[Dev-C++] Problems with CreateWindow.

[hhh h. <the...@ho...>]

Hi all,

  I am now learning about the WIN32 API functions, and I tryied to create an 
application that listed the windows that are child to the desktop.
  I got the code to work listing all the windows, and then i started to 
designed a interface for my program.
  Well, to make a long story short , I tryied to display a Image in my 
parent window, by creating a child window ( with ws_child  ) to my main one 
, and LoadImage into it.
However my image never gets displayed.

Ps:
I checked the handles and they seem correct. Do keep in mind that i'm new to 
windows API, if the code is too buggy.

[ the image is : 800x110 , .bmp ]
(Bellow i give a snippet of the code that I think relevant.)

--------------------------------------------------------
//Declaration of vars
HANDLE hImage;
HWND hwnd;
HWND ChildWnd5;
hThisInstance is arg to WinMain... nothing new here


Parent Window:

hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           "MyClass",         /* Classname */
           "Window Lister",       /* Title Text */
           WS_CAPTION | WS_BORDER | WS_SYSMENU | WS_MINIMIZEBOX, /* default 
window */
           CW_USEDEFAULT,       /* Windows decides the position */
           CW_USEDEFAULT,       /* where the window ends up on the screen */
           900,                 /* The programs width */
           800,                 /* and height in pixels */
           HWND_DESKTOP,        /* The window is a child-window to desktop 
*/
           NULL,                /* No menu */
           hThisInstance,       /* Program Instance handler */
           NULL                 /* No Window Creation data */
           );
--------------------------------

My Child Window :

ChildWnd5 = CreateWindowEx (
              WS_EX_CLIENTEDGE ,
               "Static",
               "",
               WS_CHILD | SS_BITMAP  | WS_VISIBLE ,
               0,0,800,110,
               hwnd,
               0,
               hThisInstance,
               0
           );

----------------------------

Code Part :

if (ChildWnd5 = NULL)
   MessageBox ( hwnd, "Child Window Handle is NULL", "Lin 131", MB_OK  );
hImage = LoadImage ( hThisInstance , "banner.bmp", IMAGE_BITMAP, 800, 110, 
LR_LOADFROMFILE );
if (hImage == NULL)
     MessageBox ( hwnd, "The image handle is NULL.", "Lin 151", MB_OK  );
SendMessage(
            ChildWnd5,
            STM_SETIMAGE,
            IMAGE_BITMAP,
            (LPARAM) hImage
           );
ShowWindow(ChildWnd5,SW_SHOWNORMAL);
UpdateWindow(ChildWnd5);
