那个ID3DXBuffer*  不会操作

问题 补充
 1 BOOL ScreenShot(LPDIRECT3DDEVICE9 lpDevice, HWND hWnd, TCHAR* fileName)
 2 {
 3     HRESULT hr;
 4     
 5     // Get adapter display mode
 6     D3DDISPLAYMODE mode;
 7     if (FAILED(hr = lpDevice->GetDisplayMode(0, &mode)))
 8         return hr;
 9
10     // Create the surface to hold the screen image data
11     LPDIRECT3DSURFACE9 surf;
12     if (FAILED(hr = lpDevice->CreateOffscreenPlainSurface(mode.Width,
13         mode.Height, D3DFMT_A8R8G8B8, D3DPOOL_SYSTEMMEM, &surf, NULL))) //注意第四个参数不能是D3DPOOL_DEFAULT
14     {
15         return hr;
16     }
17
18     // Get the screen data
19     if (FAILED(hr = lpDevice->GetFrontBufferData(0, surf)))
20     {
21         surf->Release() ;
22         return hr ;
23     }
24
25     // area to capture
26     RECT *rect = NULL ;
27
28     WINDOWINFO windowInfo ;
29     windowInfo.cbSize = sizeof(WINDOWINFO) ;
30
31     if(hWnd) // capture window
32     {
33         GetWindowInfo(hWnd, &windowInfo) ;
34         rect = &windowInfo.rcWindow ;
35     }
36
37     // Save the screen date to file
         ID3DXBuffer* pBuffer=NULL;
38     hr = D3DXSaveSurfaceToFileInMemory (pBuffer, D3DXIFF_BMP, surf, NULL, rect);
     


后就不会了  pBuffer 怎么转成 HBITMAP
