    <p>I'm using Dotfuscator Pro 4.10 to obfuscate an application built with VS 2012. The .NET code contains managed as well as unmanaged C++/CLI code, thus compiled with /clr.</p> <p>My solution contains a lot of projects. I only allow <em>renaming</em> as obfuscation. Also, as all assemblies/application are in the dotfuscator project, I don't run in library mode. Thus, all interfaces are scrambled.</p> <p>When I obfuscate the assemblies everything works fine but for an assembly (let's call it <em>A.dll</em>). If I disable obfuscation for <em>A.dll</em>, the application works perfectly. If I enable obfuscation for <em>A.dll</em>, I get this:</p> <blockquote> <p><strong>Error</strong>: System.Resources.MissingManifestResourceException</p> <p><strong>Message</strong>: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "<em>ahe.resources</em>" was correctly embedded or linked into assembly "<em>A.dll</em>" at compile time, or that the satellite assemblies required are loadable and fully signed. </p> </blockquote> <p><em>ahe</em> is the scrambled name of a Window Form in <em>A.dll</em> and the exception is thrown here (from <em>ApplyResources()</em>):</p> <pre><code>void InitializeComponent( void ) { this-&gt;components = (gcnew System::ComponentModel::Container()); System::ComponentModel::ComponentResourceManager^resources = (gcnew System::ComponentModel::ComponentResourceManager( A::typeid )); // ... resources-&gt;ApplyResources( this-&gt;mpMyControl, L"mpMyControl" ); // Exception thrown here. // ... } </code></pre> <p>The resources are correctly defined in <em>A.resx</em> (and it works before obfuscating).</p> <p>Notice that this kind of code is used at many places in other assemblies and, when I disallow obfuscation for the problematic assembly <em>A.dll</em>, it works perfectly.</p> <p>So, does somebody have an idea about how to solve the problem? Feel free to ask for more info/details, I don't know what could be important or not.</p> <p>Thanks!</p> <p><strong>Edit 1</strong>: None of the assemblies are signed.</p>

    1. CORenaming obfuscations can break logic that uses reflection. That's probably what's going on here. Perhaps you can apply an attribute to a single class or such, to preserve its name.

    2. COReflection... Well, I'm trying to find the reflection problem in my code.

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.
