title: How to know which className to search for with EnumChildWindows()?
body: <p>I am looking for the classNames of the form fields in a parent window.</p>
  <p><a href="https://i.imgur.com/KhswjkE.jpg" rel="nofollow noreferrer">Parent Window</a></p>
  <p>I find the parent window with: <code>handle = FindWindowA(NULL, &quot;Riot Client&quot;);</code></p>
  <p>I enumerate through the parents child windows with: <code>EnumChildWindows(handle, &amp;findChild, (LPARAM)&amp;child);</code></p>
  <p><code>findChild()</code> written as:</p>
  <pre><code>BOOL CALLBACK findChild(HWND child, LPARAM lParam) {
      char className[64];
      ::GetClassNameA(child, className, sizeof(className));
      std::cout &lt;&lt; className;
      std::cout &lt;&lt; &quot;\n&quot;;      
      if (!strcmp(className, &quot;Riot Client&quot;)) {
          *(HWND*)lParam = child;
          return FALSE;
      }
      return TRUE;
  }
  </code></pre>
  <p>I have tried to find the child window with <code>std::cout &lt;&lt; className;</code> in the callback.
  classNames provided from the callback are:</p>
  <pre><code>RCLIENT
  CefBrowserWindow
  Chrome_WidgetWin_0
  Chrome_RenderWidgetHostHWND
  </code></pre>
  <p>Further using <code>FindWindowA()</code> with these class names doesn't provide anything useful.</p>
  <p><a href="https://stackoverflow.com/questions/25943872/enumchildwindows-never-calls-its-callback">Research for EnumChildWindows().</a>
  I notice here the className in the callback is specifically for the child window. This is what I'm trying to find. Currently I'm just searching for the parent windows className.</p>

  <p>UPDATE</p>
  <p><a href="https://i.imgur.com/2hrzubp.png" rel="nofollow noreferrer">I used inspect to find some more information.</a></p>
  <p>It seems like from this <a href="https://stackoverflow.com/a/41175036/14199954">answer</a>, communicating with these fields are impossible.</p>
