DirectDraw Problem

Hello. I am trying to learn to use direct draw. I am having a problem getting a bitmap to load. Here's the relevant code.

//Globals
LPDIRECTDRAW lpdd;
LPDIRECTDRAWSURFACE lpddsprimary;
LPDIRECTDRAWSURFACE lpddsback;
LPDIRECTDRAWSURFACE lpddsbitmap;
LPDIRECTDRAWPALETTE lpddpal;
LPDIRECTDRAWCLIPPER lpddclipper;
PALETTEENTRY color_palette[256];
DDSURFACEDESC       ddsd;
DDSCAPS             ddscaps;
HRESULT             ddrval;

Direct Draw initialization

if (DirectDrawCreate(NULL, &lpdd, NULL) !=DD_OK)
        return(0);
    
    if((lpdd->SetCooperativeLevel(main_window_handle,DDSCL_ALLOWMODEX | DDSCL_FULLSCREEN | DDSCL_EXCLUSIVE | DDSCL_ALLOWREBOOT))!=DD_OK)
        return(0);
    
    if((lpdd->SetDisplayMode(SCREEN_WIDTH,SCREEN_HEIGHT,SCREEN_BPP))!=DD_OK)
        return(0);
    
    memset(&ddsd,0,sizeof(ddsd));
    ddsd.dwSize         = sizeof(ddsd);
    ddsd.dwFlags        = DDSD_CAPS | DDSD_BACKBUFFERCOUNT;
    ddsd.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE | DDSCAPS_FLIP | DDSCAPS_COMPLEX;
    ddsd.dwBackBufferCount = 1;
    
    if (lpdd->CreateSurface(&ddsd,&lpddsprimary,NULL)!=DD_OK)
        return(0);
     
    ddscaps.dwCaps = DDSCAPS_BACKBUFFER;
    
    lpddsprimary->GetAttachedSurface(&ddscaps,&lpddsback);
    
    memset(&ddsd,0,sizeof(ddsd));
    ddsd.dwSize         = sizeof(ddsd);
    ddsd.dwFlags        = DDSD_CAPS | DDSD_WIDTH | DDSD_HEIGHT;
    ddsd.dwWidth        = 34;
    ddsd.dwHeight       = 34;
    ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN;
    
    if (lpdd->CreateSurface(&ddsd,&lpddsbitmap,NULL)!=DD_OK)
        return(0);
     
    if ( ( lpddsbitmap = DDLoadBitmap( lpdd, "test.bmp", 0, 0) ) == NULL )
    return FALSE;   

Main loop

RECT source_rect,dest_rect;
    
    source_rect.left    = 0;
    source_rect.top     = 0;
    source_rect.right   = 34;
    source_rect.bottom  = 34;
    
    dest_rect.left      = 50;
    dest_rect.top       = 50;
    dest_rect.right     = 84; 
    dest_rect.bottom    = 84;
    
    
  
    if (KEY_DOWN(VK_ESCAPE) || KEY_DOWN(VK_SPACE))
    PostMessage(main_window_handle, WM_DESTROY,0,0);
    
    memset(&ddsd,0,sizeof(ddsd));
    ddsd.dwSize = sizeof(ddsd);
    
    lpddsback->Lock(NULL,&ddsd,DDLOCK_SURFACEMEMORYPTR | DDLOCK_WAIT,NULL);
    
    if ( FAILED( lpddsback->BltFast( 0, 0, lpddsbitmap, &source_rect, DDBLTFAST_WAIT ) ) )
    return FALSE;
    
    lpddsback->Unlock(ddsd.lpSurface);
    
    while(lpddsprimary->Flip(NULL,DDFLIP_WAIT)!=DD_OK);

The code compiles fine. I just get nothing on the screen intead of the bitmap. I am using the ddutil.cpp functions from MS for my bitmap loading. Any help would be appreciated. Thanks,
