    <p>I am working with an ASP site which requires a "reminder" email to be sent out every x, y and z minutes. I have attempted to start a timer upon an event (like a button click or page load) but this proved to be unreliable as the timers would be disposed of when the server performed an automatic backup or when the aspx.cs file was updated.</p> <p>My new idea is to have a timer constantly running (a check is performed on a page load which ensures its running) and, when it elapses, it checks to see if either x, y or z minutes have elapsed. So if y elapses, it needs to send out a "reminder" email and then restart y's timer.</p> <pre><code>void ParentTimer_Elapsed(object sender, ElapsedEventArgs e) { foreach(Timer childTimer in ChildTimerList) { if(childTimer.Enabled == false) // And therefore has elapsed { sendReminderEmail(childTimer); childTimer = checkAndSetCorrectInterval(childTimer); childTimer.AutoReset = false; childTimer.Enabled = true; } } } </code></pre> <p>The list ChildTimerList would obviously contain x, y and z.</p> <p>Can anybody forsee me running into any problems with this, or are there any better ways to approach it? My perfect solution would be a timer running costantly which doesn't need to be started upon an event but I don't think this is possible with ASP.</p> <p>Furthermore, where should I initialise my parent timer and childlist variables? In a class within the App_Code folder or, statically, in a code-behind aspx.cs page?</p> <p>Thanks in advance.</p> <p>EDIT:</p> <p>Yes, I do mean ASP.NET... :)</p>

    2. CO@giddy ASP with C# can't be classic ASP so the only meaning is ASP.NET :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
