Text Tutorial</h2>
<ol type="1">
<li>Make sure you have Visual Studio 2019 or 2022. Community, Professional or Enterprise work fine. These instructions are not for Visual Studio Code. You can <a href="https://visualstudio.microsoft.com/downloads/">download the correct version here</a>. Note that older versions of Visual Studio will not work as they do not support enough of the C++17 standard.</li>
<li>Clone the <a href="https://github.com/brainboxdotcc/windows-bot-template/">template project</a>. Be sure to clone the entire project and not just copy and paste the <code>.cpp</code> file.</li>
<li>Double click on the <code>MyBot.sln</code> file in the folder you just cloned: <div class="image">
<img src="vsproj_1.png" alt=""/>
</div>
</li>
<li>Add your bot token (see <a class="el" href="creating-a-bot-application.html">Creating a Bot Token</a>) and guild ID to the example program: <div class="image">
<img src="vsproj_2.png" alt=""/>
</div>
</li>
<li>Click "Local Windows debugger" to compile and run your bot! <div class="image">
<img src="vsproj_3.png" alt=""/>
</div>
</li>
<li>Observe the build output, so long as the build output ends with "1 succeeded" then the process has worked. You may now run your bot! <div class="image">

Troubleshooting</h2>
<ul>
<li>If you get an error that looks like this: <div class="fragment"><div class="line"> 1>MyBot.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class dpp::async<struct dpp::confirmation_callback_t></div>
<div class="line">__cdecl dpp::interaction_create_t::co_reply(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)const</div>
<div class="line">" (__imp_?co_reply@interaction_create_t@dpp@@QEBA?AV?$async@Uconfirmation_callback_t@dpp@@@2@AEBV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z)</div>
<div class="line">referenced in function "public: class dpp::task<void> __cdecl `int __cdecl main(void)'::`2'::<lambda_2>$_ResumeCoro$1::operator()(struct dpp::slashcommand_t const &)const "</div>
<div class="line">(??R<lambda_2>$_ResumeCoro$1@?1??main@@YAHXZ@QEBA?AV?$task@X@dpp@@AEBUslashcommand_t@3@@Z)</div>
<div class="line">1>...\windows-bot-template-main\x64\Debug\MyBot.exe : fatal error LNK1120: 1 unresolved externals</div>
<div class="line">1>Done building project "MyBot.vcxproj" -- FAILED.</div>
</div><!-- fragment --> Make sure your don't have another version of the library installed through vcpkg. The template uses a slightly different version of D++ that has coroutines, while the vcpkg version does not, and the latter overwrites it! Uninstalling the library through vcpkg should fix this issue.</li>
<li>If you get an error that a DLL is missing (e.g. <code>dpp.dll</code> or <code>opus.dll</code>) when starting your bot, then simply copy all DLLs from the <b>bin</b> directory of where you cloned the D++ repository to, into the same directory where your bot's executable is. You only need to do this once. There should be several of these DLL files: <code>dpp.dll</code>, <code>zlib.dll</code>, <code>openssl.dll</code> and <code>libcrypto.dll</code> (or similarly named SSL related files), and <code>opus.dll</code>. Note the template project does this for you, so you should never encounter this issue.</li>
<li>If you get an error that says "Debug/Release mismatch", <b>you are using the wrong configuration of the D++ dll</b>. Your bot's executable and the dpp.dll file should both be built in the same configuration (Release or Debug), you get this error if they are different. <b>This also means you altered the template in a significant way,</b> we recommend you undo your modifications or reinstall the template.</li>
