{
  Creates an TIcon object from a TBitmap.
  Handy for dynamically updating your application's icon.
  I use it often to update my application's tray icon.

  Erzeugt ein TIcon aus einem TBitmap Objekt.
  Es ist nützlich, um das Icon der Applikation dynamisch zu
  verändern.
}

function CreateIconFromBitmap(Bitmap: TBitmap; TransparentColor: TColor): TIcon;
begin
  with 
TImageList.CreateSize(Bitmap.Width, Bitmap.Height) do
  begin
    try
      
AllocBy := 1;
      AddMasked(Bitmap, TransparentColor);
      Result := TIcon.Create;
      try
        
GetIcon(0, Result);
      except
        
Result.Free;
        raise;
      end;
    finally
      
Free;
    end;
  end;
end;
