    <p>Basically i have a problem with this timer program I am trying to put together. On starting the program it will utilise a steady 25% CPU which i dont mind, but every time the timer fires it adds another 25% on to the CPU so on the 4th pass im completely maxed out.</p> <p>I take it I'm not disposing of the timer correctly after it has fired but im new to c# and not really sure how to go about this.</p> <p>the cope of my program is basically:</p> <ul> <li>Execute some procedures - once completed start timer</li> <li>Wait until timer elapses then start procedures again, disabling the timer until completed</li> </ul> <p>any help would be greatly appreciated :)</p> <pre><code>private static void OnTimedEvent(object source, ElapsedEventArgs e) { IpCheck(); } private static void EnableTimer() { System.Timers.Timer aTimer = new System.Timers.Timer(); // Set the Interval to x seconds. aTimer.Interval = 10000; aTimer.Enabled=true; aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent); aTimer.Enabled = false; aTimer.Dispose(); } </code></pre> <p>ok revised version below - simplified and ruled out the ip check so all it does now is show a message box - this will not even execute anymore :(</p> <pre><code>public class Timer1 { System.Timers.Timer aTimer = new System.Timers.Timer(); public static void Main() { Timer1 tTimer = new Timer1(); tTimer.EnableTimer(); } private void OnTimedEvent(object source, ElapsedEventArgs e) { aTimer.Enabled = false; MessageBoxPrint(); aTimer.Enabled = true; } private void EnableTimer() { // Set the Interval to x seconds. aTimer.Interval = 10000; aTimer.Enabled=true; aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent); } public static void MessageBoxPrint() { MessageBox.Show("Testing"); } } </code></pre>

    1. COYou're problem is not shown in the code posted. You almost certainly have an infinite loop inside `IpCheck()`. Let me guess, you're on a 4-core machine, which is why you're seeing each pass add 25% to the CPU - each pass is consuming an entire core at 100%. However, this suggests you are starting new threads, which you haven't shown in this code either.

    2. COsimplified things as shown above to only output a message box and still hvaing the same issue with CPU :(

    3. COtTimer is a Timer1, which creates another tTimer, which creates another tTimer etc....

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.
