    <p>The snippet is very low quality, it is littered with uncompilable code. No repro once I fixed all the mistakes.</p> <pre class="lang-c prettyprint-override"><code>#include "stdafx.h" #include &lt;iostream&gt; using namespace System; //C++ -native classes class NativeFoo { public: NativeFoo(): tested(true){} virtual void execute() { std::cout &lt;&lt; "Native Foo" &lt;&lt; std::endl; } protected: bool tested; }; class NativeBarA :NativeFoo { public: NativeBarA(): NativeFoo(){} void execute() { std::cout &lt;&lt; "Native Bar A" &lt;&lt; std::endl; } }; class NativeBarB : public NativeFoo { public: NativeBarB() :NativeFoo(){} void execute() { std::cout &lt;&lt; "Native Bar B" &lt;&lt; std::endl; } }; //CLI interface public interface class IExecutable { public: void Execute(); }; //C++-CLI classes public ref class ManagedFoo: public IExecutable { private: NativeFoo* impl; public: ManagedFoo(): impl(NULL) { impl = new NativeFoo(); } virtual void Execute() { impl-&gt;execute(); } }; public ref class ManagedBarA: public ManagedFoo { private: NativeBarA* impl; public: ManagedBarA(): ManagedFoo(), impl(NULL) { impl = new NativeBarA(); } virtual void __clrcall Execute() override { impl-&gt;execute(); } }; public ref class ManagedBarB: public ManagedFoo { private: NativeBarB* impl; public: ManagedBarB(): ManagedFoo(), impl(NULL) { impl = new NativeBarB(); } virtual void __clrcall Execute() override { impl-&gt;execute(); } }; //Calling code [STAThread] int main(array&lt;System::String ^&gt; ^args) { ManagedFoo^ mfoo = gcnew ManagedFoo(); ManagedBarA^ mbarA = gcnew ManagedBarA(); ManagedBarB^ mbarB = gcnew ManagedBarB(); mfoo-&gt;Execute(); //OK mbarA-&gt;Execute(); //Fine mbarB-&gt;Execute(); //Fine } </code></pre>

    1. COThanks for the correction.... although the code works it doesn't solve my problem because the above snippet is all in one assembly. Try building 3 dll files: the main application running in one, then the other dll used for the managed classes while the last dll should hold the native classes. You would notice a weird behavior that derived native classes lose their inherited members when their overridden method is called.

    2. COHmm, so the code snippet wasn't just filled with errors, it didn't even demonstrate the problem? I can only guess you forgot to use #pragma managed before #including the header files. You have to learn how to ask better questions. Good luck with it.

    3. COc'mon hans... don't get picky about the #pragma managed ... not necessary in all cases... and as concerns my snippet, i wasn't writing for a test code.. it was simply to demonstrate the nature of the problem.... and of course problem definitions get clearer after some tests. Sometimes things are not what they appear to be!

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.
