeter les sender à JabberClient

private void j_OnAuthenticate(object sender) 
{ 

    try 
    { 
     JabberClient j = (JabberClient)sender; 
     ... 
    } 
    catch (Exception ex) 
    { 
     WriteToFile("Simple Service Error on: {0} " + ex.Message + ex.StackTrace); 

     //Stop the Windows Service. 
     using (System.ServiceProcess.ServiceController serviceController = new System.ServiceProcess.ServiceController("SparkBirthDayGreeting")) 
     { 
      serviceController.Stop(); 
     } 
    } 

les poignées de bloc catch et enregistre l'exception.

Vous devrez changer le code pour faire des choses différentes en fonction de sender par exemple.

if(sender is JabberClient) 
{ 
    //do something 
} 
else if(sender is Timer) 
{ 
    //do something else 
} 

Ou donner la minuterie une fonction de rappel différente
