It's possible, but you can't pass a .NET object to a native DLL, which is a native C++ code... The equivalent of an .NET object in native C++ is C++ object... but this is like asking a C# to understand Native or PHP, or.... So, there are several approaches. Don't use C++ managed wrapper. Instead using Marsahling and C# interoperability directly call into native C++, in 1 of 2 ways: <ol> <li>Pass the object fields as a long list of parameters to the C++ and re-construct the object inside native C++. A bit "not nice" approach but very efficient and easy to debug.</li> <li>You can also pass the object as a class pointer to the C++ native directly, you need first to create the right marshaling in C#. See here: <a href="http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshal(v=vs.110).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshal(v=vs.110).aspx</a></li> </ol> Use C++ Interop (which you are doing...). You need to compile with Mixed mode! See this nice example: <a href="http://social.msdn.microsoft.com/Forums/en-US/vclanguage/thread/f2de75c5-50a6-41ac-9ddf-694a8c0ce75b/" rel="nofollow">http://social.msdn.microsoft.com/Forums/en-US/vclanguage/thread/f2de75c5-50a6-41ac-9ddf-694a8c0ce75b/</a> BUT... you need to understand the basics and know how to compile it: <a href="http://msdn.microsoft.com/en-us/library/x0w2664k.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/x0w2664k.aspx</a> Interoperability is a complex issue... and I try to write a short answer, please revert to me for further clarifications....

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.
