...Buttons using BS_BITMAP

I'm trying to create a button with the BS_BITMAP flag, but I don't know how to set the bitmap. I would like to avoid using CButton; I use Dev-C++. Could I see some example source?

    :

    I just realized how simple the answer was. For those of you who are wondering this, I'll explain. You basically have to create the button with the BS_BITMAP flag, ( of course ) then you send a BM_SETIMAGE message to the handle of the button. You need to create a *.h file ( I'll call it "resource.h" ):
    _______________________________________________________________________

    #define IMG_BITMAP

    _______________________________________________________________________

    ...A *.rc file ( assuming resource.h and bitmap.bmp exsist ) :

    _______________________________________________________________________

    #include "resource.h"

    IMG_BITMAP BITMAP "bitmap.bmp"

    _______________________________________________________________________

    ...And the *.cpp file looks like this:

    _______________________________________________________________________

    #include
    #include

    #include "resource.h"

    #define IDB_BUTTON 200

    /* Declare Windows procedure */
    LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

    /* Make the class name into a global variable */
    char szClassName[ ] = "WindowsApp";

    HINSTANCE g_hInst;

    int WINAPI WinMain (HINSTANCE hThisInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpszArgument,
    int nFunsterStil)

    {

    g_hInst = hThisInstance;

    HWND hwnd; /* This is the handle for our window */
    MSG messages; /* Here messages to the application are saved */
    WNDCLASSEX wincl; /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */
    wincl.style = CS_DBLCLKS; /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (hThisInstance, "BS_BITMAP.ico");
    wincl.hIconSm = LoadIcon (hThisInstance, "BS_BITMAP.ico");
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL; /* No menu */
    wincl.cbClsExtra = 0; /* No extra bytes after the window class */
    wincl.cbWndExtra = 0; /* structure or the window instance */
    /* Use Windows's default color as the background of the window */
    wincl.hbrBackground = CreateSolidBrush(RGB(255, 0, 128));

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
    return 0;
