Adding statusbar in Win32 application

I want to add a statusbar to my Win32 application. I found out that I can use CreateStatusWindow function. I works fine until I re-size my window. See a part of my block of code:

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   HWND hWnd;

   hInst = hInstance; // Store instance handle in our global variable

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   if (!hWnd)
   {
      return FALSE;
   }


   CreateStatusWindow(WS_CHILD | WS_VISIBLE, _T("Welcome to SpyWindows"), hWnd, 9000);

   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}

Here are two printscreens of my application main window:

What can I do to have a good status bar? (I also want to divide it in more areas)

The documentation mentions that the status bar will recompute its appropriate position and size when it receives a WM_SIZE message:

The window procedure automatically adjusts the size of the status bar whenever it receives a WM_SIZE message. Typically, when the size of the parent window changes, the parent sends a WM_SIZE message to the status bar.

So, the simplest way to achieve this is to relay to the status bar the WM_SIZE messages received by the parent (with SendMessage(), from its window procedure). The message parameters do not matter, as the status bar does not use them in its computations.
