asp.net singleton class Syed M Hussain10-Apr-12 0:27 Syed M Hussain 10-Apr-12 0:27  Hi guys Hope someone can help with a question, Im not an asp.net developer so please bare with me. I created a very simple Singleton class, that is, its not thread safe. Now I would have though that the singleton class instance would only exist for a single page request. What I am finding is that my test singleton instance persists over several http requests. I wanted to develop a very small cms with a single db instance that exists only for each page request. So really my question is how does IIS keep the singleton instance alive for several page requests.

Re: Chat Room With Private Message JHizzle11-Apr-12 3:22 JHizzle 11-Apr-12 3:22  Have you considered an overall design/approach at all? There's probably multiple ways to employ this, I can think of at least one pretty basic structure off the top of my head but there will be an unwillingness to help "do your job" unless you provide some input to indicate that you've done at least some of the basic work. The limit of sending large number of emails Elham M9-Apr-12 22:51 Elham M 9-Apr-12 22:51  Hi, We have a website that sends multiple emails on many events, but we have heard that if the number of sent emails becomes more than a limit in one hour, the receiving mail server (such as Yahoo! and Gmail) detects the sender as a spam sender and moves all of those mails to receivers’ spam instead of inbox. Our question is that what is that limit and How to ignore or eliminate this limit? Thanks. Be silent and more think Re: The limit of sending large number of emails Abhinav S9-Apr-12 23:16 Abhinav S 9-Apr-12 23:16  This limit is set on external servers and cannot be controlled by you. Re: The limit of sending large number of emails JHizzle11-Apr-12 3:23 JHizzle 11-Apr-12 3:23  You'll need to go to the faqs or contact us section of each provider that you are concerned about and ask them directly as they will likely have varying levels, once you've got a decent cross section you can determine what a reasonable limit to set is. how to detect upload dialog closing? Ali Al Omairi(Abu AlHassan)9-Apr-12 20:48 Ali Al Omairi(Abu AlHassan) 9-Apr-12 20:48  guys; As we know file upload uses a file dialog to let the user select the file to be uploaded. In most browsers the js code execution stops until the dialog is closed, but not in Safary and Opera. I am wondering if there is a way to detect the dialog closing.
