    <p>I've got some classes exported to Luabind in a DLL, and everything is working fine for those 2 classes (LuaScriptManager, EventManager). I can call their functions from Lua and all is well, but now I'm trying to setup some new class in my client executable which links with the DLL and so far no luck at all.</p> <p>Here's the error message I get for every function that I call: "No matching overload found, candidates: void loadResource(ResourceManager&amp;, std::string const&amp;)"</p> <p>The class binding is from <a href="http://www.nuclex.org/articles/5-cxx/1-quick-introduction-to-luabind" rel="nofollow">http://www.nuclex.org/articles/5-cxx/1-quick-introduction-to-luabind</a>:</p> <pre><code>struct Manager { Manager() : m_ResourceCount(0) {} void loadResource(const std::string &amp;sFilename) { ++m_ResourceCount; } size_t getResourceCount() const { return m_ResourceCount; } size_t m_ResourceCount; }; static Manager MyResourceManager; void Bind(lua_State* l) { // Export our class with LuaBind luabind::module(l) [ luabind::class_&lt;Manager&gt;("ResourceManager") .def("loadResource", &amp;Manager::loadResource) .property("ResourceCount", &amp;Manager::getResourceCount) ]; luabind::globals(l)["MyResourceManager"] = &amp;MyResourceManager; } </code></pre> <p>And here's the corresponding lua test code:</p> <pre><code>-- The following call will fail with the above error MyResourceManager:loadResource("abc.res") --MyResourceManager:loadResource("xyz.res") -- If the function is commented out, this will work (accessing the property) ResourceCount = MyResourceManager.ResourceCount -- Calling my other classes' functions work fine LuaScriptManager.GetInstance():WriteLine(ResourceCount) </code></pre> <p>What could be the cause of this strange behavior ?</p>

    1. COOk I've narrowed it down to: if lua state opened in DLL = no working, if lua state opened in client exe = working. But of course I'd like to have the same state in both so I can share objects between them....

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.
