    <p>The catch clause in your snippet will never catch anything in the shipping version of your app. It <em>does</em> work when you run it with a debugger attached.</p> <p>What you are missing is the way Application.ThreadException behaves. That event fires whenever any unhandled exception is detected. This feature however is <strong>not</strong> enabled when you debug your code. No exception handler is installed to raise the event. This was done so you have a decent way to debug unhandled exceptions. Your code changes that behavior, now there <em>is</em> a try block active, your catch handler gets the exception.</p> <p>To get the code to behave the same way, you'll need to change the unhandled exception handling strategy. Like this:</p> <pre><code> [STAThread] static void Main() { try { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.SetUnhandledExceptionMode(UnhandledExceptionMode.ThrowException); Application.Run(new Form1()); } catch (Exception ex) { // etc.. } } </code></pre> <p>Now your catch clause will always catch the exception. As long as it is raised on the main thread, it won't catch exceptions raised in worker threads. Consider this code instead for unified handling:</p> <pre><code> [STAThread] static void Main() { AppDomain.CurrentDomain.UnhandledException += AllUnhandledExceptions; Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.SetUnhandledExceptionMode(UnhandledExceptionMode.ThrowException); Application.Run(new Form1()); } private static void AllUnhandledExceptions(object sender, UnhandledExceptionEventArgs e) { var ex = (Exception)e.ExceptionObject; // Display or log ex.ToString() //... Environment.Exit(System.Runtime.InteropServices.Marshal.GetHRForException(ex)); } </code></pre>

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.
