my question is, I have to send mail at specific time daily, is there any way to do this in asp.net ? give me appropriate suggestions. Note : i don't want to run windows application or windows scheduler.
code which i used in global.asax
private static CacheItemRemovedCallback OnCacheRemove = null;
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
AddTask("Remoder", 5);
}
void Application_End(object sender, EventArgs e)
{
// Code that runs on application shutdown
}
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
}
void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}
void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the sessionstate mode
开发者_开发知识库 // is set to InProc in the Web.config file. If session mode is set to StateServer
// or SQLServer, the event is not raised.
}
private void AddTask(string name, int seconds)
{
OnCacheRemove = new CacheItemRemovedCallback(CacheItemRemoved);
HttpRuntime.Cache.Insert(name, seconds, null,
DateTime.Now.AddSeconds(seconds), Cache.NoSlidingExpiration,
CacheItemPriority.NotRemovable, OnCacheRemove);
}
public void CacheItemRemoved(string k, object v, CacheItemRemovedReason r)
{
// do stuff here if it matches our taskname, like WebRequest
// re-add our task so it recurs
AddTask(k, Convert.ToInt32(v));
}
public void Remoder()
{
HttpContext.Current.Response.Write("Hello Start");
}
Have a look at http://quartznet.sourceforge.net/
I think this technique from Jeff Himself is what you need: https://blog.stackoverflow.com/2008/07/easy-background-tasks-in-aspnet/
I tried the hack ... turning your application global.asax into a virtual scheduler. It was my choice, because my server admin department simply refuses (because they don't understand) to do it with windows, or a database job.
If I had my druthers though, I'd use a database "job", since sql-server can send mail directly. Not sure what db you're using, but if you have the necessary access, I'd recommend looking for a solution like that, instead of trying to fool your asp.net app.
