title: How to group Windows API constants
body: <p>When defining Windows API const values, is it better to have them as const</p>
  
  <pre><code>public const int SW_HIDE = 0;
  public const int SW_SHOWNORMAL = 1;
  public const int SW_NORMAL = 1;
  public const int SW_SHOWMINIMIZED = 2;
  public const int SW_SHOWMAXIMIZED = 3;
  public const int SW_MAXIMIZE = 3;
  public const int SW_SHOWNOACTIVATE = 4;
  public const int SW_SHOW = 5;
  public const int SW_MINIMIZE = 6;
  public const int SW_SHOWMINNOACTIVE = 7;
  public const int SW_SHOWNA = 8;
  public const int SW_RESTORE = 9;
  public const int SW_SHOWDEFAULT = 10;
  public const int SW_MAX = 10;
  
  [DllImport( "user32.dll" )]
  public static extern bool ShowWindow( HandleRef hWnd, int nCmdShow );
  </code></pre>
  
  <p>or to group them together as an enum.</p>
  
  <pre><code>public enum SW {
    SW_HIDE = 0,
    SW_SHOWNORMAL = 1,
    SW_NORMAL = 1,
    SW_SHOWMINIMIZED = 2,
    SW_SHOWMAXIMIZED = 3,
    SW_MAXIMIZE = 3,
    SW_SHOWNOACTIVATE = 4,
    SW_SHOW = 5,
    SW_MINIMIZE = 6,
    SW_SHOWMINNOACTIVE = 7,
    SW_SHOWNA = 8,
    SW_RESTORE = 9,
    SW_SHOWDEFAULT = 10,
    SW_MAX = 10
  }
  
  [DllImport( "user32.dll" )]
  public static extern bool ShowWindow( HandleRef hWnd, SW nCmdShow );
  </code></pre>
