    <p>So I have the weirdest of all problems. I just wanted to write a simple c# WinForms tool for personal use when I ran into it. I`ll begin at the very start, the real question will be at the very end.</p> <p>So I made a NotifyIcon Application. This is very simple, I just did:</p> <pre><code>public class MyApp: ApplicationContext { NotifyIcon icon; public MyApp() { // ... } // ... } </code></pre> <p>And start the App just as every other WinForms App:</p> <pre><code>Application.Run(new MyApp()); </code></pre> <p>Now I have added a new MyApp.Data Class Project, which contains a Local Database, and used the edmx helper to generate my EF Models. I have added a static class called Database which should contain all my Queries.</p> <pre><code>public static class DataBase { static MyAppModel db = new MyAppModel(); public static void AddEntry(SomeThing st) { db.SomeThings.AddObject(st); db.SaveChanges(); } public static String[] GetSomeThings(int numberOfEntries) { return db.SomeThings.OrderBy(x =&gt; x.Date).Select(x =&gt; x.Title).Take(numberOfEntries).ToArray(); } } </code></pre> <p>Back in the WinForms NotifyIcon Project, I add MyApp.Data Assembly (and EF Assembly) and when I call <code>DataBase.AddEntry(x)</code> everything works perfectly fine, but when I use <code>Database.GetSomeThings(10)</code> everything breaks.</p> <pre><code>var x = Database.GetSomeThings(10); String[] y = Database.GetSomeThings(10); </code></pre> <p>just silently fails without an error. <code>x</code> and <code>y</code> both don't show up in locals and cannot be watched. Anybody got an idea?</p> <p>edit: i bound directly to comboBox and it magically worked. now i turned the autocompletemode and source on, and i get an error message:</p> <p><em>Für den aktuellen Thread muss der STA-Modus (Single Thread Apartment) festgelegt werden, bevor OLE-Aufrufe ausgeführt werden können. Stellen Sie sicher, dass die Hauptfunktion mit STAThreadAttribute gekennzeichnet ist.</em></p> <p>unfortunately german, but i think i can solve this:</p> <p><a href="http://msdn.microsoft.com/de-de/library/ms182351%28vs.80%29.aspx" rel="nofollow">http://msdn.microsoft.com/de-de/library/ms182351%28vs.80%29.aspx</a></p>

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.
