    <p>I am a newbie to C++. I want to use, lacewing-project.org in my C++ project. I read the documentation on how to build it and successfully did it using both <code>DLL - Release</code> and <code>Static Library - Release</code> configurations.</p> <p>Now I don't know how to use this in my project and how to setup and configure my project? I was following <a href="http://www.codeproject.com/Articles/87554/Embedding-a-Webserver-in-your-Win32-C-Application" rel="nofollow">this tutorial</a>, but was stuck in the middle because of missing options in the latest Visual Studio. I use Visual C++ Expression Ed., 2012 on Windows 8</p> <p>I googled and did the following:</p> <ul> <li>Added the lib file and the lacewing.h file in my project.</li> <li>Under Visual C++ Project Properties, in the Linker folder -> Input I added the lib file as Additional Dependencies.</li> </ul> <p>I placed the dll in Windows\System32 folder. Will I need to do anything with the dll other than placing it in win32 folder?</p> <p>My code is from the <a href="https://github.com/udp/lacewing/blob/master/examples/hello_world/hello_world.cc" rel="nofollow">hello world example</a> given in the documentation.</p> <p>When I try to compile I get:</p> <pre><code>1&gt;------ Build started: Project: test, Configuration: Debug Win32 ------ 1&gt; Source.cpp 1&gt;Source.obj : error LNK2019: unresolved external symbol __imp__lw_version referenced in function "void __cdecl on_get(struct lacewing::_webserver *,struct lacewing::_webserver_request *)" (?on_get@@YAXPAU_webserver@lacewing@@PAU_webserver_request@2@@Z) 1&gt;Source.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl lacewing::pump_delete(struct lacewing::_pump *)" (__imp_?pump_delete@lacewing@@YAXPAU_pump@1@@Z) referenced in function _main 1&gt;Source.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: struct lacewing::_error * __thiscall lacewing::_eventpump::start_eventloop(void)" (__imp_?start_eventloop@_eventpump@lacewing@@QAEPAU_error@2@XZ) referenced in function _main 1&gt;Source.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) struct lacewing::_eventpump * __cdecl lacewing::eventpump_new(void)" (__imp_?eventpump_new@lacewing@@YAPAU_eventpump@1@XZ) referenced in function _main 1&gt;Source.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __cdecl lacewing::_stream::writef(char const *,...)"

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
