使用directdraw如何将一块bitmap格式的数据放到surface中？

请高手指教！

extern C IDirectDrawSurface * DDLoadBitmap(IDirectDraw *pdd,
LPCSTR szBitmap, int dx, int dy)
{
HBITMAP hbm;
BITMAP bm;
DDSURFACEDESC ddsd;
IDirectDrawSurface *pdds;

//
// This is the Windows CE part.
// Try to load the bitmap as a resource.
// If that fails, try it as a file.
//
hbm = (HBITMAP)LoadImage(
GetModuleHandle(NULL), szBitmap,
IMAGE_BITMAP, dx, dy, LR_CREATEDIBSECTION);

if (hbm == NULL)
hbm = (HBITMAP)LoadImage(
NULL, szBitmap, IMAGE_BITMAP, dx, dy,
LR_LOADFROMFILE|LR_CREATEDIBSECTION);

if (hbm == NULL)
return NULL;

//
// Get the size of the bitmap.
//
GetObject(hbm, sizeof(bm), &bm);

//
// Now, return to DirectX function calls.
// Create a DirectDrawSurface for this bitmap.
//
memset(&ddsd, 0, sizeof(ddsd));
ddsd.dwSize = sizeof(ddsd);
ddsd.dwFlags = DDSD_CAPS | DDSD_HEIGHT |DDSD_WIDTH;
ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN;
ddsd.dwWidth = bm.bmWidth;
ddsd.dwHeight = bm.bmHeight;

if (pdd->CreateSurface(&ddsd, &pdds, NULL) != DD_OK)
return NULL;

DDCopyBitmap(pdds, hbm, 0, 0, 0, 0);

DeleteObject(hbm);

return pdds;
}

这些函数都是开发包里自带的
看看开发包的例程，我就是在那找的
