我在加载位图的时候遇到了困难。参考的 sea_bug 翻译的〈载入位图文件到 DirectDraw〉源代码如下：
IDirectDraw2 *lpdd ;
LPDIRECTDRAWSURFACE7 lpddsTest;
void CreateSurface(LPDIRECTDRAWSURFACE7 *lpSource, int xs, int ys)
{
        DDSURFACEDESC2 ddsd;

        ZeroMemory(&ddsd, sizeof(ddsd));
        ddsd.dwSize = sizeof(ddsd);
        ddsd.dwFlags = DDSD_CAPS | DDSD_WIDTH | DDSD_HEIGHT;
        ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN;
        ddsd.dwWidth = xs;
        ddsd.dwHeight = ys;
        lpdd->CreateSurface(&ddsd, lpSource, NULL);
}
void DrawHBitmap(IDirectDrawSurface7 *lpSurface, HBITMAP hBitmap, int x, int y, int width, int height)
{
        HDC hdcImage;
        HDC hdc;
        BITMAP bm;

        if (lpSurface == NULL || hBitmap == NULL)
                return;
        lpSurface->Restore();

        hdcImage = CreateCompatibleDC(NULL);
        SelectObject(hdcImage, hBitmap);

        GetObject(hBitmap, sizeof(bm), &bm);
        width = width == 0 ? bm.bmWidth : width;
        height = height == 0 ? bm.bmHeight : height;

        lpSurface->GetDC(&hdc);
        BitBlt(hdc, x, y, width, height, hdcImage, 0, 0, SRCCOPY);
        lpSurface->ReleaseDC(hdc);
        DeleteDC(hdcImage);
}
void CreateBitmapSurface(LPDIRECTDRAWSURFACE7 lpSurface, char *fname, int xs, int ys)
{
        HBITMAP hBitmap;

        CreateSurface(&lpSurface, xs, ys);
        hBitmap = LoadImage(NULL, fname, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
        DrawHBitmap(lpSurface, hBitmap, 0, 0, xs, ys);
        DeleteObject(hBitmap);
}

错误提示为：
error C2664: 'CreateSurface' : cannot convert parameter 1 from 'struct _DDSURFACEDESC2 *' to 'struct _DDSURFACEDESC *'

将IDirectDraw2 *lpdd ;改为IDirectDraw7 *lpdd ;
