  We will review some results based on the EROS and the on going EROS-2
microlensing surveys to search for dark matter in the Galactic halo via
microlensing effects on LMC/SMC stars. Microlensing surveys provide systematic
observations for millions of stars over a long period in both Magellanic Clouds
and give birth to very powerful database. We will quickly review the results
obtained on pulsating stars and we will detail the similarity and differences
of the Herbig Ae/Be stars in the Magellanic Clouds compared to their Galactic
counterpart.
