This snippet is about how to set the icon of a RenderWindow.

For questions use [http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=9375|this thread].

{CODE(wrap="1", colors="c#")} [DllImport("user32.dll")]
 private static extern int SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);
 [DllImport("user32.dll")]
 private static extern int DrawMenuBar(int currentWindow); 
 
 private const int WM_SETICON = 0x80;
 private const int ICON_SMALL = 0;
 
 /// <summary>
 /// Sets the icon of a window using it's handle.
 /// </summary>
 /// <param name="icon">The System.Drawing.Icon you wish to use as the window's icon.</param>
 /// <param name="hwnd">The window's handle.</param>
 public static void SetIcon(System.Drawing.Icon icon, IntPtr hwnd)
 {
     if (icon == null || hwnd == null || hwnd == IntPtr.Zero) // check parameters
         return;
     SendMessage(hwnd, WM_SETICON, (IntPtr)ICON_SMALL, (IntPtr)icon.Handle); // Set the icon with SendMessage
     DrawMenuBar((int)hwnd); // Force windows to update the icon
 }{CODE}
You can get the handle of a RenderWindow instance like this:
{CODE(wrap="1", colors="c#")} IntPtr hwnd = new IntPtr();
 MyRenderWindow.GetCustomAttribute("WINDOW", out hwnd);{CODE}
Then it's just a matter of
{CODE(wrap="1", colors="c#")} SetIcon(new System.Drawing.Icon("myicon.ico"), hwnd);{CODE}
Another interesting thing you could do is create an [http://msdn.microsoft.com/en-us/library/bb383977.aspx|extension method] for RenderWindow...
