HRESULT hResult;
    hResult=pd3dDevice->CreateOffscreenPlainSurface(1024,768,
        D3DFMT_X8R8G8B8,
        D3DPOOL_DEFAULT ,
        &srcSurface,
        NULL);

    if(FAILED(hResult))
        return false;

    IDirect3DSurface9 *surface;
    hResult=D3DXLoadSurfaceFromFile(surface,NULL,
        NULL,"abc.bmp",NULL,D3DX_DEFAULT,0,NULL);
    if(FAILED(hResult))
        return false;

我检查过了，只是D3DXLoadSurfaceFromFile这里出错，我是照着电子书教程写的，我觉得问题出在surface这个指针
应该如何获取这个指针，高手请教教，或者是别的地方错了，
