title: After createwindow(...), how to give the window a color?
body: <p>I have created a window whose handle is handle_parent. Then I created a child window as following:</p>
  
  <pre><code>hwnd_child = CreateWindow(child_class_name, _T(""),
  WS_CHILDWINDOW, 0, 0, 0, 0, hwnd_parent, (HMENU)0, ghinst, NULL);
  ShowWindow(win-&gt;hwndSplitterBar, SW_SHOW);
  UpdateWindow(win-&gt;hwndSplitterBar);
  </code></pre>
  
  <p>I would like to set the color of child window "child". If I do nothing, the color is grey by default.
  How could I set its color? I would like to keep the color as black permanent, do change in anycase.</p>
