保存D3D中当前视图

    m_pd3dDevice为是一个device class，相应代码如下：LPDIRECT3DDEVICE9

BOOL SaveViewToFile(CString strFileName){IDirect3DSurface9 *back = NULL;// 获得BackBuffer的D3D Surfacem_pd3dDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &back);// 保存成BMP格式D3DXSaveSurfaceToFile(strFileName, D3DXIFF_BMP, back, NULL, NULL);// 释放Surface，防止内存泄漏SAFE_RELEASE(back);return TRUE;}

   PS ： 使用 D3DXSaveSurfaceToFile需要添加 #include <d3dx9.h>.
