Question

How can I perform various task (such as email alert/sending news letter) on a configured schedule time on a shared hosting server?

Answer 1

Here’s a Global.ascx.cs file I’ve used to do this sort of thing in the past, using cache expiry to trigger the scheduled task:

public class Global : HttpApplication {     private const string CACHE_ENTRY_KEY = 'ServiceMimicCacheEntry';     private const string CACHE_KEY = 'ServiceMimicCache';      private void Application_Start(object sender, EventArgs e)     {         Application[CACHE_KEY] = HttpContext.Current.Cache;         RegisterCacheEntry();     }      private void RegisterCacheEntry()     {         Cache cache = (Cache)Application[CACHE_KEY];         if (cache[CACHE_ENTRY_KEY] != null) return;         cache.Add(CACHE_ENTRY_KEY, CACHE_ENTRY_KEY, null,                   DateTime.MaxValue, TimeSpan.FromSeconds(120), CacheItemPriority.Normal,                   new CacheItemRemovedCallback(CacheItemRemoved));     }      private void SpawnServiceActions()     {         ThreadStart threadStart = new ThreadStart(DoServiceActions);         Thread thread = new Thread(threadStart);         thread.Start();     }      private void DoServiceActions()     {         // do your scheduled stuff     }      private void CacheItemRemoved(string key, object value, CacheItemRemovedReason reason)     {         SpawnServiceActions();         RegisterCacheEntry();     } } 

At the moment, this fires off your actions every 2 minutes, but this is configurable in the code.
