    <p>Actually i tried to implement some kind of 'statically linked' assemblies, within my solution. So i tried the following:</p> <ul> <li>Adding a reference to my assembly with CopyLocal = false</li> <li>Adding the .dll file itself to my solution with 'Add as link'</li> <li>Adding the .dll file itself to my resources with 'Add Resource' - 'Add Existing File'</li> <li>Adding some type out of my assembly into Form1 as <code>private MyObject temp = new MyObject();</code></li> </ul> <p>After these steps i got the FileNotFoundException as expected. So let's try to load the assembly within the AssemblyResolveEvent with this quick hack</p> <pre><code>AppDomain.CurrentDomain.AssemblyResolve += (sender, e) =&gt; { Assembly MyAssembly = AppDomain.CurrentDomain.Load(Properties.Resources.ExternalAssembly); return MyAssembly; }; </code></pre> <p>So this works! I'm able to load my assembly from a resource file within a AssemblyResolveEvent. But this event only happens, if it couldn't find my assembly anywhere else. But how can i get my assembly be loaded <strong>before</strong> .Net tries to search the different places??</p> <p>Due to the facts from <a href="http://msdn.microsoft.com/en-us/library/aa98tba8.aspx" rel="noreferrer">Checking for Previously Referenced Assemblies</a> i thought it would be possible to load the assembly beforehand into the domain and this would be taken.</p> <p>I tried this within program.cs by using the following Main() method</p> <pre><code>static void Main() { LoadMyAssemblies(); AppDomain.CurrentDomain.AssemblyResolve += (sender, e) =&gt; LoadMyAssemblies(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private static Assembly LoadMyAssemblies() { Assembly result = AppDomain.CurrentDomain.Load(Properties.Resources.MyStaticAssembly); return result; } </code></pre> <p>But it still runs into the ResolveEventHandler. And far more better, if i load the assembly again and take a look into <strong>AppDomain.CurrentDomain.GetAssemblies()</strong> i can see that my assembly is loaded twice!!</p> <p>So any idea why my loaded assembly won't be taken into account when it is loaded before the AssemblyResolve event?? With help of the debugger i also returned a null when the call came from AssemblyResolve, but in this case i got a FileNotFoundException as at the beginning.</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.
