    <p>I have a working version of my program, where the main part of my program runs on the same thread as the GUI using a forms.timer.</p> <p>I am trying to upgrade to a better version that uses 2 threads. One of my threads (that processes all of the information) needs to be called repeatedly (on a timer). </p> <p>I am using the following from my main class: </p> <pre><code>Timer tmr = new Timer(new TimerCallback(bot.refresh), null, 0, 1000); </code></pre> <p>Where bot.refresh is the method I want to call every second (1000ms) until I stop it.</p> <pre><code>public void refresh(Object obj) { Debug.WriteLine("Updated: " + DateTime.Now.ToString()); } </code></pre> <p>About 1/3rd of the time the timer will run stop and I will get this output:</p> <pre><code>Updated: 23/11/2013 4:37:24 PM Updated: 23/11/2013 4:37:25 PM Updated: 23/11/2013 4:37:26 PM Updated: 23/11/2013 4:37:27 PM Updated: 23/11/2013 4:37:28 PM Updated: 23/11/2013 4:37:29 PM Updated: 23/11/2013 4:37:30 PM The thread '&lt;No Name&gt;' (0x3f20) has exited with code 0 (0x0). The thread '&lt;No Name&gt;' (0x37a0) has exited with code 0 (0x0). </code></pre> <p>Any suggestions for why this could be happening?</p> <p>Also, <strong>is there a better way I can do this?</strong> I have the feeling that this is an odd way to do it.</p> <p>Thanks for your help.</p> <p>EDIT: </p> <p>Will this go out of scope? This way I can start the timer when I need to rather than when Main is constructed. For it to be referenced does it need to be in the constructor?</p> <pre><code>class Main { Timer tmr; public Main() { } public void start() { tmr = new Timer (new TimerCallback(bot.refresh), null, 0, 1000); } } </code></pre> <p>Thanks.</p>

    2. COThe Thread Timer (tmr) is stopping randomly. (The refresh method I have in this post is the same as what I have in my program). I feel like there is a better way to do this anyway.

    3. COYes, your updated example will not go out of scope because you keep a reference to the variable `tmr` in `Main` outside of the function you created it in. However if you call `Start()` more than once you will loose the reference to the first timer and it will eventually stop by it self. Also note, you really should go take a look at [the .NET naming guidelines](http://msdn.microsoft.com/en-us/library/ms229043%28v=vs.110%29.aspx), your function names really should start with a capital letter.

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.
