Direct3D9 SetRenderTarget usage

You can render to a texture as follows:

1 Get the surface (IDirect3DSurface9) interface of the texture you want to render to
2 Get the old surface that is currently being rendered to
3 Set the texture''s surface as the render target
4 Render stuff as usual
5 When done, set the old surface as the render target

IDirect3DSurface9* pSurf, *pOldTarget;

// 1

pTexture->GetSurfaceLevel( 0, &pSurf );

// 2

pDevice->GetRenderTarget( 0, &pOldTarget );

// 3

pDevice->SetRenderTarget( pSurf );

// 4


// 5

pDevice->SetRenderTarget( pOldTarget );

// Dont forget to release surface

pSurf->Release();
pOldTarget->Release();

I dont believe Im forgetting anything...
