求高手指点D3DXLoadSurfaceFromFile函数错误原因

[a86632678]

求高手帮解释这个基本的 D3DXLoadSurfaceFromFile函数为什么不行
库连接已经设置好了的，d3d9.lib;d3d9x.lib都已经有了

#include <Windows.h>
#include <d3d9.h>
#include <d3dx9.h>
#include <iostream>
using namespace std;

#define KEY_DOWN(ck_code) ((GetAsyncKeyState(vk_code)&0x8000)?1:0)

#define SCREENW 1024
#define SCREENH 768

LPDIRECT3D9 d3d = NULL;
LPDIRECT3DDEVICE9 d3ddev = NULL;

LPDIRECT3DSURFACE9 surface =NULL;
LPDIRECT3DSURFACE9 backbuffer =NULL;
bool gameover=false;


int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstanace,LPSTR lpCmdLine,int nCmdShow)
{

HRESULT result =D3DXLoadSurfaceFromFile(
surface,
NULL,
NULL,
"E:\\workspace\\GameT\\testD3DLOADSURFACE\\testD3DLOADSURFACE\\c.bmp",
NULL,
D3DX_DEFAULT,
0,
NULL);
}

D3D忘差不多了。是不是缺这个。
LPDIRECT3DSURFACE9 g_Surface =NULL;
D3DXIMAGE_INFO Info;
D3DXGetImageInfoFromFile("D:\image.jpg", &Info);
g_pd3dDevice->CreateOffscreenPlainSurface(Info.Width, Info.Height, Info.Format, &g_Surface, NULL);
D3DXLoadSurfaceFromFile(g_Surface, NULL, NULL, "D:\image.jpg", NULL, D3DX_FILTER_NONE, 0xFF000000, NULL);

。加上这个之后多了D3DXGetImageInfoFromFile 这个函数的错误、 之前那个 D3DXLoadSurfaceFromFile函数错误还在。。 求真相
