LPD3DXBUFFER pD3DXMtrlBuffer;
 
// Load the mesh from the specified file
if( FAILED( D3DXLoadMeshFromX( "Tiger.x", D3DXMESH_SYSTEMMEM, 
            g_pd3dDevice, NULL, &pD3DXMtrlBuffer, NULL,
			&g_dwNumMaterials, &g_pMesh ) ) )
    {
    // If model is not in current folder, try parent folder
    if( FAILED( D3DXLoadMeshFromX( "..\\Tiger.x",      
            D3DXMESH_SYSTEMMEM, g_pd3dDevice, NULL, 
            &pD3DXMtrlBuffer, NULL, &g_dwNumMaterials, 
            &g_pMesh ) ) )
        {
            MessageBox(NULL, "Could not find tiger.x",
			           "Meshes.exe", MB_OK);
            return E_FAIL;
        }
    }

Cependent à la compilation j'ai des erreurs

h:\c++\vs\directx\main.cpp(16) : error C2065: 'LPD3DXBUFFER' : undeclared identifier
h:\c++\vs\directx\main.cpp(16) : error C2146: syntax error : missing ';' before identifier 'pD3DXMtrlBuffer'
h:\c++\vs\directx\main.cpp(16) : error C2065: 'pD3DXMtrlBuffer' : undeclared identifier

Il me manque un header ?
Voila la source de ma fenêtre
