    <p>Well this is possible, but not a small amount of work. It's generally easier to create the appdomain and set configuration from the managed world and then create a small 'thunking' layer in managed code to wrap it all up for unmanaged clients. But since that isn't what you asked for, here is how you could accomplish your goal: </p> <p>First you will need to import the mscorelib:</p> <pre><code>#include &lt;mscoree.h&gt; #import &lt;mscorlib.tlb&gt; raw_interfaces_only no_smart_pointers high_property_prefixes("_get","_put","_putref") </code></pre> <p>Then bind to the runtime:</p> <pre><code>ICorRuntimeHost runtimeHost; hr = CorBindToRuntimeEx( NULL, //Retrieve latest version by default L"wks", //Request a WorkStation build of the CLR STARTUP_LOADER_OPTIMIZATION_SINGLE_DOMAIN | STARTUP_CONCURRENT_GC, CLSID_CorRuntimeHost, IID_ICorRuntimeHost, (void**)&amp;runtimeHost ); </code></pre> <p>Now startup the CLR and create an AppDomainSetup instance.</p> <pre><code>hr = runtimeHost-&gt;Start(); IAppDomainSetup pSetup; hr = runtimeHost-&gt;CreateDomainSetup(&amp;pSetup); </code></pre> <p>Now fill in the setup information as appropriate:</p> <pre><code>hr = pSetup-&gt;put_ApplicationBase(_bstr_t(thisFile)); hr = pSetup-&gt;put_ConfigurationFile(_bstr_t(configFile)); </code></pre> <p>Finally create the domain:</p> <pre><code>hr = __gRuntimeHost-&gt;CreateDomainEx(L"ISAPI.Net", pSetup, NULL, &amp;pDomain); </code></pre> <p>Now you can optionally instantiate an object and call methods:</p> <pre><code>hr = pDomain-&gt;CreateInstanceFrom(_bstr_t(assemblyFile), _bstr_t("Namespace.ClassName"), &amp;pObjectHandle); VARIANT vtUnwrapped; hr = spObjectHandle-&gt;Unwrap(&amp;vtUnwrapped); IDispatch pDisp = vtUnwrapped.pdispVal; DISPID dispid; DISPPARAMS dispparamsNoArgs = {NULL, NULL, 0, 0}; hr = pDisp-&gt;GetIDsOfNames ( IID_NULL, szMemberName, 1, LOCALE_SYSTEM_DEFAULT, &amp;dispid ); hr = pDisp-&gt;Invoke ( dispid, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, &amp;dispparamsNoArgs, NULL, NULL, NULL ); </code></pre> <p>Obviously the code fragments above are incomplete; however, if your adept enough at C++ COM the above should provide you with enough information to work it out. You should note that this is the 'old' (1.x) hosting interfaces which I can attest continue to work through 3.5, I have no idea how/if these work on 4.0. As of <a href="http://msdn.microsoft.com/en-us/library/ms164336%28v=VS.80%29.aspx" rel="nofollow">.Net 2.0 new hosting interfaces</a> were introduced. I've never had need of anything beyond the 1.x versions, so I never bothered to upgrade any hosting code.</p> <p>see also: <a href="http://msdn.microsoft.com/en-us/library/dd380850.aspx" rel="nofollow">Hosting Overview</a></p>

    1. CO@csharptest.net: Thank you, currently trying this now, and also considering the thunking solution. I will definitely let you know which solution I end up with.

    2. COI've done both, I'll tell you now I prefer the thunking layer in managed code; however, both are plausible solutions.

    3. COVery interesting. I'm afraid to say I'm unfamiliar with creating this managed thunking layer. Would it be considered thunking if I make a C++/CLI layer which wraps up the managed configuration (and then calling methods on that C++/CLI layer from unmanaged C++), or am I just wrong about this one?

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.
